The purpose of this study was to identify changes in equilibrium and movement control strategies in patients with arthritis of the knee. These strategies were expected to be different from those of healthy subjects because of the impairments caused by knee arthritis. The different phases of a side step were studied in patients with severe knee arthritis using a movement analysis system and force-plates. The duration of the postural phase and the intensity of the horizontal ground reaction forces during the postural phase were increased when the pathological limb was the supporting one. The monopodal phase was shortened on the pathological leg. These results show that knee arthritis patients develop new posturomotor strategies mainly aimed at shortening the monopodal phase when the affected leg is the supporting one. This movement analysis method enables quantification of differences that cannot be observed on clinical examination between knee arthritis patients and control subjects, and provides additional information to the usual clinical evaluation scales.
本研究的目的是确定膝关节炎患者平衡和运动控制策略的变化。由于膝关节炎造成的功能损害，预计这些策略会与健康受试者的不同。使用运动分析系统和测力板，对重度膝关节炎患者侧步的不同阶段进行了研究。当患侧肢体作为支撑腿时，姿势期的持续时间以及姿势期水平地面反作用力的强度会增加。患侧腿的单足支撑期缩短。这些结果表明，膝关节炎患者会形成新的姿势运动策略，主要目的是在患侧腿作为支撑腿时缩短单足支撑期。这种运动分析方法能够量化膝关节炎患者与对照受试者在临床检查中无法观察到的差异，并为常用的临床评估量表提供额外信息。
