Modified Technology for a New Generation Stroke Rehabilitation Module by Transcutaneous Vagal Nerve Stimulation Therapy − A Critical Analysis

Abstract

An important goal of stroke rehabilitation is to improve the quality of life, enhancing functional independence, and active participation in daily routine activities. Stroke is a cerebral vascular event with rapidly developing clinical signs of global disturbances with no apparent cause other than a vascular origin. A stroke occurs when the blood vessels in the brain are blocked or burst, which prevents the blood and oxygen from reaching brain tissues. Symptoms of stroke in body parts are controlled by damaged areas of the brain and the main symptoms show involuntary muscle tightening, paralysis, and restricted physical abilities. Other complications depend upon the damage to part of the brain. Enhancing plasticity by triggering neuromodulators with paired motor training provides the basis for transcutaneous vagal nerve stimulation (TVNS) therapy. TVNS to activate the neuromodulatory networks of cortical neurons shall be achieved by the battery-powered device with electrodes and adhesive backing which can be positioned on the skin in specific areas. The device delivers electrical impulses which activate the vagal nerve and enhance the plasticity of cortical neurons. This article emphasizes vagal nerve stimulation paired with rehabilitation therapy, which combines a device that stimulates vagal function which promotes motor function, and rehabilitation training to facilitate a speedy recovery. This technology is precise and consistent in developing pro plasticity neuromodulators and improves the daily performance of the affected individual.
