Inhibition of the non-weight-bearing quadriceps was studied in ten patients with chronic knee effusions. The muscles were tested with the knees both flexed and extended, before and after joint aspiration. More inhibition was seen when the knees were extended (p less than 0.005). There was no relationship between muscle inhibition and the size of effusion, pain experienced during contraction or the extent of weakness. Aspiration of joints did not reduce the amount of inhibition. Acute effusions have previously been shown to cause muscle inhibition, even when pain-free, and we suggest that the known changes in the compliance of chronically effused joints are responsible for the observed differences in the effect of acute and chronic effusions.
对10例慢性膝关节积液患者的非负重股四头肌抑制情况进行了研究。在关节穿刺前后，分别在膝关节屈曲和伸展状态下对肌肉进行测试。当膝关节伸展时，观察到更多的抑制现象（p<0.005）。肌肉抑制与积液大小、收缩时的疼痛体验或无力程度之间没有关系。关节穿刺并没有减少抑制程度。先前已表明，即使无痛，急性积液也会导致肌肉抑制，我们认为，慢性积液关节顺应性的已知变化是急性和慢性积液效果差异的原因。
