|
Purpose : The purpose of this study was to find out the effect of diaphragmatic breathing and muscle activities of sternocleidomastoid(SCM) from cranio-cervical flexion exercise(CCFE) and the changes in respiratory functions of young adults with forward head posture.
Methods : The subjects of the study are thirty young adults with forward head posture. They were divided into two groups according to the way they exercise and they participated in the experiment two times a day for a week. A group has carried out CCFE with diaphragmatic breathing, and the other has only implemented CCFE. Spirometer was used to measure pulmonary function, and muscle activities SCM were measured by Surface electromyograph(EMG). Measured value was analyzed by paired T-test.
Results : There were significant differences in muscle activities of SCM between experimental group and control group(p<.05), but there was no big difference in variation(p>.05). There were only statistically evident differences in peak expiratory flow(PEF) and maximal voluntary ventilation(MVV) regarding lung function(p<0.05).
Conclusion : On the basis of these results, the study shows that CCFE could positively affect decreased muscle activities of SCM and the improvement of cardio pulmonary function.
