Following a transfemoral amputation (TFA), numerous changes in movement patterns during gait can occur. Frontal plane hip and pelvis compensatory strategies are recognized among individuals with a TFA, some thought to aid in safe foot clearance during the swing phase of gait. The aim of this case study was to evaluate the effect of an active ankle dorsiflexion provided by a microprocessor-controlled prosthetic foot, as well as the effect of individualized training on these parameters. In this case study, a 42-year-old male underwent 3 D gait analysis. Data were captured for two conditions; with a microprocessor-controlled prosthetic foot with active/inactive ankle dorsiflexion, during two sessions; before and after 6 weeks of individualized training. The main outcomes analyzed were frontal plane pelvis and hip kinematics. Prior to training, pelvic lift decreased slightly, coupled with an increase in hip abduction, during gait with the active ankle dorsiflexion of a prosthetic foot, compared to inactive dorsiflexion. After the training period, the pelvic lift was further decreased and an increase in hip adduction was concurrently seen. The results of this case study indicate a positive effect of the active dorsiflexion of the prosthetic foot but highlight the need for specific training after prescription of a microprocessor prosthetic foot. Implications for rehabilitation Decreased compensatory changes seen in this case study indicate a positive effect of the active dorsiflexion of the prosthetic foot, especially after a 6-week training period. Individualized training should be aimed at helping the user utilizing the benefits of the active dorsiflexion of the microprocessor prosthetic foot, implementing exercises that improve gait quality, technical training for this specific foot, strength training and balance exercises.
经股截肢（TFA）后，步态中的运动模式可能会发生许多变化。TFA患者会采用额状面髋关节和骨盆的代偿策略，其中一些被认为有助于在步态摆动期安全地清除足部。本病例研究的目的是评估微处理器控制的假足提供的主动踝关节背屈的效果，以及个性化训练对这些参数的影响。在本病例研究中，一名42岁男性接受了三维步态分析。在两种情况下采集数据：分别使用具有主动/被动踝关节背屈功能的微处理器控制假足，在两个阶段进行采集，即在6周个性化训练前后。分析的主要结果是额状面骨盆和髋关节的运动学。在训练前，与被动背屈相比，在使用假足主动踝关节背屈的步态中，骨盆抬高略有下降，同时髋关节外展增加。训练期过后，骨盆抬高进一步下降，同时髋关节内收增加。本病例研究的结果表明假足主动背屈具有积极效果，但强调在开具微处理器假足处方后需要进行特定训练。康复意义本病例研究中观察到的代偿性变化减少表明假足主动背屈具有积极效果，尤其是在6周训练期之后。个性化训练应旨在帮助使用者利用微处理器假足主动背屈的益处，实施改善步态质量的练习、针对该特定假足的技术训练、力量训练和平衡练习。
