I measured the knee extension torque, produced by eight hemiparetic patients during repeated knee extension-flexion reversals and during separated knee extension-flexion dyads, to determine the effect of "reversal of antagonists" on knee extension torque. The hemiparesis in these eight patients was secondary to intracranial lesions. I tested their involved lower extremity on an isokinetic dynamometer at 60 degrees/sec. Using a sequential medical-trials design, I found knee extension torque to be significantly greater during repeated knee extension-flexion reversals than during separated knee extension-flexion dyads (p less than .05). I, therefore, concluded that reversal of antagonists may facilitate knee extension torque production in the type of patients tested, under the specific conditions of their testing.
我测量了八名偏瘫患者在反复进行膝关节屈伸转换以及在分开的膝关节屈伸二元组过程中产生的膝关节伸展扭矩，以确定“拮抗肌反转”对膝关节伸展扭矩的影响。这八名患者的偏瘫继发于颅内病变。我在等速测力计上以60度/秒的速度测试了他们受累的下肢。采用序贯医学试验设计，我发现反复进行膝关节屈伸转换时的膝关节伸展扭矩显著大于分开的膝关节屈伸二元组时的扭矩（p小于0.05）。因此，我得出结论，在测试的特定条件下，拮抗肌反转可能会促进所测试类型患者的膝关节伸展扭矩产生。
