IMPORTANCE
Handgrip dynamometry is probably the most commonly used method to characterize overall human muscle strength.
OBJECTIVE
To compare and summarize grip strength measurements obtained from two population-based studies.
DESIGN
Secondary data analysis.
SETTING AND PARTICIPANTS
Data from (1) the 2011-2014 National Health and Nutrition Examination Survey (NHANES) with 13,918 participants and (2) the 2011 normative phase of the National Institutes of Health (NIH) Toolbox project with 3,594 participants.
OUTCOMES AND MEASURES
The NHANES values used were the mean and best of three trials; the NIH Toolbox value used was the one maximum trial after a practice trial.
RESULTS
General linear model analysis revealed that values obtained from the NIH Toolbox differed from NHANES best values but not from NHANES mean values. The analysis also indicated, regardless of the values used, that grip strength differed significantly between dominant and nondominant sides, males and females, and age groups. We provide updated reference values for handgrip strength.
CONCLUSIONS AND RELEVANCE
On the basis of these analyses, we summarize grip strength measures obtained from the NHANES and NIH Toolbox for side, gender, and age group strata. Reference values are essential to assist in the interpretation of testing results and clinical decision making.
重要性
握力测量法可能是表征人体整体肌肉力量最常用的方法。
目的
比较并总结两项基于人群的研究中获得的握力测量结果。
设计
二次数据分析。
设置与参与者
数据来自（1）2011 - 2014年美国国家健康与营养检查调查（NHANES），有13918名参与者；（2）美国国立卫生研究院（NIH）工具包项目2011年的标准化阶段，有3594名参与者。
结果与测量指标
NHANES使用的数值是三次试验的平均值和最佳值；NIH工具包使用的数值是一次练习试验后的一次最大试验值。
结果
一般线性模型分析显示，NIH工具包获得的数值与NHANES的最佳值不同，但与NHANES的平均值没有差异。分析还表明，无论使用何种数值，握力在优势侧和非优势侧、男性和女性以及不同年龄组之间存在显著差异。我们提供了握力的更新参考值。
结论与意义
基于这些分析，我们总结了从NHANES和NIH工具包中获得的不同侧别、性别和年龄组分层的握力测量结果。参考值对于辅助测试结果的解读和临床决策至关重要。
