The purpose of this study was to investigate the range of motion and muscle activity in the neck when the work hours or two hours if there is any difference. In this study to achieve the purpose of the study it was chosen as 10 VDT workers. This study was used as a control object and a high-speed camera to analyze a 3D motion analysis program uses Kwon3D XP. And TeleMyo 2400T G2 was used for the analysis of muscle activity of sternocleidomastoid, cervical paraspinals, and upper trapezius. Statistical analysis was carried out for repeated measures ANOVA for comparative analysis of the the Pre, an hour and two hours work, post verification was contrast verification. and statistical analysis using the SPSS 21.0 program.
First, the range of movement of the neck of the VDT working hours showed a significant difference flexion, extension, rotation left and right. And shown to the neck two hours is more rigid than an hour. Also been shown to a high rate of decrease of the rotational range of motion than the flexion and extension. Second, sternocleidomastoid and upper trapezius muscle activity in accordance with VDT working time showed significant differences in both the left and right. And muscle activity of the cervical paraspinals showed a significant difference in left. an hour working time than two hours working time is shown to reduce the muscle activity of the sternocleidomastoid, upper trapezius, and cervical paraspinals. And decrease rate of muscle activity is on the left upper trapezius and cervical paraspinals higher than elsewhere.
Neck rigid was greater than B is to A, the rotation was smaller than the range of motion flexion and extension. sternocleidomastoid, upper trapezius, and cervical paraspinals muscle activity was found to be too low.
