Device for the rehabilitation of foot movements, said device comprising: - a supporting base for resting or fitting the device on an application environment, - a mobile platform with a supporting surface for resting the sole of the foot and securing means configured for securing the foot to the mobile platform, - a movement mechanism which constrains the mobile platform to the supporting base and which can be operated to move the mobile platform in pure rotation with three degrees of freedom of rotary movement around axes (13, 14, 15) intersecting one another in a single point forming a rotation centre, wherein the movement mechanism comprises three articulated links (16, 17, 18), each of which connects the mobile platform to the supporting base, said three articulated links (16, 17, 18) being arranged in parallel relationship to one another, wherein each articulated link (16, 17, 18) comprises: - a first rigid segment secured to the supporting base by means of a first joint in a rotatable way and actuatable in rotation by an actuator around only one first rotation axis (13, 14, 15) which passes through the rotation centre, relative rotations around axes other than the first rotation axis and any relative translation between the first rigid segment and the supporting base being prevented, - a second rigid segment secured to the first rigid segments by means of a second intermediate joint in a rotatable and idle way around only one intermediate articulation axis which passes through the rotation centre, relative rotations around axes other than the intermediate articulation axis and any relative translation between the second rigid segment and the first rigid segment being prevented, - a third joint securing the second rigid segment to the mobile platform in a rotatable and idle way around only one third articulation axis which passes through the rotation centre, relative rotations around axes other than the third articulation axis and any relative translation between the mobile platform and the second rigid segment being prevented, wherein the supporting surface of the mobile platform is facing towards said rotation centre and is distanced from the rotation centre in such a way that the rotation centre is positionable at the ankle of the foot resting on the supporting surface. - a supporting base for resting or fitting the device on an application environment, - a mobile platform with a supporting surface for resting the sole of the foot and securing means configured for securing the foot to the mobile platform, - a movement mechanism which constrains the mobile platform to the supporting base and which can be operated to move the mobile platform in pure rotation with three degrees of freedom of rotary movement around axes (13, 14, 15) intersecting one another in a single point forming a rotation centre, - a first rigid segment secured to the supporting base by means of a first joint in a rotatable way and actuatable in rotation by an actuator around only one first rotation axis (13, 14, 15) which passes through the rotation centre, relative rotations around axes other than the first rotation axis and any relative translation between the first rigid segment and the supporting base being prevented, - a second rigid segment secured to the first rigid segments by means of a second intermediate joint in a rotatable and idle way around only one intermediate articulation axis which passes through the rotation centre, relative rotations around axes other than the intermediate articulation axis and any relative translation between the second rigid segment and the first rigid segment being prevented, - a third joint securing the second rigid segment to the mobile platform in a rotatable and idle way around only one third articulation axis which passes through the rotation centre, relative rotations around axes other than the third articulation axis and any relative translation between the mobile platform and the second rigid segment being prevented,
