Physical work exposure and sex differences in work-related musculoskeletal disorders

Thomas Heilskov-Hansen

Abstract

The purpose of the PhD project was to investigate possible gender differences in muscle loading, applied strength, subjectively assessed effort, task distribution and movements in the arms of persons who had the same type of work and to investigate whether a dose-response relationship existed between wrist movements. and Carpal tunnel syndrome (CTS) and whether men and women with the same type of work had a different risk for CTS.

We examined Danish building painters, as painters have a high proportion of women and supposedly a homogeneous distribution of tasks. For the data collection, electromyography, Borg CR10 scale, questionnaire, information on diseases and operations from Danish registers, gonio- and inclinometry were used. The relative muscular load was significantly higher in women than in men, and this correlated with subjective assessments of physical exertion. Minimal gender differences in applied strength were found, with highest values ​​in men. Only minor gender differences were found in the task distribution, and no significant differences between the sexes were found for posture and movement of the upper musculoskeletal system. A dose-response relationship was found between the mean speed of the wrist and CTS, and a measure of repetition and CTS. There was no significant effect of the cumulative load between 1 and 5 years prior to a CTS case. The risk of CTS was significantly higher in women than in men with comparable exposures, but the effect of exposure was not modified by gender.
