Abstract: The invention provides for an apparatus for performing physiotherapy, in particular, it provides an apparatus for stretching the hind leg muscles in isolation from the other muscle groups. In accordance with the invention, the apparatus comprises a seat and backrest mounted to a base. Further, a moveable swing arm with a heel pad at the end is pivotally attached to the base. The swing arm is actuated by actuation means such that the heel pad moves in an arc. In use the user sits on the seat and places their heel on the heel pad. In the initial position the user's leg is bent. The swing arm is then moved to a position whereby the users leg is substantially straight. The leg is held in the straightened position for a period and then is returned to the bent position. The actuation means can be a manually operated hydraulic pump.
