    Who knows. I wasn't involved in writing the protocols.

    I'm guessing that they take the presence of a helmet as a proxy for likelihood of injury in the event of a head injury. Maybe it's just a data point in their diagnosis. Maybe there's a differentiation in examination based on the presence of a helmet.

    Versus actually having accelerometers.

    And maybe lasers.

    In fact, definitely lasers.

    If there is, then all hope is lost, since even people who are supposed to be scientists have been fooled by the propaganda. Unless there's brain science I don't know about which points to very different treatment protocols based on the small statistical differences between helmet and no-helmet, i.e. helmet users tend to suffer slightly smaller linear accelerations, but no-helmet users tend to suffer smaller angular accelerations.
