For many individuals, getting on the floor to do crunches or other exercises can be difficult due to medical conditions, age, and injuries. Can engaging in chair abdominal exercises at home, work, or anywhere a chair is available help strengthen the upper, lower, and oblique abdominal muscles?
Chair Abdominal Exercises
Chair abdominal exercises are essential for strengthening the core, maintaining healthy flexibility, mobility, posture, and injury prevention. Incorporating abdominal exercise into one’s day can be easy, regardless of schedule or fitness level. Various exercises are designed to be performed while seated, making them accessible to everyone, including those with mobility issues or new to exercise.
Benefits
Building and maintaining a solid core is essential for overall health, posture, and daily activities, especially as the body ages. A strong core maintains body balance and stability, prevents falls, protects individuals from back pain, and makes lifting, bending, and walking easier. It allows individuals to stay independent and active. The abdominal muscles are one part of the core, which includes muscles in the back, glutes, pelvic floor, and diaphragm. These are important for keeping the body upright and stable, protecting the spine and organs, and assisting with movements between the ribcage and pelvis. Adding abdominal exercise workouts to a fitness routine is one way to improve overall core strength and stability. Chair-based exercises are convenient and accessible as individuals don’t need specialized machines or equipment, just a sturdy chair and some space. (Frizziero A. et al., 2021)
Chair Workout
Chair abdominal exercises are ideal gentle exercises for older individuals who need to increase their strength and mobility. Because chairs provide stability and safety, these exercises focus on seated movements and are intended for those with limited mobility. Chair abdominal exercises can be adapted and modified to individual preferences and needs, preparing the body for more advanced standing exercises. They improve the ability to perform daily tasks and increase joint mobility, muscle strength, and coordination. To prevent injuries, each exercise session should begin with a warm-up and end with a cool-down.
A warm-up could be gentle seated marches, shoulder rolls, and deep breathing exercises.
A cool-down can include seated stretches, focusing on the back, neck, and legs to help the body recover and prevent stiffness.
It is recommended that patients talk to a healthcare provider first if they have limited mobility or chronic health issues. Here are some sample exercises.
Sitting Knee Lifts
Sit on the edge of the chair with your back straight.
Lift your knees toward your chest, engaging the upper abs.
Lower them slowly back down.
Repeat for 10 to 15 reps.
Beginners lift one knee at a time.
Lower it and repeat with the other leg.
Sitting Crunches
Sit on the edge of the chair.
Lean back slightly.
Place hands behind your head.
Crunch forward, bringing the chest toward your knees.
Return to the starting position.
Repeat for 10 to 15 reps.
Beginners can sit more on the chair and hold the seat for stability.
Reduce the range of motion when crunching the chest toward the knees.
Sitting Leg Lifts
Sit on the edge of the chair with the back straight.
Extend your legs in front of you and lift them together, engaging the lower abdominals.
Lower them back down slowly.
Repeat for 10 to 15 repetitions.
Beginners sit back on the chair and grip the sides.
Lift one leg and hold for a count before lowering.
Switch legs.
Sitting Scissor Kicks
Sit on the edge of the chair and lean back slightly.
Extend your legs in front.
Alternate lifting each leg up and down in a scissor motion.
Perform for 30 seconds to one minute.
Beginners tap one heel on the floor between lifts to reduce abdominal tension.
Sitting Side Crunches
Sit on the edge of the chair with the back straight.
Lift one knee toward the chest while bringing the opposite elbow toward the knee, engaging the obliques.
Alternate for 10 to 15 reps per side.
Beginners, keep your feet flat on the floor with your hands behind your head.
Gently bend to the side, return to the center, and bend to the other side.
Sitting Bicycle Crunches
Sit on the edge of the chair and lean back slightly.
Lift the feet off the ground.
Alternate bringing each knee toward the opposite elbow in a pedaling motion.
Perform for 30 seconds to one minute.
For beginners, keep the heel gently on the ground while you crunch on the opposite side.
For a challenge, slow the motion and hold each twist a few seconds longer to create more tension. (Krzysztofik M. et al., 2019)
Progress
For beginners, start with the easier versions and perform fewer repetitions and shorter durations if needed. Focus on maintaining proper posture and form. As the body gets stronger, increase the number of repetitions or extend the duration of each exercise. Once comfortable, try more challenging chair exercises. Chair abdominal exercises are a simple, effective way to strengthen the core, improve posture, and support overall health. Regularly doing these exercises as part of a well-rounded routine can build a solid core without special equipment. Remember to listen to the body and progress at your own pace to more challenging variations over time to keep building strength.

