Pedometer accuracy in nursing home and community-dwelling older adults.

摘要: CYARTO, E. V., A. M. MYERS, and C. TUDOR-LOCKE. Pedometer Accuracy in Nursing Home Community-Dwelling Older Adults. Med. Sci. Sports Exerc., Vol. 36, No. 2, pp. 205–209, 2004. Purpose: The accuracy of pedometers has not been thoroughly tested with older adult populations. purpose the present study was to examine effects walking speed gait disorders on Yamax nursing home residents (NH) relative adults living community. Methods: evaluated against observed steps taken during a self-paced test (slow, normal, fast speeds) 26 NH 28 seniors’ recreation center members (SC). Devices were attached clothing at waist. Walking ascertained from timed walk assessment conducted. Percent error calculated as ([pedometer steps]/observed steps) 100. Results: speeds both samples increased across self-selected paces (P 0.0001). community-dwelling walked significantly faster 0.0001) all trials had higher ( P scores (indicating fewer problems). Gait positively associated pedometer percent error. Pedometers underestimated residents’ by 74% (slow), 55% (normal), 46% (fast) In SC sample, instruments failed detect 25%, 13%, 7% actual taken, respectively magnitude greater for versus trials. Conclusions: Slow hamper utility physical activity measurement frail seniors, such residents, when worn usual attachment site. Pedometers, however, can be confidently used ostensibly healthy populations motivation purposes. Key Words: MOTION SENSORS, PHYSICAL ACTIVITY MEASUREMENT, GAIT SPEED, DISORDERS, FRAIL POPULATION
