Clinical Test of Magnetic
Mattress Pads
By Dr Kazuo Shimodaira
The mattress pads used in
this study were typical full-size pads containing 124 permanent ferrite magnets
with magnetic field strengths of 750-950 gauss each. The pads themselves were
made of two sheets of felt with the magnets sandwiched between them. The felt
sheets were then wrapped in a cloth cover. The total number of subjects of this
double-blind clinical experiment was 431 (216 male, 215 female). 375 subjects
were given the magnetic pads, 56 were given nonmagnetic pads. None of the 431
subjects knew which pad they were sleeping on. Subjects selected for the
experiment were those with chief complaints related to: neck and shoulder pain,
back and lower back pain, back pain (general), lower limb pain, insomnia,
fatigue.
To determine the presence of
any side effects, blood pressure, hemoglobin, number of erythrocytes, and
number of leukocytes were examined before and after the use of the mattress
pads. Besides blood sedimentation, TP, COL, ALP, GOY, GPT, NA, and K were also
examined, as were functions of the kidneys, liver, pancreas, and the entire
circulatory system.

Out of 375 total subjects
with symptoms, 301 (80.27%) reported positive results. 74 cases (19.73%)
reported no results.
Time of Response
The percentage of subjects who realized the effect of
the magnetic mattresspad within 3 days:
Neck and shoulder pain 46.9%
Back and lower back pain 50.0%
Back pain
38.7%
Lower limb pain
54.4%
Insomnia
64.3%
Fatigue
57.8%
Out of 375 total subjects who
slept on the magnetic mattresspads, 200 (53.3%) realized the effects within 3
days. Over 70% realized the effects within 5 days.
Testing for side effects was
conducted at the conclusion of the experiment. Symptoms such as tinnitus,
headache, hearing problems, visual disturbances, vertigo, palpitation,
perceptive abnormality, motorial disturbance, fever, digestive disturbance,
cutaneous symptoms, and other clinical symptoms to suggest any side effects
were found to be totally absent. Extensive testing was also done before and
after the experiment to check functions of kidney, liver, pancreas, blood
pressure, and the circulatory system. No clinical symptoms were found to
indicate any side effects whatsoever.
Conclusion
Dr. Shimodaira's conclusions of this year long study
conducted in three of Japan's foremost hospitals: "The magnetized health
mattresspad is proven to be effective on neck and shoulder pain, back and lower
back pain, lower limb pain, insomnia, and fatigue, and to have no side
effects."
