目的
探讨在膝关节僵硬步态行走的慢性卒中幸存者中，对腘绳肌进行功能性电刺激是否能改善膝关节运动学。
设计
准实验性的。
科目
16名成年慢性中风幸存者。
方法
幸存者接受功能性电刺激的腿筋，每周3次，持续1小时，为期5周。在训练前和训练5周后计算3D运动学。训练前无刺激行走的膝关节运动学与训练5周后有刺激行走的膝关节运动学进行比较。（干预效果）。此外，将训练期前无刺激行走的膝关节运动学与训练期后无刺激行走的膝关节运动学进行比较（治疗效果）。
结果
干预效果显示膝关节屈曲峰值显著增加，平均8.7°（标准差（SD）8.3，p = 0.001）。治疗效果显示膝关节屈曲峰值显著增加，平均3.1°（SD 4.7，p = 0.021）。结论：本探索性研究的结果表明，在以膝关节僵硬步态行走的卒中幸存者中，对腘绳肌进行功能性电刺激后，摆动时膝关节运动学增加。当参与者在腿筋刺激下行走时，在摆动中膝关节屈曲峰值的改善最大。低神经损伤的参与者对腘绳肌刺激的反应更好，并且有迹象表明，腘绳肌刺激的效果可以在单次治疗中预测。功能性电刺激的效果与更具侵入性的治疗方案（如肉毒杆菌毒素或软组织手术）相当。这使得功能性电刺激成为日常临床实践的可行治疗选择。
OBJECTIVE
To explore whether functional electrical stimulation of the hamstrings results in improved knee kinematics in chronic stroke survivors walking with a stiff knee gait.
DESIGN
Quasi-experimental.
SUBJECTS
Sixteen adult chronic stroke survivors.
METHODS
Survivors received functional electrical stimulation of the hamstrings, 3 times a week for 1 h during a period of 5 weeks. 3D kinematics was calculated before the training period and after 5 weeks of training. Knee kinematics of walking without stimulation before the training period was compared with walking with stimulation after 5 weeks of training. (intervention effect). In addition, knee kinematics of walking without stimulation before the training period was compared with walking without stimulation after the training period (therapeutic effect).
RESULTS
The intervention effect showed a significant increase, of mean 8.7° (standard deviation (SD) 8.3, p = 0.001), in peak knee flexion. The therapeutic effect showed a significant increase in peak knee flexion, of mean 3.1° (SD 4.7, p = 0.021) Conclusion: The results of this exploratory study suggest an increase in knee kinematics in swing after functional electrical stimulation of the hamstrings in stroke survivors walking with a stiff knee gait. The largest improvement in peak knee flexion in swing was seen when participants walked with hamstring stimulation. Participants with low neurological impairment responded better to hamstring stimulation, and there are indications that the effect of hamstring stimulation can be predicted during a single session. The effect of functional electrical stimulation is comparable to that of more invasive treatment options, such as botulinum toxin or soft-tissue surgery. This makes functional electrical stimulation a feasible treatment option for daily clinical practice.