The iliacus muscle is a triangle-shaped muscle in the pelvic bone that flexes and rotates the thigh bone. It works with the other muscles in the hip and thigh to help bend, run, walk, sit, and maintain correct posture. Injuries and common medical conditions can affect its function, causing pain and stiffness. Can physical therapy help?
The Iliacus Muscle
The iliacus is one of the body’s most important hip flexor muscles. The iliacus and surrounding muscles work together to produce the stability and range of motion required for bending, dancing, sitting, and walking.
Anatomy
The iliacus muscle is part of a complex muscle system in the hip and pelvis. Two iliacus muscles on each side of the pelvic bone enable the thigh to flex and rotate. They are innervated by the femoral nerve, which provides movement and sensation to the lower limbs. (Bordoni B. and Varacallo M. 2023) The iliacus muscle sits on the wing-shaped ilium and fits into the curved surface of the ilium, called the iliac fossa. The top of the muscle is attached to the upper wings of the ilium or iliac crest. It extends past the hip joint, which connects to the upper thigh bone/femur at the lesser trochanter protrusion. The iliacus is part of a major trio of muscles called the iliopsoas, including the major psoas and minor psoas muscles. These muscles are also attached to the upper femur but extend upward, connecting to the lumbar/lower spine at several attachment points. The iliopsoas also interact with the quadratus lumborum muscle, the deepest muscle of the lower back that starts at the iliac crest and attaches to the lumbar spine at several points. The quadratus lumborum enables flexion and elevation of the spine, while the iliopsoas enable the flexion and rotation of the hip and thigh.
Functions
The iliacus muscle has many functions that include: (Physiopedia, 2024)
Flexing and rotating the femur.
Helps maintain proper body posture while standing and sitting.
Produces hip movement that enables walking, running, and climbing stairs.
Provides hip flexion – bringing the knee to the chest.
Enables the forward tilt of the pelvis and side-bending.
Conditions
Several conditions can affect the iliacus muscle, specifically from under and/or overuse injuries. These conditions, collectively known as Iliopsoas syndrome, are typically the result of overuse/repetitive strain or injuries. These include:
Iliopsoas tendinopathy – which affects tendons.
Iliopsoas bursitis – which affects cushioning sacs known as bursae.
Iliopsoas syndrome can affect anyone but is common in:
Individuals and athletes who repeatedly use movements that flex the hips.
Track-and-field athletes
Gymnasts
Dancers
Iliopsoas Bursitis
This is the inflammation of the cushioning sac or bursa under the iliacus muscle, which helps the muscle slide over the pelvic bone. Symptoms can range from mild discomfort to pain that radiates through parts of the leg and hips. Runners, skiers, and swimmers are commonly affected, and individuals who regularly have tight hips and individuals with different forms of arthritis can also be affected. Early treatment can prevent the symptoms from worsening. Mild cases can be treated with self-care and stretching to help relieve tightness, rest, ice application, and over-the-counter nonsteroidal anti-inflammatory drugs. In severe cases, treatment options that may be recommended include: (Physiopedia, 2024)
Physical therapy
Assistant walking devices to relieve pressure – for example, a cane.
Corticosteroid steroid injections
Prescription anti-inflammatory medications
Iliopsoas Tendinopathy
Another condition affecting the iliacus muscles is iliopsoas tendinopathy, sometimes called snapping hip syndrome, because individuals can hear an audible snapping sound (Davenport KL. 2019). The condition is often experienced by dancers who repeatedly flex and hyperextend their hips and can result in hip and groin pain that gets worse with kicking or rotation. Treatment of iliopsoas tendinopathy can include:
Retraining muscle imbalances with strengthening and stretching exercises.
If these fail to provide relief, corticosteroid injections may be used. A saline hydro dissection can relieve stress around the tendon by injecting fluids that cushion and release trapped tissues.
Tendon release surgery may be recommended when all other options have failed. The surgical release involves severing the tendon to reduce pain and improve the range of motion.
