Abstract: 〔目的〕Trail making test(TMT)施行中における前頭葉の活動について,近赤外線分光法(near-infrared spectroscopy;NIRS)による脳内血液酸素動態を測定し検討した。〔対象〕地域在住の高齢者13名(平均年齢:72.2±5.8歳)であ る。〔方法〕TMT施行中の酸素化ヘモグロビン(HbO2)の変化について,NIRSを用いて測定した。〔結果〕TMT開始直後からHbO2の有意な上昇が認められ,開始7秒後にピークを迎えた後もHbO2の上昇はTMT終了時まで維持された。〔結語〕高齢者がTMTを施行する際には,前頭葉の活動が促進されることが明らかとなり,TMTの注意機能や前頭葉機能評価尺度としての妥当性が客観的データに基づき示唆された。 / [Purpose] We measured cerebral blood oxygen kinetics with near infrared spectroscopy (NIRS) and examined the activity of the frontal lobe in subjects performing the trail making test (TMT). [Subjects] The subjects were 13 community-dwelling elderly persons: average age, 72.2 ± 5.8 years. [Methods] We measured changes in hemoglobin (HbO2) oxygenation using NIRS while subjects performed TMT. [Results] A significant increase in HbO2 was found immediately after the start of TMT, and elevation of HbO2 was maintained until the end of TMT following a peak at 7 s after the start of TMT. [Conclusion] We clarified that performance of TMT by the elderly promotes the activity of the frontal lobe, suggesting the appropriateness of TMT attention and frontal lobe function assessment scales, and also that they are grounded on objective data.
