Robotic Exoskeleton for Elbow Rehabilitation

Abstract

The movement Impairments of motor function as a result of neurologic injuries causes in disabilities 
motions of subjects for performing the activities of daily living.  The urgent need to regain the 
activities of daily living enabled the physiotherapists to perform considered exercises to recover the 
suffered patient's motions. This study aims to construct, and manufacture a robotic exoskeleton 
flexible, portable, comfortable and adjustable for a wide range of users to rehabilitate patients who 
suffer from spinal cord injury, stroke the rehabilitation concerned on elbow joints with 
comprehensively their one degree of freedom (1 DOF). The present exoskeleton offers a 
flexion/extension for the elbow. It is constructed using SoildWorks software program and 
manufactured with 3D printer technology using the polylactic acid thermoplastic material. The 
exoskeleton supports the home-based therapy. It is actuated using servomotors and controlled using 
the electromyography signal extracted from biceps muscles using myoware sensor for measuring 
muscle with angle data as an assistance of controlling using gyroscope sensor for measuring angle 
the controlling process using Arduino uno the exoskeleton was supported with visual by using 
Organic Light-Emitting Diode display(OLED).  The exoskeleton supports active-assistive mode of 
operation
