Exactly how effective are injury-prevention programs in soccer? El Paso, TX.s Scientific chiropractor Dr. Alexander Jimenez looks at the very latest evidence…
Football is the world’s most popular team sport. Injuries are a significant issue for both amateur and professional players. Indeed, previous research has estimated that soccer players are among the most injury-prone athletes having an estimated injury rate of 17-24 accidents per 1000 playing hours(1). Nineteen per cent of all sports injuries which exist in the Netherlands are because of soccer(two) and in Britain alone, the expense of therapy and time lost from work owing to football injuries is estimated to be approximately #1billion annually(1)!
In a landmark study, researchers followed two Champions League teams and gathered data on 2,229 players over seven seasons to examine the injury profile of muscular injuries in soccer players(3). They also analyzed the gamers’ training schedules and data out of their games to construct a detailed picture of the injury risks that were associated. The findings were as follows:
2,908 muscle injuries have been enrolled;
Normally, a player sustained 0.6 muscle injuries each season (equating to around 15 muscle injuries per season at a squad of 25 players);
Muscle injuries constituted 31 percent of all injuries and caused 27% of the total injury lack;
Ninety-two per cent of muscle injuries affected the four Big muscle groups of the lower limbs: hamstrings (37 percent), adductors (23 percent), quadriceps (19%), and calf muscles (13%);
Sixteen per cent of the muscular injuries were re-injuries; nonetheless, these re-injuries caused significantly longer absences than did the first injuries.
The prevalence of muscular injury increased with age.
The exact same group of researchers also carried out a follow-up study (published in 2013) in which they sought to establish the consequences of fixture congestion on injury rates among the gamers(4). Time-loss and exposure injuries were enrolled prospectively from 27 teams over 11 seasons. Matches were grouped based on the amount of recovery days before each match and the accident rates were compared between classes. The results showed that compared to a recovery interval of more or six days, muscular injury rates and overall injury rates were raised in league matches where players had had four or less recovery days.
Given the high levels of trauma among football players (a risk that is increased during periods of match congestion) and the financial pressure of the modern game, it’s perhaps unsurprising that medical team caring for players find that treatment of injuries in players is quite a frustrating and also a never-ending struggle. In addition, it clarifies why some players end up returning to contest prior to the injury has healed completely, setting the stage for injury recurrence, together with protracted absence of this participant from competition and training.
Injury Treatment
Treating injuries in football is both time- consuming and expensive, particularly at the elite level. And while there’s a large literature on the epidemiology of sports injuries, established protocols for treating muscular injuries and assessment criteria for imaging, and a number of clinical and functional tests that could assist the health staff in deciding the optimal point where an athlete can be safely returned to full participation(5,6), the current guidelines haven’t translated into a significant reduction in muscle injury levels in professional sports such as soccer.
To simplify things further, the evidence indicates a new injury often occurs within a couple of weeks after return to contest, and typically costs the player more lost playing time than the key injury(7). The most probable reasons for this observation are likely associated with bodily alterations following the first injury, such as muscle stiffness and/or fatigue, scar tissue formation, biomechanical alterations, neuromuscular inhibition, as well as inadequate treatment — for instance, overly aggressive or incomplete rehabilitation(8-10).
Injury-Prevention Programs
Even armed with knowledge that is up-to-date and the best technology is fraught with difficulty. Remembering the old adage that ‘an ounce of prevention is worth a pound of cure’, a alternative that is far better to attempt to prevent injuries from happening in the first place with an injury-prevention program. This is easier said than done. It is correct that there is an abundance of literature on the effectiveness of methods to avoid harm recurrence and muscle injury, such as enhancing flexibility eccentric and concentric exercises and drills. Despite this and apps like FIFA’s ‘The II’ (see Box 1), the incidence of muscle injuries generally, and the recurrence rate particularly, remains stubbornly high(11-16).
More recent studies indicate that in higher levels of functionality, there might not be much in the way of significant added benefits, while some early study appeared to give evidence for the efficacy of programs in football, as described in box 1. At a follow up to the study described above(18) and that was published this past year, the same group of investigators looked to see if an injury prevention program comprising 10 exercises designed to enhance stability, muscle strength, co-ordination, and versatility of the back, hip and leg muscles (FIFA’s ‘The II’) was effective concerning reducing injury levels and whether it offered any advantages in terms of reducing the related costs of following treatment for injuries that did occur(19).
From the analysis, 479 adult male amateur gamers aged 18-40 years have been split into two classes: the intervention group had been taught to do exercises focusing on core stability, bizarre training of thigh muscles, proprioceptive training, dynamic stabilization, and plyometrics with straight-leg orientation at every training session (2-3 sessions per week) through one season. The management team, meanwhile, continued their usual warm up.
As in the previous study, there were no significant differences in the percentage of players that are injured and injury rates between the two groups. What was intriguing was that in the intervention group, the price of injury treatment was 256 per participant. In the control group nonetheless treatment costs were twice at $606 per participant. The investigators commented that the cost savings in the intervention group may be the result of a rate of knee injuries, which have costs because of more lengthy rehabilitation periods and much more time lost at work compared to a number of different injuries.
Meanwhile, another study on an injury- prevention program (based on The II) in male amateur players had been printed in the end of last year(20). It discovered that (like the previous studies), an intervention program did not decrease the incidence of harm throughout the course of a season. However, such as the study, the players in the intervention group did incur less health care costs, although a justification for this finding wasn’t given. As if to validate the confusion surrounding the value of injury-prevention programs for football players, then a recently published systematic overview of all of the previous studies released thus far fought to achieve a definitive conclusion(21). Six studies involving a total of 6,099 participants met the inclusion criteria and the results of these were conflicting two of the six studies (among large and one of moderate quality) reported a decrease in injury rates that were actual. Four of the six research an ‘preventive effect’, even though the effect of a single study wasn’t statistically significant. Possible reasons for these contradictory findings might be subject choice (sex and level of ability), differences between the intervention programs implemented (content, training frequency and duration) and compliance with this application. What’s clear, however, is that studies investigating the type and seriousness of exercises within an injury-prevention program are still required to reduce the incidence of accidents in soccer efficiently.
Good News On Prevention
Since the review study cited previously(21) was printed, two quite newly published studies on injury-prevention apps in soccer seem to provide more encouraging news — for muscle injuries at least. In one, researchers studied elite players competing over two consecutive seasons, where the first (2008-2009) function as intervention period and the second, the management period (2009-2010)(22). In total, 26 (08/09) and 23 (09/10) elite male pro football players competing within the Scottish Premier League and European competition participated. The accident prevention training program was conducted twice weekly to the entirety of this season (58 avoidance sessions) and the results were compared with the control (no injury-prevention program) year.
On first inspection, the results were disappointing, showing an increase in the complete number of accidents within the intervention period (88 vs 72). But this was largely because of the greater quantity of contusion injuries sustained inside the intervention season (44) compared with control season (23). Assessing like for muscular injuries that were significantly fewer were observed during the intervention season, which had been even more impressive given the larger squad size at the intervention season.
Another newly published study by Italian scientists who researched the effect of a two-tiered injury-prevention program on initial injury and re-injury prevalence in 36 elite male football players also causes encouraging reading(23). During the season prior to that examined in the study, there had been 27 muscle injuries in the group, which accounted for 58.7 percent of the total injuries: 13 of these had occurred throughout practice and 14 during matches. The general incidence of muscular injuries was 5.6 injuries/1000 hours of training/playing exposure and the effect was 106.4 times absence/1000 hours exposure.
To try and decrease the speed of injury through the following season, the team doctor (also among the study’s authors) found an injury-prevention program, conducted 2-3 times per week. This consisted of two elements: a collection of core stability exercises conducted by the whole group prior to each practice session (see Box 2) along with an individualized injury prevention program, which has been started after assessment with kinesiologic and diagnostic tests. At the start of the year, every athlete underwent testing of leg flexibility using the Ober evaluation, Thomas evaluation and straight-leg-raising [SLR] test(24-26). The prone instability test(27) was completed to show spinal instability along with the stork test (28,29) to assess sacroiliac dysfunction. Quadriceps and hamstring strength were measured isokinetically and attention was directed in evaluation of immunity of gluteus medius’ power.
