A systematic review was performed to summarize literature describing the test-retest reliability of grip strength measures obtained from older adults. Relevant literature was identified via a PubMed search. Seventeen articles were deemed appropriate based on inclusion and exclusion criteria. The relative test-retest reliability of grip strength measures obtained by dynamometry was good to excellent (intra-class correlation coefficients > 0.80) in all but 3 studies, which involved older adults with severe dementia. Absolute reliability, as indicated by summary statistics such as the minimum detectable change (95%), was more variable. As a percentage, that change ranged from 14.5% to 98.5%. Consequently, clinicians can be confident in the relative reliability of grip strength measures obtained from at risk older adults. However, relatively large percentage changes in grip strength may be necessary to conclude with confidence that a real change has occurred over time in some populations.
我们进行了一项系统综述，以总结描述从老年人获得的握力测量重测信度的文献。通过PubMed搜索确定了相关文献。根据纳入和排除标准，有17篇文章被认为是合适的。除了3项涉及患有严重痴呆症老年人的研究外，通过测力计获得的握力测量的相对重测信度在所有研究中都良好至优秀（组内相关系数>0.80）。如最小可检测变化（95%）等汇总统计数据所示，绝对信度的变化更大。该变化的百分比范围为14.5%至98.5%。因此，临床医生可以对从有风险的老年人获得的握力测量的相对信度充满信心。然而，在某些人群中，可能需要握力有相对较大的百分比变化，才能有信心地得出随着时间推移发生了真正变化的结论。
