I have been asked in court from the insurance companies attorney " Since the patient had a head restraint, wouldn't that minimize injuries?" Well, maybe, however here is a study that shows even with head restraints, necks get injured. This is why so many factors need to be evaluated and asked during your exam with your patient. What may be more important, is asking your patient what position the head restraint was in during the impact. Here is a abstract of a study that shows neck ligaments get damaged even with head restraints.