Rehabilitation
Core muscle strengthening is essential to the rehabilitation of iliacus muscle injuries. The iliopsoas is an integral component of the core group and can benefit from stretching and strengthening exercises (Yogateket, 2019)
Lunge stretches
Straight leg raises
Knee-to-chest stretches
Standing hip flexion with resistance bands
Certain yoga poses can also help and include variations on the bridge pose that encourage hip flexion. (Yoga International, 2024)
Injury Medical Chiropractic and Functional Medicine Clinic
Iliopsoas pain is often felt at the front of the hips, thigh, mid-back, and lower back. Chiropractic care can help with iliacus muscle injuries through:
Evaluation
A chiropractor can evaluate the condition and determine if the iliacus muscle is causing pain.
Treatment plan
A chiropractor can create a personalized treatment plan that may include exercise instructions, manipulation, and other therapies.
Rehabilitation
A chiropractor can create a rehabilitation program to expedite healing.

Can correcting body misalignments and the elements of unhealthy posture help achieve a healthy posture?
Healthy Posture
Maintaining a healthy posture is more important than ever, as individuals from all walks of life realize how practicing awkward and unhealthy postures can wreak havoc on their bodies and quality of life. Unhealthy postures include rounding the upper and lower back, slouching, and forward head posture. Over time, these postures make daily activities more difficult or painful. Mobility, stability, and strengthening exercises can address unhealthy posture problems and issues, along with practicing correct sitting, standing, and resting postural habits to reinforce proper alignment daily. A chiropractic and physical therapy team can treat and train individuals to restore correct and healthy posture.
Body Alignment
Ideal posture involves correct body alignment or how the structural parts, such as the head, trunk, hips, knees, etc., relate to an individual’s form. Whether standing, sitting, lying down, or moving, body parts need to be balanced in relationship to each other to avoid unnecessary stress on the spine and musculoskeletal system. (Bone Health & Osteoporosis Foundation, 2024)
Posture Types
Posture is considered static when sitting or standing still and dynamic when moving. Both are categorized as active postures as they require the activation of stabilizing muscles to deal with gravity and maintain alignment. Lying down and remaining still is considered an inactive posture, as muscle involvement is minimal. However, both have the potential to be healthy or unhealthy.
Proper Body Alignment
An easy way to check proper alignment while standing is to stand against a wall with the base of the head, shoulder blades, and buttocks flush against the wall, with enough space for a hand wide enough to slide in between the wall and the small of the back. This exercise correctly lines up the head, shoulders, and hips to reduce or eliminate undue stress on the spine. Body balance is the foundation for active and inactive postures concerning workstations, industrial ergonomics, daily activities, and sports. (Mayo Clinic, 2023) Healthy alignment is a standard position in which all body joints are centered and balanced and the most mechanically efficient position for static or dynamic activities. Biomechanical efficiency (the ability to use the body’s muscles and joints to perform movements while minimizing energy use and maximizing output) enables the muscles surrounding the joints to work in balance and efficiently activate, which, in turn, helps reduce strain, tension, and injury. Balanced muscles also conserve energy, leading to better daily stamina.
Development of Imbalances
Individuals develop position and movement habits in joint positioning that have led to imbalanced muscles. When this is the case, some muscles can be chronically stretched, and others become chronically tight, all to hold the body up or move around, which can lead to postural conditions like upper crossed (Physiopedia, 2024) or lower crossed syndrome (Physiopedia, 2024) which often leads to pain and/or mobility issues.
Posture Assessment
The recommended way to determine if one’s posture is healthy or poor is by conducting a posture assessment. The examination looks at joint positions and gathers visual information about the planes into which parts of each joint move and the axes around which those movements occur (Singla D. and Veqar Z., 2014) (Debra Coglianese et al., 2006). In a posture assessment, body alignment is compared with the ideal standard, a plumb line, usually a string with a small weight attached to the bottom to help maintain straightness. The other end of the string is affixed to the ceiling to be used as an accurate reference for correct alignment. (Singla D. and Veqar Z. 2014) During a posture assessment, the patient stands next to the plumb line while the doctor or therapist compares the relative positions of the following areas:
Ears
Shoulder joint
Spine
Hip joint
Knee joint
Ankle joint
Feet
Any areas that don’t match the reference can indicate misalignments in one or several regions.
Making Corrections
Chiropractic care can help correct unhealthy posture by realigning the spine and strengthening the musculoskeletal system:
Spinal Adjustments
Chiropractors use their hands or instruments to apply controlled force to the spine to realign the vertebrae. This can help relieve pressure on muscles, ligaments, and nerves, which can improve posture.
