Table 1. Demographic data and comparison of measurement parameters.

The values are given as the mean and the standard deviation.

Group A, 0° or more improvement of the rotation angle after the initial brace treatment; Group B, more than 0° deterioration of the rotation angle after the initial brace treatment.

^a)Improve rate was calculated using the following formula: (Cobb angle at pre-treatment–Cobb angle at initiation of bracing or at final follow-up)/Cobb angle at pre-treatment×100%; ^b)Differences of rotation angle was calculated using the following formula: rotation angle at pre-treatment–rotation angle at initiation of bracing or at final follow-up.
