Over recent years, the detox has become a form of diet in its own right for losing weight with low-calorie regimens. As springtime arrives and some may have weight-loss programs in mind, here’s a look at five common myths about detox diets and whether they’re true or false.
Detoxing is a natural process
TRUE. In reality, detoxing is a natural process of purification that’s constantly underway in the body. When everything is functioning properly, the infamous toxins are destroyed and excreted by different organs in the body, known as emunctories: the skin, the lungs, the kidneys, the intestines and the liver. Toxins that accumulate in the body (food, air, tobacco, cosmetics, drugs, heavy metals, stress) are eliminated at varying speeds depending on your metabolism. You can help your body detoxify all year long, notably with foods rich in antioxidants like fresh fruit and vegetables that are organic and don’t contain pesticides.
A detox is a diet
FALSE. A drastic diet or a fast isn’t the same things as detoxing. The word diet has been wrongly associated with the concept of the detox, since the two approaches don’t have the same goal. In fact, the aim of a detox isn’t necessarily to lose weight. However, you should take care to avoid sugar, junk food and barbecued food which hinder the work of the emunctories.
Plant-based supplements can be helpful
TRUE. A course of certain plant-based dietary supplements or herbal teas can be used to support and optimize detox performances in periods of burn-out, stress or fatigue, for example. Artichoke, milk thistle, rosemary, turmeric, fennel, birch, dandelion, black radish, queen-of-the-meadow and fumaria are the most effective. Some plants, like chlorella, spirulina and laminaria japonica help combat heavy metals (mercury, aluminum, lead).
Juices and broths are a good way to detox
FALSE. Although they contain fruit and vegetables, juices, soups and broths have two drawbacks. First, they contain high quantities of sugar and salt, and have less fiber than eating the equivalent fresh fruit or vegetables whole. Second, a liquid-only diet isn’t advisable, as you could end up starving yourself, since the body needs a minimum amount of protein to function. Small quantities of white meat or pulses are recommended to boost the detox process. And don’t rely on a soup + herbal tea + yogurt combination for your evening meal, as this can favor water retention. However, drinking lots of water (1.5l per day) is recommended.
Massage can help flush out toxins
TRUE. Massages in the abdominal region — home to three groups of emunctory organs: the liver, the kidneys and the intestines — can help flush out toxins. But lymphatic drainage is even more effective, promoting blood circulation and helping the lymphatic system to drain out waste substances which aren’t filtered out by blood.
If you live in the city, you might want to make sure you take your vitamins. A study from Columbia University found that B vitamins reduce changes to the epigenome — the chemicals that regulate and direct genes — caused by air pollution.
The study reveals even small amounts of the vitamins could counteract the damage caused by tiny, toxic pollutant particles called PM2.5, which include toxins such as sulfate and black carbon. These pollutants are often deposited in the respiratory tract resulting in inflammation in the lungs and throughout the body.
According to the World Health Organization, about 92 percent of the world’s population lives in areas where pollution is higher than safety levels set by the WHO. The U.S. also has pollution problems. The American Lung Association says that 47 percent of Americans live in areas that often have dangerously high levels of pollution.
“The molecular foundations of air pollution’s health effects are not fully understood,” said Dr. Andrea Baccarelli. “Our study launches a line of research for developing preventive interventions to minimize the adverse effects of air pollution.”
For the study, researchers gave adult volunteers a B-vitamin supplement (2.5 mg of folic acid, 50 mg of vitamin B6, and 1 mg of vitamin B12) or a placebo daily for four weeks. Participants were healthy non-smokers, 18 to 60 years old, who were not taking any medicines or vitamin supplements. They were then exposed to pollution particles.
Blood tests showed that levels of B vitamins increased significantly in those taking the supplements. Tests also found that while the PM2.5 pollutants can turn off cells in the immune system, supplementing with B vitamins limited their effect by up to 76 percent.
“As individuals, we have limited options to protect ourselves against air pollution,” said Baccarelli. “Future studies, especially in heavily polluted areas, are urgently needed to validate our findings and ultimately develop preventive interventions using B vitamins to contain the health effects of air pollution.”
The study’s results are published in the journal Proceedings of the National Academy of Sciences (PNAS).
