This study compared the results obtained from testing grip strength using the hydraulic Jamar dynamometer and the BTE Work Simulator. The grip strength of 14 adults was assessed with the Jamar at 90 degrees elbow flexion, Jamar at 45 degrees elbow flexion, and the BTE using the manufacturers recommended position. Greater strength measurements were generated with the elbow at 90 degrees rather than 45 degrees on the Jamar. The Jamar measurements at 90 degrees of elbow flexion were not significantly different from the BTE work simulator values. Intraclass correlation coefficients between the Jamar at 90 degrees and the BTE work simulator values were excellent. This study demonstrated that the results obtained from the BTE work simulator and the Jamar dynamometer are comparable. These findings validate the use of the BTE work simulator for grip strength testing.
本研究比较了使用液压Jamar握力计和BTE工作模拟器测试握力所获得的结果。对14名成年人的握力进行了评估，分别在肘部屈曲90度时使用Jamar握力计、肘部屈曲45度时使用Jamar握力计以及使用BTE工作模拟器并采用制造商推荐的姿势。在Jamar握力计上，肘部处于90度时所测得的力量大于肘部处于45度时的力量。肘部屈曲90度时Jamar握力计的测量结果与BTE工作模拟器的值无显著差异。肘部屈曲90度时Jamar握力计与BTE工作模拟器值之间的组内相关系数极佳。本研究表明，从BTE工作模拟器和Jamar握力计获得的结果具有可比性。这些发现验证了使用BTE工作模拟器进行握力测试的可行性。
