At one of our Roundtable meetings a couple of years
ago, a fellow brought what looked like a dremel tool,
basically a motor with a ball mounted on it. In the
ball were magnets with alternate polarities so that
when the motor spun the ball, the magnetic field would
rapidly change.
The idea being to hold it near your body (it was
inside a plastic cover so you could touch the skin) so
that the changing currents would induce potential in
the bones and body. To prove the strength of the
field, he had another device that was basically a hall
effect switch which turned on an LED everytime the
ball switched polarity.
He held the rotating ball against my back with the
detector near my stomach and it clearly showed the
rotating magnetic field as penetrating my body. He
did this on other people there and we were surprised
to see that the field was so strong.
I really liked the exceedingly simple redneck method
of just spinning a magnet as opposed to some complex
circuit.
This could be an interesting tie-in with the patent
for the magnetic beam as a product that could be
useful to people.
More on the microcurrents;

Ultrasound delivery systems use pulsed radio-frequency
waves (in the MHz range) to treat bone fractures.
These systems take advantage of the piezoelectric
nature of bones. When ultrasound is applied to the
fracture bone, the ultrasound is converted to an
electric current in the bone to promote healing by
small deflections within the bone. Such systems are
described in U.S. Pat. Nos. 5,003,965 and 5,186,162 to
Talish et al both incorporated herein by reference.
The stresses induced in the bone are of the order of
100 kilopascals (kPa). The ultrasound carrier
frequencies are about 1.5 MHz and higher. As the bone
deflects in response to the ultrasound, bone growth is
promoted. Clinical studies show that exposure of the
fracture site for 20 minutes per day to such an
ultrasonic stimulus will halve the time necessary to
ensure a fully healed fracture.
Pulsed electromagnetic field coil (PEMF) for healing;
http://164.195.100.11/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=20&f=G&l=50&co1=AND&d=pall&s1=mcleod&OS=mcleod&RS=mcleod
Known methods and apparatuses which have been used to
treat injuries using PEMF include the use of Helmholtz
and toroidal coils to deliver PEMF. These methods and
apparatuses have suffered from various deficiencies.
For example, Helmholtz coils suffer from field
inhomogeneity and field dropouts (e.g., the field
drops to zero near the center of the coil). Toroidal
coils are inefficient and have a relatively weak field
strength. Further, known methods of PEMF treatment
have problems associated with system complexity, large
size and weight, long, treatment times, weak PEMF
strength and low efficiencies in promoting healing.
Current devices and methods of PEMF treatment further
fail to provide adequate mobility during treatment.
Existing magnetic coil devices typically rely on
spatial separation of the opposing sides of the coils
to prevent detrimental interference of the magnetic
fields. To achieve spatial separation, typically, a
relatively thick and bulky core is implemented. A
thick or bulky core can make it difficult to wrap or
position the coil in certain treatment areas, for
example, a patient's fingers. Other drawbacks also
exist.
Electronic pain control;

An improved transcutaneous electrical nerve stimulator
(TENS) involving a microcurrent (typically 25 to 900
microamps) monophase D.C. carrier signal (typically
10,000 to 19,000 Hz, preferably 15,000 Hz) that is
modulated on and off in time (typically at 0.3 Hz up
to 10,000 Hz, preferably 9.125 Hz followed by 292 Hz)
and further inverted about every second by reversing
the polarity of the signal at the electrodes. Such a
device has been found to be useful in alleviating pain
very rapidly.
This invention relates to an improved transcutaneous
electrical nerve stimulation (TENS) apparatus for
symptomatic relief and management of chronic (long
term) intractable pain and adjunctive treatment in the
management of postsurgical traumatic acute pain. More
specifically, the invention relates to a TENS device
that operates in the electrical current range of about
25 microamps to less than 1 milliamp using a chopped
(e.g., 9.125 Hz or 292 Hz) carrier frequency (e.g.,
15,000 Hz) having typically a monophasic wave profile
which is preferably inverted (reversed polarity)
approximately every second.
For routine pain management the use of 9.125 Hz
followed by 292 Hz is particularly useful. The present
invention also provides a unique LED electrode that
produces electromagnetic radiation synchronously with
the electrical current therapy.
