Clinical Test of Magnetic Mattress PadsBy 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.
Symptom Cases Positive Results % No Results Results %
Neck and shoulder pain 66 47 71.2 19 28.8
Back and lower back pain 76 61 80.3 15 19.7
Back pain (general) 31 25 80.7 6 19.3
Lower limb pain 68 54 79.4 14 20.6
Insomnia 70 61 87.1 9 12.9
Fatigue 64 53 82.8 11 17.2
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%
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.
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."
