앞목갈비근 스트레칭이 머리척추각과 가로막 움직임에 미치는 영향 = Effects of Anterior Scalene Muscle Stretching on Craniovertebral Angle and Diaphragmatic Mobility

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to investigate the effects of a four-week anterior scalene muscle stretching exercise on thecraniovertebral angle (CVA) and diaphragmatic mobility in healthy adults.
Methods: Thirty-eight healthy adults (33 males and 5 females) participated in the study and were randomly assigned to eitherthe stretching group or the control group. The stretching group performed anterior scalene stretching exercises three times perweek for 4 weeks, completing 3 sets of 10 repetitions per side per session. The CVA was measured before and after the interventionusing a smartphone application, and diaphragmatic mobility was assessed with an ultrasound device during both quiet and deepbreathing.
Results: The stretching group showed statistically significant improvements in CVA and diaphragmatic mobility during bothquiet and deep breathing (p < 0.05). In contrast, the control group exhibited no significant changes in any of the variables (p >0.05). Between-group comparisons revealed significant differences in CVA and diaphragmatic mobility under both breathingconditions (p < 0.05).
Conclusion: Stretching the anterior scalene muscle positively affected both the craniovertebral angle and diaphragmaticmobility. These findings suggest that incorporating anterior scalene stretching into exercise programs may be beneficialfor individuals with postural misalignment or reduced respiratory function.
