Magnetic pain relief device by Jule Klotter, Townsend
Letter for Doctors and Patients, Jan. 2005

Scientists at Lawson Health Research Institute
(London, Ontario) have invented a small device that
uses a specific, pulsed, extremely low frequency (ELF)
magnetic field to reduce pain perception. They began
their research in 1995, by placing snails on a hot
surface (40 degrees C/ 100 degrees F). Snails prefer
cool surfaces and consistently reacted about five
seconds after contact with the heat. The researchers
then gave the snails morphine before placing them on
the hot surface. With the pain killer, it took the
creatures about 15 seconds to react. Next the
researchers exposed the snails to specific magnetic
fields and found one that produced the same delayed
reaction as the morphine.

Having identified a pain-reducing magnetic impulse,
the scientists moved on to humans. The Lawson
researchers developed a headset to deliver ELF
impulses and began testing the device on patients with
either fibromyalgia or with rheumatoid arthritis.
Patients wore the headsets for 40 minutes, at least
twice a day, for one week. The scientists found "a
significant reduction of pain in fibromyalgia and a
very significant reduction of pain in arthritis
patients." Alex Thomas, a bioelectromagnetics
scientist with Lawson, says that it may take ten years
before the device reaches the marketplace because of
scientific controls. The magnetic field produced by
this device is weaker than the field produced by an
electric hair dryer. The device has no known side
effects.
