Neck movement support device, system and methods

A neck movement support device comprising:

• a stationary member;
• a movable member mounted to the stationary member at a first pivot point, the movable member being rotatable relative to the stationary member about the first pivot point, the first pivot point defining an anteroposterior neck movement axis;
• a handle connected to the movable member by a pair of four-bar linkages so as to approximate rotation about a second pivot point defining a mediolateral neck movement axis perpendicular to and intersecting the anteroposterior neck movement axis;
• and
• a head harness connected to the handle at a third pivot point, the head harness being rotatable relative to the handle about the third pivot point, the third pivot point defining a craniocaudal neck movement axis perpendicular to both the anteroposterior and mediolateral neck movement axes and sharing a mutual intersection therewith;
• wherein, with the stationary member positioned adjacent a treatment table and configured to hold a supine user, in which a head of the user is configured to be secured in the head harness that is configured to constrain the head to move or remain stationary along with the head harness about the anteroposterior, mediolateral and craniocaudal neck movement axes defined by the device, with the mutual intersection being located at cervical vertebra C7 of the user.
