Abstract
Abstract Aims To present reference values, clinically significant changes (CSC), and prediction equations of lower-limb muscle strength (LMS) and physical performance (PP) in community-dwelling older adults in a rural area. Methods Quadriceps muscle and toe grip strength were measured as LMS. Maximal gait speed, Timed-Up and Go test, one-legged stand test, and four-square step test were measured as PP. Overall and age-specific reference values for both sexes were presented. CSC was calculated using a distribution-based approach. We conducted multivariate regression analyses to make prediction equations for each variable. The prediction error was checked using 10-fold cross-validation. Results Three-hundred ninety-two participants (male, n = 116; female, n = 276) were included. LMS was maintained with age, while PS declined linearly. The prediction equations were significant, but the prediction error was high. Conclusions Reference values and CSC help evaluate the deterioration of LMS and PP and the effectiveness of an intervention on these outcomes.
期刊介绍:
This comprehensive journal is recognized for its useful balance of research and clinical practice articles. For more than twenty five years Physical & Occupational Therapy in Geriatrics has functioned as a forum for allied health professionals as well as others with a focus on rehabilitation of the geriatric client to share information, clinical experience, research, and therapeutic practice. Each issue focuses on current practice and emerging issues in the care of the older client, including rehabilitation and long-term care in institutional and community settings, and innovative programming; the entire range of problems experienced by the elderly; and the current skills needed for working with older clients.
