Popis:	Purpose This study examined the accuracy and consistency of hand-held dynamometer (HHD) in assessing leg muscle strength in older adults. Methods Forty-eight elderly men and women (12 males and 36 females), aged 60-85 years, were recruited for this study. All study participants had anthropometric measurements, handgrip, the HHD, and isokinetic dynamometer tests. Pearson partial correlations were used to examine the validity of HHD compared with an isokinetic dynamometer after adjustment for age, sex, and race. Cronbach α coefficients were used to estimate the test-retest reliability of the HHD measurement. Results Age-, sex-, and race-adjusted partial Pearson correlation coefficients were 0.90 for isometric leg strength (p < 0.001), 0.62 for isokinetic leg strength (p < 0.001), and 0.63 for handgrip strength (p < 0.001) with the HHD. Cronbach α coefficients showed high interclass reliabilities in measuring leg muscle strength using the HHD in men (α=0.99) and women (α=0.96). Conclusions The HHD had good concurrent validity with high interclass reliability in assessing leg muscle strength in older adults.
