Postural muscle strain as a causal factor in the development of musculo-skeletal illnesses.
Musculo-skeletal complaints account for 30% of time loss through sick leave. A study was made at a small manufacturing plant in Norway among workers subjected to static muscle load, with particular reference to the relationship between such illness and muscle strain due to working conditions. The paper covers old working standards and ergonomic improvements made in 1975. The results show an increase in musculo-skeletal illness with increased length of employment and increased age.
