Objective: The purpose of this study was to investigate the effects of sling exercise on the cervical lordotic angle, craniovertebral angle, and head rotation angle among adolescents in the forward head posture.
Methods: The subjects include 22 adolescents that recorded a mild level or higher on the posture evaluation index by New York State. They were randomly divided to the hand exercise group (n=11) and the control group (n=11). The former group participated in the sling exercise program three times a week over four weeks in total with each session lasting 60 minutes, whereas the latter group was not included in the program. The cervical lordotic angle, craniovertebral angle, and head rotation angle were measured before and after the intervention.
Results: The study compared the cervical lordotic angle between the two groups before and after sling exercise and found that the sling exercise group made an increase 7.36’of from 21.91’to 29.27’after the intervention(p<.05). As for the comparison results of the craniovertebral angle, the sling exercise group made an increase of 5.64’ from 48.91’to 54.55’ after the intervention (p<.05). As for the comparison results of the cranial-rotation angle, the sling exercise group made an decrease of -7.73’from 148.82’to 141.09’after the intervention (p<.05). The control group showed no differences before and after the intervention (p>.05).
Conclusion: Those findings indicate that the application of sling exercise in the forward head posture can be a good program to maintain the right posture and improve or prevent an abnormal posture and raise a need for more clinical applications and ongoing researches.
