Multifunctional Exoskeletal Orthosis for Hand Rehabilitation Based on Virtual Reality

Abstract

Within the field of physical rehabilitation in patients with fine motor deficits due to tendon injuries, this article is a novel proposal for the treatment and recovery of hand mobility. The mechanism works within virtual environments designed according to the needs of the beneficiary, through a mechatronic prototype controlled by algorithms based on fuzzy logic, the data sent by the Unity3D graphics engine and bending sensors is verified. The results of this system are focused on the process of digital signals for activation of the force feedback mechanism, this is done through the use of a flexible orthosis that allows the flexion and contraction of the fingers of the hand, thanks to this, excellent control results and an adequate performance in the development and execution of the proposed tasks in the virtual environment are obtained in a way that significantly promotes and improves the quality of life of the user.
