1. The latest model of CAD trauma describes a temporary change in cervical spine alignment and is characterized by:
- A straightened cervical curve.
- A reversed cervical curve.
- An s-shaped curve.
- A c-shaped curve.
2. Critical to how injury occurs at this point is a vertical shift in the lower cervical spine of the vertebral body's:
- Central locus of control.
- Instantaneous axis of rotation (IAR).
- Bending moment.
- Internal pressure.
3. Of the various generators of pain in people suffering from the effects of late (i.e., chronic) whiplash, which is most prominent?
- The zygapophyseal joint.
- The joints of Luschka.
- The intervertebral disc.
- The muscles and fascia.
4. During the temporary spinal configuration change mentioned in question #1, what are the effects on the motion segments themselves?
- The upper segments extend while the lower segments hyperflex.
- Both upper and lower segments hyperextend.
- Both remain within the normal intervertebral ranges of motion.
- The upper segments flex while the lower segments hyperextend.
5. What does the SCL-90R stand for?
- Serial counting logic 90, refereed.
- Subset of clinical logic 90, revised.
- System checklist 90, revised.
- Seven-count learning 90, remedial.
6. What did Dr. Nick Bogduk and cohorts discover about the SCL-90R profiles in late whiplash patients vs. control subjects asked to deliberately attempt to fake a profile?
- There were no significant differences between the scores of people with late whiplash and controls.
- Control subjects could not successfully fake the SCL-90R profiles of the late whiplash patient.
- Late whiplash patients tend to overrate their problems with mathematics.
- Control subjects could success fully fake a late whiplash profile.
7. Of the following simple disability questionnaires, which is useful in CAD patients with primary complaints in the neck?
- Vernon and Mior's NDI.
- The Roland-Morris questionnaire.
- The Revised Oswestry questionnaire.
- None of these lend themselves to primary neck disorders.
8. Of these questionnaires, which is the most sensitive to temporal change?
- Vernon and Mior's NDI.
- The Roland-Morris questionnaire.
- The Revised Oswestry questionnaire.
- None of them are sensitive to changes in disability over time.
9. Which statement is most correct regarding the healing time of CAD injuries?
- Less than half will have recovered by 12 weeks postinjury.
- About 75% will have recovered by 12 weeks postinjury.
- Nearly all will have recovered by 12 weeks postinjury.
- None of these statements are even remotely correct.
10. The term "backset" refers to:
- The degree of extension of the head/neck during rear impact.
- The rearward motion of the head (a.k.a., "head lag") as it approaches the head restraint.
- The horizontal distance between the back of the head and the front of the head restraint before impact.
- The relative positions of the occupant's torso and the car's seat back.

How Do You Stack up?
- If you scored 9-10: You're an expert. We need more like you.
- If you scored 7-8: You're still above average. You're well read (or taught).
- If you scored 5-6: Average. And you call yourself an expert? Probably undeserved self-praise. You need to brush up.
- If you scored 3-4: Poor. You're not even a good guesser.
- Chance alone nearly guarantees you a score of 2-3! If you're treating these people, you definitely need to get current.
