Occupational Cervicobrachial Disorder in Assembly Plant

A fact-finding survey on Occupational Cervicobrachial Disorder in an assembly plant is described. In this plant, amplifiers of stereophonic sound system were assembled on the conveyor lines. About 90 workwomen were engaged in the lines and majority of them repeatedly used the arms and hands with the posture being restrained to the lines. 25 workwomen aged 18 - 30 who complained of stiffness and pain over the shoulder and neck etc. were examined. And working conditions were analysed from the viewpoint of industrial health. Occupational Cervicobrachial Disorder had been considered to be peculiar to business machine operators. But as a result of this survey, it was made clear that Occupational Cervicobrachial Disorder was not peculiar to business machine operators and might develop in assembly plant workers in bad working conditions.
