A therapy device includes a frame, a motor, and a sling on which a neck of a supine user rests. The sling is movable by the motor relative to the frame to enable continuous passive motion rotation of a user's neck and cervical spine. Additionally, depending on where the user's head is placed relative to the sling, the user's spine can be placed in axial traction, and the user's neck can also be placed into extension. Movement of the sling may be achieved by an armature that is rotated by the motor. The armature may include a plurality of openings formed therein that are configured to receive a sling lead. Each of the openings results in a different amount of rotational movement of the user's head, such that a user can adjust to location of the sling pin to result in a desired amount of rotational movement.
