[Medical surveillance and occupational identification of workers exposed to repeated movements of the upper limbs].

Repetitive motions of the upper limb at work can induce muskulo-skeletal alterations, therefore a specific medical surveillance is needed, according to the intensity of risk. In low risk conditions, the medical surveillance is aimed at the identification of hyper-susceptible individuals and the administration of specific information programs. When the risk intensity is higher, medical surveillance should add the recognition of early symptoms and signs of muskulo-skeletal disturbances, in order to remove workers showing early alterations from the exposure and allow medical rehabilitation. The diagnostic protocols with the adequate instrumental evaluation are provided, and the required legal reporting is discussed.
