Title A randomised controlled trial evaluating an alternative mouse and forearm support on upper body discomfort and musculoskeletal disorders among engineers
Bibliographic information May 2008, Vol.65, No.5, p.311-318. Illus. 31 ref.
Abstract The aim of this study was to determine the effects of an alternative mouse and/or a forearm support board on the change in upper body discomfort scores and the development of incident musculoskeletal disorders. A total of 206 engineers form an engineering firm were followed for one year. Participants were randomised to receive: a conventional mouse only; an alternative mouse only; a forearm support board; an alternative mouse plus forearm support board. Outcome measures included weekly upper body discomfort scores and incident musculoskeletal disorders. During the study, 42 participants were diagnosed with an incident musculoskeletal disorder. The group that received the forearm support board experienced a reduction in their right upper extremity discomfort in comparison to those who did not receive a forearm board. The group that received the alternative mouse had a protective, but non-significant, effect on incident cases of right upper extremity musculoskeletal disorders and a non-significant reduction in neck/shoulder discomfort in comparison to those who received a conventional mouse.
