Abstract

Purpose. The purpose of this study was to muscle properties analysis of SCM(sternocleidomastoid) Muscle according to posture type when using smartphone. Methods. This study was conducted on 73 college students who are using smartphone. Subjects were analyzed myotonPRO to confirm, prone posture group, stand posture group, drop head above $45^{\circ}$in sit posture on a chair group and drop head below $45^{\circ}$in sit posture on a chair group were measured SCM muscle. The myotonPRO were measured one measurer, total 3 times. Comparative analysis of the each groups were investigated of SCM muscle properties. Results. We found that Frequency, Stiffness, Creep and Relaxation were appeared difference in each posture. F index was increased at drop head below $45^{\circ}$group than stand posture group. S index was increased at drop head above $45^{\circ}$group than prone posture group. C index was decreased at drop head below $45^{\circ}$group and drop head above $45^{\circ}$group than prone posture group. R index was decreased at drop head above $45^{\circ}$group than prone posture group. Conclusions. The muscle properties were appeared difference in each posture of SCM muscle using smartphone.
