One hundred and thirty-three curves in 102 patients who were followed for an average of 40.5 years were evaluated to quantitate curve progression after skeletal maturity and for prognostic factors leading to curve progression. Sixty-eight per cent of the curves progressed after skeletal maturity.
In general, curves that were less than 30 degrees at skeletal maturity tended not to progress regardless of curve pattern. In thoracic curves the Cobb angle, apical vertebral rotation, and the Mehta angle were important prognostic factors. In lumbar curves the degree of apical vertebral rotation, the Cobb angle, the direction of the curve, and the relationship of the fifth lumbar vertebra to the intercrest line were of prognostic value.
Translatory shifts played an important role in curve progression. Curves that measured between 50 and 75 degrees at skeletal maturity, particularly thoracic curves, progressed the most.
Our findings suggest that a rehabilitation programme including active self-correction, task-oriented exercises and education carried out until skeletal maturity is useful in reducing the course of spinal deformity and improving HRQL in adolescents with mild AIS. We recommend its use in secondary care settings in which the staff are ade- quately trained in managing AIS.
According to the results of this study the Schroth exercise program applied in the clinic under physiotherapist supervision was superior to the home exercise and control groups; additionally, we observed that scoliosis progressed in the control group, which received no treatment.
Study showing the effect of a Schroth exercise supervised program and home exercise program on patients with scoliosis:
Supervised Schroth exercises provided added benefit to the standard of care by improving SRS-22r pain, self-image scores and BME. Given the high prevalence of ceiling effects on SRS-22r and SAQ questionnaires’ domains, we hypothesize that in the AIS population receiving conservative treatments, different QOL questionnaires with adequate responsiveness are needed.

Schroth technique positively influenced the Cobb angle, vital capacity, strength and postural defects in outpatient adolescents.

Weiss HR. The effect of an exercise program on VC and rib mobility in patients with IS. Spine. 1991;16:88–93.
The average increase in chest expansion was more than 20% in all groups at all measuring points. These findings show that a course of inpatient treatment by the Schroth method can lead to an increase in vital capacity and chest expansion so that, even in adult scoliosis patients, effective treatment of the associated restrictive ventilatory disorder is possible.

Study showing the effect of the Schroth Best Practice program in regards to spinal curve and trunk improvements and out-patients programs seems to provide better results than in-patient rehabilitation:
Lee SG. Improvement of curvature and deformity in a sample of patients with Idiopathic Scoliosis with specific exercises. OA Musculoskeletal Medicine. 2014; Mar 12;2(1):6.
The Scoliologic ‘Best Practice’ program is highly effective with respect to improvements of spinal curves and trunk deformity.
Curvatures exceeding 30° show better results than smaller curvatures.
The out-patient Scoliologic ‘Best Practice’ program seems to provide better results than intensive in- patient rehabilitation using the old Schroth standard still in use today.
In phases of little growth or in the outgrown patient this program can be used as the sole form of treatment.
In phases of high growth velocity bracing is indicated primarily. Here this program is used as an adjunct to bracing regularly.

Borysov M, Borysov A. Scoliosis short-term rehabilitation (SSTR) according to ‘Best Practice’ standards – are the results repeatable? Scoliosis. 2012 Jan 17;7(1):1.7.
Out-patient rehabilitation following the Scoliologic (TM) ‚Best Practice’ standards seems to provide an improvement of signs and symptoms of scoliosis patients in this study using a pre-/post prospective design. The results of the pilot study therefore seem to be repeatable.

BRACE DOSE–RESPONSE RELATIONSHIP
The majority of patients assigned to bracing (68%) were treated with a customized Boston-type thora- columbosacral orthosis. Temperature data were available for 116 patients (from both the random- ized and preference cohorts). During the first 6 months, patients wore the brace for a mean (±SD) of 12.1±6.5 hours per day (range, 0 to 23.0). The quartile of duration of brace wear was positively associated with the rate of success (P<0.001). The lowest quartile of wear (mean hours per day, 0 to 6.0) was associated with a success rate (41%) sim- ilar to that in the observation group in the pri- mary analysis (48%), whereas brace wear for an average of at least 12.9 hours per day was associated with success rates of 90 to 93% (Fig. 2).
Bracing significantly decreased the progression of high-risk curves to the threshold for surgery in patients with adolescent idiopathic scoliosis. The benefit increased with longer hours of brace wear.
Vigtigheden af bæretid i korset er allerede belyst i dette studie fra 1997:
We found that use of the Milwaukee brace or another thoracolumbosacral orthosis for twenty-three hours per day effectively halted progression of the curve. Bracing for eight or sixteen hours per day was found to be significantly less effective than bracing for twenty-three hours per day
Studie omkring vigtigheden af korrektion i korsettet samt bæretid for slutresultatet:
Compliant patients with a high initial correction can expect a final correction of around 7 degrees, while compliant patients with low initial correction may maintain the curve extent. Bad compliance is always associated with curve progression.
According to survivorship analysis, treatment with a brace was associated with a success rate of 74 per cent (95 per cent confidence interval, 52 to 84) at four years; observation only, with a success rate of 34 per cent (95 per cent confidence interval, 16 to 49); and electrical stimulation, with a success rate of 33 per cent (95 per cent confidence interval, 12 to 60)
At the end of treatment we observed an improvement in correction around at 23% from the beginning curves, and after 5 years there was stabilization at approximately 15%). Our results demonstrate that conservative treatment with the Cheneau brace is corrective for the treatment of Idiopathic Scoliosis (IS).
Rate of surgery can be reduced with the help of Chêneau braces of the latest standard and satisfactory in-brace correction. Brace treatment with the Chêneau brace seems effective and therefore clearly is indicated. Clinical outcomes may be more important for the patient than radiologic outcomes.
The results achieved with the GBW are significantly and better than the results achieved with the Boston brace. Therefore, the standards for bracing should be reviewed with the results that symmetric compression with Boston bracing is not as successful, when compared to asymmetric high correction bracing results, which allow a standardized classification-based corrective approach.
Conservative brace treatment using the Gensingen brace was successful in 92% of cases of patients with AIS of 40 degrees and higher. This is a significant improvement compared to the results attained in the BrAIST study (72%). Reduction of the ATR shows that postural improvement is also possible.
