A Multicenter Randomized Controlled Trial to Compare the Effect of Schroth Exercises to Standard Care on Curve Characteristics, Posture, and Quality Of Life in Adolescents With Idiopathic Scoliosis

Secondary aims include: 1. To determine the effect of Schroth exercises at 6 months on secondary outcomes including quality-of-life, spinal appearance, objective posture and spinal muscle endurance measurements. 2. To determine the efficacy of 6 months of Schroth therapy offered to control participants after completing 6 months in the standard-of care group (using subjects as their own controls) and 3.

To determine if the effects of the 6 months supervised Schroth exercise program can be maintained after supervised therapy is terminated. At Hopital Ste-Justine, the effect of Global Postural Re-education will also be examined because Global Postural Re-education exercises were offered routinely to patients at that institution prior to the trial.
