Analysis of risk for repetitive work using thermography sensory

Abstract

One of the recurrent problems in works that require repetitive activity this study was performed on a group of workers and the temperature of the wrist and elbows were taken by means of sensorial thermography with the objective. This study was performed on a group of workers and the temperature of the wrist and elbows were taken by means of sensorial thermography with the objective of verifying that if the work takes place causes a temperature difference between the wrists is more than 0.6 °C and remains for greater than 15 min periods, then the person’s risk for muscular fatigue and skeletal muscle damage occurrence is high. The temperature was recorded for 2.5 h approximately. Finally, the data obtained were analyzed by means of cubic spline. In all cases, a temperature increase by more than 0.6 °C was observed in 15-min lapses, in the wrist and elbows. The findings of the study show that repetitive work over long periods affects the muscle causing the development of musculoskeletal disorders.
