Teachers Biomedical Neuroengineering group of Miguel Hernández (UMH) University of Elche Nicolás García Aracil José María Sabater and have developed a new robotic rehabilitation system that adapts to the patient, and not vice versa, during the course of therapy machines.

The developed system detects through sensors and other physiological parameters of the robot, if the patient is relaxed because the therapy does not pose any challenge. In that case, the difficulty increases therapy and/or the support that the robot is decreased. If, however, the patient has a high level of stress during therapy, the system detects and reduces the difficulty of the same.

Each session rehabilitation robotics, artificial intelligence algorithms learn new system parameters patient who subsequently used to improve the system to adapt the therapy to the patient. That is, the rehabilitation robotic system "get to know" the patient better in each rehabilitation session.

The aim of the project was to advance the development of robotic, applied for assistance or rehabilitation of patients. These devices have been used in recent years for rehabilitation and assistance to patients with different pathologies, but none of them are dynamically adapted to the patient's progress during the course of therapy.

Therefore, in the Maat project the patient is monitored during the course of assisted therapeutic activity for a device and a number of parameters are dynamically modified, such as the difficulty level of the therapy, the degree of assistance provided by the robot or virtual reality system associated with the therapy. The change in real time during therapy of these parameters maximize the patient's motivation for making the same. Through this process, better results from the point of view of functional recovery of motor abilities losses due to diseases.

Today, advances have been made in the project are being completed to adapt to carry out various tests with patients with acquired brain injury in several public hospitals in the province of Alicante.