The injuries that happened based on MRI and clinical imaging findings were diagnosed by the medical team. An injury was defined as though it caused the participant to miss the next training session or match, and happened during a scheduled training session or match. An injured player was defined injured before the club medical staff cleared him for participation. Re-injuries were described as those that occurred as those that occurred at the same website no longer than three months following the player had returned to full involvement at early re-injuries and exactly the exact same site.
Results
Throughout the intervention season, a total of 64 injuries occurred — 36 (56 percent) during practice and 28 (44%) during matches. Of them, 20 were muscle injuries, accounting for 31.3 percent of the total injuries; 14 of which occurred during practice and 6 during games. In all, three re-injuries happened and (15 percent of overall muscle injuries) and there were not any premature re-injuries. In comparison with the preceding season with no intervention-program set up, there was a reduction in the number of times and muscle injuries . Specifically, whereas muscle injuries accounted for 31 percent of harms they accounted for 59% of all injuries. Significantly, the number of injuries per 1000 hours of training and playing time was reduced by over half of 5.6 to 2.5. Meanwhile, the number of days fell by nearly two-thirds 106 into 37. The investigators put the success of this intervention down to three key aspects:
An injury prevention program that comprised of core stability exercises similar to those in ‘The II’ program but which differed in its two-tiered arrangement (group and individual sessions), allowing for intense and special training. In contrast, the combined results in research into The II app are probably because of the non- special content and ineffective intensity.
The program’s continuity of commitment by the players to both the group and individual areas.
The addition of bizarre hamstring training in the group program (2 sets of 5 repetitions per week) combined with all the personalized application for players with a history of injury.
Using ice baths in the conclusion of every training session
The investigators cautioned that their study would have included a larger number of topics, but the data still showed a critical progress by the prior year over that. They also argued that by increasing the number of group and individual prevention training sessions, the outcomes could be enhanced.
Summary & Recommendations
Injury treatment in aggressive soccer is equally costly and time-consuming also given the pressures of the game, injury avoidance is more important than ever. But, despite extensive published literature on harm prevention strategies and initiatives such as FIFA’s ‘The II’, the injury rates in soccer remain high, especially in the higher levels.
The latest research indicates that while overall injury prevention programs such as The II might reduce the incidence of trauma in amateur gamers, especially by reducing the incidence of knee injury. However, they will probably not benefit professional players or level. Instead, combining a more individualized approach (using a far greater emphasis on particular exercises determined by kinesiologic and diagnostic testing) with team sessions seems to be desirable. Additionally, it is important that gamers are ‘on-board’ with almost any program and take part regularly (at least twice weekly) to achieve all the potential advantages.

The previous rehab masterclass on Lisfrancs injuries highlighted the pathogenesis of injuries, the midfoot joint’s relevant factors, and typical injury mechanisms were presented along with diagnostic findings. In this masterclass scientific specialist Dr. Alexander Jimenez discusses the management of Lisfranc injuries…
Management
After the initial injury, it may not be clear exactly what harm the foot has been done to by the athlete. Both athlete and sports medicine staff may confuse. The athlete with subtle stage 1-type injuries will try to ‘run off’ the pain. As they continue and fail to reevaluate they will stop training/competition.
When an injury into the Lisfranc is suspected, the first MTP joint ought to be assessed to exclude a ‘toe’ injury and the ankle checked to exclude an ankle injury. They crutches till they could be properly analyzed and remain non-weightbearing ideally with an Aircast boot and need to ice the foot aggressively.
Non-operative�Treatment of Lisfranc Injuries
A stage 1 accident that’s functionally secure could be handled with a non-weight posture boot or cast for a first two weeks. They can be analyzed for tenderness on palpation over the TMT joint at this time and follow-up x-rays will be required to exclude any latent diastasis of the second and first metatarsal space. If pain-free on palpation and x ray is normal, they could have the weight bearing status assessed using complete weight bearing foot flat and position is raised by a toe. If that is normal they can stay out of the boot using a custom made orthotic and rehabilitation and return to conditioning may begin.
Then the boot is reapplied, if the foot stays painful to palpate or if they neglect raise test and they stay non weight bearing to partial weight bearing for a further four weeks.
For pain along with weightbearing status they’re reassessed in the stage. If these are uneventful then the rehabilitation and reconditioning stream is moved to by the athlete. If problematic they need to be assessed for postponed stabilisation.
The time period to get a injury that is secure could be a month recovery until return to play.
Operative Treatment Lisfranc Injuries
Stage 2 and stage 3 accidents need to have the midfoot surgically stabilized since they’re generally unstable injuries. Interestingly, Hummell et al (2010) recently clarified a successful result in a point 3 football player with non-operative treatment. The objective of surgery is to acquire a fantastic reduction to optimize functional results. Virtually all expert opinions relating to Lisfranc injuries emphasize the importance of gaining as to avoid long- term morbidity from the midfoot.
Myerson et al (1986) identified some things that result in poor outcome for example residual angulation between the metatarsals, diastasis greater than 2mm between the first and second metatarsals. Correcting these defects is essential to avoid long-term complications like chronic functional disability , post-injury arthritis and instability with walking.
To obtain reduction of the TMT joints reduction is usually necessary to remove any tissue for example little bone fragments or ligaments. Reduction is supported with fluoroscopy. Nevertheless, in instances percutaneous fixation can be accomplished if the dislocation can be reduced by the surgeon under fluoroscopy and stabilize the joints together with wires and screws. However, most will require an open reduction to properly visualize and access of the joints that are tarsometarsal.
The choice of hardware for surgery is debatable surgeons the choices are:
1. Cannulated screws;
2. Solid, Non-cannulated screws;
3. K wires;
4. Bridge plates for tarsometatarsal joints.
At a thorough literature review, Stavlas et al (2010) found that injuries to the first few metatarsals (lateral and middle column) react well with screw fixation, whereas harms to the fourth and fifth metatarsals (lateral column) may respond well with K wire fixation.
Post-Operative Rehabilitation
This will often involve a non-weight- bearing cast or boot to get the first 3 weeks with a CAM/Aircast boot used for the subsequent three to five weeks so that the athlete is complete weight. Weight is slowly built around the eight to twelve months post-operative interval so that in a custom-made orthotic the athlete can weight bear by 3 months that.
The hardware is often removed at 12-16 weeks post-op in lighter athletes and in heavier athletes (>200 lbs) it’s been suggested to take out the hardware in 24 weeks (Nunley and Verullo 2002).
Post-surgery the results are generally favourable. Nunley and Vertullo (2002) discovered that in stable stage 1 harms, great outcome was found with conservative treatment with athletes back to game at 11-18 weeks post-injury. Athletes with stage 2 injuries had good outcomes with ORIF and returned to play 12-20 weeks. Period 3 accidents were not described.
Physiotherapy
The athlete will see that the physiotherapist athletic coach weekly to regain mobility. Interventions will be necessary in addition to direct mobilizations to restore the accessory movements.
The therapist can also start intrinsic foot muscle exercises at approximately 8-10 weeks post-operative using the weight bearing exercises being postponed until week 12 post-operative. These exercises are designed to retrain the arch to be controlled by the foot muscles. Exercises that will satisfy this are towel scrunchies, cup drop, matt equilibrium and lunge exercises (see below).
The movement can be measured by the therapist regularly with knee.
1. Towel scrunchies. These have been used by therapists to strengthen the muscles that support the foot’s arch.
A. Place a towel onto a tiled or wooden floor (carpet will not work.
B. set the foot relaxed on the towel with all the foot in line with the knee and hip. The feet should be pointing directly ahead.
C. Initiate the movement by attempting to firstly raise the arch. Think about drawing the ball of the foot to the heel. You will see that the arch is going to lift.
