Professional Brain Injury Service Hospital NISA Valencia al Mar and Seville Alcor in collaboration with members of the Laboratory of Human Centered Technologies (LabHuman) of the Technical University of Valencia has designed and developed a virtual reality system supported specifically designed to arm rehabilitation in hemiparetic subjects. Demonstration of operation of the system. Systems based on virtual reality (VR) environments provide very favorable for neurorehabilitation, allowing to simulate aspects of everyday life while and stimulus parameters are set based on the characteristics of each patient. As part of the research undertaken through the Programme for Research and Technological Development 2011 Impiva, Professional Brain Injury Service NISA Hospital and Laboratory of Human Centered Technologies (LabHuman) of the Technical University of Valencia have developed a tool based virtual environments specifically for the rehabilitation of the paretic arm. "The system relies on the use of the Microsoft Kinect device. Using this technology, it detects that the subject makes motions with his arm as he develops in virtual scenes designed "says Roberto Llorens, chief project by Labhuman. To regain the upper limb function, training mustactive and intensive. Movements must be geared towards specific exercises that provide a meaningful and insist on the use of the arm in bimanual activities. "No clutch, must take into account that the mobility is very uneasy, and in most of the cases, it is impossible to exercise the desired tasks in the real world with real objects," says Carolina Colomer, rehabilitation physician Brain Injury Service NISA Hospital. To overcome this disadvantage, the VR system designed by professionals and Brain Injury Service Labhuman allows the projection of various scenes that simulate real environments, which is proposed to perform a specific task with the arm. The virtual environment interacts with the patient modified according to the movements that the subject does, so that, depending on how your year is achieved or not the proposed task. Being objects and environments that simulate everyday activities such as cooking, playing the piano, buy objects etc., gives a functional sense the repetition of movements. "This way we can encourage active implementation motor acts that want to train" explains Enrique Noah neurologist service. It also provides controlled and accurate information about the result of the movements, which helps to reinforce the exercise. These aspects, along with entertaining and motivating this type of training, facilitatesrelearning arm movements. Professionals and experts in rehabilitation of patients with brain damage Brain Injury Service Hospital NISA, have extensive experience in the design and use of virtual environments for motor and cognitive rehabilitation. The service manager, Joan Ferri says that "with the close supervision and individual adjustment of the parameters by the clinician, this tool allows enhance recovery of arm function of patients."