Corrective Exercises
Chiropractors can create custom exercises to strengthen postural muscles and maintain proper alignment.
Massage Therapy
Chiropractors can use massage therapy to work on strained ligaments and soft tissue.
Guidance and Training
Chiropractors can teach patients how to move to encourage a neutral spine and provide strategies for maintaining healthy posture.
A posture corrector or brace can also help teach and engage the correct muscles to achieve proper alignment. However, it should not be relied on long-term because promoting and activating one’s stabilizing muscles is important rather than relying on a brace for prolonged periods.

An axillary nerve injury can cause pain, weakness, and shoulder mobility loss. Can physical therapy help restore and maintain shoulder joint flexibility?
Axillary Nerve
The axillary nerve, or the circumflex nerve, is a peripheral nerve that runs through the shoulder and supports movement and sensation in the upper limbs. It originates in the neck at the brachial plexus, a network of nerves that extends from the neck and upper torso to the shoulders and arms. Its primary purpose is to supply nerve function to the shoulder joint and three muscles in the arm and also innervates some skin in the region.
Anatomy
Except for the cranial nerves, all the body’s nerves branch off from the spinal cord, emerge from between vertebrae and continue to branch off as they travel to various muscles and other structures. The axillary nerve is named after the axilla, the medical name for the armpit. Individuals have two, one on each side. After leaving the spinal column, the axillary nerve runs behind the axillary artery and continues to the shoulder blade’s lower edge of the subscapularis muscle. It winds back and travels down the arm along the posterior humeral circumflex artery, which then passes through the quadrangular space (a small area of the shoulder blade just above the armpit where there is a gap in the muscles that allows nerves and blood vessels to pass through to the arm before it divides into terminal branches, which are:
Anterior Division
Supplies motor innervation to the deltoid’s anterior and middle heads, allowing the arm to abduct or move away from the body.
It winds around the neck of the humerus/funny bone, goes beneath the deltoid muscle, and then connects to the forward edge of the deltoid.
A few small cutaneous branches serve the skin in that area.
Posterior Division
Innervates the teres minor muscles and the lower part of the deltoid.
It enters the deep fascia and becomes the superior lateral cutaneous nerve.
It then wraps around the lower edge of the deltoid, connects to the skin over the lower two-thirds of the muscle, and covers the long head of the triceps brachii.
Articular Branch
Comes from the trunk of the axillary nerve and enters the glenohumeral joint, which is in the shoulder, below the subscapularis muscle.
Anatomical Variations
In a case report, healthcare providers noted an incidence of the nerve branching directly off the upper trunk of the brachial plexus rather than the posterior cord. (Subasinghe S. K. and Goonewardene S. 2016) In this case, it innervated the subscapularis muscle, latissimus dorsi, and the deltoid and teres minor muscles and also had a communicating branch to the posterior cord. Another case documented multiple abnormalities in the course of the axillary nerve in an individual with pain and severely limited shoulder mobility. (Pizzo R. A. et al., 2019) During reverse shoulder arthroplasty, the surgeon discovered that the axillary nerve ran beside the coracoid process instead of underneath and stayed close to the subscapularis muscle instead of traveling through the quadrangular space. The case noted earlier reports of axillary nerves not running through the quadrangular space. In those cases, the nerve pierced the subscapularis muscle or split into branches before reaching the quadrangular space.
Function
The axillary nerve functions as a motor nerve that controls movement and a sensory nerve that controls sensations like touch or temperature.
Motor
As a motor nerve, the axillary nerve innervates three muscles in the arm and includes:
Deltoid
Allows flexing of the shoulder joint and rotating the shoulder inward.
Long Head of the Triceps
It runs down the back of the outer arm, allowing straightening, pulling the upper arm toward the body, or extending it backward.
The radial nerve can also innervate this muscle.
Teres Minor
One of the rotator cuff muscles starts outside the shoulder and runs diagonally along the bottom edge of the shoulder blade.
It works with other muscles to allow for the external rotation of the shoulder joint.
Sensory
In its sensory role, the nerve carries information to the brain from the following:
Glenohumeral joint or the ball-and-socket joint in the shoulder.
The skin on the lower two-thirds of the deltoid muscle through the superior lateral cutaneous branch.
