The primary objective of the present study was to compare the effect of a neoprene sleeve on knee joint position sense during a sitting open kinetic chain test and a supine closed kinetic chain test. Young (24 +/- 2 years old), healthy subjects (18 men and 18 women) performed knee joint angle replication tests during open kinetic chain knee extension (sitting) and closed kinetic chain leg press (supine with an axial load of 15% body weight) before and after application of a neoprene sleeve over the dominant knee. The improvement in ability to replicate joint angles after application of the sleeve (sleeve effect) was significantly less during the supine closed kinetic chain test (0.3 degree +/- 1.4 degrees) than during the sitting open kinetic chain test (1.2 degrees +/- 1.1 degrees). The sleeve effect was inversely related to subjects' performance without the sleeve during both the sitting open kinetic chain and supine closed kinetic chain tests, suggesting that some people may derive greater benefit from the sleeve than others. Although the sleeve effects were small, particularly during the supine closed kinetic chain test, 72% of subjects felt that the sleeve improved their overall test performance. Future research is needed to establish the functional relevance of the small sleeve effects observed and to identify the characteristics of people who might derive greatest benefit from sleeve use.
本研究的主要目的是比较氯丁橡胶护膝在坐姿开放动力链试验和仰卧位闭合动力链试验中对膝关节位置觉的影响。年轻（24±2岁）、健康的受试者（18名男性和18名女性）在优势膝关节佩戴氯丁橡胶护膝前后，分别进行了开放动力链膝关节伸展（坐姿）和闭合动力链腿举（仰卧位，轴向负荷为体重的15%）的膝关节角度复制试验。佩戴护膝后复制关节角度能力的改善（护膝效应）在仰卧位闭合动力链试验（0.3°±1.4°）中显著小于坐姿开放动力链试验（1.2°±1.1°）。在坐姿开放动力链试验和仰卧位闭合动力链试验中，护膝效应均与受试者不佩戴护膝时的表现呈负相关，这表明有些人可能比其他人从护膝中获益更多。尽管护膝效应较小，尤其是在仰卧位闭合动力链试验中，但72%的受试者认为护膝改善了他们的整体测试表现。未来需要开展研究，以确定所观察到的小幅度护膝效应的功能相关性，并确定可能从使用护膝中获益最大的人群特征。
