ABSTRACT
The OCcupational Repetitive Actions (OCRA) system analyzes awkward postures as one of a range of risk factors. It looks at the main joint segments of both the left and right arms, defines at-risk postures, and assigns different scores based on the region of the limb involved and the duration of the posture. This chapter shows how the Timing Assessment Computerized Strategy (TACOs) method is applied to an additional timing analysis of the postures, for example, of the back, lower limbs, and head/neck. The procedure, entailing the use of a specific Excel spreadsheet, is described in detail in the relevant table. For studying the task in terms of the risk of biomechanical overload, whether the job is full time or part time, it is always necessary to match the scores obtained with the OCRA checklist with those obtained with the TACOs method.
