Virtual Rehabilitation System for Fine Motor Skills Using a Functional Hand Orthosis

Abstract

This article describes a virtual rehabilitation system with work and entertainment environments to treat fine motor injuries through an active orthosis. The system was developed in the Unity 3D graphic engine, which allows the patient greater immersion in the rehabilitation process through proposed activities; to identify the movement performed, the Myo armband is used, a device capable of receiving and sending the signals obtained to a mathematical algorithm which will classify these signals and activate the physical hand orthosis completing the desired movement. The benefits of the system is the optimization of resources, infrastructure and personnel, since the therapy will be assisted by the same virtual environment, in addition it allows selecting the virtual environment and the activity to be carried out according to the disability present in the patient. The results show the correct functioning of the system performed.