D. Next use all the feet to loosen the towel under the foot.
E. Relax the foot and start again.
F. This exercise doesn’t cause any soreness the next day; the muscles should start to fatigue.
G. The development is seated, to standing on one leg and standing on two legs.
2. The cup drop. This can be an interesting and innovative way to integrate inherent arch muscle function and anti- pronator muscle function that is extrinsic using hip muscles that are hip, in particular the gluteus maximus and medius. During weight bearing, the hip is prevented by the gluteus medius muscle from rotating and adducting, and this action works well with the arch muscles preventing excess pronation.
A. Place a few small objects like marbles about one foot in front of your body.
B. Reach forward with the foot and also pick up the masonry with the feet. Of clawing at the masonry this activity will trigger the muscles.
C. Whilst holding the marble in the feet, circle the hip outwards into both sides of the body then behind the body and set the marble at a cup placed at 45 degrees to the cool.
D. It is necessary that the foot stays turned outwards as this retains the gluteus active.
3. The mat balance. This exercise incorporates these together with the arch muscles and adds contraction of the calf muscles both the gastrocnemius and soleus. The drill is done on a gentle matt, to create the exercise challenging. The mat surface generates an unstable situation, and there is mounting evidence that indicates that by incorporating a component of balance control to a rehab exercise may be necessary since the perturbations in movement excite all of the position feedback nerve endings which control proprioception. The nerve endings feedback to the muscle control system and also this potentiates the stimulation of their control muscles.
A.Place a soft mat in addition to a 6mm piece of timber or hard rubber mat. The thicker the mat that the harder the exercise.
B. Stand on the mat but just with the third, fourth and fifth feet connected with the matt. The first and second feet should be hanging unsupported from the mat.
C. This position of the foot makes a scenario whereby the foot wishes to turn in under gravity’s effect. The long pronation muscles in the shin and the muscles need to control the interior of the foot to keep it up and of the floor.
D. Attempting to keep equilibrium (and this will be hard when the matt is too soft), marginally boost the heel to participate the calf muscles.
E. Hold this position for 1-2 seconds and then slowly lower down to the beginning position.
F. Perform 3 sets of 10 repetitions.
4. Lunge with towel scrunchie. This workout is a high-level integration workout which combines gluteals and arch muscles whilst performing a exercise such as the lunge. This sort of exercise is done in late phase rehab prior to running as the muscle activation patterns more resemble what should happen in conducting concerning limb assistance — that is, the arch muscles control pronation, the quads control the knee and patella and the gluteus medius affirms the hip throughout foot strike.
A. Stand on a towel, very similar to Exercise 1 above.
B. Put some theratubing around a post and also wrapped round the upper tibia. The ring has to be guided to pull the tibia inwards, not outwards. This pulling in of the tibia can cause the top leg to follow along with this is imitating hip adduction and internal rotation. The goal of the exercise is to prevent it by maintaining the kneecap aligned with the next toes. The gluteals finally have to work to permit this to occur. Inwards and way would fall from the third toe, if they did not.
C. Gradually lower down into a lunge whilst keeping the monitoring of the kneecap over the next toe and also keeping the towel scrunched up under the foot.
D. Lift up to full knee extension. Rest. Start again.
Strength
The athlete will initially load throughout the foot with the foot impartial. Exercises such as split squat, high- foot leg press and posterior string movements such as deadlifts and stand pulls may start in the weight bearing phase. Exercises requiring more ankle dorsiflexion and so midfoot pronation will be delayed for a couple of weeks until strength and confidence improve (traditional one-leg squats, deadlifts and leg press).
Rehabilitation
The graded progressions for your athlete have been well summarized by Lorenz and Beauchamp (2013). The progression is a staged progression to gradually regain strength and confidence from landing and push-off positions. If the stage is pain free, the progressions could be made, the athlete could do selection and without compensations to the movement.
1. Bilateral heel raises
2. Heel raise,�single-leg eccentric lower
3. Single leg-heel raise from standing
4. Bilateral leaning heel raises
5.�Bilateral leaning heel raises, single leg�eccentric lower
6. Single-leg leaning heel raises
7. Single-leg triple extension heel raises
8. Mini-tramp low Impact exercises
A. Bilateral jumps in position
B. turns in place (two legs).
C. turns in place (two legs).
D. Jog in place
E. Three hops uninvolved, one hop involved
F. Two hops uninvolved, two hops involved
G. One hop uninvolved three hops involved
9. Agility ladder
A. Different frontal transverse plane designs
B. Hopscotch to involved negative (two to one)
10. Single-leg A/P jumps in place
11. Single leg M/L jumps in place
12. Single leg transverse jumps in position
13. Single leg hops in agility ladder
Return To Running
The choice as to when to remove the hardware will influences the choice. As a general rule, when the screws and wires are eliminated, the athlete will be permitted to attend and walk gym sessions to the elimination but running will probably be delayed.
The athlete is encouraged to walk a treadmill using a incline to promote the push. This can start at 12 weeks . The athlete may quickly advance into backward and forward running on grass and it’s expected they are doing so by week 14 depending on when the hardware was taken away. As they progress through running they could slowly begin to construct speed they reach sprint speed.
Gentle off-line running drills such as weaving, easy bypassing, stepping and caricoca drills would normally be started in around 16 weeks post-op and progressed into tougher single-leg and hard-cutting plyometrics as pain allowed. It would be expected that by 20 weeks post-op, the foot has sufficient strength, range of movement and confidence to start team- based ability function. Prior to this, the athlete can experience some frequent field hop tests like tests and single-leg triple jump to assess differences in abilities.
Functional Tests
A evaluation that is practical sports-specific is a test or field test that aims to mimic the movements. The use of practical tests aims to recognize imbalances and will boost confidence in both patient and the clinician the injured patient can return to play. It is effectively a way of reducing the hazard. The evaluation ought to be an objective, measurable and quantifiable test that includes a component of:
Strength
Agility
Power
Balance Neuromuscular status.
The aspects can be incorporated into practical tests such as agility and jumps/ movement evaluations.
The hop tests comprise:
1. Single jump
2. Triple hops
3. Crossover jump
4. 6m timed jump.
Single limb evaluations are necessary as study proves that dual limb and modified double limb tests don’t demonstrate any differences between groups since the uninvolved limb can mask deficits of the thoracic (Myer et al 2011). Single-leg hopping evaluations are sensitive enough to discover asymmetry, and specifically the crossover hop test at six months post-op is the most sensitive of these tests at predicting future function of the knee along with the 6m timed test is the most vulnerable and sensitive of under normal function at six months . (Logerstedt et al 2012).
Therefore isolated single-limb performance tests may provide a critical element to field-based operational performance testing to identify deficits in reduced limb performance, including deficits in force attenuation functional power and postural stability. The capability to maintain isolated single limb electricity is significant in sports that require significant control in stepping edge and cutting manoeuvres. This may require and ability to regenerate and divert and then to absorb force on one limb the motion.
Conclusion
Injuries are uncommon in athletes on account of the severe consequences they could have on athletic role, the sports medicine specialist has to be well versed in evaluation and initial management. They can be challenging injuries manage and to diagnose for the clinician.
Stable Lisfranc injuries with no instability can be handled conservatively stage 2 and 3 accidents involving diastasis of their second and first metatarsals requires consideration. This can be done usually using the open reduction and fixation with screws, K cables and/or plates
Rehabilitation after surgery will take no less than 12-16 weeks it’s typical for the return to sport to take in contact sport athletes. Successful return to competition time frames extend to the 20-24 week stage post-surgery and rehab will involve reduction of the entire limb kinetic chain but also not only the foot muscles.

Chiropractor, Dr. Alexander Jimenez summarizes some fascinating injury stories in the combat game…
I was recently on a holiday in Koh Lanta in Thailand and throughout my holiday I visited a Muay Thai training gym for two reasons. Firstly, as I’ve had a fascination with the sport for some time having formerly handled some injuries in some fighters in Australia it was to have a private Muay Thai training session with a few of the boxers. I was that I could use as material. I clarified the purpose of my visit and approached the head coach and discover a few of the interesting injury stories they’d out and he was pleased for me to talk to a few fighters. The following are just two case studies from this fact-finding mission.
