The Cybex II isokinetic dynamometer was used to measure quadriceps femoris and hamstring muscle function in 15 patients with hemiparesis. Comparisons of isokinetic data obtained at 30 degrees/sec and 180 degrees/sec were made between the involved and uninvolved side of patients and the right side of 15 healthy subjects matched by age, sex, and weight. Peak torque of both muscles on both sides of the patients was significantly less than the peak torque of muscles of healthy subjects at both speeds. Other significant differences occurred on the involved side including decreased limb excursion, prolonged time factors related to tension development and the interval between reciprocal contractions, and fatigability at high speed. Results indicated that isokinetic testing can provide objective information about quadriceps femoris and hamstring muscle performance in hemiparetic patients.
使用Cybex II等速测力计对15例偏瘫患者的股四头肌和腘绳肌功能进行测量。将患者患侧与健侧以及15名年龄、性别和体重匹配的健康受试者右侧在30度/秒和180度/秒时获得的等速数据进行比较。患者两侧肌肉的峰值扭矩在两种速度下均显著低于健康受试者肌肉的峰值扭矩。患侧还出现了其他显著差异，包括肢体运动幅度减小、与张力发展和往复收缩间隔相关的时间因素延长以及高速时的易疲劳性。结果表明，等速测试可以提供有关偏瘫患者股四头肌和腘绳肌性能的客观信息。
