T0 assessment, the VRRS system was delivered to her home. The training was planned for three months, with daily activities lasting 40 to 50 min, organized in different exercises (with different goals); the girl was asked to perform the training for a minimum of three days per week (Figure 1).
On the (left), the setting of the home training with the VRRS HomeKit (A) and the stabilometric balance (B). On the (right), some examples of the proposed exercises: (1) Reaching points (R), (2) Reaching and (3), (4) two exercises of 3D environment.

T0 evaluation, tailoring the training according to the patient's functional skills and the goals to be achieved.
