| Outline of Final Research Achievements |
We attempted to capture rotational motion of glenohumeral joint of healthy adults and patients with shoulder disorder using MRI and to determine whether rotator cuff movement could be evaluated using by cine-MRI. Cine-MRI produced scans of the rotator cuff’s coordinated movements with vivid clarity. There was no significant difference between active and passive motions regarding the range of motion in normal shoulder. All cases maintained congruity in normal group, however, 6% of patients' shoulders were confirmed the loss of congruity. Patient group were significantly limitted in internal, external rotation, and total range of rotation. Patients with the external rotational limitation were significantly lower than other patients in constant score. And, rotational range of motion of patients with night pain was significantly smaller than patients without night pain. In our results, the limitation of rotation of glenohumeral joint is thought to be related with shoulder disorder.
