To measure collective muscle strength, which is directly linked to the performance of work, and to examine the reliability of the measurement, we measured torque generated towards 4 different attachments using BTE Work Simulator R. The subjects of this study were 49 normal young male and female volunteers, who were all dextrals. For all of the 4 attachments, the right side of the upper extremities, the dominant side, showed equal or higher torque values, compared with the left side of the upper extremities. There was a strong correlation between the right and left sides, so the torque value of one side can be used to extrapolate that of the other. As for the reliability of the measurement, ICC presented high values of 0.7 and more, which were high enough for clinical use.
