Past research has reported a high level of correlation between peak torque (PT) and work and between PT and power in the muscles surrounding normal and selected pathological knees. No research to date has examined whether such similarities exist in clients with pathology to the medial compartment of the knee. The purpose of this study was to investigate the relationship between the isokinetic parameters of PT, work, and power for the flexor and extensor muscle groups of patients with grade I medial compartment knee sprains. Isokinetic data were collected from 77 patients (41 males, 36 females; mean age 24.6 yrs) on a Merac dynamometer at the speeds of 60, 180, 300, and 420 degrees /set. The ranges of Pearson correlations between PT and work and between PT and power were 0.75-0.96 for the involved knee flexors, 0.67-0.99 for the involved knee extensors, 0.76-0.98 for the uninvolved knee flexors, and 0.85-0.97 for the uninvolved knee extensor muscles. These findings suggest that PT is representative of work and power and may be the only necessary parameter for isokinetic muscle performance testing of the flexor and extensor muscles of the knee in clients with grade I medial compartment sprain.

过去的研究已经报告了正常和选定的病理膝关节周围肌肉的峰值扭矩（PT）与功和功率之间的高度相关性。迄今为止，尚无研究检查这种相似性是否存在于膝关节内侧室病变的患者中。本研究的目的是调查 I 级内侧间室膝关节扭伤患者屈肌和伸肌肌群等速参数 PT、功和功率之间的关系。使用 Merac 测力计在 60、180、300 和 420°/s 的速度下从 77 名患者（41 名男性，36 名女性；平均年龄 24.6 岁）中收集等速数据。患侧膝关节屈肌的 PT 与功和 PT 与功率之间的 Pearson 相关系数范围为 0.75-0.96，患侧膝关节伸肌为 0.67-0.99，健侧膝关节屈肌为 0.76-0.98，健侧膝关节伸肌为 0.85-0.97。这些发现表明 PT 代表功和功率，并且可能是 I 级内侧间室扭伤患者膝关节屈肌和伸肌等速肌肉性能测试的唯一必要参数。J Orthop Sports Phys Ther 1992;16(6):288-292.
