Muscle Strength in Relation to Type of Work and Musculoskeletal Symptoms

Maximal muscle strength during shoulder elevation, arm abduction and handgrip was compared for workers performing repetitive work and more varied work. No difference was found except for shoulder elevation strength of male workers. Furthermore, preliminary analyses on workers performing repetitive work for at least 8 years indicated that the muscle strength of male workers with musculoskeletal symptoms, but not of females, was considerably lower than for asymptomatic workers.
