Abstract: The present invention relates to a magnetic therapy and a physiotherapeutic device performing such a magnetic therapy. The therapy involves the application of magnetism which provides a transient penetration of magnetic flux by means of a magnetic field scanning of a whole human body or a portion thereof in a three-dimensional gradient magnetic field. The physiotherapeutic treatment device comprises (1) a bed; (2) two magnets straddling on either side of the bed; (3) a mechanical-electrical transmission system; and (4) an electric control system. Therapeutic and health-care effect is achieved by means of magnetic field scanning of the human body with the body lying on the bed facing upward while the two magnets, at properly adjusted heights and actuated by the control panel, move horizontally along the human body receiving the treatment. Clinical tests demonstrate that this invention has remarkable therapeutic effects upon the treatment of a variety of disorders.
