Comparison of average Cobb angles between on initial brace wearing and in hanging position among Risser 0 or I, II or III, and IV or V. In the patients of Risser 0 or I, the average BA was smaller than the average HA. While, in the patients of Risser IV or V, the average HA was smaller than the average BA. The rate of BA < HA cases were decreased as the Risser stage of the patients were progressed. (BA: Cobb angle on initial brace wearing, HA: Cobb angle in hanging position).
