The purpose of this study was to determine and compare the balance, muscular strength, and flexibility of two groups of elderly adults: one with a history of falls (HF) and one with no history of falls (NHF). Subjects were 19 men and 36 women. Static and dynamic balance was determined by a one-foot stance balance test and a backwards walking test. Hip, knee, and ankle joint muscular strength were assessed on a Cybex Leg Press Dynamometer. A goniometer was used to determine hip, knee, and ankle joint range of motion (flexibility), ANOVA indicated a significant difference between the two groups for static balance (p less than .001), leg strength (p less than .01), and hip and ankle flexibility (p less than .01). The results suggest that balance, leg strength, and flexibility may be factors contributing to falls in the elderly.
本研究的目的是确定并比较两组老年人的平衡能力、肌肉力量和柔韧性：一组有跌倒史（HF），另一组无跌倒史（NHF）。受试者包括19名男性和36名女性。通过单脚站立平衡测试和向后行走测试来确定静态和动态平衡。使用Cybex腿部推举测力计评估髋、膝和踝关节的肌肉力量。使用测角器确定髋、膝和踝关节的活动范围（柔韧性），方差分析表明两组在静态平衡（p<0.001）、腿部力量（p<0.01）以及髋部和踝部柔韧性（p<0.01）方面存在显著差异。结果表明，平衡能力、腿部力量和柔韧性可能是导致老年人跌倒的因素。