The Biker’s Elbow
The initial fighter was a seeing K1 fighter out of Holland who spends six weeks a year in Thailand. He had been a fit and healthy 25-year-old man with a history of prior knee and back injuries; nonetheless, his complaint at this stage was pain on the inside of the right elbow that made grappling through fighting and also lifting weights at the gym hard.
The pain had started only a few days to his recent trip to Thailand and had been present for about five days. It had been focused around the medial epicondyle of the elbow. Any powerful gripping moves whilst flexing the elbow was shown to be debilitating. It had been affecting his coaching as some other work that was grappling was too painful and he was unable to perform any type gym movements such as chin ups and rowing motions. All pushing type movements were asymptomatic.
He whined no preceding elbow pain and refused any trauma to the elbow such as a arm lock-type situation or a hyperextension type injury during training or fighting.
He had been tender to palpate the source of the wrist flexor muscles which start on the elbow along, as well as any forceful wrist extension was uneasy. His elbow felt secure and using a stress test. Strong grip of the hands was painless until he was put to a position of wrist extension that is complete.
With no history of injury and without any changes to his coaching regimen I quizzed him. We exercised that whilst in Thailand he traveled on a scooter — a pastime for thieves to tackle when. He’d spent plenty of time around the sightseeing on the bicycle when he came.
The type of scooter he used was a automatic without equipment shifting the accelerator is on the right side of the bars. The reasoning was because of the continuous wrist extension used to accelerate the scooter at a pronated position, the wrist flexor muscles were put in a position of stretch with constant tension due to the co-contraction of this wrist flexor/extensor group required to do this particular movement. Coupled with this was that the vibration that is constant on the bicycle caused by the movement of the scooter in addition to the frequent pot holes and undulating road typical of Thai roads. The diagnosis was an inflammatory response in the wrist flexor origin.
I made the following suggestions:
1. Regularly extend by putting the hand flat on a table with the wrist turned to supination, the wrist flexors. He was to hold this for 30-second efforts.
2. Soft tissue massage to the wrist flexor muscle group, something he could do in Thailand using the massages on offer.
3. Moderate outrageous wrist flexor exercise working with a 5kg dumbbell using the forearm put on a desk (palm upward) and also to slowly lower the weight into wrist extension and use the flip side to help the concentric lifting. He was to do this
4. Change the hand place on the accelerator. It was suggested he can do three distinct things to achieve this. Primarily he can flare the elbow out broad whilst riding to decrease the amount. He up to this point kept the elbow close in to the body to perform this. Secondly he could occasionally hold the accelerator handle on the end so that he could keep his forearm supination position as this requires radial deviation to quicken the bike. Finally, on stretches of street I invited him undo the grip so he utilized wrist flexion to accelerate the bicycle and to actually supinate his forearm.
5. Rub some topical gel.
Two weeks later, I saw him and he maintained that the elbow pain had entirely subsided.
The Buzzing Thigh
A 30-year-old Thai local fighter had whined a six- month history of a ‘buzzing’ kind pain on the outside of the thigh and in the calf that was ideal region. It’d started after he obtained a hard kick to the back of his right hip. The kick was so strong that he lost function of his right leg at the time and needed a sensation down the thigh into the foot and calf. As this occurred in training, he rested on the leg and stopped and used the Thai concoction of heat and ointments to manage this harm. He returned to coaching a couple of days later and had been involved in a couple of fights after. He felt he had been still practical, but still felt a buzzing sensation every time. He claimed that he managed to perform everything and even blows to the thigh and hip were no longer painful than normal.
On examination he had movement in both hips his internal rotation when lying prone was decreased compared to another side. He was able to squat and perform a single leg pain free. All knee motions and ligament testing demonstrated unremarkable.
What was painful was a slump test on the ideal side and this reproduced the proper- sided throat sensations he experienced with kicking. The pain was made worse with dorsiflexion of the ankle whilst at a slump position.
It was concluded that when he had sustained the blow to the posterior hip, he had bruised the subsequent hematoma and the right piriformis muscle had created fibrosis around the sciatic nerve. Each time he had to stretch into full hip flexion with the knee extended and the foot dorsiflexed to complete a roundhouse kick, he had been effectively stretching the nerve against the port made by the scarring and fibrosis around the guts by the preceding injury to the soft tissues. This would be sufficient to give him a neuropathic-type pain down the leg across the course of the nerve and in the superficial peroneal nerve.
I explained that the way to remove this was to frequently ‘extend’ or move the guts from the vents to try to release the nerve out of any fibrosis. I showed him how to run his own gentle nerve mobilizations as a slide and slide method (neurological wracking) and also how to hold the place on stretch to make a sustained elongation.
He did so sitting on the conclusion of the fighting ring at a full slump position (neck flexed, spine arched into flexion) and he had been to straighten the ideal knee with the foot dorsiflexed until he felt a gentle uncomfortable tug onto the guts (felt like a buzzing down the ideal leg). This was to be achieved to this point of discomfort but not pain. I explained that if he overdid motion and this stretch he could make the issue worse, so I invited him to underdo this and not over do this. He had been to spend five minutes after a warm-up finishing a string of knee extension and release the stretch. After a pause continue this on/off movement for five minutes per day and he was to stretch again.
I didn’t figure out how this solved as this movement would take a few weeks to make a noticeable shiftI can expect that he would have discovered a relief from his signs at some stage in the future.
Chiropractor, Dr. Alexander Jimenez looks at the way this common injury shows itself.
Introduction
Iliotibial band syndrome (ITBS) between the knee is frequently diagnosed in sport injury clinics. ITBS presents having an incidence rate of around 22% in most lower extremity running-related injuries (1) also has been said to be the second most common complaint amongst distance runners (2). ITBS has been given the expression ‘runner’s knee’.
Trainers like endurance runners who perform flexion and extension combined with loading are subjected to this illness. ITBS presents during the first two or three miles in running with no mechanism of injury, which can make identifying the cause more interesting. With plenty of factors having been considered within the literature, changes are often purported to be a cause of ITBS. But some biomechanical factors have been researched and have been found to have little or no effect in the start of ITBS. Therefore this text’s point would be to examine the biomechanical changes which may induce an individual to the beginning of ITBS. The research published reviewed is largely based on a current systematic review that was published in Physical Therapy in Sport in 2014 (3).
Anatomy & Function
The iliotibial band (ITB) encapsulates the tensor fascia latae (TFL) presenting with both deep and superficial fibre attachments at the pelvis (4). In addition to attaching to the TFL, approximately three-quarters of the gluteus maximus tendon also conjoins with the ITB (4). The ITB courses along the lateral aspect of the hip and passes the greater trochanter. The ITB maintains an attachment on the posterior ridge of the femur whilst attaching itself to the fascia. The ITB has a fixed attachment at the lateral femoral condyle where it then divides into three segments with the first being the lateral patella (3). The remaining two segments cross the knee joint to insert at the head of fibula and most distally at the infrapatellar tubercle also known as Gerdy’s tubercle on the tibia (3). Figure 1 illustrates the location of the ITB.
The ITB passively functions to resist hip adduction, hip internal rotation and internal rotation of the knee in accordance with its attachments at the pelvis, femur and tibia(3). The gluteus maximus functions, through its attachment, to increase stability through the hip and knee complex by increasing the tension of the ITB(4). It is possible to see, based on its attachments at both the knee and hip, how changes could bring about the onset of ITBS.
Studies have proposed that as the knee flexes and extends the ITB ‘slides or flicks’ over the lateral femoral condyle of the knee causing an irritation beneath. This notion was debated by Falvey and colleagues (5), who stated that it was highly unlikely that the ITB would flick or slide over the bone during knee flexion due to it not being a loose structure. But the authors did agree that the impact of compression on the richly innervated fat pad was pain’s cause but by strain of the ITB where pain presents crossing the lateral femoral condyle. Strain rate and strain magnitude were measured in a prospective study involving female runners (6). The results indicated that frequency of strain of the ITB at the lateral femoral condyle was greater that the strain magnitude. This implies that a runner might have the ability to run for a short period but then incur lateral knee pain because of the strain to the ITB.
