| Outline of Final Research Achievements |
Motor skills training promote motor functional recovery and enhance synaptic plasticity after stroke. This study was focused on the effects of motor skills training on the expression of AMPA receptors subunits, MAP2, BDNF, and GAP43 mRNA following intracerebral hemorrhage (ICH) in rats. The mRNA expression of AMPA receptor subunits, GluR1, GluR2, GluR3 and GluR4, MAP2, BDNF, and GAP43 in bilateral sensorimotor cortex was analyzed using real-time PCR at 29 days after ICH. Our results suggest that sensorimotor functional recovery following motor skills training after ICH is promoted by dendritic growth and AMPA receptors in the ipsilesional sensorimotor cortex.

脳卒中リハビリテーションにおいて，運動療法は運動麻痺を改善させることができ，臨床現場では，様々な運動療法が展開されている．しかし，科学的根拠に基づいた運動療法が提供されているとは言い難く，それぞれの運動療法の効果を早急に追究する必要がある．本研究では，脳卒中後のスキル学習が脳機能を改善させ，機能回復を促進させる有効な運動療法であることを示した．本研究は，脳卒中後の運動療法としてスキル学習の有効性を示した研究資料として重要な意義を持つ．
