Effects of a Long-Term Supervised Schroth Exercise Program on the Severity of Scoliosis and Quality of Life in Individuals with Adolescent Idiopathic Scoliosis: A Randomized Clinical Trial Study.

Bracing is the standard approach for adolescent idiopathic scoliosis, a spinal curvature and rotation that develops during growth, but questions remain about whether adding structured exercise improves outcomes further. This trial compared adolescents who wore a brace plus a supervised Schroth exercise program three times a week for 12 months against those who wore a brace alone, following them for 18 months in total. The exercise-plus-brace group showed statistically significant improvements in the main spinal curve angle (Cobb angle), the degree of trunk rotation, and quality of life scores compared to the brace-only group at 12 months, with the rotation and quality of life differences still present 6 months later. However, the overall sum of curve angles did not differ significantly between groups.

The findings are interesting because they suggest a longer exercise program may add benefit beyond bracing alone, but this is a single trial and the effect sizes for some outcomes were modest, so the results need replication before drawing firm conclusions.

If you or your child has adolescent idiopathic scoliosis, a curved and rotated spine that shows up during the teenage growth years, bracing is often the main treatment offered. This study looked at whether adding a year of supervised Schroth exercises, done three times a week, to bracing made a difference compared to bracing on its own. After 12 months, teens doing the exercise program alongside their brace showed statistically significant improvements in their spinal curve angle, the amount their trunk was rotated, and how they rated their quality of life, compared to those using only a brace.

The improvements in trunk rotation and quality of life were still present six months after the program ended. One measure, the total of all curve angles combined, did not show a significant difference between the groups. This is a single trial, so while the results are promising for the idea that long-term supervised exercise adds something beyond bracing alone, more research would help confirm how reliable and lasting these benefits are.

This randomised controlled trial (n=80) compared a 12-month supervised Schroth exercise program combined with bracing against bracing alone in adolescents aged 10-17 with idiopathic scoliosis, assessing outcomes at baseline, 12 months, and 18 months (6 months post-intervention) using MANCOVA. At 12 months, the intervention group showed statistically significant between-group improvements in Cobb angle (mean difference -3.65°, 95% CI -5.81 to -1.53, p<0.001, Cohen's d=0.30, a small effect), maximum angle of trunk rotation (-3.05°, 95% CI -3.86 to -2.23, p<0.001, d=0.74, a moderate-to-large effect), and SRS-22 quality of life score (0.87, 95% CI 0.60 to 1.13, p<0.001, d=0.58, a moderate effect). Trunk rotation and quality of life differences persisted at 18 months, while no significant between-group difference emerged for the sum of curves outcome. The authors interpret these results as supporting a dose-response relationship favouring longer exercise duration, but this rests on a single trial with a modest sample size and one negative secondary outcome, limiting generalisability.

The Cobb angle effect size, while statistically significant, was small, so clinical importance should be weighed against the study's own reported measures rather than assumed.
