Abstract: | BACKGROUND: Stooping, crouching, and kneeling (SCK) are fundamental components of daily living tasks, and nearly a quarter of older adults report a lot of difficulty or inability to perform these movements. This study examined characteristics associated with SCK difficulty to explore underlying mechanisms and remediation strategies. METHODS: One hundred eighty-four older adults with no, low, or high SCK difficulty underwent a comprehensive laboratory visit at the University of Michigan. RESULTS: Twenty-one percent of participants (n = 39) reported a lot of difficulty or inability to stoop, crouch, or kneel. Characteristics independently associated with increasing SCK difficulty were self-reported leg joint limitations, (odds ratio OR] = 3.84; 95% confidence interval CI], 1.64-9.01), Activities-specific Balance Confidence Scale score (OR = 0.97; 95% CI, 0.95-0.99), and knee extension strength (OR = 0.72; 95% CI, 0.55-0.94). CONCLUSIONS: Increasing SCK difficulty is associated with balance confidence as well as leg limitations. Remediation of SCK difficulty will likely require a program that encompasses both behavioral and physical issues. |
