本研究では,家庭用機器として販売されているパルス性磁気発生装置:セルパワー®を用いて,慢性関節痛を訴えるヒトを対象に定期的磁場照射を実施し,生理学的指標の変化と効果を主観的･客観的評価指標を用いて検討した。対象は,慢性関節痛を訴える20～65歳の男女18名。同一関節痛部位に対して照射を1日2回(午前･午後),30分間,2週間施行した。同一被験者に磁場発生(-)機器(偽)と磁場発生(+)機器(真)を用いてクロスオーバー試験を行った。毎照射前後に腋窩体温,照射部位皮膚温度,脈拍数,血圧を測定した。開始時から4週間後まで1週間ごとに関節可動域(ROM)および痛みの指標(VAS)を計測した。一部のプロトコールでは,使用前後で照射部位の皮膚温度が軽度に上昇,拡張期血圧が有意に低下した。脈拍数は,全プロトコールにおいて使用後に有意に低下した。腋窩体温,ROM相対値に有意な急性･慢性変化はなかった。2週間の磁場照射によりVASの有意な低下がみられた。セルパワー®は成人の慢性関節痛に対し,生理学的指標に悪影響を及ぼすことなく使用できること,照射による鎮痛効果を有することが示された。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
