The purpose of this study was to evaluate the reliability of Tekdyne hand dynamometer in a controlled loading environment using the Instron 1331. Test-retest reliability, the intertool reliability of three different Tekdyne hand dynamometers, and the effects of surface area and the configuration of the forces applied to the Tekdyne hand dynamometer were studied. In addition, intertool reliability between a Jamar dynamometer modified with foam padding and the same Jamar dynamometer without padding was calculated to explore this device as an alternative measurement device. Intratool and intertool reliabilities of the three Tekdyne tools were high (ICC = 0.993-10.998, SEM = 0.106-0.045 psi and ICC = 0.995, SEM = 0.080 psi, respectively) when tested on the Instron. Both the surface area and the configuration of the force applied to the Tekdyne dynamometer appeared to influence the output reading of this device. The measurements obtained on the Tekdyne hand dynamometer correlated well with those obtained with the Jamar hand dynamometer when a controlled load was applied (r = 0.988). The Tekdyne hand dynamometer is a reliable tool in a controlled loading environment; however, further study is needed to determine its validity with respect to the Jamar dynamometer for testing human grip strength.
本研究的目的是在使用英斯特朗1331的受控加载环境中评估Tekdyne握力计的可靠性。研究了重测可靠性、三种不同Tekdyne握力计的工具间可靠性，以及作用于Tekdyne握力计的表面积和力的配置的影响。此外，计算了用泡沫衬垫改良的Jamar握力计与未加衬垫的同一Jamar握力计之间的工具间可靠性，以探索该设备作为替代测量设备的可能性。在英斯特朗上进行测试时，三种Tekdyne工具的工具内和工具间可靠性都很高（ICC分别为0.993 - 10.998，SEM为0.106 - 0.045 psi；ICC为0.995，SEM为0.080 psi）。作用于Tekdyne握力计的表面积和力的配置似乎都会影响该设备的输出读数。当施加受控负载时，Tekdyne握力计上获得的测量值与Jamar握力计上获得的测量值相关性良好（r = 0.988）。Tekdyne握力计在受控加载环境中是一种可靠的工具；然而，需要进一步研究以确定其相对于Jamar握力计在测试人类握力方面的有效性。
