This study reports the intrarater and interrater reliability of measurements for elbow flexion (biceps) and shoulder abduction (deltoid) in 27 normal subjects. Testing was done by two physical therapy examiners. For each muscle group tested, the first series of three tests were administered according to the general guidelines described in the dynamometer administration manual and then repeated with increased stabilization procedures (i.e., examiner elbow stabilized against the anterior superior spine). Intrarater and interrater reliability were highest when tested with the examiner elbow stabilized. Intrarater reliability coefficients were in an acceptable range both with and without additional stabilization (0.833 to 0.957) but interrater reliability coefficients were more variable, ranging from a low of 0.518 to a high of 0.840. Mean muscle strength measurements were significantly different between the two examiners. More studies are needed to improve interrater reliability when estimating muscle strength with the hand held dynamometer.J Orthop Sports Phys Ther 1988;9(12):395-398.
本研究报告了 27 名正常受试者肱二头肌（屈肘）和三角肌（肩外展）测量的组内和组间可靠性。测试由两名物理治疗检查者进行。对于所测试的每个肌肉群，首先按照测力计操作手册中描述的一般指南进行三组测试，然后再进行增加稳定性程序的重复测试（即，检查者肘部稳定在前上棘）。当检查者肘部稳定时，组内和组间可靠性最高。在有和没有额外稳定性的情况下，组内可靠性系数都在可接受范围内（0.833 至 0.957），但组间可靠性系数变化更大，范围从低的 0.518 到高的 0.840。两名检查者之间的肌肉力量测量值存在显著差异。需要进一步研究以提高使用手持式测力计评估肌肉力量时的组间可靠性。J Orthop Sports Phys Ther 1988;9(12):395-398.
