Combining Immersive Virtual Environments with Robot-Aided Gait Training

摘要

While robotic rehabilitation devices are gaining popularity in research and clinical use, a possible drawback of these devices is the reduced physical interaction between the therapist and the patient compared to manual training. To compensate for this lack, the device has to assess the patient's movements and provide (bio-)feedback to the patient. Furthermore, it could deliver instructions and increase motivation. The design and implementation of an immersive virtual environment for robot-assisted gait training are described that delivers feedback and increases motivation. Subjects can navigate through exchangeable virtual environments by modulating their performance of the left and right leg. Preliminary tests show usability with control subjects. Clinical tests are still required to show applicability in the clinical routine and to test for therapeutic efficacy.