Created by the Academy of Nutrition and Dietetics, National Nutrition Month® is celebrated annually every March to help everyone make more informed food choices and develop healthier eating habits for improved well-being.
With many recent studies focusing on the benefits of a diet that includes probiotics, also known as “good” bacteria, and prebiotics, which act as food for probiotics and promotes their growth, here we round up some of ways that boosting levels of good bacteria could improve various conditions and overall health.
Reduce social anxiety
A 2015 study of 700 students participants found that eating fermented foods, a good source of probiotics, is associated with reduced symptoms of social anxiety.
The study, published in Psychiatry Research, also found that the link between fermented foods and reduced social anxiety was strongest among those who already rated high in neuroticism.
The findings came after an earlier study published in The Lancet Psychiatry stated that an increasing amount of evidence suggests an important relationship between the quality of diet and mental health.
Improve sleep, protect against stress
A study published just last month found that prebiotics, can help improve sleep and protect against the negative effects of stress.
The team of researchers fed 3-week-old male rats a diet of either standard chow or chow that included prebiotics, and found that those on the prebiotic diet spent more time in non-rapid-eye-movement (NREM) sleep, which is restful and restorative, than those on the non-prebiotic diet.
Rats who were on the prebiotic diet also spent more time in rapid-eye-movement (REM) sleep after being exposed to a stressor, with REM sleep is believed to be critical for promoting recovery from stress.
Previous research has also shown that stress can reduce healthy diversity of gut bacteria, but the rats on the prebiotic diet maintained a healthy and diverse gut microbiota even after exposure to stress.
Reduce obesity
A 2015 study confirmed a link between balanced intestinal flora and weight loss.
The study, published in the journal Obesity, showed that while following a four-week high-fat diet the men who drank a probiotic milkshake containing VSL3, a probiotic with multiple strains of bacteria including Lactobacillus acidophilus and Bifidobacterium longum, put on less weight than others following the diet who drank a placebo milkshake.
The researchers think that probiotics could have changed gut bacteria in a way that resulted in less body fat accumulation, and that the probiotics could have reduced fat absorption.
Reduce risk of allergies
Prebiotics have been shown in various studies to help reduce the risk of allergies.
A French study using mice found that those who received prebiotics had a lower risk of developing a wheat allergy thanks to the prebiotics improving the immune system’s tolerance to allergens, while a US study by the University of Chicago also found that in infants who had trouble tolerating cow’s milk, a new probiotic not only got rid of the allergy, but also changed the composition of their gut bacteria significantly.
A separate study also from the University of Chicago, found that supplementing rodents with probiotics containing the bacterium Clostridia later in life could reverse a peanut allergy.
Many are starting to wonder why more and more kids are starting to be under regular Chiropractic care. For some, this may sound mysterious, but for others who understand what Chiropractic care provides for children, they realize it is much more than fixing back pain.
According to world renowned Chiropractor and author, Dr. Jennifer Barham- Floreani, �The nervous system is the master controller of our body and if its communication channels become fuzzy, distorted or damaged then we may experience all sorts of communication errors. For babies this ineffective communication may play out as colic or irritability, an inability to suckle and breastfeed or poor sleep habits. For a child poor nerve communication may result in developmental delays, an inability to concentrate, behavioral problems, digestive issues, asthma, headaches � the list is endless.�
How can your child�s body lose its natural alignment and develop subluxations? Studies have shown that in the majority of cases, trauma (often unrecognized) from the birthing process or procedures causes subluxation of the infant�s spine. Subluxation damage can be caused by a constricted uterus, a breech presentation or a difficult delivery, and in cases of vacuum extraction or excessive force, the spine is always traumatized. Health problems in childhood or even adulthood have been traced back to spinal and structural damage at birth in many cases.
Abraham Towbin, MD states: �The birth process � is potentially a traumatic, crippling event � mechanical stress imposed by obstetrical manipulation-even the application of standard orthodox procedures may prove intolerable to the fetus � most signs of neonatal injury observed in the delivery room are neurological.�
Research is confirming chiropractors� observations that infants may suffer from spinal subluxations. In one study, 1,250 babies were examined five days after birth; 211 of them suffered from vomiting, hyperactivity and sleeplessness. Subluxations were found in 95% of this group. Although the researchers in this study were MDs, they recognized the power of chiropractic care and these babies were given the care they needed.
