The relationships between shoulder's function and damage for handball players

Abstract

[Objective] The purpose of this study is to examine the relationships between shoulder's function and damage for handball players. Subjects were nine female handball players with dominant shoulder pain. [Methods] Clinical diagnosis was done from the medical doctor's opinion and MRI. Then, the shoulder joint movement was measured with X rays. [Results] Most of them had admitted a lot the impingement syndrome and the subacromial bursitis. The trunk rotation angle at zero-positions was significantly larger in the symptomatic shoulder (dominant shoulder) than in the asymptomatic shoulder (nondominant shoulder). That is, it was obvious that the damage of the shoulder changed tilting angle of scapula medially. [Conclusion] It is reported that the damage of the shoulder causes abnormality to the "scapulohumeral rhythm" by the previous research. But, these results, suggested to need to understand not only "scapulohumeral rhythm" but also movement to the position of the scapula, when the shoulder joint function was observed for the handball player mainly composed of throwing motion.
