Skeletal modeling, analysis and simulation of upper limb of human shoulder under brachial plexus injury

Abstract

This article presents the skeletal-mathematical model and a measurement system for providing real-time information related to position, angular velocity, and orientation of different movements related to the upper limb of human shoulder using Inertial Measurement Units (IMU). The main goal of this system is to improve the rehabilitation tasks of unilateral brachial plexus injury, therefore a complete kinematic analysis of the shoulder skeletal system, considering only the essential variables to simulate the movements used in rehabilitation, is detailed. Finally, are presented some experimental tests based on joint physiology and biomechanics of human shoulder for children less than 10 years, according to desired restriction of medical staff belong to Hospital Infanta Sofía of Madrid.
