The purpose of this study was to evaluate the reliability of Isomed 2000 dynamometer.We compared the dynamometer and different weight of barbells on torque.Nineteen normal subjects（15male,4female）ages 24.1±5.6with no history of related injury were tested unilaterally for concentric extension/flexion,back at 60°/s,hip at 60°/s,180°/s and 240°/s,knee at 60°/s and 240°/s,ankle at 60°/s,180°/s and 240°/s,shoulder at 60°/s and 180°/s,elbow at 60°/s,180°/s and 240°/s,wrist at 60°/s and 240°/s,utilizing standard Isomed2000 protocol.Each subject was tested two times with an interval of 4-7days.Statistical analysis of data showed that 1）The correlation coefficient（r）between the torque measured and calculated was〉0.999.2）the isokinetic concentric extension/flexion mode for back at 60°/s,hip at 60°/s and 180°/s,knee at 60°/s and 240°/s,ankle at 60°/s and 180°/s,shoulder at60°/s and 180°/s,elbow at 60°/s and 180°/s,wrist at 60°/s and 240°/s of the Isomed 2000 dynamometer was with test-retest reliability ranging from 0.71 to 0.98.3）The intraclass correlation coefficient（ICC）of elbow extension/flexion peak torque and average peak torque at240°/s to be from 0.67 to 0.82,ICC of hip flexion every parameters at 240°/s to be from0.64 to 0.83,ICC of ankle extension（dorsiflexion）every parameters at 240°/s to be from0.36 to 0.82.Conclusions：1）The measurement error of the dynamometer is small and the accuracy is fine.2）The isokinetic concentric extension/flexion mode for hip,elbow and ankle at240°/s of the dynamometer was less or not reliable for test-retest measures of peak torque,work and power;3）Other measures implied good to excellent reliable.
