N2 - Observation methods have been widely used to assess mechanical exposure in ergonomic epidemiology. In this review study, eight published and still applied observation methods are reviewed and classified with special emphasis on criteria used for classification of body angles and movement intervals. An obvious lack of standardised body angles hampers comparison between methods. A more general question is raised concerning the internal and external validity of observation methods in epidemiologic studies. The internal validity has shown to be acceptable in certain work situations. The external validity of observation methods seems more questionable. Only frequency and duration of movements and posture are included in the methods while other possibly more important risk factors of cumulative trauma disorders, i.e. force, angular velocity, and acceleration are not included. It is suggested that observation methods should be standardised. Furthermore, they should be expanded to include some of the other known risk factors, or alternatively be supplemented by more direct measurements at the workplace.
