The telemetered electromyographic (EMG) activity of quadriceps, hamstrings, triceps surae and pretibial muscles on the affected side of 20 adult hemiplegic subjects was examined during locomotion. The subjects ranged in age from 29 to 68 years (mean, 52.1). Duration of the lesions ranged from 1 month to 8 years: in 11 subjects the duration of the lesions ranged from 1 to 9 months (mean, 4.9 months), and in the remaining 9 subjects from 1 to 8 years (mean, 4 years 2 months). Shoes with five microswitches, two in the heel and three in the sole, were used to correlate the EMG activity with eight specific components of the gait cycle. The results of the study showed a loss of the phasic pattern associated with normal locomotion. The hemiplegic subjects showed the greatest activity in the period of midstance. Expressed as a percentage of the total cycle, the mean stance time of the paretic lower limb was 67% and the mean swing time was 33%. The unaffected lower limb showed a stance phase of 80% and a swing phase of 20%.
对20名成年偏瘫患者患侧的股四头肌、腘绳肌、小腿三头肌和胫前肌的遥测肌电图（EMG）活动在运动过程中进行了检查。受试者年龄在29岁至68岁之间（平均52.1岁）。损伤持续时间从1个月至8年不等：11名受试者的损伤持续时间为1至9个月（平均4.9个月），其余9名受试者为1至8年（平均4年2个月）。使用带有五个微动开关的鞋子，其中两个在脚跟，三个在鞋底，将肌电图活动与步态周期的八个特定组成部分相关联。研究结果显示与正常运动相关的相位模式丧失。偏瘫患者在支撑中期的活动最为明显。以整个周期的百分比表示，患侧下肢的平均支撑时间为67%，平均摆动时间为33%。未受影响的下肢支撑期为80%，摆动期为20%。
