Cumulative Trauma Disorders

Abstract

Data from individual studies and worksites indicate that CTDs are a major problem in some industries. Evidence exists for an association between symptoms of CTDs and occupational risk factors such as forceful exertion, repetitiveness, and extreme postures. Although the pathogenesis of these disorders is not known, they are believed to involve physiological and mechanical responses of soft tissues to repeated or sustained biomechanical stress.The efficacy of ergonomic interventions or programs must be evaluated using the same methods as used to identify problems initially. User (worker) feedback about any job or tool redesigns is essential.Implementing ergonomic interventions likely will be an ongoing, iterative process. The ability of the occupational health nurse to carry out basic nursing functions of health promotion and prevention of injury and illness will be enhanced through the application of the ergonomic principles.
