Analysis of the relationship between the adoption of posture and the appearance of forced pain in upper limbs: a case study on the shoe industry

The shoe industry market in Brazilian have been affected by the entry of several Chinese footwear manufacturers, representing a disadvantage in competition in the sector. To minimize this impact, companies tend to increase productivity and work rate, which can lead to serious repercussions on worker health. In recent years the discussion on occupational diseases increased, because this disease can lead to a temporary or permanent incapacity of the employee, bringing negative consequences not only for this, but also for the company or institution where the same work. From this premise, this study used two tools for data analysis of pain reported by workers and amplitudes of forced movements performed by these and, consequently, risk of musculoskeletal injury (SCI). The Diagram of Corlett and Manenica is a tool used to capture the feeling of tender points reported by respondents. As for the evaluation of jobs was used OCRA, Occupational Repetitive Actions, which is a tool for assessment and analysis of risk factors associated with repetitive movements of upper limbs, by calculating an index of quality. In the end we compared the exaggerated range of motion of the upper limbs data, held by workers with reports of pain in every joint of these members, checking whether or not the relationship between two variables. The use of OCRA filtered within the set of observed positions, only those with a high level of repeatability, and therefore are likely to generate LME.The results showed that the relationship between the presence of movements in exaggerated amplitudes and therefore the implementation of awkward postures of the upper limbs, is related to the onset of pain in this body region, and to this end, prevention and pro-activity in description of work tasks are of great importance for the reduction of these types of pain professionals
