 note = {今回我々は，隣に座る第三者の下肢映像を治療者（セラピスト）の一人称イメージ課題と想定し，セラピストの隣で自分の足を見つめつつ模倣運動を行う患者様，セラピストの隣で鏡に映る映像の模倣運動を行う患者様として脳活動の相違を fMRI にて比較した．あらかじめ準備した動画は，被験者自身の「一人称イメージ課題」映像と被験者自身の「三人称イメージ課題」映像および第三者の「一人称イメージ課題」映像である．結果，被験者自身の「三人称イメージ課題」は，被験者自身の「一人称イメージ課題」と比較して，左吻側前帯状皮質と左角回近傍部が賦活した．我々の先行研究では，第三者の「三人称イメージ課題」で右角回の賦活を示した．今回の結果は，先行研究と合わせて，脳梗塞として非常に多い中大脳動脈領域の脳活性化に，セラピストの立ち位置や患者様の目線を変えることで選択的に脳の部位を刺激する可能性があることを示している．, When performing rehabilitation for patients using motor imagery, there are two main modes: firstperson perspective imagery (1PPI: Kinesthetic motor imagery) and third-person perspective imagery (3PPI: Visual motor imagery). The purpose of this study is to determine the cortical representations in one's own 1PPI and 3PPI during motor imagery when engaging in toe movements in healthy people. Fifteen healthy subjects with right-dominant legs participated in the study after signing consent forms. An fMRI scan of 1.5T was used to map cortical representations associated with motor tasks of the right toes. In these tasks, subjects watched video clips depicting one's own 1PPI or 3PPI involving toe movements and were required to imitate the same actions. This time, the patients assumed that the lower limb image of the therapist sitting next to them us was "someone else's 1PPI task". Then, we prepared video clips of the patient's own 1PPI and 3PPI. Furthermore, using someone else's 1PPI imitation movement as a medium, we had patients imitate movements while looking at their own feet next to the therapist and then had patients who imitate the images reflected in the mirror next to the therapist. As a result, the patient's own 3PPI task, when compared with their own 1PPI task, showed an increased activation in the left angular gyrus and left rostral anterior cingulate cortex. In our previous study, someone else's 3PPI task showed an increased activation in the right angular gyrus. The results of this study, together with previous studies, show that it is possible to selectively activate brain regions, such as the middle cerebral artery region, which is very common in cerebral infarction, by changing the therapist's standing position and the patient's line of sight.},
