    Abstract:
    In order to reveal the precise degree of injury in the pyramidal tract after stroke, we studied 35 patients with motor deficit associated with cerebrovascular disease of the internal capsule using the T2-weighted coronal image along the 'pyramidal line'. According to the severity of the motor deficit, the patients were divided into three groups. The Wallerian index was calculated as: (area of Wallerian degeneration in the pons divided by area of the ipsilateral half of the pons) x 100. There were significant differences between the three groups. It is concluded that the area of Wallerian degeneration is related to the severity of motor deficit.
