Robot-Assisted Therapy For Stroke Rehabilitation

Abstract

The current study aims to create a hybrid exoskeleton robotic manipulator for stroke patients' upper limb rehabilitation.  A hybrid manipulator made up of two parallel manipulators coupled in series makes up the robot.  It combines the capabilities of a bottom 2-SPR (Spherical-Prismatic-Revolute) parallel manipulator and an upper 3-SPS (Spherical-Prismatic) parallel manipulator. This robot is four-degree-of-freedom (d-o-f) based on rehabilitation motions it will provide. The intention is to offer two motions for wrist joints and two motions for elbow joints as robot therapy. Wrist flexion/extension, ulnar/radial deviation, elbow flexion/extension, and pronation/supination are among the actions that the robot is made to enable.  End-effector and exoskeleton technologies have the potential to improve hand motor function in chronic stroke patients, producing outcomes that are on par with or better than those of conventional therapy.  As a potential strategy to improve recovery results, robot-assisted therapy is becoming more widely acknowledged as a beneficial addition to traditional rehabilitation techniques for enhancing motor function in stroke patients.
