Corticospinal Tract after Spinal Cord Injury (review)

Spinal cord injury causes motor dysfunction below the level of damage plane,that due to the interruption of descending tracts passing movement instruction from the brain to the spinal cord.The main tract is the corticospinal tract which dominate the extremity motor function.The regeneration of the corticospinal tract or functional remodeling after spinal cord injury is anatomical pathology basis of promoting recovery of extremity motor function.This article discussed the anatomical knowledge of the corticospinal tract and previous classic methods of promoting corticospinal tract axon regeneration and repair and the latest research progress,in order to help the clinical treatment.
