Innovative Solutions for Tetraplegia: A Smart Hand Orthosis Design

Abstract

Spinal cord injury (SCI) poses a significant medical challenge, affecting both hand dexterity and locomotor abilities. Ongoing advancements in medical technologies, spanning a spectrum of wearable devices, coupled with concurrent progress in rehabilitation treatments, aim to enhance hand function among individuals affected by SCI. The emergence of three-dimensional (3D) printing provides a cost-effective avenue for crafting personalized devices, fostering a surge of interest in integrating this technology with rehabilitation equipment, thereby complementing advancements in scientific research. Myoelectric control plays a pivotal role in achieving enhanced rehabilitation outcomes. It involves the detection and processing of weak electromyographic signals (EMG) from affected limb muscles to activate orthotic motors. A novel 3D-printed hand orthosis, responsive to electromyography signals, has been developed to facilitate grasping functionality in cervical SCI patients.