The spinal adjustment �frequently resulted in immediate quieting, cessation of crying, muscular relaxation and sleepiness.� The authors noted that an unhealthy spine causes �many clinical features from central motor impairment to lowered resistance to infections- especially ear, nose and throat infections.� The above study discusses an 18-month-old boy suffering from tonsillitis, frequent enteritis, therapy-resistant conjunctivitis, frequent colds, earache and increasing sleeping problems.
He received a chiropractic spinal adjustment. The child demanded to be put to bed and slept peacefully until morning. His health returned to normal. One wonders, what would have happened to this child if he never had chiropractic care? A life of antibiotics and other medications? A life of continued sickness?
The authors of the above-mentioned study concluded that a chiropractic spinal checkup �should be obligatory after every difficult birth� and any spinal stress �should be � adjusted � the success of adjustment overshadows every other type of care.�
According to the Chiropractic pediatric specialist Larry Webster, DC, there are six times in a baby�s first year of life when chiropractic examinations are especially important:�
After the birth process.
When the baby starts to hold his/her head up.
When the baby sits up.
When the baby starts to crawl.
When the baby starts to stand.
When the baby starts to walk.21
Toddlerhood through childhood is a very �physical� time. Those first hesitant steps soon evolve into jumping, running, falls and accidents which are all part of a normal childhood. While most falls are minor, at times they can cause nerve-damaging subluxations with serious long-term consequences. For that reason all children need periodic spinal check-ups.
What are the Benefits of Chiropractic for Kids?
Over many decades parents, clinicians, and researchers have noticed positive changes in behavioral, physical, and emotional health of children under chiropractic care. Many different behavioral conditions have been observed to improve with chiropractic care including ADD/ADHD, anxiety, and also focus, concentration, and grades in school.
Since the nerves collectively control and influence all bodily functions, removing nerve interference may result in improvement of many different health problems depending on the area of the spine and nervous system involved. Improvement is commonly seen in conditions such as colic, constipation, ear infections, allergies, asthma, sinus infections, persistent bed wetting, stomach aches, �growing pains� in the legs or arms, headaches, back and neck pain, scoliosis, and abnormal gait among others.
What�s the Best Reason to Have Your Kids Under Regular Chiropractic Care?
We believe that the best reason to do any health related activity is for wellness and prevention. And it is easier to grow healthy children than to repair damaged adults. Life is so much better when your children never seem to get sick or have health problems than when you are routinely going from appointment to appointment constantly treating the symptoms of ill health.
It is not unusual to hear parents state that since starting chiropractic care their children get sick less frequently and less severely, have less ear infections, and take less antibiotics and other drugs than their classmates. Our vision is to use chiropractic today for a better world tomorrow. Starting from birth, remove interference to the body�s inborn ability to heal itself and allow children to reach their health potential throughout their life.
10 Reasons Parents Take Their Children to See a Chiropractor
To encourage good neural plasticity (brain and nerve development).
To support �first-class� nerve communication throughout the body to promoting health and wellbeing.
To help strengthen their child�s immunity � encouraging fewer colds, ear-aches and general illness.
To help resolve breastfeeding issues and colic.
To reduce the detrimental impact our modern world has on our children�s health.
Encourages children to thrive by supporting digestive strength.
To diminish nerve interference which may impact their child�s capacity to learn and concentrate.
To promote body balance � helping to resolve poor posture, asthma, allergies and bed-wetting..
For a child poor nerve communication may result in developmental delays, an inability to concentrate, behavioral problems, digestive issues, asthma, headaches. Parents, clinicians, and researchers have noticed positive changes in behavioral, physical, and emotional health of children under chiropractic care.�For Answers to any questions you may have please call Dr. Jimenez at 915-850-0900
Walk into any gym or health club and you�ll find people exercising�their core. Coretraining has�taken the world by storm, and for good reason, as every DC knows. Strengthening the�core creates stability and better movement and helps prevent lower back pain. To help patients get the most from�their efforts, it�s important they understand what they�re doing. You can explain the difference between the local and global muscles, as I�ve outlined�below, and help your patients�perform core work safely and effectively.
What Is the Core?
