经皮肌内功能性电刺激(P-FES)对脑性瘫痪(CP)患儿在步态过程中即刻改善踝关节运动学的可行性尚未见报道。8例脑性瘫痪患儿(双瘫6例，偏瘫2例；平均年龄9岁1个月[SD1Y4mo；7y11mo~11y10mo])经皮肌内电极植入患肢的腓肠肌(GA)和胫前肌(TA)。在三种情况下(仅GA、仅TA和GA/TA)，在步态周期的适当阶段提供刺激。在每种刺激条件下进行一周的练习后，立即进行有无刺激的步态分析。在GA/TA条件下，受累较重的患肢摆动时的最大背屈和受累较轻的患肢初次接触时的背屈均有明显改善。在仅TA和GA/TA条件下，对于受影响更多和更少的肢体，有明显的临床意义的趋势是背屈运动学的改善。结果提示，P-FES可立即改善脑性瘫痪患儿的踝关节运动学。
The feasibility of percutaneous intramuscular functional electrical stimulation (P-FES) in children with cerebral palsy (CP) for immediate improvement of ankle kinematics during gait has not previously been reported. Eight children with CP (six with diplegia, two with hemiplegia; mean age 9 years 1 month [SD 1y 4mo; range 7y 11mo to 11y 10mo]) had percutaneous intramuscular electrodes implanted into the gastrocnemius (GA) and tibialis anterior (TA) muscles of their involved limbs. Stimulation was provided during appropriate phases of the gait cycle in three conditions (GA only, TA only, and GA/TA). Immediately after a week of practice for each stimulation condition, a gait analysis was performed with and without stimulation. A significant improvement in peak dorsiflexion in swing for the more affected extremity and dorsiflexion at initial contact for the less affected extremity were found in the GA/TA condition. Clinically meaningful trends were evident for improvements in dorsiflexion kinematics for the more and less affected extremities in the TA only and GA/TA conditions. The results suggest that P-FES might immediately improve ankle kinematics in children with CP.
