For sensation originating in a part of the body at or below, but remote from, the lumbar-sacral region, a first method comprises placing at least one source of magnetic flux in close proximity to the lumbar-sacral region and allowing the source to remain there until the desired effect is achieved. For sensation originating in the upper extremities, a second method comprises placing at least one source of magnetic flux in close proximity to the cervico-dorsal region and allowing the source to remain there until the desired effect is achieved. ## Claims ### Claim 1 A method for reducing transmission in a human body of sensation from a body part to the brain, said sensation originating in said body part, said body part being located below and remote from the lumbar-sacral region of the body, the method comprising the steps of: a) disposing at least one source of magnetic flux in close proximity to the lumbar-sacral region of the body;

and b) allowing said source to remain so disposed for a period of time sufficient to reduce transmission of said sensation from said body part to the brain. ### Claim 13 (depends on 12) The method of claim 12 wherein there are multiple said sources having a combined magnetic flux density from substantially 10,000 Gauss to substantially 75,000 Gauss. ### Claim 14 (depends on 12) The method of claim 12 wherein said source has a north-south magnetic axis and is disposed such that said north-south magnetic axis is substantially perpendicular to the surface of the body in the cervico-dorsal region. ### Claim 15 (depends on 14) The method of claim 14 wherein said source has a north pole which is directed toward the cervico-dorsal region. ### Claim 16 (depends on 12) The method of claim 12 wherein a plurality of said sources are arranged into an array by a supporting web having a smoothly curved inner surface, each said source having a north-south magnetic axis oriented substantially perpendicular to said inner surface of said web, said array being disposed such that said inner surface is substantially parallel to the surface of the body in the cervico-dorsal region. ### Claim 17 (depends on 16) The method of claim 16 wherein each said source in said array has a north pole directed toward the cervico-dorsal region of the body. ### Claim 18 (depends on 17) The method of claim 17 wherein said sources have a combined magnetic flux density from substantially 10,000 Gauss to substantially 75,000 Gauss. ### Claim 19 (depends on 18) The method of claim 18 wherein each said source is a ceramic permanent magnet. ### Claim 20 (depends on 18) The method of claim 18 wherein each said source is a neodymium permanent magnet. ### Claim 21 (depends on 12) The method of claim 12 wherein said sensation is of pain. ### Claim 22 (depends on 1) The method of claim 1 wherein said sensation is perceived to be originating in the lumbar-sacral region of the body. ### Claim 23 A method for reducing transmission in a human body of sensation along a course of a nerve from a body part to the brain, said course extending from said body part to the brain, said sensation originating in said body part, the method comprising the steps of: a) disposing at least one source of magnetic flux in close proximity to a point along said course remote from said body part between said body part and the brain; and b) allowing said source to remain so disposed for a period of time sufficient to reduce transmission of said sensation from said body part to the brain. ### Claim 24 A method for reducing transmission in a human body of sensation from a body part to the brain, said sensation originating and perceived to be originating in said body part, said body part being located at or below the lumbar-sacral region of the body, the method comprising the steps of: a) disposing at least one source of magnetic flux in close proximity to the lumbar-sacral region of the body; and b) allowing said source to remain so disposed for a period of time sufficient to reduce transmission of said sensation from said body part to the brain. ### Claim 25 (depends on 24) The method of claim 24 wherein there are multiple said sources having combined magnetic flux density from substantially 10,000 Gauss to substantially 75,000 Gauss. ### Claim 26 (depends on 25) The method of claim 25 wherein each said source has a north-south magnetic axis and a north pole and is disposed such that said magnetic axis is substantially perpendicular to the surface of the body in the lumbar-sacral region with the north pole directed toward the lumbar-sacral region. ### Claim 27 (depends on 25) The method of claim 25 wherein said sources are arranged into an array by a supporting web having a smoothly curved inner surface, each said source having a magnetic axis oriented substantially perpendicular to said inner surface, said array being disposed with said inner surface substantially parallel to the surface of the body in the lumbar-sacral region. ### Claim 28 A method for reducing transmission in a human body of sensation from a body part to the brain, said sensation originating and perceived to be originating in said body part, said body part being located in the upper extremities of the body, the method comprising the steps of: a) disposing at least one source of magnetic flux in close proximity to the cervico-dorsal region of the body;
