PURPOSE
To determine reference ranges for peak, average, and final adult grip strength over 10 seconds by using an electronic dynamometer, and to compare results from hydraulic and electronic dynamometers.
METHODS
The hand-grip strengths of 476 healthy adult subjects were tested using the electronic (Grippit; AB Detektor, Goteborg, Sweden) and hydraulic (Jamar; Smith and Nephew, Memphis, TN) dynamometers.
RESULTS
Age- and gender-specific reference ranges for the Jamar and Grippit dynamometers are presented. Bland-Altman analysis of the differences between the results obtained using the 2 instruments revealed a bias (mean difference) of 22 N (Jamar - Grippit) and limits of agreement of -86 to 129 N (mean +/- 2 SD), which indicates that grip measurements may vary by up to 215 N between instruments.
CONCLUSIONS
The study yielded population reference ranges of peak, average, and final strength over a 10-second grip assessment using an electronic dynamometer. Results from the Grippit and Jamar dynamometers are similar; however, the dynamometers cannot be interchanged. The Grippit provides information about endurance and fatigue of grip over 10 seconds, showing differences between right- and left-dominant adults.
目的
使用电子测力计确定成人10秒内握力峰值、平均握力和最终握力的参考范围，并比较液压测力计和电子测力计的测试结果。
方法
使用电子测力计（Grippit；AB Detektor，瑞典哥德堡）和液压测力计（Jamar；Smith and Nephew，美国田纳西州孟菲斯）对476名健康成人受试者的握力进行测试。
结果
给出了Jamar和Grippit测力计按年龄和性别的参考范围。对两种仪器测试结果差异的Bland-Altman分析显示，偏差（平均差异）为22 N（Jamar - Grippit），一致性界限为-86至129 N（均值±2标准差），这表明不同仪器间的握力测量值可能相差高达215 N。
结论
本研究得出了使用电子测力计进行10秒握力评估时峰值、平均和最终力量的人群参考范围。Grippit和Jamar测力计的结果相似；然而，两种测力计不能互换使用。Grippit可提供10秒内握力耐力和疲劳的信息，显示出右利手和左利手成年人之间的差异。
