: The purpose of this study was to demonstrate to what extent ankle-foot orthoses improve posture and gait control in patients with Charcot-Marie-Tooth disease and to identify the most appropriate characteristics of ankle-foot orthoses for patients regarding their clinical characteristics.
: Twenty-six Charcot-Marie-Tooth patients were recruited. Clinical data (such as levels of sensory and muscular deficits) and posture and gait capacities were collected in three randomized experimental conditions (wearing ordinary shoes or with plastic and elastic orthoses). Several subgroups of patients, constituted using predictive value analysis, were associated using the probabilities of enhancing posture and gait control while wearing the various models of orthoses.
: Compared with ordinary shoes alone, adding plastic ankle-foot orthoses partially improved both gait and posture control, whereas wearing elastic orthoses only partially affected the more dynamic gait control. Furthermore, the choice between the two models can be clarified by taking into account distal lower limb muscle capacity.
: Ankle-foot orthosis prescription appears relevant for improving balance and gait performance in Charcot-Marie-Tooth patients, particularly when the model adequately compensates for specific muscle deficits. This study also provides objective arguments for making adequate bracing.
本研究旨在展示踝足矫形器在改善 Charcot-Marie-Tooth 病患者姿势和步态控制方面的效果，并确定最适合患者临床特征的踝足矫形器特征。
共招募了 26 名 Charcot-Marie-Tooth 患者。在三种随机实验条件下（穿普通鞋或塑料和弹性矫形器）收集了临床数据（如感觉和肌肉缺损程度）和姿势及步态能力。使用预测值分析构建了几个亚组患者，并使用穿着不同类型矫形器时增强姿势和步态控制的概率来关联。
与单独穿普通鞋相比，添加塑料踝足矫形器可部分改善步态和姿势控制，而仅穿弹性矫形器则仅部分影响更动态的步态控制。此外，通过考虑下肢远端肌肉能力，可以阐明两种模型之间的选择。
踝足矫形器处方对于改善 Charcot-Marie-Tooth 病患者的平衡和步态表现是合理的，特别是当模型充分补偿特定的肌肉缺陷时。本研究还为进行适当的支具治疗提供了客观依据。