Injuries and Conditions
Problems with the axillary nerve can be caused by injuries anywhere along the arm and shoulder and by disease. Common injuries include:
Dislocations
Of the shoulder joint, which can cause axillary nerve palsy.
Fracture
Of the surgical neck of the humerus.
Compression
This stems from walking with crutches, also known as crutch palsy.
Direct Trauma
This can be from an impact sports, work, automobile accident, collision, or laceration.
Added Pressure
This can be from wearing a cast or splint.
Surgical Accidental Injury
An injury or damage can come from shoulder surgery, especially arthroscopic surgery on the inferior glenoid and capsule.
Quadrangular Space Syndrome
This is where the axillary nerve is compressed where it passes through that space, which is most common in athletes who perform frequent overhead motions)
Nerve Root Damage
Between the fifth and sixth cervical vertebrae, where the nerve emerges from the spinal cord, which can be caused by traction, compression, spinal disc prolapse, or a bulging disc.
Systemic Neurological Disorders
Example – multiple sclerosis
Erb’s Palsy
A condition often is the result of a birth injury called shoulder dystocia, in which a baby’s shoulder/s becomes stuck during childbirth.
Axillary Nerve Palsy
Damage can result in a type of peripheral neuropathy that can cause weakness in the deltoid and teres minor muscles.
This can result in losing the ability to lift the arm away from the body and weakness in various shoulder movements.
If the damage is severe enough, it can cause paralysis of the deltoid and other minor muscles, resulting in flat shoulder deformity, in which individuals cannot lay their shoulders flat when lying down.
Axillary nerve damage also can lead to a change, reduction, or loss of sensation in a small part of the arm just below the shoulder.
Nerve Injury Statistics
Three times more common in men than women.
It may be present in as many as 65% of shoulder injuries.
The risk of injury due to dislocation is significantly increased after age 50.
Tests
If a healthcare provider suspects a problem with axillary nerve function, they’ll test the shoulder’s range of motion and skin sensitivity. A difference in the range of motion between the shoulders can indicate a nerve injury. Individuals may be sent for electromyography and a nerve conduction study to verify nerve palsy. In some cases, an MRI and/or X-rays may be ordered, especially if the cause of possible nerve damage is unknown.
Rehabilitation
Depending on the severity and cause of the injury, non-surgical treatments may be recommended, with surgery as a last resort. Non-surgical treatment can include some combination of immobilization, rest, ice, physical therapy, and anti-inflammatory meds. Physical treatment typically lasts about six weeks and focuses on strengthening and stimulating the muscles to prevent joint stiffness, which can impair long-term function.
Surgery
If conservative treatments don’t work, surgery may be recommended, especially if several months have passed without improvement. Surgical outcomes are generally better if surgery is performed within six months of the injury, and regardless of the time frame, the prognosis is considered positive in about 90% of cases. Surgical procedures performed for axillary nerve dysfunction or injury include:
Neurolysis
This procedure involves targeted damage/degeneration of nerve fibers, interrupts the nerve signals, and eliminates pain while the damaged area heals.
Neurorrhaphy
This procedure stitches a severed nerve back together.
Nerve Grafting
Grafting involves transplanting a portion of another nerve, usually the sural nerve, to reconnect severed nerves.
This helps, especially when the damaged portion is too large to be repaired by neurorrhaphy.
It allows a pathway for signals and encourages the regrowth of nerve axons.
Neurotization or Nerve Transfer
Similar to grafting but used when the nerve is too damaged to heal.
This procedure involves transplanting a healthy but less important nerve, or a portion of a nerve, to replace the damaged one and restore function.

The vastus lateralis is a muscle on the outside part of the thigh. Injuries to the muscle include strains, tendinitis, femoral nerve compression, and others. Can rehabilitation like heat and ice, massage, and strength and mobility exercises help individuals return to normal activities and function?
Vastus Lateralis Muscle
The vastus lateralis is the largest of the four quadriceps muscles on the thigh’s outer portion. The vastus lateralis helps extend the knee joint and maintain the knee position when walking or running. The vastus lateralis functions to work with the other quad muscles to help extend the knee joint.
Anatomy
Most muscles are attached to bone points of attachment, called the origin and insertion points. The vastus lateralis origin and insertion points are as follows (Vieira, EPL. 2017)
Origin
The origin is on the upper inter-trochanteric line of the femur or thigh bone.
