Working in cold conditions indoors effects on musculoskeletal symptoms and upper limb movements

Abstract: This thesis evaluated the general and local effect of cooling on upper arm movements and muscle function in its relation with musculoskeletal symptoms and complains in working populations. Two experiments were performed in laboratory conditions testing women such a subject. Epidemiology approach was used for evaluate the cold effect on musculoskeletal system in working populations exposed to cold. The results showed that general cooling affected upper arm trajectories due to changes in muscle function parameters. Local leg cooling did not affect upper arm muscle function or trajectories but ability to maintain dynamic balance was reduced.
