Answer

Prognosis can be predicted with the American Spinal Injury Association (ASIA) impairment scale (see Physical Examination ), as follows:

  • ASIA A: 90% of patients remain incapable of functional ambulation (reciprocal gait of 200 feet or more)

  • ASIA B: 72% of patients are unable to attain functional ambulation

  • ASIA C/D: 13% are unable to attain functional ambulation 1 year after injury
