Profile of the musculoskeletal pain suffered by textile tufting workers handling thread cones according to work, age and employment duration

Abstract

This paper studies the relationship between some socio-professional characteristics of workers (e.g. age, actual work done, experience in the job, overall time on job market, height) carrying out thread-cone handling tasks and their musculoskeletal pain profiles. Interviews were carried out with foremen and workers, and task analysis was performed. Self-administered questionnaires on work-related pain were filled out by 114 machine operators and creelers in four carpet-manufacturing companies. Statistics on nine individual and 25 pain-symptom characteristics were compiled. For data treatment, two statistical methods complemented one another: the Factorial Analysis of Correspondence (FAC) and the Hierarchical Ascendant Classification (HAC). Four classes of workers showing large differences one to another regarding time of employment on the job market, age, seniority in the company, and job experience were portrayed. No remarkable differences were found between the classes in relation to the proportion of workers showing body pain symptoms; it is greater than 50% in all classes (12 months). Moreover, in all classes, for several workers, the first region of pain (out of three possible) was reported as one persisting over the weekend. The group of workers from 25 to 35 years of age appears to be the one most seriously affected by musculoskeletal pain.