It also arises from the base of the greater trochanter and the linea aspera, the supracondylar ridge, and the lateral intermuscular septum.
Insertion
From its origin, the muscle courses down the lateral thigh and inserts as part of the lateral quadriceps tendon on the tibial tubercle, an elevated portion of the upper shin.
The muscle is a large, flat structure with different attachments and a flat aponeurosis or sheath of connective tissue on the outer thigh.
The femoral nerve from lower back levels two, three, and four controls or innervates the muscle.
Blood supply to the muscle goes through the lateral circumflex femoral artery of the upper thigh.
Function
The muscle works with the other quadriceps muscles to extend or straighten the knee. The quads are responsible for functional activities like walking, running, climbing stairs, and getting up from a seated position. The vastus lateralis and the iliotibial band, which courses down the lateral thigh next to this muscle, form the lateral wall of the thigh. The vastus lateralis is on the opposite side of the vastus medialis muscle on the inner portion of the thigh. These muscles work together to maintain the appropriate position of the patella/kneecap in the femoral groove of the thigh bone. Malfunctioning these muscles properly can lead to knee pain from patellofemoral stress syndrome. (American Academy of Orthopaedic Surgeons, 2024)
Conditions
Many different injuries and conditions can affect the vastus lateralis and quad muscles, especially in athletes or active individuals. These injuries can cause vastus lateralis pain and other problems. (Timothy J. Von Fange, 2024) Some of the injuries and conditions include:
Patellofemoral Stress Syndrome – PFSS
This occurs when the kneecap tracks improperly in the femoral groove of the knee joint.
This leads to pain and difficulty when walking and running.
Vastus Lateralis Strain
A sudden force on the thigh can cause the quad muscle to be strained.
If the vastus lateralis suffers a pull injury, individuals may have pain, muscle swelling, thigh bruising, and walking difficulties.
Patellar Tendinitis
Irritation of the quad tendon that courses over the kneecap can cause patellar tendinitis.
Femoral Nerve Compression Weakness
The femoral nerve may become pinched or irritated from a herniated disc, lumbar stenosis, or arthritis.
Pain, numbness, tingling, or weakness in the thigh may result.
Iliotibial Band Friction Syndrome
Tight or weak muscles can irritate the IT band, and the vastus lateralis muscle can be affected.
Injury Rehabilitation
Injury to the vastus lateralis or quad muscles can cause pain, swelling of the thigh, or limited walking ability. Various treatments are available to help expedite recovery. A primary healthcare provider may recommend working with a physical therapy team. Self-care techniques can include:
Heat and Ice
Ice may be applied to the lateral thigh the first few days after injury to control pain and decrease swelling and inflammation.
Ice should be applied for 10 to 15 minutes.
Individuals may switch to heat two to three days after to promote circulation and improve tissue mobility.
Heat should be applied for 10 to 15 minutes.
Massage
Massage can help decrease pain and promote circulation.
Massage techniques can improve tissue mobility before stretching to help improve quadriceps motion.
Exercises and Stretching
A physical therapy team will prescribe certain exercises and stretches to help regain strength and range of motion. After an injury, quad stretching can improve the mobility and function of the muscle group.
Prone Towel Quad Stretch
Lie on your stomach and place a towel or strap around the ankle.
Bend the knee up, and gently pull on the towel to bend the knee fully.
A pulling sensation should be felt in the front of the thigh.
Hold the stretch for 30 seconds and release.
Repeat three times.
Half-kneeling Quad and Hip Flexor Stretch
Kneel on one knee.
Slowly move forward until a stretch is felt in the front of the hip and thigh.
Hold this position for 30 seconds.
Relax back to the starting position.
Repeat three times.
Back Exercises
If femoral nerve irritation coming from the lower back is causing thigh pain or weakness, exercises to release the nerve may be helpful and can include:
Prone press-ups
Supine lumbar flexion
Lumbar side glides
The exercises are designed to relieve pressure on the lumbar nerve, and postural correction exercises may be performed to maintain decompression.
Strengthening
Weakness to the vastus laterals and quads may be causing injury, and strengthening exercises may be prescribed during rehabilitation and can include:
Hip-strengthening exercises
Straight leg raises
Leg extension exercises
Lunges
Squats
Strengthening exercises should be done two to four times weekly with appropriate rest between sessions.
