[目的]本研究的目的是评估使用腰带约束的手持式测力仪进行等长肌力测量或重测的可靠性。[研究对象]37例健康成人(男18例，女19例)，平均年龄21.9岁。[方法]使用手持式测力仪(东京Anima公司的Mu Tas MF-01或F-1)和皮带固定被测身体部位，对优势腿进行测量。评估了以下10组肌肉的力量：髋部的屈肌、伸肌、外展肌、内收肌、内旋肌和外旋肌；膝关节的屈肌和伸肌；以及踝关节的背屈和足底屈肌。每项测量在休息至少30秒后，分三次进行：上午、当天下午和一周后。[结果]每一次测量的组内相关系数(ICC)为0.75~0.97。在三次训练中，每组肌肉的最高测量系数在0.56到0.91之间。[结论]使用带稳定带的手持式测力仪测量小腿等长肌力的重测信度因所测肌肉动作的不同而有较大差异，最好在不同场合重复测量。
[Purpose] The aim of this study was to evaluate the test-retest reliability or isometric muscle strength measurements made using a hand-held dynamometer restrained by a belt. [Subjects] The Subjects were 37 healthy adults (18 men and 19 women) with a mean age of 21.9 years. [Methods] Measurements were made on the dominant leg using a hand-held dynamometer (mu Tas MF-01 or F-1, Anima Corp., Tokyo) and a belt to fix the position of the body part under test. The strengths of the following 10 muscle groups were evaluated: flexors, extensors, abductors, adductor, internal rotators and external rotators of the hip; flexors and extensors of the knee; and dorsiflexors and plantar flexors of the ankle. Each measurement was repeated after at least 30 seconds of rest in three sessions: in the morning, in the afternoon on the same day, and one week later. [Results] The intraclass correlation coefficient (ICC) for the first and second sets of measurements made in each session ranged from 0.75 to 0.97. ICC for the highest measurements of each muscle group in each of the three sessions ranged from 0.56 to 0.91. [Conclusions] The test-retest reliability of isometric Muscle strength measurements of the lower limb made using a hand-held dynamometer equipped with a stabilizing belt varies widely, depending on the muscle action tested, and it would be better to repeat the measurements on different occasions.
