Application of simple kinematic model from flexion movement of upper-limb with RGB-D camera perspective

Abstract

This study describes the use of an RGB-D camera for the assessment of the upper-limb movement for stroke rehabilitation patients. The assessment process is carried out by making comparisons between patient movements and simulated movements. The motion simulation is modelled by the kinematics model of the 6 DoF arm with extended flexion motion. Tests were carried out on 13 normal patients with movement schemes that often appear in the rehabilitation process. The results show that the use of the 6 DoF model results in better accuracy and calculation time than using the 8 DoF model.
