摘要： 目的分析Jamar握力器在老年人握力测量时的重测信度和测量误差。方法40位老年志愿者，平均年龄（82.2±8.4）岁。接受间隔1周共2次Jamar握力器测量握力。结果组内相关系数为0.99。测量标准误（SEM、SEM%）为1.18～1.69、4.11%～6.41%；个案最小真实改善程度值（SRD、SRD%）为3.27～4.68、11.39%～17.75%；Bland-Altman分析显示没有系统误差。结论在老年男性中，Jamar握力器具有良好的重测信度与可接受的测量误差。

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.