I like to tell patients that their core is a shorthand way of referring to all the muscles of their�lower back/pelvis/hip area. It�s where your center of gravity is located and where movement begins. A strong core stabilizes the spine and pelvis and supports you as you move. The core has 29 pairs of muscles that�fall into two categories:
��Local Muscles. Patients can think�of local muscles as the deeper muscles, the ones close to the�spine and responsible for stabilization.�They don�t have much ability to move the�joints. The local muscles are further broken down into primary and secondary categories. The primary local muscles are the transverse abdominus and multifidi (the two most critical muscles for providing stability). The secondary local muscles are the internal obliques, quadratus lumborum, diaphragm and pelvic floor muscles.
��Global Muscles.�The global muscles are the outermost layer of muscle�they�re the ones you can feel through your skin. They�re responsible for moving joints. The global muscles in the core are the rectus abdominus, external obliques, erector spinae, psoas major and iliocostalis.
The core should operate as an integrated functional unit, with the local and global muscles working together to allow easy, smooth, pain-free movement. When the muscles work together optimally, each component distributes, absorbs and transfers forces. The kinetic chain of motion functions efficiently when you do something dynamic, like exercise or run.
Core Injury
An injury to one of the core muscles usually means an episode of lower back pain for your patient. When that happens, the deep stabilizers change how they work as a way to compensate for the injury and protect the area. The stabilizers now have delayed action; they�re turned on only after you move, instead of as you move. Because now they�re not functioning as they should, the�brain recruits the�global muscles to compensate. That causes a core imbalance. The result: pain in the lower back, pelvis and glutes (the big muscles you sit on).
Exercises designed to help get patients� core muscles back in balance are the best way to prevent re-injury and avoid lower back pain. Traditional abdominal exercises are often recommended to strengthen the global muscles. These exercises can actually increase pressure on the lower spine. Similarly, traditional lower back hyperextension exercises meant to stretch out the lower spine also may actually increase pressure on it. A better approach to preventing lower back pain is restoring stability with the core exercises below.
Abdominal Brace
The abdominal brace activates all the contracting muscles in the abdominal wall, without involving the nearby obliques and rectus muscles. This exercise strengthens the connection between the global muscles and the deep local muscles. This helps restore the balance between them and improves spinal stiffness.
To get an idea of how the muscles in your core work, place your thumbs in the small of your back on either side of your spine. Next, do a hip hinge: bend forward from the hips about 15 degrees. You should feel the muscles in your lower back move as you bend and stand back up again.
To do the brace, stand upright and suck in your stomach, as if you were about to get punched. Hold hat for 10 seconds, then relax. Repeat 20 times; do three sets.
You�ll know you�re doing the brace correctly if you poke your extended fingertips right into your side below your ribs and then brace. You should feel the muscles move under your fingertips.
Curl-Ups
Curl-ups train the rectus abdominus, the long abdominal muscle that runs vertically from your breastbone all the way down on both sides of your bellybutton.
Start by lying on your back with your hands palm-up beneath your lower back. Bend one leg and put the foot flat on the floor; extend the other leg. Hold your head and neck stiffly locked onto your ribcage�imagine them as one unit. Lift your head and shoulders slightly off the floor by three or four inches and hold that position for 20 seconds. Your elbows should touch the floor while you do this. Relax and gently lie back again. Repeat 10 times. Switch legs and repeat 10 times gain. Do three sets.
Tip: If your patient has�neck discomfort doing this, have them push their�tongue against the roof of the�mouth�to help�stabilize the neck muscles.
Side Bridge
The side bridge, also called the side plank, trains the quadratus lumborum, lateral obliques, and transverse abdominus muscles, all local muscles that help stabilize the�spine.
Start by lying on your side. Place your top leg in front of your bottom leg (the heel of your top foot should touch the toe of the bottom foot). Raise your body using the down-side shoulder and elbow. Cap the opposite shoulder with your free hand. Hold for as long as you can, aiming for 30 seconds. Switch sides and repeat.
Bird Dog
This exercise is great for training the back extensors, including the longissimus, iliocostalis and multifidii.
Start on your hands and knees (quadruped position). Raise and extend the opposite arm and leg simultaneously, like a dog pointing to where the bird is. �Hold or eight seconds, then return to the quadruped position. Repeat eight times, then switch arms and legs and repeat for eight reps. Do three sets.
