ABSTRACT
This study examined the relationship between multiple physical function and falls among institutionalized elderly women, and screening methods designed to effectively identify elderly with a high risk of falling. The subjects comprised 44 elderly women aged 82±6 years residing in a nursing home. Multiple physical assessments were tested using the following measures; muscle strength(quadriceps strength and grip strength), balance test(functional reach and one-legged stance test), flexibility test(sit and reach test), agility test(stepping test), and physical performance test(TUG and chair stand test). Based on the experience of fall-related accidents within the past two years, we categorized the subjects into two groups (non-fall group and fall group). Of these measures, quadriceps strength, grip strength, functional reach, stepping test in a standing position, and chair stand test were significant factors discriminating whether the subject had a history of falls. Logistic regression analysis demonstrated that quadriceps strength, functional reach, stepping test in a standing position, and chair stand test were important predictors of falls in an institutionalized elderly population. The results of this study suggest that 0.84 Nm/kg for quadriceps strength, 26 cm for functional reach, 17 steps for stepping test, and 14 sec for chair stand test, were useful indicators for screening institutionalized elderly for risk of falling. Particularly, the stepping test was most effective in screening the elderly to assess their fall risk.
