Effect of Self-and Manual-Myofascial Release on the Pectoralis Minor Index and the Muscle Tone in Individuals with Round Shoulder

The purpose of this study was to compare effects of self-myofascial release using a foam roller and the manual-myofascial release on the pectoralis minor index and the muscle tone in individuals with round shoulders. Thirty two participants who had round shoulder were involved in this study. The participants measured the pectoralis minor index and muscle tone before and after the myofascial release. For the myofascial release of this experiment, self-myofasical release using foam roller and manual-myofasical release were applied. The same the myofascial release was applied to all participants, and the order of the myofascial release was randomly assigned. There was a significant difference in the pectoralis minor index before myofascial release, after self-myofascial release, and after manual-myofascial release. However, there was no statistically significant difference in the pectoralis minor index between self-myofascial release and manual-myofascial release in the post hoc test. The self-myofascial release and manual-myofascial release effectively improve pectoralis minor index. Therefore, the self-myofascial release is an alternative intervention to manual-myofascial release for improving pectoralis minor index in individuals with round shoulder.
