Abstract

Effect of Robot-Assisted Training on EEG-Derived Movement-Related Cortical Potentials for Post-Stroke Rehabilitation–A Case Series Study

Highlights

According to the recent annual report of the World Stroke Organization, approximately 14 million people had their first-time stroke each year and 80 million people live with the impact of stroke globally [1]
The averaged pre- and post-training movement-related cortical potential (MRCP) signals at all selected electrodes (ILFC, ipsilateral C (ILC), ipsilateral CP (ILCP), contralateral FC (CLFC), contralateral C (CLC), contralateral CP (CLCP), Cz, and CPz) for group A and group B are shown in Fig. 3 and Fig. 4, respectively
The MRCP signals at all electrode sites are plotted for the time interval -1s to 1s for better visualization of the amplitude changes that occurred in MRCP Npeak after completing multi-session motor training

Summary

INTRODUCTION

According to the recent annual report of the World Stroke Organization, approximately 14 million people had their first-time stroke each year and 80 million people live with the impact of stroke globally [1]. Some other studies reported a decrease in the amplitude of the MRCP after the subjects achieved competency in motor tasks with practice [21]–[24] All these studies demonstrate the effects of various motor training protocols in healthy participants on the MRCP signal. These studies overlook the factor of stroke lesion location during motor training design and analysis of the results, though several authors reported that the post-stroke recovery depends upon the lesion location [35]–[40]. This paper reports a study conducted to investigate the variation of MRCP during motor training for post-stroke patients. Variations in MRCP features were associated with improvements in the hand motor skills of the patients This innovative study provides a significant contribution to post-stroke rehabilitation research.
