Purpose : This study was performed to comparison of distance change of subacromial space according to shoulder abduction angle in loaded and unloaded conditions.
Methods : The subjects were 20 male college students, and the subacromial space was measured using an ultrasound diagnostic apparatus. The participants shoulder abduction was measured during each shoulder resting position and 45 ° abduction with loads of 1 ㎏, 2 ㎏, 3 ㎏. The collected data were analyzed by a paired t-test and repeated measure ANOVA with the SPSS (Ver. 22) program.
Results : The subacromial space showed statistically significant decreased in 45 ° abduction than resting position (p<.001). All the subacromial space increased during the according to loads (1 ㎏, 2 ㎏, 3 ㎏) at the resting position but at 45 ° abduction showed statistically significant decreased as the load increases (p<.05). Also, subacromial space showed significant changes in the 2㎏, 3㎏ compared with the 0㎏ loads.
Conclusion : These results identified that shoulder abduction angle and load were related to subacromial space. When
resting position, subacromial space is larger at loads than unload. As the load and shoulder abduction angle increase, subacromial space is reduced compared to resting.
