Apparatus for continuous passive articular mobilization of the foot
First Claim
1. Apparatus for passive articular mobilization of a foot, comprising:
- a base;
a sole element;
articulation means for supporting the sole element upon the base for independent articulation about three orthogonal axes comprising a varus-valgus axis (B--B'"'"') extending generally perpendicular to the base, a flexion axis (A--A'"'"');
an abduction-adduction axis (C--C'"'"') intersecting both the varus-valgus and flexion axes and extending generally parallel to the base;
a single reversible drive motor mounted on said base;
a transmission means mounted on said base for connecting the drive motor to the sole element and for reversibly moving the sole element selectively and simultaneously about said three orthogonal axes in response to motor actuation with the moving of the sole element being independently variable, relative to motor actuation about said three orthogonal axes and wherein the movement of the sole element about any of the three orthogonal axes in response to motor actuation is adjustable to zero motion;
said transmission including a carriage supported on the base, said drive motor moving said carriage rectilinearly generally parallel to said base.

Abstract
Apparatus for passive articular mobilization of a foot includes a sole element mounted on a base for articulation about three independent orthogonal axes including a varus-valgus axis extending generally perpendicular to the base, a flexion axis, an abduction-adduction axis intersecting both the varus-valgus and flexion axes and extending generally parallel to the base. A single reversible drive motor is mounted on the base and is attached to the sole element by a transmission system including levers for reversibly moving the sole element selectively and simultaneously about the three orthogonal axes in response to motor actuation. The transmission system includes a movable carriage that can be driven rectilinearly or rotatably relative to the base. The effective length of the levers is adjustable so that, upon actuation of the motor, the sole element can be adjusted to a desired corrective position.
