muscle imbalance
LindaRacine
If muscle imbalance causes scoliosis, why isn't it 100%? I have a niece who had special xrays taken of her legs, to measure the bones in her legs. Her leg length discrepancy is 1-1/2", but she has a completely straight spine.

Hi there: I've read all your replies, and see that Dingo has linked to a study on young athletes and scoliosis. There are several more studies out there, showing that scoliosis appears to be more common in certain sports, such as ballet, tennis, swimming etc. (sports with asymetrical loading of the spine). Javelin throwing was also mentioned.
Muscle imbalance ALONE cannot "cause" AIS. It is pretty agreed upon by all the posters so far, and the research community, that AIS is multifactoral and likely has some neurologic components.
Functional scoliosis can certainly be CAUSED by imbalance however (non deformed bones, curves in standing that disappear in supine). This categery contains some of the scoliotic athletes, people with serious trunk imbalances, leg length discrepancy and herniated discs.
Originally posted by Pooka1 View PostIn my ceaseless efforts to learn how to ride and train horses, I have had the luxury over the years of not only taking a bazillion lessons but auditing five bazillion lessons.
What becomes obvious is that not only does almost every person have a stronger side but EVERY horse has a stronger side.
Lower level riders struggle to feel this sidedness and force themselves to come exactly even.
Upper level horses who are trained to follow/turn from small differences in weighted seatbones will TELL you how uneven you are if you try to ride a straight line without reins or legs... just from weight cues in the seat.
Because most people don't make it out of the lower levels, I suspect one reason is they never even out their sidedness. In some cases, these people CANNOT turn the horse in a particular direction just from their weight because they are so one-sided in their strength.
The points I'm making are as follows:
1. Most people have a strong and weak side.
2. Some people have a VERY marked difference in their strong and weak side.
3. Most people don't have scoliosis.
And ps... although every horse I've ever ridden had a strong and weak side, I've never met one with scoliosis yet.
Re: point #2 above, Pooka1:
Your method for determining this is, I assume, observation of the rider with your eyes. So though you may see something "very marked" you have no way of knowing which tissues the imbalance is. In one rider, it could be a weak arm due to a rotator cuff strain, in another it could be internal scarring from their abdominal surgery that makes their pelvis turn a certain way. In another it might be "habit" or uncoordination, and not strength at all.
I do not think that points 1 and 2 lead automatically to point 3. Stong vs. weak must be detrermined from observation, followed by a comprehensive physical exam including many specific strength tests.
While I don't think imbalance CAUSES scoliosis, it is certainly a hallmark symptom of the disease, and needs to be addressed. The research community does know a lot about the integrated functioning of the musculoskeletal system, but it doesn't know a lot too .... what if muscle training to correct imbalances has an effect on the neurological system such that that effect of the as-yet-unknown cause of bony wedging could be dampenned? Bones are living tissues constantly being degraded and rebuilt and remodelled..... just a thought. Anyone seen an article on this?

As a person who spends nearly all day evaluating joints, muscles, and the integrated function of the body segments, I do agree that most people have differences in muscle balance. Often I am asked the chicken-egg question - did the muscle imbalance cause the problem, or did something ELSE cause the problem that led to the muscle imbalance? Sometimes the question is unaswerable, but the treatment approach is often - doesn't really matter which came FIRST, the point is, you've got the painful condition now, and the imbalances must be corrected to solve the problem.

We need rational folks who can talk about alternative treatments in PERSPECTIVE. They are not so common as can readily been seen.Sharon, mother of identical twin girls with scoliosis

Originally posted by Pooka1 View PostWell, I think Hawes's case may be evidence that if you exercise FOUR hours a day for SEVERAL years you can get some measurable decrease in your curve that may be due in part to bone remodeling. But more likely I think her curve would revert to the original value if she stopped. I think she exercises one hour a day now but don't really recall.

I should totally be spending my afternoon off preparing pelvic floor stuff for work, but I can't resist replying to you about swimming!
Personally, although I love to swim, I would never swim lengths for excercise as a person with scoliosis, for worry that my rib hump would get larger, not smaller, which is my aim with the Schroth style exercises that I do now.
Because swimming is such an aerobic activity, requiring deep, heavy breathing, and air follows the path of least resistance on it's way down, it would only serve to further expand the already overexpanded rib hump. I've always wondered why so many people with scoliosis are told to swim lengths, and since a scoliotic person usually lacks neck rotation to one side, the person could further feed into his curves by always turning the head the same way.

Sorry to repeat what I said a long time ago, but maybe someone, someday will investigate the effect of a fall on the end of the spine. (Then they will understand why swimmers get scoliosis. They fall at the side of the pool probably when running.) This causes serious problems when the child is not fully developed.

Originally posted by MissEmmyF View PostI've actually read her memoir "Unwinding" which was quite interesting. I don't believe she ever exercised 4 hours a day...I think it was always only 1 hour per day (sometimes 2 hours, but that additional hour was running, not strengthening). It would be interesting to hear from her...
Martha described the training as "intensive." I don't think an hour a day would ever be considered intensive.

Could you expand on that? Did something like this happen to you or your child?
