OBJECTIVES
To compare balance in individuals with symptomatic knee osteoarthritis (OA) and in age-, gender- and body-mass-matched controls using simple clinical measures.
METHODS
Thirty-three people with OA and 33 controls participated. Static postural sway [antero-posterior (AP), lateral and total] was measured using a swaymeter on two different surfaces and under two visual conditions. Dynamic standing balance was assessed using the 'step test'.
RESULTS
Both groups displayed similar postural sway on most variables measured. Significantly greater sway was noted in the OA group on a firm surface in both lateral (eyes open) and AP directions (eyes closed), as well as total sway (eyes closed) (P < 0.05). Poorer dynamic standing balance was observed in the OA group as evidenced by the step test (P < 0.0001).
CONCLUSIONS
Balance deficits can be identified in the osteoarthritic population using simple, inexpensive measures. However, the clinical relevance of the small deficits identified remains unknown and warrants further investigation.
目的
采用简单的临床测量方法，比较有症状的膝关节骨关节炎（OA）患者与年龄、性别和体重匹配的对照组的平衡能力。
方法
33例OA患者和33名对照者参与研究。使用姿势摇摆仪在两种不同表面和两种视觉条件下测量静态姿势摇摆[前后（AP）、侧向和总体]。使用“阶梯试验”评估动态站立平衡。
结果
在大多数测量变量上，两组的姿势摇摆相似。在坚硬表面上，OA组在侧向（睁眼）和AP方向（闭眼）以及总体摇摆（闭眼）方面的摇摆明显更大（P<0.05）。阶梯试验表明，OA组的动态站立平衡较差（P<0.0001）。
结论
使用简单、廉价的测量方法可以在骨关节炎人群中识别出平衡缺陷。然而，所识别出的微小缺陷的临床相关性尚不清楚，值得进一步研究。
