Poster V17 - Designing an Exo-Suit for Post Stroke Recovery using Robot Assisted Mirror Therapy

Introduction: Stroke is the third leading cause of long-term disability globally, often resulting in significant limb impairment, which can severely impact quality of life and mental health. Effective rehabilitation is crucial for regaining limb function and Recovery hinges on effective rehabilitation, yet many patients face barriers due to costly, non-portable market options and limited access to therapy centers. To address these issues, we developed a lightweight, wearable device for upper body that is easy to manufacture using readily available parts, enabling at-home rehabilitation utilizing Robot Assisted Mirror Therapy (RAMT). RAMT employs visual feedback and neuroplasticity to improve motor function and reduce pain in stroke patients.

Materials and

Methods: The developed design uses RAMT technique. It detects the healthy upper limp movements and utilizes a robotic part to apply that exact movements on the paralyzed upper limp. It is a portable wearable system that controls the movements of the shoulder and finger joints. Using 3D printed exoskeleton, Pulleys, linear actuators, and worm gear motors. Movements of the healthy upper limp are detected using flex sensors for fingers joints and accelerometer for the shoulder.

Results, Conclusions, and Discussions: The development of a lightweight, wearable device for at-home rehabilitation using RAMT has yielded promising initial results. The system, designed to replicate healthy limb movements with a 3D printed exoskeleton, pulleys, linear actuators, and worm gear motors, achieved a shoulder flexion range of 65 degrees and a finger response time of 0.57 seconds, demonstrating potential for aiding motor function recovery for stroke patients with upper limb impairments. However, variability in outcomes due to individual factors such as weight and height necessitates personalized assessments to ensure accurate and effective rehabilitation. These findings suggest that at-home rehabilitation could become a reality soon, although results may vary depending on individual characteristics, highlighting the importance of personalized assessments for precise measurements across different patient populations. Further research is required to refine the device's adaptability. This report will delve into the technical aspects that underpin the functionality and efficacy of this innovative machine.