Conclusion
All the muscles of the�core must work together to produce efficient and effective movement. The core is the center of the�body�s motion�training it is a critical part of any exercise routine. Teaching your�patients proper technique for core training will result in�big benefits for them now and in the future.

Sometime after Kyle Gibson starts for the Twins in their home opener Monday afternoon, the durable young right-hander will connect with perhaps the most important member of his support team this year: his Chiropractor.
Gibson is still just 28, smack in the prime of his career, but there were times during the second half last season when his lower back started to bark at him. In early August in Toronto, for instance, he was shelled for eight earned runs in just 4 2/3 innings.
�I had a problem in Toronto,� Gibson said.
�There were a couple starts where I didn�t sit down in between innings,� Gibson said, �because if I sat down, my hips just got tight.�
Meanwhile, fellow Twins pitcher Trevor May, 26, was dealing with lower back issues of his own. In May�s case, the additional pounding of making multiple relief appearances without much recovery time had caused issues with the hip and lower-back area of his left (landing) leg, as well.
May�s physical woes left him unavailable for days at a time while the Twins chased their first postseason berth since 2010. Massage and electronic stimulation could only do so much to keep May on the mound.
A few sporadic sessions with a chiropractor didn�t provide immediate results, so May discontinued them.
Upon returning to Seattle this offseason, the yoga devotee decided to up the ante and visit a chiropractor weekly for hour-long sessions. This time, he began to see the benefits.
�A couple weeks before spring training, I felt it coming on a little bit again,� May said. �I was like, what is going on? I got it adjusted and my chiropractor said, �Man, you are way, way out of whack.� He explained to me where my pain was and why the hip was pressing against where it was and if we get that moved back, just lengthened out, it�s going to be really sore for a few weeks, but then it�s just going to go back to normal.�
OVERCOMING FEARS
In 2014, his first full season in the majors, Gibson saw a chiropractor a few times at the recommendation of Twins closer Glen Perkins.
Gibson missed a start in late July after getting shelled at home for six earned runs against the Tampa Bay Rays.
�One of Perk�s guys came in and adjusted me,� recalled Gibson, who threw seven shutout innings at Kansas City his next time out.
That never led to a regular appointment, partly because of Gibson�s relative youth but also because of a long-held fear of what a chiropractor might do to a young athlete�s spine.
�My view of them was, �OK, I want you to lay on a table and I�m going to pop your back and you can come back in a week,� � Gibson said. �Once you start doing it, you�ve got to keep doing it the rest of your life. That was my view.�
A conversation with May early in spring training this year left him more open to chiropractic manipulation.
Hoping to build on the gains of a breakthrough 2015 but still bothered by soreness in his lower back, Gibson asked May for feedback on his chiropractor. May, who by then was going once at week to Darin Stokke at Lifestyles Chiropractic, had nothing but good things to say about the sessions.
Dr. Stokke
�We found that baseball players get skeletally out of line,� May said. �They do one motion one way much harder (than most people), and my hips were really, really out of line. Seeing a chiropractor consistently has helped me make sure I�m getting readjusted and staying in line as much as possible.�
While initially there was some concern that the bullpen simply did not agree with May�s back, his chiropractic sessions convinced him (and the Twins) that he could manage the additional workload with proper preparation.
What derailed him in September 2015, as it turns out, was a problem with the set joint, where the left hip and lower back meet.
�It was all muscular,� May said. �It was just because one hip was closer to the spine than the other side. The other side was normal. (The left side) was just pressing so much and you get so much inflammation. It was just a perfect storm. It was just a little extra torque being in the �pen. That�s why it was bothering me. Now I�m on top of it.�
As May explained it to Gibson, realignment of the spine would allow the overtaxed areas of a pitcher�s core to meet the challenge of persistent pounding.
�Letting those muscles unflare and then heal and rebuild them back to where they�re supposed to be, that�s what we�re doing,� May said.
After doing some �normal treatment stuff� as a warmup, Stokke would check May�s alignment much the way a tire installer might need to check an automobile before sending it back out into traffic.
�He checks where you legs are,� May said. �If he sees you�re out of line, he puts you back in line, and the next day I try to do some exercises and heavy strength stuff, just to build those muscles back up. I�m seeing soreness go and I feel more in line and healthier.�
BELIEF SYSTEM
Despite taking the loss in his season debut in Baltimore, Gibson reports much the same results from his twice-weekly chiropractic sessions this spring.
