The purpose of this study was to determine which setting of the clinical dynamometer produced maximal grip strength and to correlate that setting with characteristics of the individual. Using a computerized isometric dynamometer, the maximal grip strength was determined in 288 normal asymptomatic hands in 4- to 78-year-old individuals at five dynamometer size settings. The majority of hands (256, or 89%) had a maximal grip strength at setting II. Mean body weight and mean height were lower in the group that had a maximal strength at or equal to setting I than in those individuals with maximal setting II and above. However, no clear significant correlation between body mass or hand size and maximal setting was evident. Those with a maximal grip at setting III or IV did not have larger hands or other features that differed from those with maximal settings at II. If measured at setting II only, maximal grip strength would have been underestimated in about 10% of individuals, but the error was small, ranging from 2% to 24%. Since no feature was identified that predicted maximal grip strength setting, it is recommended that grip strength of all patients should be routinely measured at setting II, irrespective of age, weight, or hand dimensions.
本研究的目的是确定临床测力计的哪种设置能产生最大握力，并将该设置与个体特征相关联。使用计算机化等长测力计，在4至78岁个体的288只正常无症状手中，于测力计的五种尺寸设置下测定最大握力。大多数手（256只，即89%）在设置II时达到最大握力。在设置I或低于设置I时达到最大力量的组，其平均体重和平均身高低于在设置II及以上达到最大力量的个体。然而，体重或手大小与最大设置之间没有明显的显著相关性。在设置III或IV时达到最大握力的人，其手并不比在设置II时达到最大握力的人更大，也没有其他不同特征。如果仅在设置II下测量，约10%的个体的最大握力会被低估，但误差较小，范围为2%至24%。由于未发现可预测最大握力设置的特征，建议无论年龄、体重或手尺寸如何，所有患者的握力都应在设置II下常规测量。
