Abstract

We measured torque curve pattern and quadriceps muscle strength with the knee slightly flexed in 48 patients with an anterior cruciate ligament injury, and analyzed the factors associated with reduced quadriceps strength. Strength was measured under isokinetic contraction, and concentric and eccentric contractions were studied. Strength was significantly lower in the injured knee, which also showed abnormal patterns of torque curve. In addition to the rapid downward slope pattern usually associated with concentric contraction, there was a concave pattern during eccentric contraction.

摘要

我们对48例前交叉韧带损伤患者在膝关节轻度屈曲时的扭矩曲线模式和股四头肌力量进行了测量,并分析了与股四头肌力量降低相关的因素。在等速收缩状态下测量力量,并研究向心收缩和离心收缩。受伤膝关节的力量明显较低,其扭矩曲线模式也异常。除了通常与向心收缩相关的快速下降斜率模式外,在离心收缩期间还出现了凹形模式。
