Twenty-nine college women participated in a study to investigate the effect of elbow position on grip and key pinch strength evaluations. Standardized instructions and positioning were followed with the exception of the two elbow positions. The elbow was flexed to 90 degrees in one test condition and it was fully extended in the other. The results showed a significantly stronger grip strength measurement in the 90 degree elbow flexed position than in the fully extended position. For evaluation of key pinch strength, both hands were stronger in the elbow flexed position, but only the right hand was significantly stronger. This study supports the use of the elbow flexed position in standardized grip and key pinch evaluations.
29名大学女生参与了一项研究，以调查肘部位置对握力和捏力评估的影响。除了两个肘部位置外，均遵循标准化的指导和姿势。在一种测试条件下，肘部弯曲至90度，在另一种测试条件下，肘部完全伸展。结果显示，在肘部弯曲90度的位置，握力测量值明显强于完全伸展的位置。对于捏力评估，在肘部弯曲位置时双手的力量都更强，但只有右手明显更强。本研究支持在标准化握力和捏力评估中使用肘部弯曲位置。
