Progressive Rehabilitation in Stroke Patients Using EMG Controlled Exoskeleton

Abstract

The nervous system's interaction with other body parts and the environment to achieve desired and coordinated actions is known as motor control. It is a reflex and decision-based system that systematically regulates movement functions. If the contact is weakened or interrupted, a variety of neurological problems such as apraxia, tremors, and neurological and neuromuscular strokes may result. To improve hand function in stroke patients, new medical technology such as wearable gadgets and rehabilitative therapies are being developed. Because three-dimensional (3D) printing allows for the creation of low-cost, individualized devices, interest in applying this technology in rehabilitation equipment is developing in line with scientific discoveries. A novel electromyography (EMG)-controlled 3D-printed hand orthosis is demonstrated in this study. Force transfer is a major worry for these gadgets that are worn on the user's hand. The orthosis is designed to help stroke survivors recover their grip ability. As a result, active and passive devices can be utilized to perform a range of rehabilitation activities to regain or strengthen lost or compromised control while also improving strength, mobility, and motor conditions. Active devices are controlled devices used in rehabilitation to improve muscle function and restore appropriate biomechanics by providing stability, maintaining posture, and maintaining joint alignment. This device allows the wrist and fingers to move in specific directions depending on their degree of flexibility, allowing patients to do daily tasks more easily. Finger extension and flexion (hand opening and closing) and wrist extension are among the motions performed by stroke patients.
