| Annotation | Previous research has established a consistent positive association between skeletal muscle strength and physical functioning, but several important limitations remain to be considered. This study uses cross-sectional data to examine the relationships among physiological impairments, functional limitations, and disability in a moderately disabled sample of 207 older Americans living in the community. As hypothesised, data revealed statistically significant curvilinear relationships of upper and lower extremity strength and balance with mobility in this older sample. Multivariate analyses further clarified the hypothesised causal mechanism among the disablement concepts by demonstrating that most of the association of muscle strength and balance with disability was through the intermediary role of mobility limitations. These findings highlight the value of clinical trials that focus on prevention or treatment of mobility limitations as a means of preventing disability. They also underscore the need for future research that examines the effects of other variables believed to influence disablement in later life. (RH). |
