The effect of Electromyographic activity on the neck and shoulder muscles while reading a book -Position of Prone on forearm and Sitting-

초록

The purpose of this study was to investigate the difference of muscle activity of splenius capitis and upper trapezius on sitting & standing posture. We examed 20 students undergraduate in G college who had healthy man and women. Sitting group of ten subjects read book in sitting posture. Standing group of ten subjects read book in standing posture. We examed splenius captis & upper trapezius muscle activation using electromyography. We selected 0, 60, 180, 300, 600, 900, 1200, 1500, 1800 second time. The results were as follows; There was no significant difference both splenius captis muscle activation during sitting & standing posture(p>.05). There was no significant difference left upper trapezius muscle activation during sitting & standing posture(p>.05). But Rt. upper trapezius muscle activation was significantly increase on prone position more than sitting position between 600 second and 900 second(p<.05). Upper treapzius muscle was more activated on prone position more than sitting position.
