逆転プリズムを用いたミラーセラピー時の脳活動の比較

抄録

Mirror therapy using mirrors has been used to restore upper limb function in stroke victims with hemiplegia. We used brain measurements to confirm whether the inverted prism can produce brain activity similar to that of the conventional mirror therapy technique. The results showed that both inverted prism and mirror therapy tended to enhance the inhibition of μ-rhythms. We also found that the ERD of the unaffected hemisphere was reduced in the low beta frequency band, suggesting that the inverted prism may induce brain activity similar to that of mirror therapy.