MRI scans have ascertained the knee flexion angle of 30� elicited the greatest compression of the ITB at the point of heel strike, whereas others have said that maximal compression occurs between 20-30�(2,6). A knee flexion angle at the point of heel strike has been found to be significantly different with 20.6� in ITBS patients compared to 15.3� in the control(7). Downhill running produces a greater knee flexion angle at the point of heel strike eliciting a larger strain load to the ITB and therefore this is often a main precursor to ITBS (6). Although an elevated knee flexion angle at the point of heel strike has been considered to contribute to ITBS, it is essential to examine the lower extremity from the frontal and transverse planes too and not solely from the sagittal plane (2).
Rearfoot Eversion
It’s possible to envisage how rear foot eversion could contribute to ITBS causing internal rotation of the tibia resulting at the distal attachment in greater strain of the ITB. In contrast Ferber and colleagues (2) indicated that there was no significant difference in the peak eversion angle of the female subjects, who were previously diagnosed with ITBS but were now symptom free, compared to controls. In a similar study non-significant differences were found between the currently symptomatic ITBS patients and controls for rear foot eversion (8).
Louw & Deary(3) found that ITBS patients sometimes demonstrated decreased eversion angles, accompanied by decreased internal rotation of the knee, at the point of heel strike. Ferber and colleagues (2) noted an increased inversion moment in the ITBS group which was suggested to control and limit the eversion moment. By comparison, currently symptomatic ITBS patients demonstrated a substantial difference compared to a control group with twice the rear foot motion during running (9).
Knee Internal Rotation
Peak internal rotation angle of the knee was found to be significantly greater in the ITBS patients when compared with controls at the point of heel strike (2). This research was supported by other studies who also found a significant effect for increased internal rotation of the knee following a run of moderate intensity to physical exhaustion(7). With excessive rotation comes compression due to increased strain of the ITB at the attachment.
An explanation of increased internal rotation of the knee was attributed to excessive external rotation of the femur perhaps due to shortening of the piriformis, gemellus inferior and superior and the obutrator externus (8). The authors added that excessive rotation at the hip might result from muscular activity of the rotators that were hip being the medius, minimus and the tensor fascia latae. These studies(2,7) were retrospective in design in that they tested healthy runners with a history of ITB pain, whereas(8) was a prospective study of patients with ITBS at the point of testing.
Hip Adduction Angle & Hip Abductor Strength
The hip adduction angle during the stance phase has been suggested to be greater. Ferber and colleagues(2) found that the peak hip adduction angle was significantly greater in the ITBS cohort and stated that with 95% confidence. Increased angle results in increased stress to the ITB and consequently increased compression at the lateral femoral condyle when combined with increased internal rotation of the tibia.
Figure 2 illustrates, when peak hip adduction and internal rotation combine, how this may result in increased the compression of the ITB at the lateral femoral condyle. Louw and Deary(3), however, stated that it remained inconclusive whether the peak hip adduction angle was a substantial element. Additional research is therefore required to support Ferber and colleagues'(2) initial findings as this study was a retrospective study carried out on healthy female runners with a history of ITBS.
Hip Abductor Strength
It’s been proposed that an increased peak hip adduction angle may coincide with hip abductor activity involving the gluteus medius in this group. During the stance phase of gait the gluteus medius functions to keep stability. Research has indicated that during stance the adduction forces can exceed three times an individual’s body weight(3). What’s more, it was stated that these forces were beyond the metabolic capacity of the gluteus medius to main pelvic stability during the stance phase using just this muscle alone(3).
Louw and Deary (3) were not able to identify a heightened hip abductor moment in the ITBS patients with increased peak hip adductor angles and suggested that it was more of an issue of timing as opposed to the size of the hip abductors. Louw and Deary (3) stated that the research is yet to examine trunk and pelvic movements in ITBS patients and it is plausible to suggest that biomechanical changes from higher up the kinetic chain has the potential to be a contributing element in ITBS etiology.
A research study of 24 (14 female, 10 male) patients with ITBS undertook a six-week rehabilitation programme to increase the strength of the hip abductors(10). Following six weeks of hip abductor strengthening to running 22 patients reported being pain-free and had returned. The female patients reported an average hip abductor torque increase of 34.9% and the male patients found 51.4% increase. However this study used a hand held dynamometer to measure isometric strength and therefore Fedricson (10) findings should be viewed with caution.
A more recent study assessed the hip abductor strength of currently symptomatic patients with healthy controls in a fixed position(11). The results indicated that no substantial differences occurred for static and dynamic hip abductor strength between the groups. Further research should look into the EMG and strength of the hip abductors in the role of managing ITBS. Table 1 shows of significance in the some of the variables of the studies used in this text.
Rehabilitation programs, following periods of immobilization and during, should include gluteal exercises to provide stability to the leg that is involved. If active exercises for the gluteal muscles are provided in a manner that is secure and effective then this can influence the period of transition from non weight. It’s prudent based on the research provided to date to develop function although research is lacking in terms of quality and volume as to the biomechanical influences on the etiology of ITBS. This guarantees that once load bearing commences that the leg that is involved has the stability and control that is active to keep the beginning of load of the ITB.
Summary
The recent review published by Louw and Deary(3) indicates that much of the research published within the literature depending on the etiology of ITBS is inconclusive. The level of research is relatively low and is based on retrospective trials. The research does indicate that knee biomechanics and abnormal hip is involved in the occurrence of ITBS. The authors ascertain that muscle strength is involved as is foot biomechanics that are abnormal. It is recommended that future research should measure kinematic movements of the hip and knee during downhill running as this is a complaint of ITBS onset.

In the first part of the 2-part article on femoro-acetabular impingement (FAI), chiropractor, Dr. Alexander Jimenez discussed FAI and how it can lead to insidious onset abdominal pain and damage the hip joint labrum, leading to early arthritic changes. Given that conservative management generally fails in young athletes and needs operation, part two describes the post-operative rehabilitation period required to take an athlete back to full competition.
The post-operative rehabilitation period is highly dependent on the magnitude of pathology and the subsequent procedure; weight-bearing development is consequently variably reported in the literature.
If the labrum is surgically repaired, then protected weight bearing is encouraged to allow the repair site in order to be protected during the early healing phase. Also, avoiding extremes of flexion (beyond 60�) and also internal/external rotation for the initial 4 to 6 weeks is important to safeguard the repaired labrum. Any positions that possibly create an impingement and boost inflammation ought to be prevented. These include:
Deep squatting
Prolonged sitting
Low couch sitting
Lifting off the ground
Pivoting on a fixed foot
These positions are more safely tolerated following the six week post-operative period. But on account of the selection of hip flexion limitations imposed in the initial six months, usual activities of daily living are rather restricted, making yield to work and daily chores challenging if not impossible from the first few weeks following surgery. Therefore, the post- surgical patient does have to make substantial lifestyle changes and they need assistance in the first six weeks following surgery.
Special precautions in certain types of FAI processes. Reshaping of the femoral head- neck junction can weaken the rectal neck so particular care must be taken in this post- operative period. Fracture of the femoral neck is an unlikely but potentially serious complication after a reshaping process. The athlete may be allowed to bear full weight, but crutches are needed to avoid twisting movements during the initial four weeks after surgery. High impact pursuits and high torsion moves should be prevented in the first 3 months, as bone grafting requires around three weeks to attain full structural integrity.
Furthermore, if microfracture of this femoral head is also done for femoral head cartilage defects, then the athlete ought to be restricted to partial weight- bearing for two weeks so as to optimize the premature maturation of the fibrocartilaginous healing response.
Key points
1. Weight bearing status is dependent on the kind of reshaping procedure, whether the labrum was repaired, and also what the surgeon favors
2. Steer clear of hip flexion beyond 60� in the first 4-6 Weeks
3. Avoid extremes of rotation
Post-Surgical Rehab
Rehabilitation protocols provided in the literature have a tendency to be quite generic in their own advice and at best explain broad transitional phases during the rehab process. They usually describe the transition in weight bearing status, the development of gait through walking into jogging, and give general guidelines as to how to and when to progress activity based on a time dependant strategy.
