Abduction strength of the thumb was measured in normal men (n = 101; age range, 21-94 years) and women (n = 208; age range, 20-97 years). Abduction-strength measurements were conducted concurrently with grip and pinch strength measurements made by well-established clinical methods. Normal values were established and stratified by age and sex. Thumb abduction strength generally correlated with grip and pinch strength. All strength variables at all ages were greater in men than in women. The magnitude of all strength variables was maintained from 20 to 59 years of age, then decreased with increasing age in both men and women. Measurement of thumb abduction strength may prove to be a useful adjunct to the various tests currently used by hand surgeons to assess hand function.
对101名正常男性（年龄范围为21 - 94岁）和208名正常女性（年龄范围为20 - 97岁）测量了拇指外展力量。外展力量测量与通过成熟临床方法进行的握力和捏力测量同时进行。确定了正常值，并按年龄和性别进行分层。拇指外展力量一般与握力和捏力相关。各年龄段所有力量变量在男性中均大于女性。所有力量变量的大小在20至59岁时保持稳定，之后在男性和女性中均随年龄增长而下降。拇指外展力量的测量可能被证明是手部外科医生目前用于评估手部功能的各种测试的有用辅助手段。
