The carry-over effect of gait-synchronized stimulation of the peroneal nerve on voluntary dorsiflexion of the paretic foot was evaluated in hemiplegic patients. The influence of providing audiovisual feedback of performance on voluntary control was also evaluated. Each patient received three test sessions separated at least one week apart. In each session, measurement of isometric torque from voluntary effort was repeated four times: before, and at 0, 30 and 60 minutes after a 20-minute walk period. Session 2 involved both peroneal stimulation during walking and performance feedback during voluntary efforts. Session 1 had stimulation only. Session 3 had feedback only. The results were inconsistent among the patients. Where increase of voluntary dorsiflexion was obtained, it was more a consequence of performance feedback than peroneal stimulation. General problems of using isometric torque produced by voluntary dorsiflexion as a measure of the carry-over effect are discussed.
在偏瘫患者中评估了腓总神经步态同步刺激对患侧足背屈自主控制的延迟效应。还评估了提供运动表现视听反馈对自主控制的影响。每位患者接受了至少间隔一周的三次测试。在每次测试中，对自主用力产生的等长扭矩进行测量，在20分钟步行期之前、之后0、30和60分钟各重复测量一次。测试2包括步行期间的腓总神经刺激和自主用力期间的运动表现反馈。测试1仅进行刺激。测试3仅进行反馈。患者之间的结果并不一致。在获得自主背屈增加的情况下，更多是运动表现反馈的结果而非腓总神经刺激的结果。讨论了使用自主背屈产生的等长扭矩作为延迟效应测量指标的一般问题。
