[Repetitive movement of the upper limbs: results of a current exposure evaluation and a clinical investigation in workers employed in the preparation of pork meat in the province of Modena].

Exposure assessment tests were undertaken to measure the biomechanical overload factors affecting the upper limbs. The tests were carried out on a group of 86 workers employed on the cutting, boning and trimming line of a pork meat processing plant. Anamnestic screening and clinical tests targeted at correlated disorders were also performed and were followed by instrumental tests. The results are reported with respect to frequency of repetitive technical actions, degree of muscular involvement, postural risk, several complementary factors and distribution of recovery periods. The clinical investigation showed a high prevalence of carpal tunnel syndrome, tendon disorders of the hand and epicondylosis of the elbow, in addition to other disorders. The report confirms the presence of additional risks for the workers, both in the past and under present circumstances, and suitable preventive measures are formulated.
