근전도분석에 의한 VDT작업의 누적외상에 관한 연구 = A Study on CTDs of VDT works by EMG analysis

다국어 초록 (Multilingual Abstract)

Due to the repeatative motion for the long periods, the cumulative trauma disoders(CTDs). Causing damage in muscle, joint, brood vessel, and nerves etc, bring up the social and economical problems invalving safety in industry and public health. CTDs are oftenly observed in blue color workers who have jobs requiring the simple repeatative motion such as computer operators and workers in assembly line. In this study EMG system was used to the measure the muscle forces and to the experimental data for evaluating fatigue in CDTs. The results of measuring averaged interated EMG(AEMG) signals show that the flexor carpi ularis muscle in the left arm is used more than other muscles. Commonly, muscle fatigue of flexor carpi ularis and extensors of the wrist is higer than muscle fatigue of analyze trapezius muscle.
