Self-reported physical exposure and musculoskeletal symptoms of the forearm-hand among automobile assembly-line workers.

Abstract

The aim was to study the prevalence of physical exposures and symptoms of the forearm-hand in a population with highly repetitive jobs. Automobile assembly-line workers (ALWs) (n = 521) and a control group (CG) from the general population answered a questionnaire. Consistent differences were found between the groups. ALWs reported more symptoms from the forearm-hand and higher exposure to repetitive movements, precision movements, and manual handling (< or = 15 kg) than the CG. Female ALWs reported more symptoms and higher exposure to known risk factors for work-related forearm-hand disorders than their male colleagues. In conclusion, automobile assembly-line workers appear to be a high-risk group for work-related symptoms from the forearm-hand. Also, exposure to physical load should be conscientiously analyzed, since women may perform different tasks than men.
