This study investigated the influence of orthoses, regular passive stretching, and surgery on progression of equinus deformity in Duchenne muscular dystrophy. The extent of passive dorsiflexion on the right foot of ambulant and wheelchair-ambulatory patients was measured monthly with an electronic ankle goniometer calibrated to an accuracy of 1 degree. The mean rate of equinus progression was 0.4 degree per month during the 12-month study. Progression was less in those boys who had prior surgery and were older. Progression was slowest during the first five months of the study (when night splints were used more frequently) and greatest during a long vacation when regular passive stretching by physiotherapists and supervision of splinting were unavailable. These results, although based on a limited patient sample size, indicate that gains from use of orthoses and passive stretching can be lost in the absence of professional supervision.
本研究调查了矫形器、常规被动拉伸和手术对杜氏肌营养不良症马蹄足畸形进展的影响。使用校准精度为1度的电子踝测角仪，每月测量能行走和轮椅辅助行走患者右脚的被动背屈程度。在为期12个月的研究中，马蹄足进展的平均速率为每月0.4度。先前接受过手术且年龄较大的男孩进展较慢。在研究的前五个月（夜间夹板使用更频繁时）进展最慢，而在长假期间进展最快，此时物理治疗师的常规被动拉伸和夹板监督无法进行。这些结果虽然基于有限的患者样本量，但表明在缺乏专业监督的情况下，使用矫形器和被动拉伸所取得的效果可能会丧失。
