An Inertial Sensing System for Upper Limb Motion Monitoring in Neurorehabilitation |Biomedgrid

Upper limb motion monitoring is vital in understanding upper limb recovery for patients who are undergoing neurorehabilitation. In recent years, there has been a growing interest in developing wearable sensing systems for human motion monitoring. In this paper, an inertial sensing system has been proposed for monitoring upper limb motion. Range of motion and position of upper limb segments are the two most important measures in assessing upper limb motion. Measurement of the range of motion of upper limb segments is based on the 3D orientation output from inertial sensors. Experiments have been done on different volunteers to evaluate the accuracy of the range of motion measurement. Kinematic modelling is based on multiple sensors and can accurately estimate the position of upper limb segments. Trajectory tracking has been done based on the position estimation results from kinematic modelling. The experimental results show that additional useful information can be obtained by using the proposed inertial sensing system.
