In clinical day-to-day life, grip strength, key pinch, and range of motion (ROM) serve to objectively evaluate treatment outcomes on wrist interventions. The goals of this study were to generate normative values of wrist function including the parameters of grip strength, key pinch, wrist ROM, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores in a healthy, working population, and to investigate the influence of age, sex, body weight and height, handedness, and work strain.
We clinically examined 750 volunteer working subjects (363 women and 387 men, all white). We divided subjects into 2 groups depending on whether their labor involved high or low manual strain. We recorded participants' height, weight, grip strength, pinch strength, and wrist ROM. Each participant filled out a DASH questionnaire.
Grip strength and pinch strength showed a maximum at between 30 and 49 years of age. In men, body mass index, body height, and weight all correlated with grip strength and pinch grip. Whereas women exhibited greater grip strength on the right side, men showed nonsignificant greater grip strength on the left side. Wrist ROM was greatest for ages ranging between 18 and 29 years. The average DASH value for all male subjects was significantly less than that of female subjects. In a healthy working population, the DASH score increased yearly by an average of 0.2 points in men and 0.3 points in women.
This study showed that in a healthy working population, people 30 to 49 years of age had the highest grip strength and pinch strength. Age positively correlated with the DASH score and inversely related to wrist ROM. Persons employed in jobs with high manual strain presented with lower wrist ROM and higher DASH scores.
These data help to objectively evaluate wrist function and the effectiveness of therapeutic interventions.
在临床日常生活中，握力、捏力和活动范围（ROM）有助于客观评估手腕干预的治疗效果。本研究的目的是生成健康工作人群手腕功能的规范值，包括握力、捏力、手腕活动范围和手臂、肩部和手部功能障碍（DASH）评分等参数，并研究年龄、性别、体重和身高、用手习惯以及工作压力的影响。
我们对750名在职志愿者受试者（363名女性和387名男性，均为白人）进行了临床检查。根据劳动强度高低将受试者分为两组。我们记录了参与者的身高、体重、握力、捏力和手腕活动范围。每位参与者填写了一份DASH问卷。
握力和捏力在30至49岁之间达到最大值。在男性中，体重指数、身高和体重均与握力和捏力相关。女性右侧握力更强，而男性左侧握力虽无显著差异但稍强。手腕活动范围在18至29岁之间最大。所有男性受试者的平均DASH值显著低于女性受试者。在健康工作人群中，男性的DASH评分每年平均增加0.2分，女性平均增加0.3分。
本研究表明，在健康工作人群中，30至49岁的人握力和捏力最高。年龄与DASH评分呈正相关，与手腕活动范围呈负相关。从事高强度体力劳动的人手腕活动范围较小，DASH评分较高。
这些数据有助于客观评估手腕功能和治疗干预的效果。
