ABSTRACT
Working tasks that require manual repetitive actions at high frequency may cause the risk of fatigue, discomfort, and musculoskeletal disorders. A proper risk assessment and management should seek to minimize these health effects by taking into account a variety of risk factors including, in relation to the duration of exposure, the frequency of actions, the use of force, the postures and movements of the body segments, the lack of recovery periods, and other additional factors (Colombini et al., 2001).
