Abstract

A method of treatment including positioning the part of the patient or animal to be treated between the poles of an electromagnet. The part is then subjected to a pulsating magnetic field induced in the electromagnet by an intermittent direct current, the peak intensity of each pulse being at least 2,000 gauss. Preferably each pulse has a duration of at least 1/4 second, and about one pulse per 1/2 second is administered.

Claims

1. The method of treating a living thing or part thereof, which comprises positioning so As to expose at least a part of said living thing in proximity to the pole face of an electromagnet, said electromagnet having at least one pole face, causing an intermittent direct current to flow through said electromagnet so as to produce an intermittent magnetic field at said pole face having a field density of at least approximately 2,000 gauss at the peak of each pulse, and simultaneously regulating the frequency of the intermittent direct current to produce magnetic impulses at a frequency of less than 1 impulse every 1/2 second, each said impulse having a duration of at least 1/4 second.

2. The method as set forth in claim 1, said field being induced between the pole faces of an electromagnet, and including the step of controlling said intermittent direct current flow to provide said magnetic field having a field density of at least approximately 2,000 gauss at the pole faces when the pole faces are 4 in. apart.

3. The method as set forth in claim 1, including the step of controlling the direct current so that the magnetic field density in gauss declines to a zero value between the peak gauss points of successive pulses, causing the intermittent direct current to flow through said electromagnet in such manner so as to produce an intermittent magnetic field of approximately 5,000 to 7,000 gauss magnetic field density, and applying from 100 to 1,000 impulses having a peak duration of about 1/2 second at a frequency of one every 4 to 10 seconds.

4. The method as set forth in claim 1, including the steps of positioning a selected site of said part between two pole faces of an electromagnet, causing the intermittent direct current to flow through said electromagnet in such manner so as to produce an intermittent magnetic field of about 3,600 gauss flux intensity, applying about 100 1/2 -second duration impulses to said selected site over a period in the range of from 1 to 3 minutes, and repeating the foregoing 100 1/2 -second impulses on said selected site up to approximately 9 times in 3 hours.
