Sewing-machine operators' work and musculo-skeletal complaints.

The purpose of the study was to obtain information about the possible occupational origin of the high occurrence of musculo-skeletal (rheumatic) complaints among sewing-machine operators. The subjects were chosen by random sampling and comprised 40 sewing-machine operators with short work cycles (30-60 s) and 20 seamstresses as the reference group. The two groups were matched with respect to age and length of service. A survey of working postures showed that the sewing-machine operators' work was more static. Musculo-skeletal complaints occurred more frequently among the sewing-machine operators, especially in the neck and shoulders (p<0.01) and the lower limbs (p<). It is concluded that the occupational change from seamstresses' work to sewing-machine operators' work is associated with an increase in the occurrence of musculo-skeletal complaints.