They then progress describing transitions into twisting and affect actions — usually explained as beginning at 3 weeks following surgery — and generally the guidance is that the speed with which the athlete progresses is variable and might need yet another 1 to 3 months to get full return based on the game. Trainers are usually advised that return to sports after surgical correction of FAI can require 4 to 6 weeks. However it’s critical that progression through rehabilitation phases is driven more by subjective and objective measures during the transition phases. This allows the athlete and therapist to track load (type and quantity) and ascertain whether the joint arrangements are able to withstand changes in load securely.
Wahoff et al (2014) have provided some standards which may be utilized to guide the transition from one point to the next(1). They describe their rationale and supply a complete description of all of the cited tests in their printed clinical comment. Essentially, the exit criteria they offer in each phase are as follows;
So as to advance through the six clarified stages, the athlete may undergo extensive physiotherapy, focusing on hip range of movement exercises, manual therapy and trigger point releases, active stretching, potentially deloaded activities like hydrotherapy or Alta G walking/ running and strong hip rotator and gluteal strengthening exercises. Much of this will be ‘controlled’ and led by the wishes of the surgeon as they will provide the framework on if and what happens concerning loading.
But more direct physiotherapy Interventions have been devised to direct the physiotherapist through the rehabilitation protocol. The Takla-O�Donnell Protocol (TOP) is a validated physiotherapy intervention program which may be utilized to induce the arthroscopically handled FAI patient (Bennel et al)(2).)�This protocol is shown in box 2.
Hip Muscle Control
The focus of the rest of this article Will be to summarize some common yet powerful hip strengthening exercises which may be used to progress the hip muscle control throughout the rehabilitation phases.
Regaining hip muscle power, particularly in the heavy hip external rotator group, is imperative from the FAI recovering athlete. Good muscle endurance and strength in those muscle groups will ensure adequate hip joint compression happens with motion to reduce any shearing effect between the head of femur and acetabulum(3). The muscle groups needing focus are (see figure 5):
Posterior fibres Gluteus Medius (PGMed)
Gluteus minimus
Superior and Inferior Gemellus
Internal and External Obturator
Quadratus Femoris
Piriformis
There’s plenty of exercises that can be utilized to fortify the hip joint musculature. The chosen ones below are a sample of some effective exercises that can be used throughout the rehabilitation phases. However, the key requirements of the contained exercises include:
1. Performed in neutral stylish places to no more than 60 degrees hip flexion. This range of movement protects the hip joint from any possibly damaging impingement.
2. Minimal rotation of the hip, letting them be used in most stages of the rehabilitation process.
3. Performed isometrically or utilizing little oscillating concentric/eccentric contractions — to contract and hold to maintain the hip joint compacted and stable. This represents how these muscles work in individual function.
Summary
In many ways. hip joint labral tears, capsule sprains, cartilage and muscle accidents and bony architectural issues like FAI can all lead to debilitating hip pain. FAI is a real concern for the athlete as the existence of a bone abnormality may lead to a painful hip impingement, damage to the acetabular labrum and premature onset degeneration. FAI’s don’t respond to conservative management. If the athlete suffers debilitating pain that affects competition then the options are either to cease competition all together or have the FAI surgically corrected. Once corrected by the surgeon, regaining complete motion and muscle strength and ultimate game related functional skills will require some time. Hip rotator muscle strengthening must shape the foundation of all handling post-surgical FAI issues.

In the first part of this 2-part series, chiropractor, Dr. Alexander Jimenez looked at the likely signs and symptoms of disc Herniation, in addition to the selection standards for micro-discectomy surgery in athletes. In this report he discusses the lengthy rehab period following a micro-discectomy procedure, and provides a plethora of strength based exercises.
Surgeries to ease disc herniation, with or without nerve root compromise, comprise traditional open discectomy, micro-discectomy, percutaneous laser discectomy, percutaneous discectomy and micro- endoscopic discectomy (MED). Other surgical conditions are employed in The literature like herniotomy that’s interchangeable with fragmentectomy or sequestrectomy. The saying ‘herniotomy’ is defined as removal of the herniated disc fragment just, and the ‘standard discectomy’ as elimination of the herniated disc along with its degenerative nucleus in the intervertebral disc space.
When surgery is required, minimizing tissue disruption and strict adherence to an aggressive rehabilitation regimen may expedite an athlete’s return to perform(1), that explains why micro discectomy is a favored surgical procedure for athletes. Micro discectomy procedures entails Removing a small part of the vertebral bone over a nerve, or removing the fragmented disc stuff from under the compressed nerve root.
The surgeon can then enter the spine by removing the ligamentum flavum that insures the nerve roots. The nerve roots can be visualized with functioning eyeglasses or with an operating microscope. The surgeon will then move the nerve to your side and to subsequently remove the disc material from beneath the nerve root.
It’s also sometimes required to eliminate A small portion of the related facet joint to permit access into the nerve root, and additionally to relieve pressure on the nerve root resulting in the facet joint. This procedure is minimally invasive since the joints, muscles and ligaments are left intact, and the process doesn’t interfere with the mechanical construction of the spinal column.
Endoscopic Lumbar Discectomy
Local Doctor performs lumbar discectomy using minimally invasive techniques.�From the El Paso, TX. Spine Center.
Surgical Outcomes
In general, athletes with lumbar disc Herniation have a favorable prognosis with traditional therapy; more than 90 percent of athletes using a disc herniation improve with non-operative treatment. Many demonstrate a response to conservative treatment with increased pain and sciatica within 6 weeks of the initial onset(2). This implies that the requirement to function immediately could be considered hasty.
However, in case of failed Conservative therapy, or together with the pressure of a significant upcoming competition, surgery might be needed in some instances. Even though it involves surgical therapy, micro-discectomy has been reported to have a high success rate — over 90 percent in some studies(3,4). Patients generally have hardly any pain, are able to return to preinjury activity levels, and therefore are subjectively happy with their results.
The achievement rate of micro-discectomy is The following studies have been summarised to underline the success rate of micro-discectomy procedures:
1. In a survey on 342 professional athletes Diagnosed with lumbar disc herniation in sports like hockey, football, basketball and baseball, it was discovered that powerful return to perform occurred 82% of this time, and 81 percent of surgically treated athletes returned for an additional average of 3.3 years(5).
2. From a limb paresis which might be associated with a disc herniation following surgical treatment. If the preoperative paresis was mild then they could anticipate an 84% likelihood of full recovery. Patients with more severe paresis have less chance of recovery (55%)(6).
3. Wang et al (1999) in a study on 14 athletes demanding discectomy processes found that in single degree disc procedures, the return to game was 90%. However when the procedure involved 2 levels enjoyed considerably less favorable results(7).
4. In a study of 137 National Football League players with lumbar disc herniation, surgical treatment of lumbar disc herniation led to a significantly more career and greater return to play rate than those treated non-operatively(8).
5. Schroeder et al (2013) reported 85% RTP rates in 87 hockey players, with no substantial difference in outcomes or rates between the surgical and nonsurgical cohorts(9).
6. A study by Watkins et al (2003) coping with professional and Olympic athletes revealed the acceptable outcomes of micro-discectomy concerning return to play, since elite athletes in general were highly encouraged to return to perform(10). Also, athletes who had single-level micro- discectomy were more likely to come back to their original heights of sports activities than were people who’d two-level micro- discectomies.
7. A study by Anakwenze et al (2010) investigating open discectomy at National Basketball Association participants demonstrated that 75% of patients returned to perform again compared with 88 percent in control subjects who did not undergo the operation(11).
8. A recent review found that conservative therapy, or micro-discectomy, in athletes using lumbar disc herniation seemed to be satisfactory concerning returning the injured athletes into their initial levels of sports activities(12).
These studies conclude that though a Analysis of lumbar disc herniation has career-ending potential, most gamers have the ability to return to play and generate excellent performance-based outcomes, even if surgery is required.
