Complete Injury - Spinal Cord Injury Classified as Complete

Definition: To express how much sensory and motor function is lost after a spinal cord injury, one classification doctors use is:

• complete or
• incomplete.

This classification is based on how much of the width of the spinal cord has been affected by the injury.

Classifying SCI as complete or incomplete is done in addition to utilizing the ASIA Impairment Scale.

In a complete spinal cord injury none of the nerve cells in the spinal cord are functioning below the level of the injury, or lesion. In a complete spinal cord injury, all sensory and motor function below the level of the injury is lost.

According to the American Spinal Injury Assocation, the injury is complete if a patient shows no sacral sparing, i.e. the patient has no:

• voluntary anal contraction
• sensation in the anus
• sensation at the lowest 2 levels (S4 and S5) of the sacrum area
