The thoracic region of the spinal column is made up of 12 segments referred to as T1 - T12. These changes translate into loss of muscle function, sensation, or autonomic function in parts of the body served by the spine below the level of the lesion. Complete Spinal Cord Injury: A complete injury means there is no function below the level of the injury – no sensation and no voluntary movement. Incomplete Spinal Cord Injury: An incomplete injury means there is some function below the primary level of injury. The following flow chart demonstrates the Spinal Cord Injury Subgroups methodology in approaching the problem of understanding the microenvironment of the lesion and how we would apply our scaffolding in order to achieve axonal regrowth.
