探讨对侧控制神经肌肉电刺激（CCNMES）改善主动踝关节背屈功能的可行性。CCNMES背屈麻痹踝关节的刺激强度是直接成比例的程度，未受损的对侧踝关节的自主背屈，这是检测到的仪器袜子。3名患有慢性（卒中后>6个月）背屈肌轻瘫的受试者参加了为期6周的CCNMES治疗，包括每天在家进行CCNMES辅助踝关节背屈练习，每周两次在研究实验室进行踝关节运动控制任务。对于受试者1和2，最大自主踝关节背屈分别增加了13和17度，踝关节运动跟踪误差减少了约57%和57%，下肢Fugl-Meyer评分（最高评分为34）增加了4和5分。受试者3在这些指标方面没有明显改善。受试者1和受试者2在3个月随访期间保持了踝关节运动跟踪性能;受试者2也保持了踝关节最大背屈和Fugl-Meyer评分的增加。这些结果表明，CCNMES可能对一些中风幸存者的踝关节运动障碍有积极的影响。需要进一步研究CCNMES对步态的影响。
To evaluate the feasibility of improving active ankle dorsiflexion with contralaterally controlled neuromuscular electrical stimulation (CCNMES). CCNMES dorsiflexes the paretic ankle with a stimulation intensity that is directly proportional to the degree of voluntary dorsiflexion of the unimpaired contralateral ankle, which is detected by an instrumented sock. Three subjects with chronic (>6-mo poststroke) dorsiflexor paresis participated in a 6-wk CCNMES treatment, which consisted of self-administering CCNMES-assisted ankle dorsiflexion exercises at home daily and practicing an ankle motor control task in the research laboratory twice a week. For subjects 1 and 2, respectively, maximum voluntary ankle dorsiflexion increased by 13 and 17 degrees, ankle movement tracking error decreased by ~57% and 57%, and lower limb Fugl-Meyer score (maximum score is 34) increased by 4 and 5 points. Subject 3 had no appreciable improvement in these measures. Both subjects 1 and 2 maintained their performance in ankle movement tracking through the 3-mo follow-up; subject 2 also maintained the gains in maximum ankle dorsiflexion and Fugl-Meyer score. These results suggest that CCNMES may have a positive effect on ankle motor impairment in some stroke survivors. Further investigation of the effect of CCNMES on gait is warranted.
