Proprioception is the ability to sense the position of the muscles, and the relative position among contiguous body
parts. In the game developed for this paper, the sight is blocked when the patient wear the virtual reality glasses, so
he is unable to see himself moving his upper trunk. This hardens some tasks such as motion coordination, automatic
body responses and awareness of self-position across the space. As a result, extra effort must be done by other
sensors, which according to experts17,18 might accelerate the treatment and increase its effectiveness.
