  1. *Data represent means (SD).
  2. †Time Post Injury = number of months between the last LBI and testing.
  3. ‡VAS = visual analog pain scale (0–100) at time of injury (higher score means greater amount of pain).
  4. §RMQ = Roland Morris Disability Questionnaire (0–24) at time of injury (higher score means greater level of disability).
  5. #Subjects were not re-tested during the follow-up period.
