Possibility of Using a VR System as an Action Observation Therapeutical Technique

In recent years, 3D virtual reality (VR) systems are increasingly finding their way into biomedical applications. Nevertheless, in most cases a 3D VR is being used as an interactive system (such as Xbox Kinect or Playstation VR). These interactive systems, however effective they may have proven, not only limit use of 3D VR in patients incapable to engage in these systems due to their physical or mental disability, but also put significant requirements on medical institutions for an equipment, medical personal, and therefore institutional budget. In this article, we are proposing a 3D VR as an stand-alone action observation training device, which could limit requirements associated with abovementioned interactive systems due to its capability to stimulate a mirror neuron system of human brain, while adding minimal demands on both patient and medical facility. Research studies that confirm activity in the motor cortex will be described. We focus on the literature that describes theories, models, and experimental studies dealing with the effects of motion observations that are involved in the control and final performance of motor skills.
