The Jamar dynamometer has been widely used in various chronic illnesses and has demonstrated its strength as a potential prognostic indicator. Various stratified normative values have been published using different methodologies, leading to conflicting results. No study used statistical techniques considering the non-Gaussian distribution of the obtained grip strength (GS) values. Jamar GS was assessed in 720 healthy participants, subdivided into seven age decade groups consisting of at least 50 men and 50 women each. Normative values (median and fifth values) were calculated using quantile regressions with restricted cubic spline functions on age. Possible confounding personal factors (hand dominance, length, weight, hobby, and job categorization) were examined. Clinically applicable revised normative values for the Jamar dynamometer, stratified for age and gender, are presented. Hand dominance had no influence. Other personal factors only minimally influenced final values. This study provides revised normative GS values for the Jamar dynamometer.
Jamar 握力计在各种慢性疾病中得到了广泛应用，并且已经证明其作为一种潜在的预后指标的实力。已经使用不同的方法学发布了各种分层的规范值，导致结果相互矛盾。没有研究使用考虑到获得的握力 (GS) 值的非正态分布的统计技术。在 720 名健康参与者中评估了 Jamar GS，将他们分为七个年龄十年组，每个年龄组至少有 50 名男性和 50 名女性。使用分位数回归和限制三次样条函数计算年龄的规范值（中位数和第五个值）。检查了可能的混杂个人因素（手优势、长度、体重、爱好和工作分类）。本文提出了针对年龄和性别的 Jamar 握力计的经临床应用修正的规范值。手优势没有影响。其他个人因素仅对最终值产生微小影响。本研究提供了 Jamar 握力计的修正规范 GS 值。
