A study of stroke lesions related to central post–stroke pain

Objective: We previously reported that the specific lesions in the thalamus, putamen, or brain stem could develop central poststroke pain (CPSP) in the retrospective MRI study. However, these findings can reflect only frequent locations of stroke. Therefore, in this study, we prospectively investigated detailed key structures to develop CPSP using voxel–based lesion map and odds ratio (OR) map comparing to patients without pain or with mild pain.
