Chronic ankle instability (CAI) is associated with kinematic changes in the lower extremity. Alterations in joint-coupling have been identified during gait in patients with CAI. Rehabilitation remains the gold-standard for clinical treatment of CAI but little is known on the effects of rehabilitation on joint-coupling variability. Wearable destabilisation devices have shown an increase in muscle activity during functional tasks and may be useful in rehabilitation. The purpose of this study is to analyse the joint-coupling variability during gait prior to and following a rehabilitation programme performed with and without destabilisation devices. Twenty-six individuals with CAI were randomly assigned to receive 4 weeks of comprehensive rehabilitation with or without destabilisation devices. A 3D motion capture system was used to collect kinematics during walking. A vector-coding analysis was used to assess the joint-coupling variability of knee and hip motion to ankle motion. The destabilisation device group had decreases in joint-coupling variability during periods of walking gait. This decrease in joint-coupling variability may represent a change in sensorimotor organisation following rehabilitation. This decrease is indicative of an adaptation to the rehabilitation using destabilisation devices and may indicate an improvement in sensorimotor function.
慢性踝关节不稳定（CAI）与下肢运动学变化有关。在 CAI 患者的步态中已经确定了关节耦合的改变。康复仍然是 CAI 临床治疗的金标准，但对于康复对关节耦合可变性的影响知之甚少。可穿戴式失稳装置在功能任务中显示出肌肉活动增加，可能对康复有用。本研究的目的是分析在使用和不使用失稳装置进行康复计划之前和之后步态中的关节耦合可变性。26 名 CAI 患者被随机分配接受 4 周的综合康复治疗，包括或不包括失稳装置。使用 3D 运动捕捉系统收集步行时的运动学。矢量编码分析用于评估膝关节和髋关节运动对踝关节运动的关节耦合可变性。失稳装置组在步行期间的关节耦合可变性降低。这种关节耦合可变性的降低可能代表康复后感觉运动组织的改变。这种关节耦合可变性的降低表明使用失稳装置进行康复的适应性，并且可能表明感觉运动功能的改善。
