Two raters performed hand-held dynamometer testing of six muscle groups of 30 patients to determine the interrater reliability of the procedure. The six muscle groups tested were the shoulder external rotators, elbow flexors, wrist extensors, hip flexors, knee extensors, and ankle dorsiflexors. The patients were of eight different diagnostic groups, with most having hemiparesis secondary to cerebrovascular accidents. We used Pearson product-moment correlations and t tests to compare the two raters' score. The correlation coefficients ranged from .84 to .94 (p less than .001). Only two muscle groups (ie, shoulder external rotators and wrist extensors) had mean scores that differed (p less than .05) between raters. Although the interrater reliability of the procedure was found to be good to high in the six muscle groups tested, the results of the t tests indicate that hand-held dynamometry should undergo further evaluation.
两名评估者对30名患者的6个肌肉群进行了手持测力计测试，以确定该测试方法的评估者间信度。所测试的6个肌肉群分别为肩部外旋肌、肘部屈肌、腕部伸肌、髋部屈肌、膝部伸肌和踝部背屈肌。这些患者分属8个不同的诊断组，大多数患有脑血管意外继发的偏瘫。我们使用皮尔逊积差相关系数和t检验来比较两名评估者的评分。相关系数范围为0.84至0.94（p小于0.001）。只有两个肌肉群（即肩部外旋肌和腕部伸肌）在评估者之间的平均得分存在差异（p小于0.05）。尽管在所测试的6个肌肉群中该测试方法的评估者间信度被发现为良好至高度可靠，但t检验结果表明手持测力计测试仍需进一步评估。
