Abstract

Purpose
This study investigated effect of the scapular retraction exercise on the subacromial and costoclavicular space using different thera-band intensities.
Methods
Thirty-six healthy adults participated in this study, and the subjects were randomly divided into three groups (low, moderate, and high-intensity groups). The exercise was conducted twice a week for three weeks. The subacromial and costoclavicular space were measured before and after the intervention via ultrasonography. Data analysis was performed using the two-way Analysis of Variance with repeated measures and the paired t-test.
Results
The effect of the scapular retraction exercise on the subacromial and costoclavicular space using a thera-band after a 60° shoulder abduction has significant difference in all groups (p< 0.05). However, there was no significant difference between the groups, and the values in the groups before the exercise did not differ significantly from those after the exercise (p> 0.05).
Conclusion
Our results indicate that the scapular retraction exercise after a 60° shoulder abduction can be used to widen the subacromial and costoclavicular spaces.
