Abstract

|
|
Purpose : The purpose of this study was to compare the effect of exercise on the neck muscles activities between scapular stability and McKenzie stretch exercise in the forward head posture subjects.
Method : After measuring cervical alignment using the Global Posture System, 20 volunteers with forward head posture posture were selected and divided into two groups. The experimental group A(n=15) and Experimental group B(n=15) participated in respectively and McKenzie neck stretching exercise, three times per week for 4 weeks. The scapular stabilization exercise program was comprised middle and lower trapezius strength exercises and the stretching exercise program was comprised levator scapulae and upper trapezius stretching exercise. The activities of the muscles of the posterior neck was then measured using electromyography.
Result : After the intervention, there was significant difference of a electromyography activity changes between the pre-test and post-test in the experimental group.
Conclusion : This study showed that both scapular stabilization and McKenzie neck stretching exercises are more effective for reducing neck muscles activities.