What is also apparent from research Studies is the level of this disc herniation can also determine prognosis after surgery. Athletes shower a greater difference in progress between surgical and non-operative treatment for upper amount herniations (L2-L3 and L3-L4) compared to herniations at the L4-L5 and L5-S1 levels. Patients using the upper level herniations needed less progress with non-operative treatment and marginally better operative outcomes than those with lower degree herniations(13).
There are several possible explanations A range of studies have revealed that low spinal canal cross-sectional area is associated with an increased likelihood of symptomatic disc herniation, and increased intensity of herniation symptoms. The spinal cross-sectional region is the smallest (thus contains a larger possibility of nerve compromise) at the most upper posterior section and the cross-sectional region increases further down to the lower lumbar spine(14).
The location of the disc herniation�(foraminal, posterolateral or central) may also contribute to differences.�In this study, upper lumbar herniations were more likely to happen in the much lateral and foraminal positions than were people in the lower two intervertebral degrees(13).
Post-Surgical Rehab
After micro-discectomy surgery, the Small incision and restricted soft tissue injury makes it possible for the patient to be ambulatory reasonably fast, and they’re usually encouraged to start rehabilitation sooner or later during the 2-6 weeks after surgery.
In a review on the efficacy of busy Rehabilitation in patients following lumbar spine discectomy, it may be reasoned that individuals can safely take part in high or low-intensity supervised or home-based exercises initiated at 4 to 6 weeks following first-time lumbar discectomy(15).
Herbert et al (2010) discovered that with Effective post-surgical rehabilitation plans, there was a key accent on lumbar stabilisation exercises(16). Second, positive trials tended to initiate rehabilitation earlier in the postoperative interval compared to negative trials (about 4 vs 7 weeks).
Outcome Measures
The most widely used result Measure following back injury and/or disc surgery is the Oswestry Disability Questionnaire(17). This questionnaire is reported to have good levels of test-retest reliability, responsiveness, and also a minimum clinically important difference estimated as 6 percent(18) Furthermore, treatment success has been defined as a 50 percent decrease in the Modified Oswestry Disability Questionnaire score(19).
Concerning physical performance measures following back disc or pain operation, a commonly used clinical examination is that the Beiring-Sorensen Back Extension examination (see Figure 1)(20). This test is performed in a prone/horizontal body position with the spine and lower extremity joints at neutral position, arms crossed at the chest, lower extremities and pelvis supported with the top back unsupported against gravity.
Rehabilitation Program
Presented below is a five-stage rehabilitation program. The stages involved in rehabilitation are:
1. Optimize tissue healing — protection and regeneration
2. Early loading and foundation
3. Progressive loading
4. Load buildup
5. Maximum load
This program has been designed to get a field hockey player with had a L5/S1 lumbar spine discectomy. Even though the progressions from one point to the next are driven by the exit standards related to that stage, it might be anticipated that the athlete could progress in post-surgery to ‘fit to compete’ in about 12-13 weeks.
In this phase it’s anticipated that the athlete will remain relatively quiet for 2-3 weeks post surgery. This allows for full tissue recovery to happen, including scar tissue maturation. The athlete is allowed to completely mobilize in full weight-bearing; however care needs to be taken using any flexion and rotation motions and no lifting will be allowed.
The athlete can begin with the physiotherapist with the objective to manage any gluteal and lumbar muscle trigger points and start�nerve mobilization techniques that show how to engage the TrA and LM muscles (see Figures 2a and 2b).�If the physiotherapist has access to your muscle stimulator (Compex), then this can be utilized in atrophy manner on the lumbar spine multifidus and erector spinae. The key criteria to exit this early phase are curable walking as well as also an Oswestry Disability Score of 41-60%.
Early Loading & Foundation
The primary feature of this phase is that the athlete can start early and low-load strength exercises focusing on muscle activation in a neutral spine position, along with a progressive selection of motion program to improve lumbar spine flexion, extension and rotation. In this stage that the physiotherapist will guide the athlete through safe and gentle stretches to your hip quadrant muscles like the hip flexors, gluteals, hamstrings and adductors. The athlete also lasts gentle neuro-mobilization exercises to advance the freedom of the sciatic nerve — an issue in this condition as neurological tethering is a chance as a result of scar tissue formation caused by the surgical procedure.
The athlete can also be encouraged to start hydrotherapy in the form of walking in water (waist high) along with swimming fitnesscenter. In addition, he/she must start a string of low degree muscle activation drills in this stage (see Figure 3) that can be performed every day. This exercise teaches the athlete to hip flex (fashionable hinge) whilst maintaining a neutral spine. The neutral spine is maintained by using a light broomstick aligned with the back with the touch points being the occiput, the 6th thoracic vertebrae (T6) and the posterior sacrum.
Progressive Loading
In this phase the athlete continues with a variety of movement progression along with the physiotherapist progresses manual therapy to the pelvis and lumbar spine. Neuro-mobilization techniques can also be progressed. The significant change in this phase is that the progression of load on many of the strength and muscle control exercises.�Two exercises here are the �standing twisties� and the �crook lying pelvic rotation� exercise (Figures 4 and 5).�These movements are the introductory spinning based movements. The primary progression about fitness drills is the athlete can begin pool running drills.
Load Accumulation
This is the stage where the athlete begins to advance the load in strength-based exercises. Resistance is used in the form of barbell load and band resistance. Three exceptional exercises performed here are the ‘kneeling hip thruster’, ‘deadbug antirotation press’ and also the ‘quadruped walkout’ (Figures 6-8 — explained in detail in the online database of exercises).
The athlete also begins running drills at this phase and it might be expected that as well as building running Amount, the athlete should progress over four weeks to close to full sprint speeds. This is also the stage whereby they would initiate mild to moderate sports special skills drills. Another characteristic of this stage is that the athlete starts the ‘Sorensen test’ exercise (Figure 9) and it will be expected that they can maintain the position for no less than 90 seconds before advancing to the next phase.
Maximum Load
In this final stage, the athlete spreads all core and strength exercises to maximum loads, and they work with the fitness trainer on coming to squat and functional fitness center lift movements. Skill progression can also be advanced alongside sprint and agility drills. The last exit standards prior to advancing to endless strength and training work is they have to keep the ‘Sorensen test’ for 180 seconds and their self documented Oswestry scale ought to be someplace between 0-20%.
Chiropractor, Dr. Alex Jimenez looks at lumbar spine disc herniation. What are the Likely signs and symptoms associated with disc herniation, and what would be the selection criteria for micro-discectomy operation in athletes? Complaint in the young college age athlete and professional athlete, and it’s been estimated that over 30% of athletes complain of back pain at least once in the profession(1).
Lumbar spinal disc herniation is one kind Of lumbar injury that can’t just cause painful low back pain, but can also compress nerve roots and create radicular referral of pain into the lower leg with related sensation changes and muscle contraction. This injury will not only influence the short-term opponent ability of the athlete, but might also reoccur and eventually become persistent possibly causing a career ending injury.
Managing disc herniation from the athlete Usually begins with conservative therapy and if this fails, surgical solutions are considered. But often elite athletes will request a quicker resolution to their symptoms to minimize time away from competitors. Therefore, providing the criteria for lumbar spine surgery are suggested, the conservative period will often be compressed, and surgery will be sought earlier. The favored surgical process for the athlete with a disc herniation is that the lumbar disc micro-discectomy.
Anatomy & Biomechanics
A significant biomechanical role in the spine, allowing for motion between the spinal segments while spreading compressive, shear, and torsional forces(2). These discs include a thick outer ring of fibrous cartilage termed the annulus fibrosis (akin to the onion rings enclosing the center of the onion), which encompasses a more gelatinous core called the nucleus pulposus, which is included within the cartilage end plates inferiorly and superiorly.
The intervertebral disc consists of Cells and substances such as collagen, proteoglycans, and thin fibrochondrocytic tissues, which enable transmission and absorption of forces arising from body weight and muscle activity. To do so, the disc depends mainly on the structural condition of the nucleus pulposus, annulus fibrosis and the vertebra lend plate. If the disc is normal and is functioning optimally, then forces are spread across the disc evenly(3).
