1. An apparatus for limiting the movement of the head of a person, the head having a left half and a right half either or both of which are susceptible to changes in geometry over time, the apparatus comprising:

  • a link system including a plurality of links;

    a first plurality of constraints rigidly coupled to a first link of the link system and adapted to engage the left half of the head of the person; and

    a second plurality of constraints rigidly coupled to a second link of the link system and adapted to engage the right half of the head of the person;

    wherein the link system is configured to exert a force on the head of the person through the first plurality of constraints and the second plurality of constraints such that the head is generally fixed and is further configured to simultaneously adapt to changes in the geometry of the head such that the head remains generally fixed over a period of time.
