We studied normal hand strength and the difference between dominant and nondominant hands. Two hundred fourteen volunteers were tested with a calibrated Jamar dynamometer at all five levels. A pinch gauge was used to assess key and pulp pinch. Height, weight, sex, hand dominance, and hobby demands were predictive of maximum grip. Mean maximum grip for women was 81 lb. and for men was 137 lb. Key pinch averaged 22%, while pulp pinch averaged 16% of maximum grip. Only 129 (60%) patients had maximum strengths at level 2. The majority of right-handed subjects were 10% stronger in grip strength on the dominant side. In left-handed subjects, mean grip was the same for both hands; the nondominant hand was stronger in 50% of left-handed subjects.
我们研究了正常手部力量以及优势手与非优势手之间的差异。214名志愿者使用校准后的贾马尔握力计在所有五个级别进行了测试。使用捏力计评估指尖捏力和指腹捏力。身高、体重、性别、手的优势以及爱好需求是最大握力的预测因素。女性的平均最大握力为81磅，男性为137磅。指尖捏力平均为最大握力的22%，而指腹捏力平均为最大握力的16%。只有129名（60%）患者在2级达到最大力量。大多数右利手受试者优势侧的握力强10%。在左利手受试者中，双手的平均握力相同；50%的左利手受试者非优势手更强。