�Toward the beginning of spring training my back started getting sore again,� Gibson said. �Going twice a week helped get things moving in the right direction.�
Now that he feels his lower-back problems are under control, Gibson plans to scale back to a single visit per homestand. That way he won�t have to find somebody to visit on the road, while also limiting those realignment sessions to perhaps two per month.
�It has made a big difference in my hips and just everything,� said Gibson, who set career highs for starts (32) and innings (194 2/3) last season. �My skeletal system was basically allowing my muscular system to stay tight and not function properly. That caused some nerve irritation.�
While May features the classic �drop and drive� delivery, Gibson is from the �tall and fall� school that should, in theory, produce less strain on a pitcher�s hips and back. That didn�t prove to be the case over Gibson�s first few seasons in the majors, so he finally realized adjustments were needed.
�Some of my problem was just that I had some tight hips pulling my pelvis out of line and causing some irritation in the nerve,� Gibson said. �There were certain things I realized I could pitch through. You find ways to get around certain sorenesses and aches and pains.�
If the Twins can get 200 innings out of Gibson and 65 to 75 relief appearances out of May, they won�t just have a better chance to end a postseason drought that has reached five years and counting. They could have additional members of their pitching staff lining up for realignment sessions.
Kyle Gibson, last season his lower back started to bark at him. The durable young right-hander connected with the most important member of his support team, his Chiropractor. While Trevor May, was dealing with lower back issues of his own. In May�s case, the additional pounding of making multiple relief appearances without much recovery time had caused issues with his�hip and lower-back area of his left (landing) leg, as well.
Proven�research is now indicating that receiving Chiropractic adjustments to the pelvis can�increase vertical jump height. �This new research further solidifies the stance of many professional and collegiate teams with providing Chiropractic care for their athletes. In addition to injury prevention this research proves that chiropractic care results in an increase in sports performance.
[Purpose] This study aimed to investigate the effect of pelvic adjustment on vertical jump height (VJH) in female university students with functional leg length inequality (FLLI). [Subjects] Thirty female university students with FLLI were divided into a pelvic adjustment group (n = 15) and a stretching (control) group (n = 15). [Methods] VJH was measured using an OptoGait. [Results] After the intervention, jump height improved significantly compared with the pre-intervention height only in the pelvic adjustment group, while FLLI showed statistically significant improvement in both groups. [Conclusion] Pelvic adjustment as per the Gonstead method can be applied as a method of reducing FLLI and increasing VJH.
Key words:�Pelvic adjustment, Functional leg length inequality, Vertical jump height
INTRODUCTION
The pelvis, a structure located between the hip joint and the lumbosacral spine and attached to several muscles, regulates the movement of the hip joint and lumbosacral spine. The position of the pelvis is the most critical factor determining the sagittal alignment and posture of the human body). Only when the pelvis is in the neutral position can be in the right posture, move the upper and lower body in the dynamic posture, and improve daily movements and ambulatory ability).
Functional leg length inequality (FLLI) worsens due to pelvic tilt in the medial plane and pelvic rotation in the sagittal plane). Therefore, FLLI might be improved by pelvic adjustment. High-velocity and low-amplitude (HVLA) adjustment has been widely utilized as a general chiropractic adjustment method). Many studies have indicated that leg length inequality (LLI) causes posture alteration), limiting exercise and causing tension of the muscles and other soft tissues5). LLI is accompanied by several clinical symptoms6)�such as lumbar pain)�and hip pain). Correcting leg length inequality reportedly reduces pain, increases mobility, and improves posture).
Vertical jumping is practiced to enhance the muscular strength and endurance of the leg and serves as a barometer of muscular strength). There have been studies in which plyometric training was undertaken to improve leg muscle strength), dynamic stretching was applied after jogging for 5 minutes to improve vertical jump height (VJH), or HVLA manipulation was performed for talocrural joint dysfunction). However, there has been no study in which FLLI was corrected and VJH was measured as a barometer for leg muscle strength. Many studies have assessed the effect of pelvic adjustment on FLLI), posture), pressure on the foot, and balance). However, no study has investigated the changes in FLLI and VJH resulting from just a single adjustment. Therefore, this study aimed to assess the immediate effects of a single pelvic adjustment on FLLI and VJH in female university students with FLLI.
