| Outline of Final Research Achievements |
We evaluated whether peripheral magnetic stimulation below the motor threshold has the same effect on reducing spasticity as transcutaneous electrical nerve stimulation, electromyographically. In addition, we developed a small device to reduce spasticity using peripheral magnetic stimulation. The device generated a magnetic field by spinning magnet. Although the stimulation intensity of this device was below the sensory threshold, the electromyographic effects were equivalent to those of transcutaneous electrical nerve stimulation and conventional peripheral magnetic stimulation in healthy subjects and patients with spasticity. Thus, we succeeded in developing a new device for reducing spasticity using peripheral magnetic stimulation.

痙縮は上位運動ニューロン症候群による症候の1つでありその有病率も高く，日常生活活動の障害となる．痙縮に対しては経皮的電気刺激療法がエビデンスのある治療法として知られるが，電極貼付などの手間があるため日常臨床での使いづらさがあった．われわれは末梢磁気刺激を用いた新しい痙縮軽減機器の開発に成功した．この機器は小型で四肢に容易に装着可能であり，使用も簡便である．今後，痙縮の新しい治療法となる可能性がある．
