[Plastering: assessment of risk for upper limb biomechanical overload and of energy expenditure]. / L'attività di intonacatura manuale: valutazione del sovraccarico biomeccanico degli arti superiori e del dispendio energetico.

ABSTRACT

This work analyzes the activities carried out by a plaster construction worker, describing the data obtained from the assessment of risk for upper limb biomechanical overload, through the application of checklist and the OCRA method, and the operator's energy expenditure, measured using portable calorimeter. By analyzing the pattern of energy expenditure in relation to the actions performed we observe a direct correlation between posture, force employed, and metabolic rate. The activity of plastering involves biomechanical overload of upper extremity and high energy expenditure.
