摘要
背景:握力已被确定为健康状况的重要指标和临床结果的预测因子。测量握力的黄金标准是JAMAR®液压手测力仪。有较便宜的测功机可用，但尚未在医院环境中进行验证。目的:在医院人群中验证凯美瑞数字手柄测功仪(EH101型)与已验证的JAMAR®测功仪(J00105型)。方法:一项横断面观察研究，随机单盲交叉成分，对同意住院的普通医院病房成年患者进行。用惯用手进行的三次测量中最好的一次被用于分析。结果:51名参与者(中位数[四分位数间距]42岁[30-58岁];N = 27例[52.9%]，女性)。贾马尔®和凯美瑞测量值的平均差异为1.9 kg±3.6 kg (t值0.9;P = 0.4)。Jamar®与凯美瑞设备之间存在很强的正相关(R = 0.94;R²= 0.88;P < 0.0001)。Jamar®和Camry测量结果非常吻合(类间相关系数0.97,95% CI 0.94-0.99, p < 0.0001)。手优势显著影响设备之间的一致性(p = 0.002)。结论:凯美瑞数字握力计是评估住院成人患者握力的有效工具。临床意义:凯美瑞数字握力计可以作为一种廉价的工具来测量握力。
Measurement of hand grip strength: A cross-sectional study of two dynamometry devices.
Background: Grip strength has been identified as an important indicator of health status and predictor of clinical outcomes. The gold standard for measuring grip strength is the JAMAR® Hydraulic Hand Dynamometer. Less expensive dynamometers are available but have not been validated within a hospital setting.
Objectives: To validate the Camry Digital Handgrip Dynamometer (Model EH101) against the validated JAMAR® Dynamometer (Model J00105) in a hospital population.
Methods: A cross-sectional observational study with a randomised single-blind cross-over component was conducted on consenting adult patients admitted to general hospital wards. The best of three measurements taken using the dominant hand was used for analysis.
Results: Fifty-one participants (median [interquartile range] age 42 [30-58] years; n = 27 [52.9%] female) were included. The mean difference between the Jamar® and Camry measurements was 1.9 kg ± 3.6 kg (t-value 0.9; p = 0.4). There was a strong positive correlation between the Jamar® and the Camry devices (R = 0.94; r² = 0.88; p < 0.0001). Excellent agreement was found between Jamar® and Camry measurements (interclass correlational coefficient 0.97, 95% CI 0.94-0.99, p < 0.0001). Hand dominance significantly affected the agreement between devices (p = 0.002).
Conclusions: The Camry Digital Handgrip Dynamometer is a valid tool for assessing grip strength in hospitalised adult patients.
Clinical implications: The Camry Digital Handgrip Dynamometer could be used as an inexpensive tool to measure grip strength.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
