The rehabilitative activity in VRRS is an active interaction between the computer and the user. One only physiotherapist can assist multiple users at the same time and regardless of their location. Therefore, a high intensity rehabilitation can be performed (minimum one hour per day), allowing the user to perform the tasks independently with a direct verification of the results. The intensive repetition of the exercises is an important step in motor learning, as can be easily understood in the daily practice of those who dedicate themselves to the use of instruments, such as music, where the accuracy and correctness of quick and precise acts is critical. The remote verification of the permanence of the results achieved through motor learning with VRRS system encourages the diffusion of the system, not only for the cost effectiveness.