SUBJECTS AND METHODS
A total of 30 female university students with an FLLI of more than 10?mm between the left and right legs were selected and randomly assigned to one of two groups: the pelvic adjustment group (adjustment group, n = 15) and control group (stretching group, n = 15). The exclusion criteria were as follows: anatomical LLI; degenerative osteoarthritis; muscle, bone, or nervous system problems; ankle joint, knee joint, hip joint, or lumbar pain; limited range of motion due to burn or postsurgical scarring; and regular leg exercise. This study was approved by Korea Nazarene University�s Institutional Review Board, and the safety of all subjects was protected during all parts of the experiment. All subjects understood the purpose of this study and provided written informed consent prior to participation in accordance with the ethical standards of the Declaration of Helsinki.
The age, height, and weight of the subjects in the adjustment group were 23.5�4.7?years, 163.0�5?cm, and 54.1�5?kg, while those in the stretching group were 22.2�6.3?years, 162.7�6?cm, and 53.1�6?kg, respectively. Gender was analyzed using the ?2�test, while age, height, and weight were analyzed using the independent t-test. As these analyses detected no statistically significant differences (p>0.05), the two groups were deemed identical.
The pelvic adjustment performed in the adjustment group consisted of an HVLA technique administered in the prone posture in accordance with Gonstead�s theory. Subjects were instructed to lie prone, their pelvic height was checked, and the posterior-inferior innominate bone was given an anterior-superior impact while the anterior-superior pelvis was given a posterior-inferior impact. When making these impacts, the therapist put one of his hands on top of the other, placed them on the posterior-superior iliac spine or the ischial spine, and then gave the impact using his own weight, gravity, and acceleration). This adjustment was performed 3�5 times by one skilled physical therapist with more than 10?years of clinical experience. The control group stretched the backbone erector, rectus abdominis, iliac muscle, psoas major, quadriceps muscle, leg adductor, and quadratus lumborum adjacent to the pelvis in order to resolve muscular imbalance that could further the pelvic imbalance. In the process, the therapist assisted the subjects in performing additional height training for each muscle and maintaining each posture at the maximum height for 10�15 seconds. The subjects then resumed the initial posture, rested for 5 seconds, and repeated the stretching one more time. Stretching was done three times per posture for a total of 15 minutes).
For leg length measurement, subjects lay straight on a bed, and the tape measure method (TMM) was used to measure the leg from the anterior superior iliac spine (ASIS) to the medial malleolus. Beattie et al. reported that LLI as measured by the TMM did not show a significant difference from radiological findings. We were therefore confident in the reliability of using the TMM for measuring leg length). The measurement started from the ASIS so that pelvic bone-related problems such as pelvic tilt and pelvic asymmetry could be included.
We used an OptoGait (Microgate Srl, Bolzano, Italy), a system for optical detection, to analyze ambulation and measure VJH. On its signal-sending bar, there are 96 LEDs that communicate via an infrared frequency. The signal-receiving bar has an identical number of LEDs. We installed the signal-sending and signal-receiving bars of the OptoGait one meter apart on a flat surface. When a subject performs a vertical jump between the bars, the bars calculate the time at which the subject touches the floor or stays in the air and communicates this information by sending and receiving 1,000 signals per second, generating accurate data. Based on this basic data, the OptoGait software calculates the precise VJH.
Leg length and VJH were measured before and after the intervention. The measured data were analyzed using the statistics program SPSS 12.0 KO (SPSS, Chicago, IL, USA), and the collected data are presented as averages and standard deviations. The significance of pre- and post-intervention differences was tested using the paired t-test, and the significance of between-group differences was tested using the independent t-test. The p-value ? was set at 0.05.
RESULTS
In the pre- and post-intervention comparison, VJH improved significantly only in the adjustment group, while FLLI improved significantly in both the adjustment group and the stretching group (p<0.05) (Table 1). When comparing the pre-intervention data, post-intervention data, and changes between the pre- and post-intervention data, VJH showed statistical significance only for the changes between the pre-and post-intervention data, while FLLI showed statistical significance for post-intervention data and changes between the pre- and post-intervention data (p<0.05) (Table 2).

