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
