Health Hazard Evaluation Report HETA 89-299-2230, US West Communications,Phoenix, Arizona; Minneapolis, Minnesota; Denver, Colorado

摘要

In response to a request from US West Communications (SIC-4813) and theCommunications Workers of America, an evaluation was undertaken of the effects of the use of video display terminals on the musculoskeletal systems of Directory Assistance Operators. Information on the type of workstations, job requirements, and worker health was gathered. Two types of musculoskeletal outcomes were identified for analysis: potential work related upper extremity musculoskeletal disorders defined by physical examination and questionnaire, and upper extremity musculoskeletal symptoms defined by questionnaire alone based on a cumulative score of symptom duration, frequency and intensity. The authors conclude that there was a high prevalence of potential work related musculoskeletal disorders and symptoms. Factors associated with these disorders include demographics, prior medical conditions, work practices, psychosocial aspects of the workplace, and electronic performance monitoring. Most of the physical workstations observed were of high ergonomic quality. The psychosocial work environment may be related to the occurrence of work related upper extremity musculoskeletal symptoms and disorders. The authors recommend specific measures to improve working conditions and possibly prevent and control musculoskeletal disorders.
