The primary purpose of this study was to develop, implement and evaluate an ergonomics training program aiming at the recognition and control of cumulative trauma disorders of the upper extremity by employees in a manufacturing industry.

A training model was developed and implemented in a controlled study with ten employees in one department of a small manufacturing company. The results obtained showed that the training had a significant effect in decreasing the degree of exposure to risks associated with upper extremity cumulative trauma disorders in the short term, as measured by a biomechanical risk index. The work methods used by workers were recorded on video for analysis of degree of exposure to risks. Pre-instruction and post-instruction tests on knowledge did not show any significant increase between the training and control groups. Reproduced
