The PS consists of a standard laptop with a specifically created for the rehabilitation REWIRE platform and pre-installed software (Università degli Studi di Milano, Italy, Applied Intelligent Systems Laboratory Department of Computer Science). In the context of a training system connected to the computer, the software enables the collection of data, which are recorded as part of the training. In this study only exercises for balance ability are part of the training program. The training system consists of a so-called Tymoplate® (Tyromotion, Austria), a medical device class 1 with CE certification and approval by the FDA for use in neurorehabilitation after stroke. The Tymoplate® is connected to the computer and allows by means of a base plate with integrated pressure sensors and custom-developed training software, various postural biofeedback exercises. In combination with 3D cameras (Kinect®, PrimeSense, CA, USA), the patient sees him-/herself or an avatar in real time on a screen which moves in the virtual training environment. By various, attractive and entertaining designed training games as well as provided audio-visual feedback and balanced score system, patients should be maximum motivated to exercise.
