Title Factors associated with self-reported musculoskeletal discomfort in video display terminal (VDT) users
Bibliographic information June 2002, Vol.29, No.6, p.311-318. Illus. 34 ref.
Abstract The purpose of this study was to identify risk factors based on self-reported musculoskeletal discomfort in a population of video display terminal operators. 292 responses to a questionnaire were analysed. Questions included symptoms for several body regions, job requirements, demographic information and hobbies. The following body regions were studied: head and eyes, neck and upper back, lower back, shoulders, elbows and forearms, hands and wrists. Results indicated a statistically significant increased risk of discomfort on each of the body regions as the number of hours of keyboard use increased. Improper monitor and keyboard position was also significantly associated with head and eye, and shoulder and back discomfort, respectively. These results emphasize the importance of workstation ergonomics and the need to limit the number of uninterrupted hours at the keyboard to reduce musculoskeletal symptoms.
