Apparatus for mobilising the ankle joint

An apparatus for mobilising a human ankle joint comprising:

• a base part having an upper surface with front and rear ends, and left and right sides, the upper surface being shaped and configured to receive and support a foot with its heel adjacent the rear end and toes pointing towards the front end, and
• a strap extending from two points adjacent the rear end to form a loop extending towards the front end, the loop being of sufficient length when a foot is received in and supported by the base part to pass around the foot and ankle at the talo-crural joint,
• in which the left side of the upper surface has a first upwardly-extending protrusion shaped and configured to provide medial arch support to the arch of a right foot when the arch of the right foot is positioned over the first protrusion and the right side has a second upwardly-extending protrusion shaped and configured to provide medial arch support to the arch of a left foot when the arch of the left foot is positioned over the second protrusion, the upper surface of the base part between the first and second protrusions being lower than the protrusions so as to support the lateral edge of a foot and to prevent lateral movement of the foot when the outer lateral edge of the foot is located on a lower part of the upper surface of the base part between the first and second protrusions and shaped and configured, in combination with the first and second protrusions, to support the foot and resist inversion or eversion during dorsiflexion of the foot.