But disc degeneration (mobile Degradation, lack of hydration( disc failure) may decrease the capacity of the disc to withstand extrinsic forces, as forces are no longer distributed and spread evenly. Tears and fissures from the annulus can lead, and with adequate external forces, the disc material may herniate. Alternatively, a sizable biomechanical force set on a healthy, ordinary disc may cause extrusion of disc material as a result of crushing failure of this annular fibers — illustrations include a hefty compression type mechanism because of a fall on the tailbone, or strong muscle contraction such as heavy weight lifting(4).
Herniations represent protrusions of Disc material beyond the confines of this annular lining and in the spinal canal (see Figure 1)(5). If the protrusion does not invade the canal or undermine nerve roots then back pain may be the only symptom.
Endoscopic Discectomy 3D Simulation
The pain associated with lumbar Radiculopathy happens due to a mix of nerve root ischemia (due to compression) and inflammation (because of neurochemical inflammatory mediators released from the disc). Throughout a herniation, the nucleus pulposus puts pressure on weakened regions of the annulus, and proceeds through the diminished websites in the annulus in which it ultimately forms a herniation(6 ft). It follows from this that some kind of disc degeneration may exist prior to the disc may really herniated(7).
In contrast to other respiratory Tissues, discs have a inclination to degenerate earlier in life, with some studies demonstrating adolescents presenting signs of degeneration between the ages of 11 to 16(8). With increasing age, there’s further degeneration of the intervertebral discs.
While the disc might be in danger of harm in All fundamental planes of motion, it’s particularly susceptible during repetitive flexion, or hyper-flexion, combined with lateral bending or rotation(10). Traumatic events such as excessive axial compression may also damage the inner structure of the disc. This can occur as a result of a fall or powerful muscular forces developed during tasks such as heavy lifting.
Athletes are generally exposed to high loading conditions. Examples of this include:
1. World-class power lifters, in which the calculated compressive loads on the backbone are involving 18800 Newtons (N) and also 36400N acting in the L3-4 motion segment(11).
2. Elite level football linesmen who have Been proven to present time-related hypertrophy of this disc and changes in vertebrae endplate in response to this repetitive high loading and axial pressure(12).
3. Long distance runners have been Shown to undergo significant strain into the intervertebral disc, indicated by a reduction in disc height(13).
Herniations could be classified depending on Ultimately, herniations are also identified based on level, with most herniations happening at the L4/5 and L5/S1 intervertebral disc level; these can then in turn affect the L5 and S1 nerve roots resulting in clinical sciatica(15). Upper level herniations are less common, and when they do occur with radiculopathy, they will affect the femoral nerve. Finally, the prevalence of disc injury rises increasingly caudally, with the best numbers at the L5/S1 degrees(16).
Herniation In Athletes
The offending movements implicated in The 20-35 age group are the most common group to herniate a disc, most likely because of the fluid nature of the nucleus pulposis and due to behavior(18). This age group are more likely to participate in sports which need high lots of flexion and spinning or are reckless with their positions and positions during loading.
The sports most at risk of disc herniation are:
Hockey
Wrestling
Soccer
Swimming
Basketball
Golf
Tennis
Weightlifting
Rowing
Throwing events
These are the sports that involve either significant Furthermore, those who take part in more and more severe training regimes seem to be at higher risk of spinal pathologies, as do people involved in sports.
Signs & Symptoms Indicating Discectomy
The efficacy of management programs for lumbar spine disc herniation — in terms of the decision to operate or treat conservatively — will be discussed in greater depth in part 2 of this series. However, the decision to operate within an athlete is generally driven by the motivation and approaching goals the athlete has put themselves. They may in fact favor a comparatively simple micro-discectomy instead of waiting for symptoms to abate through an extended period of rehabilitation.
This conservative period of Management may involve medicine therapy, epidural injections, relative back and back muscle recovery, acupuncture, osteo/chiropractic interventions. On the other hand, the normal presenting symptoms and signs that suggest a substantial disc herniation that will require surgical intervention in the athlete comprise:
Low back pain with pain radiating down one or both legs
Positive straight leg raise test
Radicular pain and neurological signs consistent with the nerve root level affected
Mild weakness of distal muscles such as extensor hallucis longus, peroneals, tibialis anterior and soleus. These would fit with the myotome relevant for the disc level
MRI confirming a disc herniation
Possible bladder and bowel symptoms
Failed conservative rehabilitation
Time span in which to enable conservative rehabilitation to be effective. In the overall population, medical practitioners will most likely prescribe a minimal 6-week traditional period of treatment with an overview at 6 weeks as to whether to expand the rehabilitation a further 6 weeks or to seek a specialist opinion. The expert may then attempt more medically orientated interventions such as epidural injections.
The athlete nevertheless will have these They might be more inclined to experience an epidural very early in the conservative period to assess the effectiveness of this procedure. If no signs of progress are evident in a couple of weeks then they may choose to get an immediate lumbar spine micro- discectomy.
Endoscopic Lumbar Discectomy

Imaging
MRI remains the favored system of Identifying lumbar spine disc herniation, since it’s also very sensitive to detecting nerve root impingements(23). However, abnormal MRI scans can occur in otherwise asymptomatic patients(25); hence, clinical correlation is always essential before any surgical thought. What’s more, patients can present with clinical signs and symptoms which suggest the diagnosis of acute herniated disc, and yet lack evidence of sufficient pathology on MRI to warrant operation.
Therefore it has been proposed that a Volumetric analysis of a herniated disc on MRI may be potentially beneficial in checking the suitability for operation. Several writers have previously mentioned the possible value of volumetric evaluation of herniated disc on MRI as part of their selection criteria for lumbar surgery(26).
In a survey conducted in Michigan State University, it was found that the size and positioning of the herniated disc determined that the likelihood for operation with what researchers called ‘types 2-B’ and ‘types 2-AB’ being the most likely candidates for surgery(27).
The MRI protocol to your lumbar spine consists of (see Figure 2)

2. Sagittal fast spin echo proton density sequence
3. Sagittal fast spin echo inversion recovery sequence
4.Axial spin echo T1- weighted sequence
Summary
Disc herniations are not a common Complaint in athletes, but they do happen in sports which involve high loads or repetitive flexion and rotation movements. Sufferers of a disc herniation will normally feel focused low-back pain, maybe with referral in the lower limb with associated neurological symptoms if the nerve root was compressed.
Managing a disc herniation within an General population as frequently the risk of a Protracted failed rehabilitation period is Bypassed for the protected and low risk Micro-discectomy procedure. In the Discuss the exact surgical alternatives involved Observing a lumbar spine micro-discectomy.

So as to advance through the six clarified stages, the athlete may undergo extensive physiotherapy, focusing on hip range of movement exercises, manual therapy and trigger point releases, active stretching, potentially deloaded activities like hydrotherapy or Alta G walking/ running and strong hip rotator and gluteal strengthening exercises. Much of this will be ‘controlled’ and led by the wishes of the surgeon as they will provide the framework on if and what happens concerning loading.
Hip Muscle Control
Summary
In this phase it’s anticipated that the athlete will remain relatively quiet for 2-3 weeks post surgery. This allows for full tissue recovery to happen, including scar tissue maturation. The athlete is allowed to completely mobilize in full weight-bearing; however care needs to be taken using any flexion and rotation motions and no lifting will be allowed.
Early Loading & Foundation
The primary feature of this phase is that the athlete can start early and low-load strength exercises focusing on muscle activation in a neutral spine position, along with a progressive selection of motion program to improve lumbar spine flexion, extension and rotation. In this stage that the physiotherapist will guide the athlete through safe and gentle stretches to your hip quadrant muscles like the hip flexors, gluteals, hamstrings and adductors. The athlete also lasts gentle neuro-mobilization exercises to advance the freedom of the sciatic nerve — an issue in this condition as neurological tethering is a chance as a result of scar tissue formation caused by the surgical procedure.
