Therapeutic effects in ten hemiplegic patients and one paraparetic patient treated by multisite electric stimulation of gait were compared with effects in ten hemiplegic patients treated by standard rehabilitation methods after 2.6 months of extensive therapy. Average step length and gait velocity, ground reaction forces and their distribution under both feet, and crutch loading were measured; goniograms of joint angles, kinesiologic gait analysis, and EMG recordings from the main muscles used in ambulation and in standing, were made while patients in both groups walked without stimulation. Quantitative measurements before, during, at the end, and 8.4 months posttherapy were taken based on at least 40 strides per patient. The results for the stimulated group in midtherapy indicated faster recovery rates (3.15 times in step length and 2.25 times in gait velocity) than in the control group, and at the end of therapy the stimulated group had higher improvement levels (2.14 times in step length, 1.42 times in gait velocity, and 1.63 times in kinesiologic gait analysis). The differences between the two groups faded after 8.4 months without treatment, and some kinesiologic deficits reappeared, mostly those in the more distal muscle groups. These findings indicate a need for a simpler orthotic electric stimulation after multisite therapy in several cases. Immediate effects of the six-site stimulation were also considered for orthotic possibilities after the therapy.
将多部位步态电刺激治疗的10例偏瘫患者和1例截瘫患者的治疗效果，与采用标准康复方法治疗的10例偏瘫患者在进行2.6个月广泛治疗后的效果进行了比较。测量了平均步长和步态速度、地面反作用力及其在双足下的分布以及拐杖负荷；在两组患者无刺激行走时，绘制了关节角度的角度图、运动学步态分析以及行走和站立时主要肌肉的肌电图记录。基于每位患者至少40步，在治疗前、治疗期间、治疗结束时以及治疗后8.4个月进行了定量测量。治疗中期，刺激组的恢复速度（步长为3.15倍，步态速度为2.25倍）比对照组快，治疗结束时，刺激组的改善水平更高（步长为2.14倍，步态速度为1.42倍，运动学步态分析为1.63倍）。未经治疗8.4个月后，两组之间的差异消失，一些运动学缺陷再次出现，主要是远端肌肉群的缺陷。这些发现表明，在某些情况下，多部位治疗后需要一种更简单的矫形电刺激。还考虑了六点刺激的即时效果在治疗后用于矫形的可能性。
