摘要: [Purpose] The purpose of this study was to identify changes in the activity and fatigue splenius capitis upper trapezius muscles, which are agonists muscles supporting head, under three postures most frequently adopted while using a smartphone. [Subjects Methods] subjects were 15 college students their 20s. They formed single group had adopt different (maximum bending, middle neutral). While maintained postures, muscle measured surface electromyography. [Results] Comparison caused by each posture showed statistically significant differences for right capitis, left muscles. In addition, maintaining maximum bending smartphone resulted higher levels compared with those posture. [Conclusion] Therefore, suggests that individuals should bend neck slightly when smartphone, rather than it too much, or keep straight reduce cervical erector
