Abstract:[Objective] To evaluate the clinical efficacy of a new brace for correction of adolescent idiopathic scoliosis. [Methods] FromOctober 2021 to January 2023, 52 children who were newly diagnosed of adolescent idiopathic scoliosis, were included in this study and di-vided into two groups by randomized number table method. Of them, 26 patients were treated with the new brace (the NB group), while other26 patients were treated with the traditional brace (the TB group). The clinical and imaging data of the two groups were compared. [Results]Compared with those before treatment, the body height and SRS-22 scores in both groups were significantly increased 12 months after treat-ment (P＜0.05). At 12 months after treatment, the NB group proved significantly better than the TB group regarding SRS-22 scores [(90.3±8.8) vs (82.1±4.7), P＜0.001]. As for imaging, Cobb angle and apical translation (AT) of main curve were significantly decreased in bothgroups immediately after wearing the brace and 12 months after treatment compared with those before treatment (P＜0.05). The NB group wassignificantly superior to the TB group in terms of Cobb angle immediately after wearing brace and 12 months after treatment [(5.6±3.6)° vs(8.1±4.7)°, P=0.041; (10.1±8.5)° vs (13.4±6.5)°, P=0.032], and AT 12 months after treatment [(7.9±7.7) mm vs (11.3±5.8) mm, P=0.029]. Inaddition, the NB group was also significantly superior to the TB group in terms of immediate correction rate [(78.1±10.2)% vs (65.0±11.2)%,P=0.035) and the final correction rate [(64.3±15.2)% vs (44.5±14.3)%, P=0.004]. [Conclusion] Both kinds of braces are effective in the cor-rection of adolescent idiopathic scoliosis. By contrast, the new brace had considerably better correction efficiency, with better quality of lifeof the patients over the the traditional brace.
