Abstract:
1. A pulsed electromagnetic field therapy apparatus for treatment of a joint affected by osteoarthritis, comprising: a wearable applicator configured to be disposed adjacent to the joint receiving therapy; a plurality of electromagnetic coils provided to the applicator and configured to generate an electric field and a magnetic field within a treatment volume of the joint, the plurality of coils arranged such that a dead zone within the treatment volume where the electric field is below a minimum therapeutic value through an entire cycle of energizing the coils is precluded, the coils further arranged relative to the joint such that the magnetic field generated within the treatment volume is directed substantially normal to a cartilage layer of the joint and that the electric field is oriented substantially parallel to the cartilage layer of the joint; a switching board functionally connected to the plurality of electromagnetic coils, the switching board configured to activate the plurality of electromagnetic coils in a predetermined sequence; a processor functionally connected to the switching board; and a power source electrically connected to the switching board.
