System Overview

The Rehabilitation Gaming System (RGS) is a novel and highly innovative ICT Virtual Reality (VR) tool for the rehabilitation of motor deficits of the upper extremities after a brain lesion due to stroke. The system deploys an individualized game training that combines movement execution with the observation of a correlated action by virtual limbs that are displayed in a first-person perspective.

The Rehabilitation Gaming System.  A subject sits facing a screen  and with his/her arms on a table, . Arm movements are tracked by a Kinect sensor mounted on top of the display. The tracking system determines in real-time the position of the user's wrists, elbows and shoulders, and maps these onto a biomechanical model of the upper extremities. On the display two virtual arms mimic the movements of the subject’s arms, hands and fingers.

The RGS is based on the neurobiological considerations that brain plasticity remains throughout life and can thus be utilized to achieve functional reorganization of areas affected by stroke by means of  activation of secondary motor areas such as the so called mirror neurons system. As a multi-level adaptive tool, the RGS provides a task oriented game training with individualized graded complexity. Additionally, the system retains qualitative and quantitative information of the performance of the subject/player during the tasks, hence allowing for a detailed assessment of the deficits of the patient player and their recovery dynamics. The RGS approach has been evaluated in different randomized clinical studies and the results have demonstrated positive impact.

As an example, the video above shows the RGS system at work in recent experiments in home environments . Results of this research, as well as more elaborate videos of the system's aspects will follow soon.

 

Why to use RGS?

  1. Because it is designed and deployed as a portable at home complete rehabilitation.
  2. Because it provides personalized cognitive and functional rehabilitation.
  3. Because it assesses the patients status and progress using predictive models to provide prognosis and generate individualized rehabilitation protocols.
  4. Because UPF (Pompeu Fabra University) has recently shown in two randomized clinical studies that patients in the acute as well as the chronic stage of stroke profit from therapy paradigm RGS pursues.

Currently the RGS system is deployed in a number of hospitals with positive outcomes on rehabilitation. The RGS@home system for individualized training in the home environment is being developed and tested and will be ready in the near future.

Which are the requirements to start training with the RGS?

  1. The RGS software.
  2. A common computer.
  3. Motion sensor and tripod.
