The primary purpose of this study was to establish clinical norms for adults aged 20 to 75+ years on four tests of hand strength. A dynamometer was used to measure grip strength and a pinch gauge to measure tip, key, and palmar pinch. A sample of 310 male and 328 female adults, ages 20 to 94, from the seven-county Milwaukee area were tested using standardized positioning and instructions. Right hand and left hand data were stratified into 12 age groups for both sexes. This stratification provides a means of comparing the score of individual patients to that of normal subjects of the same age and sex. The highest grip strength scores occurred in the 25 to 39 age groups. For tip, key, and palmar pinch the average scores were relatively stable from 20 to 59 years, with a gradual decline from 60 to 79 years. A high correlation was seen between grip strength and age, but a low to moderate correlation between pinch strength and age. The newer pinch gauge used in this study appears to read higher than that used in a previous normative study. Comparison of the average hand strength of right-handed and left-handed subjects showed only minimal differences.
本研究的主要目的是建立20至75岁以上成年人四项手部力量测试的临床规范。使用握力计测量握力，用捏力计测量指尖捏力、钥匙捏力和掌部捏力。对来自密尔沃基地区七个县的310名成年男性和328名成年女性（年龄在20至94岁之间）进行了测试，测试采用标准化的姿势和指导语。将右手和左手的数据按性别分层为12个年龄组。这种分层提供了一种将个体患者的分数与同年龄、同性别的正常受试者的分数进行比较的方法。握力得分最高的是25至39岁年龄组。对于指尖捏力、钥匙捏力和掌部捏力，平均得分在20至59岁时相对稳定，在60至79岁时逐渐下降。握力与年龄之间存在高度相关性，但捏力与年龄之间存在低至中度相关性。本研究中使用的新型捏力计的读数似乎高于先前规范研究中使用的捏力计。对右利手和左利手受试者的平均手部力量进行比较，结果显示差异极小。