DISCUSSION
The pelvis supports the abdomen, connects the spine and legs, and is involved in transferring weight from the spine to the legs when a person stands up, maintaining a straight posture and enabling smooth arm movements). Due to their erect ambulation, human beings are exposed to gravity and can thus be subject to a malalignment of the pelvis and legs affecting posture, ambulatory pattern, and balance. LLI is easily observed clinically and causes functional disturbance of normal biomechanics).
Winter and Pinto reported that pelvic obliquity is caused by LLI), and Mccaw and Bates explained the relation between biomechanics and spinal deformity due to LLI). Defrin et al. reported that when a shoe insert was used in 22 chronic back pain patients with LLI of 10?mm and less, pain intensity and muscular weakening were reduced), which appears to be due to reduced pain and muscular weakening attributed to decreased pelvic tilt resulting from LLI adjustment. On the basis of previous studies on pelvic adjustment, Alcantara et al. reported that following adjustments using fast and slow speed amplitudes in patients with sacroiliac joint obliquity, pain was reduced, and patients could resume daily life and work). Park et al. reported that balance in 20 elderly men was improved through pelvic adjustment according to the Gonstead method). In this study, FLLI was reduced after pelvic adjustment, a finding similar to a previous study in which pelvic adjustment helped reduce FLLI and the pressure difference between soles).
In this study, stretching was not associated with increased VJH, while pelvic adjustment was. In a previous study by Ryan et al. in which subjects jogged for 5 minutes in order to improve VJH, a barometer for leg strength, and then performed dynamic stretching, VJH was increased as compared with a control group that only jogged for 5 minutes). In the present study, it is suspected that VJH did not increase because only static stretching was applied. Hedlund et al. reported that VJH showed a statistically significant increase following 3 weeks of chiropractic HVLA manipulation in 22 female handball players with talocrural joint dysfunction, which is similar to the findings of the present study).
Pelvic adjustment balances the left and right pelvic height and left and right anterior and posterior rotation of the hip bones, which, in turn, leads to FLLI improvement. It also balances the left and right muscle lengths of the rectus femoris and sartorius, which are involved in the hip bone�s anterior rotation, and the hamstring and gluteus maximus, which are involved in posterior rotation. This seems to explain the improvement in vertical jump ability. We recommend that pelvic adjustment be applied for decreasing FLLI and increasing VJH, a barometer for leg muscle strength, in the future.
Research now indicates that receiving Chiropractic Adjustments to the pelvis can�increase vertical jump height. �This research solidifies many professional and collegiate teams that�provide chiropractic care for their athletes. In addition to injury prevention this research proves that chiropractic care results in greater athletic performance.

According to world renowned Chiropractor and author, Dr. Jennifer Barham- Floreani, �The nervous system is the master controller of our body and if its communication channels become fuzzy, distorted or damaged then we may experience all sorts of communication errors. For babies this ineffective communication may play out as colic or irritability, an inability to suckle and breastfeed or poor sleep habits. For a child poor nerve communication may result in developmental delays, an inability to concentrate, behavioral problems, digestive issues, asthma, headaches � the list is endless.�
Curl-ups train the rectus abdominus, the long abdominal muscle that runs vertically from your breastbone all the way down on both sides of your bellybutton.
The side bridge, also called the side plank, trains the quadratus lumborum, lateral obliques, and transverse abdominus muscles, all local muscles that help stabilize the�spine.
This exercise is great for training the back extensors, including the longissimus, iliocostalis and multifidii.
A total of 30 female university students with an FLLI of more than 10?mm between the left and right legs were selected and randomly assigned to one of two groups: the pelvic adjustment group (adjustment group, n = 15) and control group (stretching group, n = 15). The exclusion criteria were as follows: anatomical LLI; degenerative osteoarthritis; muscle, bone, or nervous system problems; ankle joint, knee joint, hip joint, or lumbar pain; limited range of motion due to burn or postsurgical scarring; and regular leg exercise. This study was approved by Korea Nazarene University�s Institutional Review Board, and the safety of all subjects was protected during all parts of the experiment. All subjects understood the purpose of this study and provided written informed consent prior to participation in accordance with the ethical standards of the Declaration of Helsinki.
