Abstract

Apparatus for mobilising a human ankle joint comprising a base (2) having an upper surface shaped to receive a foot with its heel adjacent the rear of the base and toes towards the front of the base, and a strap (4) extending from points adjacent the rear to form a loop extending towards the front, the loop being sufficiently long when a foot is in the base to pass around the ankle at the talo-crural joint, the left side of the upper surface having an upwardly-extending protrusion (PL) shaped to provide medial arch support to the arch of a right foot and the right side having a second upwardly-extending protrusion (PR) shaped to provide medial arch support to the arch of a left foot, the upper surface of the base between the protrusions being lower than the protrusions to support the foot's lateral edge, to resist inversion or eversion of the foot during dorsiflexion.
