Abstract: ObjectiveTo evaluate the reliability of the Cybex 6000 isokinetic dynamometer in measuring the shoulder extensor contracted concentrically and eccentrically.Methods15 male subjects with no previous shoulder injuries were studied. The extensor muscles groups of asymmetrical shoulder were tested at 60°/s, 120°/s, and 180°/s respectively. Variables studied included peak torque (PT), average power (AP) and total work (TW). The interclass correlation coefficient (ICC) was used to determine the reliability.ResultsHigh test-retest reliability, ICC ranging from 0.86 to 0.97, was demonstrated for all tests.ConclusionThe Cybex 6000 isokinetic dynamometer shows a good reliability in measuring the shoulder extensor isokinetic contracted concentrically and eccentrically.
