Summary of a Study conducted at San-Ikukai Hospital, Tokyo Communications Hospital And Kouseikai Suzuki Hospital.
The study conducted was a 12 month, double-blind clinical test of magnetic mattress pads in 3 of Japan’s foremost hospitals. 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 total number of subjects in this double-blind clinical experiment was 431 (216 male, 215 female).
375 subjects were given the magnetic pads. 56 were given non-magnetic pads. None of the 431 subjects knew which pad they were sleeping on. Subjects selected for the experiment were those with complaints chiefly related to neck and shoulder pain, back and lower back pain and general back pain.
To determine the presence of any side effects, blood pressure, haemoglobin, number of erythrocytes and number of leucocytes were examined before and after the use of the mattress pads. Besides blood sedimentation, TP, COL, ALT, GOT, GPT, Na and K were also examined, as were functions of 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. The percentage of subjects who realised the effect of the magnetic mattress pad within 3 days:
- neck and shoulder pain: 46.9%
- back and lower back pain: 50%
- general back pain: (38.7%)
Out of 375 total subjects who slept on the magnetic mattress pads, 200 (53.3%) realised the effects within 3 days. Over 70% realised 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, motor 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 the kidney, liver, pancreas, blood pressure and circulatory system. No clinical symptoms were found to indicate any side effects whatsoever.
After the year-long study, the conclusion was reached that “The magnetised health mattress pad proved to be effective on neck and shoulder pain, back and lower back pain"
