ABSTRACT
@# ObjectiveTo examine the test-retest reliability and measurement error in using a Jamar dynamometer to determine grip strength for elder men. Methods40 elder men with a mean age of 82 years old volunteered to participate in this study. The grip strength was administered twice using a Jamar dynamometer by specially trained testers; subjects were re-tested at the same time of day a week later by the same testers. ResultsThe infraclass correlation coefficient(ICC) was 0.99. The standard error of measurement (SEM and SEM%) were 1.18~1.69 and 4.11%~6.41%. The smallest real difference (SRD and SRD%) were 3.27~4.68 and 11.39%~17.75%. The Bland-Altman analysis revealed no systematic errors between test and retest. ConclusionThe Jamar dynamometer is reliable and with acceptable measurement errors to determine grip strength for elder men.
