| Outline of Final Research Achievements |
In this study, we considered to develop and improve lower extremity rehabilitation system based on detected movement intentions by electroencephalogram.
In an early stage of this study, we detected user’s motor intention by using so-called event-related desynchronization phenomenon in electroencephalogram. In addition to this, we attempted to simultaneously use visual evoked potentials expressed by constant-period visual stimuli, which are commonly used in menu selection-type brain computer interfaces. The experimental results were shown that both event-related desynchronization and visual evoked potentials can be used simultaneously as feature values for interface. Furthermore, we also investigated a novel visual evoked potential based interface and a rehabilitation system without direct motor stimulation using a head-mounted display.

本研究では事故などで下肢運動麻痺となった患者さんに対するリハビリテーション手法として，脳波から運動意図を推定し，運動意図に応じて麻痺患部に運動刺激を与える装置と，これを実現するための関連技術の検討を行った．特に本研究では運動意図の有無によって生じる脳波と視覚刺激を行うことで生じる脳波を同時に利用できるかについての調査を行い，同時利用が可能であることを示唆する結果を得た．この結果を利用することで脳波からの状況判別をより柔軟に行える可能性があり，今後，脳波を利用したリハビリテーションシステムの制御に利用できると考えられる．
