The purpose of this investigation was to determine the intratester reliability of measurements obtained with the Nicholas Manual Muscle Tester (NMMT) by a tester having minimal experience on individuals with intellectual disabilities. Seventeen individuals classified as moderately mentally retarded between the ages of 14 and 24 (mean = 18.65) were evaluated with the NMMT using a test-retest reliability procedure after a familiarization session. Test-retest strength score relationships for dominant and nondominant elbow flexors and extensors revealed intraclass correlation coefficients from .83 to .86 (p < .001); whereas a series of paired t-tests revealed no significant differences between test and retest values. Finally, intraclass correlation coefficients ranging from .98 to .99 were evident in comparing the first trial to mean of three trials from the first testing session. It was concluded that testers with minimal experience with the NMMT could obtain reliable measurements with the NMMT for determining isometric force of elbow flexors and extensors in individuals with intellectual disabilities.
本研究的目的是确定经验有限的测试者使用尼古拉斯徒手肌力测试仪（NMMT）对智障人士进行测量时，该测试仪在测试者内部的可靠性。17名年龄在14至24岁之间（平均 = 18.65）、被归类为中度智力障碍的个体，在经过一次熟悉训练后，采用重测信度程序用NMMT进行评估。对优势和非优势肘屈肌及伸肌的重测力量得分关系显示，组内相关系数在0.83至0.86之间（p < 0.001）；而一系列配对t检验显示，测试值与重测值之间无显著差异。最后，在将第一次试验与第一次测试 session 的三次试验平均值进行比较时，组内相关系数在0.98至0.99之间。得出的结论是，对NMMT经验有限的测试者可以使用NMMT获得可靠的测量结果，以确定智障人士肘屈肌和伸肌的等长力量。
