Topic: hand grip movements

In order to assess the recovery of neural activity after stroke, it is necessary to select tasks that can be performed in the early stages of recovery. Since hand flexion is the first functional recovery that can be observed, it is a promising task to evaluate the recovery process. fMRI has reported that the amplitude of neural activity varies with the intensity of movement, but the correlation between movement and neural activity itself has not been reported in functional near-infrared spectroscopy (fNIRS). To investigate this, the present study performed simultaneous fMRI and fNIRS measureme
