[Outbreak of carpal tunnel syndrome of the upper limbs in automobile seat assemblers: results of exposure evaluation and clinical investigation].
A group of 59 female workers in the sewing and upholstery departments of a factory manufacturing automobile seats underwent clinical and instrumental tests following reports of several cases of suspected carpal tunnel syndrome. A risk evaluation analysis for disorders attributable to repeated trauma of the upper limbs (WMSDs) was simultaneously carried out using the protocol recommended by the EPM Research Unit in Milan. Evidence was found of a high frequency of elementary actions associated with considerable muscular involvement along with inadequate recovery periods. The clinical investigation revealed an unusually high percentage of carpal tunnel syndromes, often associated with Guyon channel syndrome. This disorder affects males and females equally, is often bilateral, and is not associated with known non-occupational factors. The widespread outbreak of work-related musculo-skeletal disorders reported in the departments in question may have arisen from a combination of significant risk factors relating to the types of activities performed, and the long service of the workers. It is reasonable to assume that failure to adopt technical preventive and organisational measures may have stemmed primarily from a poor evaluation of the relevant occupational risks, and from many years of substandard health surveillance practices.
