• (a) a frame;
• (b) a load member movably supported by the frame and having a load attachment point for movably carrying a limb portion of the patient, the load member comprising a wheeled carriage, the frame including track means for rollably guiding the carriage;
• (c) drive means for repetitively cycling the load member in a carriage path relative to the frame, the drive means comprising:
• (i) a first crank member and motor means for driving the first crank member;
• and
• (ii) a first rigid connecting rod pivotally connected to the first crank member for reciprocating the carriage along the track means;
• (d) base means for supportively anchoring the apparatus, comprising a clamp member for clamping to an external hoist arm, and a lift attachment member for supportively connecting an extremity of the hoist arm;
• (e) pivot means for adjustably orienting the frame in a fixed position relative to the base means, the pivot means having a first position for horizontally orienting the track means for lateral movement of the limb portion and a second position for vertically orienting the track means for raising and lowering the limb portion;
• (f) a platform member, the frame being supported by the platform member, the lift attachment member being fixably located relative to the platform member, a clamp arm pivotally connected between the clamp member and the platform member, and clamp lock means for fixably locating the clamp arm in a plurality of angular orientations relative to the platform member.
