The brain functional maintenance improvement device which does from brain functional maintenance improvement effectively. The brain functional maintenance improvement device (10), reads out acknowledgment topic from the topic information section (16), in order to convey acknowledgment topic the shaking type kinematic device (12) which gives transitive shaking stimulus to the user and, vis-a-vis the data housing section (14) and the user which at least house one acknowledgment topic and the data housing section while giving transitive shaking stimulus to the user, has with the control section (18) which conveys acknowledgment topic to the user via the topic information section (16). As for the control section (10), while bringing the motion effect to the user with transitive shaking stimulus, you make answer to acknowledgment topic in the user.< Selective figure >Figure 1脳機能の維持改善をより効果的に行う脳機能維持改善装置。脳機能維持改善装置(10)は、ユーザに他動的揺動刺激を与える揺動型運動装置(12)と、少なくとも1つの認知課題を格納したデータ格納部(14)と、ユーザに対し認知課題を伝えるための課題報知部(16)と、データ格納部から認知課題を読み出し、ユーザに他動的揺動刺激を与える間に課題報知部(16)を通じてユーザに認知課題を伝える制御部(18)とを備える。制御部(10)は、他動的揺動刺激によってユーザに運動効果をもたらす間に、ユーザに認知課題に答えさせる。【選択図】図1
