The knee extension force of 50 patients was investigated using traditional manual muscle testing and hand-held dynamometry. The relationship between manual muscle test word scores and dynamometer force scores was determined using Kendall tau, as was the relationship between manual muscle test percentage scores and dynamometer scores expressed as a percentage of "normal." Percentage scores were also compared to determine if a significant difference existed. Manual muscle test scores and dynamometer test scores were significantly correlated (p less than .001). Percentage manual muscle test and dynamometer test scores were significantly different (p less than .001). These results suggest that the two procedures measure the same variable-strength. Manual muscle test percentage scores of knee extension may, however, overestimate the extent to which a patient is "normal."
使用传统手法肌力测试和手持式测力计对50名患者的膝关节伸展力进行了研究。使用肯德尔秩相关系数确定了手法肌力测试文字评分与测力计力量评分之间的关系，以及手法肌力测试百分比评分与以“正常”百分比表示的测力计评分之间的关系。还比较了百分比评分以确定是否存在显著差异。手法肌力测试评分与测力计测试评分显著相关（p小于0.001）。手法肌力测试百分比评分与测力计测试评分显著不同（p小于0.001）。这些结果表明，这两种方法测量的是同一变量——力量。然而，膝关节伸展的手法肌力测试百分比评分可能会高估患者“正常”的程度。
