The fear of falling can have detrimental effects on physical function in the elderly population, but the relationship between a persons' confidence in the ability to maintain balance and actual balance ability and functional mobility is not known. The extent to which balance confidence can be explained by balance performance, functional mobility, and sociodemographic, psychosocial, and health-related factors was the focus of this study.
The subjects were 50 community-dwelling elderly people, aged 65 to 95 years (mean=81.7, SD=6.7).
Balance was measured using the Berg Balance Scale. Functional mobility was measured using the Timed Up Go Test. The Activities-specific Balance Scale was used to assess balance confidence. Data were analyzed using Pearson correlation, multiple regression analysis, and t tests.
Fifty-seven percent of the variance in balance confidence could be explained by balance performance. Functional mobility and subject characteristics examined in this study did not contribute to balance confidence.
Balance performance alone is a strong determinant of balance confidence in community-dwelling elderly people.
害怕跌倒会对老年人群的身体功能产生不利影响，但人们维持平衡能力的信心与实际平衡能力及功能活动能力之间的关系尚不清楚。本研究的重点是平衡能力表现、功能活动能力以及社会人口学、心理社会和健康相关因素能够在多大程度上解释平衡信心。
研究对象为50名年龄在65至95岁之间（平均年龄=81.7岁，标准差=6.7岁）的社区居住老年人。
使用伯格平衡量表测量平衡能力。使用定时起立行走测试测量功能活动能力。使用特定活动平衡量表评估平衡信心。采用Pearson相关性分析、多元回归分析和t检验对数据进行分析。
平衡信心57%的变异可由平衡能力表现来解释。本研究中所考察的功能活动能力和研究对象特征对平衡信心没有影响。
对于社区居住的老年人而言，仅平衡能力表现就是平衡信心的一个重要决定因素。
