Population ‐Level Correction of Systematic Motion Artifacts in fMRI in Patients with Ischemic Stroke

CONCLUSIONSWe proposed a postprocessing pipeline for ischemic stroke fMRI data that combine the CompCor correction at first level with the modeling of motion effect at second‐level analysis by a parameter obtained from fMRI data. Our solution is applicable for any fMRI‐based stroke rehabilitation study since it does not require any MRI‐compatible motion capture system and is based on commonly used methods.