Balance exercises and sport-specific plyometric training may be recommended to ensure the quad functions normally.
Most quadriceps and vastus lateralis muscle injuries heal within six to eight weeks.
Recovery may be shorter or longer depending on the nature of the injury.

Individuals experiencing persistent pain, weakness, numbness, and tingling in the back could be suffering from nerve root encroachment. Could surgery ease nerve compression and improve symptoms for persistent and severe cases?
Surgical Decompression
The pain, weakness, numbness, and tingling associated with nerve root encroachment are usually first treated with non-surgical therapies that include:
Anti-inflammatory medications
Physical therapy
This can be enough to address the irritation of the spinal nerve root. But when cases become severe, surgical decompression may be recommended and necessary. It can be done in a couple of different ways.
Causes and Symptoms
Vertebrae are bones in the spine. Small openings called foramina allow a spinal nerve root to pass through on each side of the vertebra. When nerve root encroachment is present, the spinal nerve root gets compressed, pinched, and trapped, which can cause peripheral symptoms such as numbness, tingling, pain, or weakness to develop. Nerve root encroachment is typically caused by normal aging degenerative wear and tear changes in the vertebrae. (Choi Y. K. 2019) These degenerative changes can include:
Facet joint hypertrophy
Ligament and bone hypertrophy
Disc disorders
Formation of bone spurs or osteophytes.
If these degenerative changes progress, they can encroach and compress a nerve root, leading to peripheral symptoms. (Choi Y. K. 2019)
When Surgery Is Recommended
When symptoms occur, initial treatment will involve:
Physical therapy
Chiropractic realignment
Massage therapies
Rest
Lifestyle adjustments
Nonsteroidal anti-inflammatories – NSAIDs
Corticosteroid injections into the spine
If conservative therapies don’t fully heal or improve symptoms or there are neurological problems like difficulty with balance or walking, then surgery may be recommended. Severe pain that limits normal function is an indication for surgery, and rapidly progressive weakness of the arms and/or legs or signs of cauda equina syndrome are indications for emergency surgery.
Surgery Options
Different types of spinal surgery may be performed. A neurosurgeon will decide the best procedure for each patient based on their case, age, medical conditions, and other factors. Specific spinal surgical decompression depends on what is causing the nerve compression. In most cases, it involves removing bone or tissue to relieve nerve pressure or provide support to stabilize the joint. The most common types of surgical decompression include: (Mayo Clinic Health System, 2022)
Maintain the stability and alignment of the spine.
Improve the stability and alignment of the spine.
Anterior Surgery
The anterior approach to surgery means that the spine is accessed through the anterior/front of the spine. In this surgery, one or more discs and bone spurs may be removed through an incision in the front of the neck. (American Association of Neurological Surgeons, 2024) For example, an anterior cervical discectomy may alleviate pressure on one or more nerve roots in the neck. With an anterior lumbar interbody fusion, a surgeon removes a degenerative disc in the lower spinal area by going through a patient’s lower abdomen. (American Association of Neurological Surgeons, 2024) After the disc is removed, a structural device, usually made of bone, fills the space where it once was. This device encourages bone healing and helps the vertebrae’s bodies fuse.
Posterior Surgery
Posterior surgery means the spine is accessed through the posterior/back of the spine. An example is removing a thickened ligament, bone spur, or disc material in the neck. To do this, a small incision in the back of the neck may be made to remove part of the back of the vertebrae called the lamina. This is called a posterior cervical laminectomy. (American Association of Neurological Surgeons, 2024) A posterior lumbar interbody fusion removes a degenerative disc by going through the back. (American Association of Neurological Surgeons, 2024) Like the anterior approach, a structural device often contains bone to fill the space where the disc once was to fuse the bones.
Potential Risks
As with any surgery, it’s important that the individual and their healthcare provider carefully discuss the benefits and risks. Spinal surgical decompression includes: (Proietti L. et al., 2013)
Bleeding
Blood clots
Surgical site infection
Urinary tract infection
Lung infection
Intestinal blockage
There are also specific risks to the area of the spine being operated on and how it is surgically approached. For example, a cervical anterior procedure may injure the esophagus, trachea, or carotid artery. Likewise, damage to the C5 nerve root/C5 palsy can occur from cervical spinal decompressive surgery. This complication causes weakness, numbness, and pain in the shoulders. (Thompson S. E. et al., 2017) The spinal cord may also be injured during surgery and result in paralysis, although this is rare. (American Association of Neurological Surgeons, 2024)

What type of concussion tests are there to help establish the extent of head injuries and help assess improvement during recovery?
