Brain Activity Measurement by fMRI and NIRS at the Rehabilitation Training

Abstract

Recently, the number of stroke patient has been increasing in many countries including Japan according to aging of population. Besides the number of physical therapist (PT) has not increased despite of the aging of society and the absence of PT is one of the social problem. Therefore an own forcing training is required on behalf of externally forcing training by PT. Biophilia institute made some devices for rehabilitation, which device called "Pata-Koro", and it is reported that the devices are valid for own forcing training. In this study the purpose is to measure brain activity by fMRI and NIRS at the rehabilitation training. First, we perform image processing MRI image and NIRS image at the rehabilitation training. Next, the correspondence relation of fMRI image and NIRS image is discussed and the feature of rehabilitation score of fMRI and NIRS. Since fMRI is ill-suited for fMRI inspection because we cannot bring the devices of rehabilitation at the inspection, and we decide the use of NIRS for measurement at rehabilitation. Final goal of this study is to analyze the time-dependent change of brain function by rehabilitation effect using NIRS.
