Changes in rounded shoulder posture and forward head posture according to exercise methods

[Purpose] This study aimed to determine the effect of forward head posture-improving exercises on rounded shoulder posture when employing the self-stretch exercise, the McKenzie exercise, and the Kendall exercise as intervention methods based on previous studies that reported negative effects of unbalanced posture and musculoskeletal problems on forward head posture and rounded shoulder posture. [Subjects and Methods] The selected 28 subjects were randomly assigned into the McKenzie exercise group (n=9), the self-stretch exercise group (n=10), and the Kendall exercise group (n=9). To compare the forward head posture, the craniovertebral angle was used. To measure the rounded shoulder posture, the scapular index was used. [Results] There were significant differences in the craniovertebral angle and scapular index within the groups and no significant differences between the groups. [Conclusion] The result of this study showed that all interventions increased the craniovertebral angle and the scapular index, which revealed that the applied exercises had a positive effect on forward head posture and rounded shoulder posture.
