To evaluate the clinical efficacy of functional electrical stimulation (FES) therapy of the tibialis anterior (TA) muscle on gait restoration and enhancing motor recovery with stroke patients.
Thirty hemiparetic participants with spastic foot-drop impairments who were at least 3 months post-stroke were recruited from a rehabilitation institute and were assigned either to a control group or a FES group. Both the groups participated in a conventional stroke rehabilitation program for 60 min per day, 5 days a week, for 12-weeks. The FES group received the electrical stimulation to the TA muscle for correction of foot-drop.
Functional electric stimulation (FES) resulted in a 26.3% (p < 0.001) improvement of walking speed measured with 10-m walkway, whereas the improvement in the control group was only 11.5% (p < 0.01). The FES group also showed significantly greater improvements compared to control group in other gait parameters (e.g. cadence, step length), physiological cost index (PCI), ankle range of motion, spasticity of calf muscle, Fugl-Meyer scores, and the maximum value of the root mean square (RMS(max)), which reflects the capacity of the muscle output.
These findings suggest that, the FES therapy combined with conventional therapy treatment more effectively improves the walking ability and enhances the motor recovery when compared with conventional therapy alone in stroke survivors.
评估功能性电刺激(FES)治疗胫骨前肌(TA)对改善步态和促进脑卒中患者运动功能恢复的临床疗效。
30 名偏瘫伴有痉挛性足下垂的脑卒中患者,在脑卒中后至少 3 个月,从康复机构招募,分为对照组和 FES 组。两组均接受每天 60 分钟、每周 5 天、共 12 周的常规脑卒中康复方案。FES 组接受 TA 肌肉电刺激以纠正足下垂。
功能性电刺激(FES)使 10 米步行测试的步行速度提高了 26.3%(p<0.001),而对照组的改善仅为 11.5%(p<0.01)。FES 组在其他步态参数(如步频、步长)、生理成本指数(PCI)、踝关节活动范围、小腿肌肉痉挛、Fugl-Meyer 评分和均方根最大值(RMS(max))等方面的改善也明显优于对照组,RMS(max)反映了肌肉输出能力。
这些发现表明,与单纯常规治疗相比,FES 治疗联合常规治疗更有效地提高了脑卒中幸存者的步行能力,并促进了运动功能恢复。
