Research Abstract

With the aim of examining a preventive plan for musculoskeletal disorders caused by repetitive manual tasks, the effects of repetition frequency and work direction on the force of thumb push were investigated. The loads on each joint in the thumb were analyzed from the viewpoint of biomechanics. A prototype system for evaluating acceptable force limits in manual tasks was developed on the basis of the analysis results.
