The working posture is part of the risk factors for the development of muscle-skeletal disorders. Compared to postural problems of the trunk and upper limbs, those related to the lower limbs have been so far undervalued in the context of preventive medicine and ergonomics. The risk assessment tools for the lower limbs posture are inhomogeneous and incomplete. The classification of postures, the quantification of the risk, the correlation with organizational and individual aspects, and interventions for the prevention and management of the risk are aspects yet to be explored.
