| Outline of Final Research Achievements |
The purpose of this study was to investigate relationships among defective pitching mechanics, joint kinetics, prognosis from MRI image, and onset of shoulder injury. Among 14 college baseball pitchers and 12 semi-professional pitchers, three pitchers developed shoulder injuries during the survey: Two of them had severe glenoid labrum tear which required over 2 months for recovery.
Common features of the injured pitchers were deficit of range of motion for sternoclavicular joint and timing of abrupt increase of shear force ratio to normal force. It suggests that movement of not only glenohumeral joint but whole shoulder girdle is important to prevent shoulder injury. We could not predict shoulder injury from the joint kinetics and MRI images.
