Abstract
A method and apparatus comprises a circuit adapted to be coupled to a power supply which produces a pulsed DC output, and a magnetic field generating coil coupled to the output of the circuit which is effective to produce a time varying magnetic field having a flux density in the range of about 0.0001 to 2.0 gauss at a frequency in the range of about 0 to 45 Hz. The coil is positioned at or near the site on the body of the patient to be treated, or, alternatively, beneath the patient's sleeping surface for a period ranging from about one-half hour to several hours depending upon the method and condition to be treated.
