Falls are a major concern in the elderly population with chronic joint disease. To compare muscular function and functional mobility among older women with knee osteoarthritis with and without a history of falls, 15 elderly women with a history of falls (74.20 +/- 4.46 years) and 15 without a history of falls (71.73 +/- 4.73 years) were studied. Muscular function, at the angular speed of 60, 120, and 180 masculine/s, was evaluated using the Biodex Isokinetic Dynamometer. The sit-to-stand task was performed using the Balance Master System and the Timed Up and Go test was used to determine functional mobility. After collection of these data, the history of falls was investigated. A statistically significant difference was detected in the time taken to transfer the center of gravity during the sit-to-stand test (means +/- SD; non-fallers: 0.35 +/- 0.16 s; fallers: 0.55 +/- 0.32 s; P = 0.049, Student t-test) and in the Timed Up and Go test (medians; non-fallers: 10.08 s; fallers: 11.59 s; P = 0.038, Mann-Whitney U-test). The results indicated that elderly osteoarthritic women with a history of falls presented altered functional mobility and needed more time to transfer the center of gravity in the sit-to-stand test. It is important to implement strategies to guarantee a better functional performance of elderly patients to reduce fall risks.
跌倒在患有慢性关节疾病的老年人群中是一个主要问题。为了比较有跌倒史和无跌倒史的老年膝骨关节炎女性之间的肌肉功能和功能活动能力，对15名有跌倒史的老年女性（74.20±4.46岁）和15名无跌倒史的老年女性（71.73±4.73岁）进行了研究。使用Biodex等速测力计在60、120和180度/秒的角速度下评估肌肉功能。使用平衡大师系统进行从坐到站的任务，并使用定时起立行走测试来确定功能活动能力。收集这些数据后，调查跌倒史。在从坐到站测试中转移重心所需的时间（平均值±标准差；未跌倒者：0.35±0.16秒；跌倒者：0.55±0.32秒；P = 0.049，学生t检验）以及定时起立行走测试（中位数；未跌倒者：10.08秒；跌倒者：11.59秒；P = 0.038，曼-惠特尼U检验）中检测到统计学上的显著差异。结果表明，有跌倒史的老年骨关节炎女性功能活动能力改变，在从坐到站测试中转移重心需要更多时间。实施策略以保证老年患者有更好的功能表现以降低跌倒风险很重要。
