1. A head, neck, and shoulder therapeutic exercise device comprising:

  • a frame;

    an electric motor assembly supported on said frame, said assembly comprising a motor having a shaft and means for reducing the rotational speed of said shaft;

    back head rest means for restricting the backward movement of a patient'"'"'s head during treatment;

    means for implementing or assisting the backward and forward movement of a patient'"'"'s head during treatment, said means for implementing or assisting including a cam, said cam mounted on said shaft;

    a roller bearing plate housing a roller bearing, said roller bearing positioned to be in contact with the outer edge of said cam;

    means for restraining the forehead and chin of a patient to said roller bearing plate;

    a roller block assembly for selectively positioning said back head rest means to be in contact with the back of a patient'"'"'s head during treatment, and for facilitating the backward and forward movement during treatment of said back head rest means and said roller bearing plate, said back head rest means and said roller bearing plate being affixed to aid roller block assembly;

    a timer for selectively and cyclically stopping and restarting said motor during treatment;

    wherein upon motorized rotation of the shaft, the high side of the cam contacts the roller bearing causing the roller bearing plate to move away from the patient'"'"'s head thereby tensioning the means for restraining the head, whereupon the timer briefly stops the motor leaving the roller bearing plate in retracted position until the motor restarts causing the high side of the cam to rotate out of contact with the roller bearing thereby allowing the roller bearing plate and means for restraining the head to return to original position.
