I found a scoliosis forum
http://www.scoliosis.org/forum in which various nonsurgical treatments are discussed, including some mentioned in this thread. I found a few reports of success in achieving mild straightening of curvatures in young girls, but overall the patient reports re: nonsurgical treatments were not that encouraging.
I did find some interesting info re: minerals and scoliosis while quickly checking for any research I haven't seen before:
Changes of selenium, copper, and zinc content in hair and serum of patients with idiopathic scoliosis.
J Orthop Res. 2008 Sep;26(9):1279-82.
Dastych M, Cienciala J, Krbec M.
http://www.ncbi.nlm.nih.gov/pubmed/18404661High zinc and copper and low selenium were associated with scoliosis. Some animal studies have found both high zinc or selenium and low zinc or selenium to be associated with scoliosis. So maybe it's the balance of zinc, copper, selenium and other nutrients, rather than simple deficiency in one, that's a factor.
Idiopathic Scoliosis Nutritional Deficiencies
Dr. Stitzel
http://www.squidoo.com/scoliosis-nutrition"What researchers are finding is that the ratio of different minerals is more important than just a single mineral being high or low in the body. With larger more progressive scoliosis patients the ratio between copper and selenium was significantly different than control groups. This ratio was off by such a large degree because of both the elevated levels of copper and the deceased levels of selenium occurring at once. Selenium was found to be interlinked to a chemical known as osteopontin found in high levels with patients diagnosed with adolescent idiopathic scoliosis."
Scoliosis Affects the Entire Body
http://www.prcstudiocity.com/scoliosis.html"Nutritional Support: Some scoliosis patients are found to have specific patterns of nutritional and hormonal imbalances. These include depressed levels of essential trace minerals selenium, zinc, and iron as well as absorption problems. When a nutritional imbalance is suspected, the appropriate referral to a nutritionist is made."

Scoliosis: Exercise, Diet & Yoga Alternative Treatments
By Sandy Simmons
http://www.ctds.info/spinecurve.html"Scoliosis has been induced in a variety of animals through the creation of nutritional deficits and imbalances. Not surprisingly, many of the nutritional imbalances linked to scoliosis in animals such as deficits of manganese, vitamin B6, and copper have all also been implicated as factors in osteoporosis in humans. As noted above, research shows there are strong links between scoliosis and osteoporosis."
Because excessive selenium and copper have also been associated with scoliosis and other problems, I would caution people to be careful about trying copper and selenium supplements, particularly mega-dosing, and particularly if there aren't other symptoms of deficiency. I would think that getting one's nutrients as much as possible from foods would help avoid creating worse imbalances. Optimally, one would also get one's nutrient levels tested (
http://chriskresser.com/selenium-the-missing-link-for-treating-hypothyroidism#comment-13410), though I have read that many nutrient tests tend to be considered unreliable, poorly understood, or excessively expensive.
FWIW, over the years I tried various forms of chiropractic (and I think other methods were mixed in by at least one chiropractor), yoga, exercises, massage, acupressure, improved posture practices, Gokhale, Egoscue and probably other things I've forgotten, but the only thing I've noticed any long-lasting improvement from so far is dietary change, though evolutionarily-informed Gokhale-type practices like minimizing Western-style chair sitting and doing more squatting and standing instead do help improve my short-term comfort. The improvements from dietary change were apparent mild straightening of curvature with 1/2" increased height, gradually improving flexibility in formerly tight muscles, better balance, and less back pain after stressors like long car rides.
