Evaluation of a robot-assisted rehabilitation system with assist-as- needed and visual error augmentation training methods

摘要

This paper presents the evaluation of a robot-assisted rehabilitation system with assist-as-needed and visual error augmentation training methods. In this robot-assisted rehabilitation system, an assistive controller provides robotic assistance to the participant as and when needed. In addition, the position errors that are visually fed back to the participant are amplified to heighten the participant's motivation to improve tracking accuracy. Experimental results on unimpaired participants are presented to demonstrate the efficacy of the enhanced rehabilitation robotic system.
