ABSTRACT
Repetitive motion injury (RMI) or cumulative trauma disorder (CTD) has been increasingly recognized in ergonomics during the last 20 years. But going back in history, RMI had already been recognized in 1717 by Ramazzini in Italy. He described RMI among office clerks and believed that these events were caused by repetitive motions of the hand, by constrained body postures, and by excessive mental stress (Franco and Fusetti, 2004).
