Development of a biomechanical model for the analysis of the wrist extension and flexion movement

Abstract

The wrist links hand and forearm to each other and it allows movements in two different planes. Thus it has an important role in the mobility of the hand. In previous studies, researchers have analysed the movement of the wrist joint using different mathematical models and methods. In this study, the hand and the wrist have been modelled as a simple pendulum in the sagittal plane. MATLAB&Simulink-based SimMechanics software was used for this process. The joint torque of the wrist during extension and flexion movement of the hand was calculated using motion analysis data. It has been found that the SimMechanics model given useful results.
