All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An apparatus for restricting movement of a patient’s head, the apparatus comprising: a frame; and a plurality of constraints engaged with the frame to constrain the patient’s head relative to the frame, wherein the plurality of constraints includes a first constraint including an axis oriented generally radial to the patient’s head, wherein the first constraint permits exactly five degrees of motion of the patient’s head relative to the frame including a first degree of motion generally permitting motion transverse to the axis of the first constraint and a second degree of motion of the five degrees of motion generally permitting a linear motion parallel to the axis of the first constraint.
2. The apparatus of claim 1, wherein the plurality of constraints exactly constrain the patient’s head relative to the frame.
3. The apparatus of claim 1, further comprising: a support structure that supports the frame, the support structure including a vest that is configured to be worn by the patient.
4. The apparatus of claim 1, further comprising:
a base member movably coupled to the frame to permit motion generally parallel to the axis of the first constraint; and
a head constraint member configured to engage the head, the head constraint member being moveably coupled to the base member to permit motion generally transverse to the axis of the first constraint.
