The aim of this work was to study movement control strategies in patients with knee arthritis. These strategies were expected to be different from healthy subjects because of deficiencies due to knee arthritis (i.e. pain, altered proprioception).
A kinetic and kinematic analysis was performed in a population of 10 patients with unilateral knee arthritis and in 11 age-matched control subjects, using an ELITE system and two AMTI force-plates. The different phases of a side step were studied.
The timing of the movement was different in the two populations. The postural phase was longer and the monopodal phase was shorter in knee arthritis patients when the affected leg was the supporting one than when the sound leg was supporting. Total step duration and landing-stabilization phase duration were longer in knee arthritis patients than in healthy subjects.
This movement analysis method enables to determine and to quantify differences between knee arthritis patients and control subjects. Clinical examination cannot identify these differences. Movement analysis methods bring up additional information to usual clinical evaluation scales and could be used for evaluation of the results of total knee arthroplasty.
本研究旨在探讨膝关节炎患者的运动控制策略。由于膝关节炎导致的功能缺陷（如疼痛、本体感觉改变），预计这些策略会与健康受试者不同。
使用ELITE系统和两个AMTI测力台，对10名单侧膝关节炎患者和11名年龄匹配的对照受试者进行了动力学和运动学分析。研究了侧步的不同阶段。
两组人群的运动时间不同。当患侧腿为支撑腿时，膝关节炎患者的姿势期较长，单足期较短，而健侧腿支撑时则相反。膝关节炎患者的总步长时间和着陆稳定期时间比健康受试者更长。
这种运动分析方法能够确定并量化膝关节炎患者与对照受试者之间的差异。临床检查无法识别这些差异。运动分析方法为常规临床评估量表提供了额外信息，可用于评估全膝关节置换术的效果。
