Design And Implementation Of An Assistive Device For Evaluating Rehabilitation In Stroke Patients With Limited Mobility During The Application Of Constrained Induced Movement Therapy

Abstract

A stroke, also known as a cerebrovascular accident, happens when there is an obstruction of blood flow to a specific region of the brain or when a blood artery in the brain ruptures. Regardless of the scenario, certain regions of the brain sustain damage or perish. A stroke has the potential to result in permanent brain damage, chronic disability, or fatality. Every year, a staggering 15 million individuals globally experience a stroke. Out of these, 5 million individuals perish and an additional 5 million are left with enduring disabilities, imposing a weighty responsibility on their families and communities. Within the framework of Constrained Induced Movement Therapy, this study suggests that utilizing the Modified Ashworth Scale method to monitor and evaluate gloves for Hand Rehabilitation can enhance assistance and rehabilitation efforts in a home setting. Baseline data collected can help doctors choose the better treatment for the patient. Extracts angular velocity data from the Inertial Measurement Unit (IMU) and displays it in units of radians per second (rad/s) or degrees per second (°/s). Angular velocity data from the IMU can be used to compute indices or convert data for assessing the degree of spasticity MAS. The results will be assessed based on the angular velocity levels correlating to the finger movement on a scale from 0 to 4, with each level indicating varying degrees of spasticity. Spasticity level can impact the speed and range of finger movement. Elevated muscle tension can lead to an increase in angular velocity, causing irregular variations in angular velocity data when performing movements.
