Objectives: Magnetic stimulation is known as one of the treatments of arthritis. Magnetic stimulation has been reported to change the molecular structure of water, resulting in an improvement of blood circulation at the affected part. The purpose of this study was to investigate the effects of magnetic therapeutic instrument; CellPower® (3-5 Hz, 800 G) in human with chronic arthralgia.
Methods: We recruited 18 volunteers of 20-65 years old with arthralgia. We examined the serial effects of CellPower® using physiological parameters (body temperature: BT, skin temperature of exposure part; ST, pulse rate: PR, blood pressure: BP) , Range of Motion test (ROM) and Visual Analog Score (VAS) score. Magnetic field exposure was done twice a day for 30min for 2w. We performed cross-over trial using real instrument and placebo for 2w each with washout period of over 4w between the two protocols.
Results: Concerning about physiological parameters, in protocol A, ST after the exposure at 2w was ignificantly increased compared with that of Ow. In protocol B, diastolic BP after the exposure at 2w was significantly decreased compared with that of Ow. In both protocol, PR after the exposure was significantly decreased compared with that of before the exposure. All alterations were within normal values. There were no significant alterations in BT and systolic BP during the exposure. Also, there was no significant changes of ROM during the study. Interestingly, changes of VAS score showed a significant decrease by magnetic field exposure of CellPower®. Our results indicated that CellPower® had no baneful effects on physiological parameters and might be useful for the treatment of chronic arthralgia in safety.
