The purpose of this investigation was to determine the relationship of torque developed by knee extensor muscles to torque developed by knee flexor muscles as a result of rehabilitation programs for patients with chondromalacia, ligamentous repairs, and meniscectomies. Peak torque of knee extensor and flexor muscles was measured at slow dynamic and rapid dynamic tension on the involved and homologous noninvolved limb. The rehabilitation program produced significant changes in the torque of the involved limb at both dynamic tensions for each group of patients. The knee extensor muscles of the involved limb were not rehabilitated to the level of the knee extensor muscles of the noninvolved limb were rehabilitated to the level of those of the noninvolved limb. The ratio of flexor to extensor muscle torque seemed dependent on the nature of the injury and the rate of displacement. The ratio of flexor to extensor muscle torque of the involved limb was not rehabilitated to that of the homologous noninvolved limb. In rehabilitating muscles of the knee, attention must be directed to the ration between the flexor and extensor muscle torque of the knee.
本研究的目的是确定软骨软化症、韧带修复和半月板切除术患者康复计划后，膝伸肌产生的扭矩与膝屈肌产生的扭矩之间的关系。在受累肢体和同源未受累肢体上，分别在慢速动态和快速动态张力下测量膝伸肌和屈肌的峰值扭矩。康复计划使每组患者受累肢体在两种动态张力下的扭矩都发生了显著变化。受累肢体的膝伸肌未恢复到未受累肢体膝伸肌的水平。屈肌与伸肌扭矩之比似乎取决于损伤的性质和位移速率。受累肢体的屈肌与伸肌扭矩之比未恢复到同源未受累肢体的水平。在膝关节肌肉康复过程中，必须关注膝关节屈肌和伸肌扭矩之间的比例。
