The way the shoulder joint works in the shoulder complex is completely different system when compared with other joints. Therefore, the estimations using an isokinetic dynomometer are not always parallel to the correct shoulder function. We wish to report the check points and the clinical values of these estimation.
(Method)
10 normal volunteers were examined. Each person was measured using a Kin-Corn 500H under various conditions at 60 El / sec and concentric contraction.
(Results)
1) It was difficult to measure the peak torque and peak force correctly, especially for external rotation and internal rotation.
2) Each person was examined for abduction under various conditions. The force scattered in each under various conditions, for example, whether the body was fixed or not, and the supination or pronation of the forearm. It was difficult to measure under same and correct conditions.
(Conclusion)
When we measured the muscle strength of the shoulder joint using an isokinetic dynamometer, the most important point was to establish the measuring position and conditions.
