초록

The purpose of this study is to investigate the effects of neck·scapula corrective exercise on static posture balance and muscle stiffness. Sixty-one university students (22±4.39 year) participated in this study. Corrective exercise included myofascial release and isometric exercies was applied on neck, shoulder and scapula r region for 17 min. To evaluate the static posture, forward head angle·length, Scapula flexion angle were measured using a posture analysis device(exbody 550 series, seoul, Korea) at rest and right after corrective exercise. In order to measure the mechanical properties like muscle stiffness and elasticity, MyotonPro(Myoton AS, Tallinn, Estonia) was applied to muscle belly of trapezius·sternocleidomastoid muscle at rest and right after corrective exercise. From the Myoton measurement, Five indexes (Frequency, Logarithmic Decrement, Dynamic Stiffness, Creep, Mechanical Stress Relaxation) were obtained. The results were as follows .
Firstly, Forward head angle and length decreased significantly after corrective exercise compared to pretreatment( p<.05~.001). Secondly, Scapula flexion angle during overhead squa t posture increased significantly after corrective exercise compared to pre-treatment(p<.05). Thirdly, in the mechanical muscle properties , tension of upper trapezius·stermocleidomastoid muscle increased significantly while the elasticity of upper trapezius muscle deceased significantly after corrective exercise(p<.05~.001). These results suggest that corrective exercise applied on neck and shoulder region might be effective in improving static posture balance and mechanical muscle properties.
