A device (7) for the rehabilitation of the movements of the foot (1) includes a supporting base (8) and a mobile platform (9) with a supporting surface (10) for resting the sole of the foot (1), wherein the mobile platform (9) is secured to the supporting base (8) by a pure rotation movement mechanism (12) with three degrees of freedom of rotary movement independent the one from the other and placed in parallel which allow rotations of the mobile platform around three axes (13, 14, 15) which intersect one another in a single rotation center (P). The supporting surface (10) is turned towards the rotation center (P) and is distant from the rotation center (P) in such a way that the rotation center (P) is positioned in correspondence to the ankle (2) of the foot (1).