Concussion Tests
A concussion is a temporary change in brain function that occurs from a traumatic brain injury or TBI. It can cause problems with thinking and mood and can take weeks to years to heal. Concussion tests are done after a suspected head injury and are also used after diagnosis to assess healing progress. They are noninvasive tests that measure brain functions. Several tests vary in how they are given and what they measure.
Tests
A mild or moderate traumatic brain injury can cause damage to the brain that is not detectable with brain imaging tests. However, the damage can cause serious symptoms, including headaches, emotional changes, difficulty concentrating, and memory problems. (Haider M. N. et al., 2021) The effects of a concussion can be hard to describe, but concussion testing can help identify and quantify these changes. For individuals who don’t have time to heal or experience further brain injuries while recovering, the effects can be prolonged and worsen. This is one reason why concussion testing is vital to get a diagnosis and follow medical recommendations to avoid further injury to the brain. Diagnosis can help set goals, adjust, and assess how the effects improve over time. With improvement, individuals can participate in rehabilitation and follow their doctor’s instructions for gradually returning to work, school, and other activities.
Measurements
Concussion tests can measure subtle aspects of brain function, like visual or auditory perception and response speed (Joyce A. S. et al., 2015). The damage sustained can impair these abilities, like slow decision-making. A traumatic brain injury can be associated with serious injuries, like a skull fracture, swelling, bruise, or bleeding in the brain. These injuries can be detected with imaging tests and often require surgery or other interventions. Brain damage from bleeding or swelling would cause focal neurological symptoms and signs, including partial vision loss, numbness, and weakness. Individuals can have a concussion along with detectable brain injuries or in the absence of detectable brain injuries.
Types of Tests
There are several types of concussion tests. Individuals may have one or more of these, depending on the standard test that is used in their school, sports league, or by their doctor. These can include:
Online Checklists
Several different online checklists are available for concussion screening.
These tests may include questions about symptoms and are often used as self-tests but are not intended to replace an evaluation by a medical professional.
Baseline and Post-Injury Tests
Many schools and sports leagues conduct preseason skill measurements, including memory tests or tests of speed and accuracy, either in an interview form or with computer testing.
Individuals might be asked to retake the test that is used as a comparison if they have experienced a traumatic brain injury.
Standardized Assessment of Concussion – SAC
This five-minute test can be done on the sidelines after a sports injury or later.
It evaluates orientation, immediate memory, neurologic function, concentration, and delayed recall. (Kaufman M. W. et al., 2021)
King-Devick Concussion Test
This two-minute test can be performed on the sidelines after a sports injury or later to assess language, eye movement, and attention. (Krause D. A. et al., 2022)
Post-Concussion Symptom Scale
This test includes 22 questions involving neurocognitive factors, including difficulty concentrating or remembering, physical symptoms like headaches and dizziness, and emotional symptoms like sadness or irritability. (Langevin P. et al., 2022)
Sport Concussion Assessment Tool – SCAT
This test includes an on-field assessment noting concussion symptoms, memory assessment using Maddocks questions (a short list of specific questions), Glasgow Coma Scale (GCS), and cervical spine assessment.
An off-field assessment involves the evaluation of cognitive, neurological, balance, and delayed recall. (Kaufman M. W. et al., 2021)
Buffalo Concussion Physical Examination – BCPE
A modified physical examination that assesses neck tenderness and range of motion, head, jaw, and face abnormalities, eye movements examination, and coordination. (Haider M. N. et al., 2021)
After a concussion, individuals will also have a physical examination, including a full neurological examination, in a doctor’s office.
Results
A doctor will diagnose based on symptoms, physical examination, and concussion test results. For example, for individuals who have broken several bones and are taking powerful pain medications, concussion test results can be abnormal even if they did not experience a concussion. The results of concussion testing can be compared with results before the head injury. Often, baseline testing is required for participation in certain sports leagues at professional and amateur levels. A low score can indicate that head injury has impaired brain function. Sometimes, testing can be done within a few hours of the head trauma and then again a few days later. Responses of individuals who did not have measurements taken before a head injury can be compared with the average results of people their age.
