Ergonomic risk assessment: preliminary guidelines for analysis of repetition, force and posture.

Abstract

High repetition, excessive forces and awkward postures are a major cause of musculoskeletal disorders in industry. Thus, the main objective of this paper is to develop, based on the published literature, preliminary ergonomic guidelines for repetition, force, and posture task analysis. A method is also proposed which can be used to compute the interactive effects of repetition, force and posture.
