Preliminary design of a novel kinematic forearm model for pro/supination motion

Abstract

Forearm rotation is used in many daily activities, and its analysis may be needed for clinical, sports or robotic purposes. Therefore, modelling and simulation of the forearm motion is required. Due to its complexity, the forearm motion may be modelled in different ways. In this study, we proposed a preliminary design of a kinematic forearm model that will mimic pronation/supination (PS) movement in more realistic way. This model includes a moving rotation axis (MRA) about which the forearm rotates as PS motion. The results obtained from the preliminary design shows that rotating the arm around the MRA can give accurate and realistic hand location results. Furthermore, this model can be modified easily for subject-specific studies to obtain more accurate results. © 2020 IEEE.
