If you are allowed to remove the collar to wash your child’s neck, ensure their head and neck do not move.

Plain film radiography [ 7, 8], cineradiography [ 9, 10], videofluoroscopy [ 11], computerised tomography [ 12], magnetic resonance imaging [ 13], video and electromyography [ 14], digital inclinometry [ 15], stereophotogrammetry [ 16], electrogoniometry [ 17] and motion analysis systems [ 1– 3, 18, 19] have been used to measure cervical spine motion. The front piece of the collar will sit under your chin and upon your chest, the back panel will sit at the base of your skull and extend to your shoulders.This will depend on how quickly the injury heals, which will normally be checked with an X-ray or an assessment in hospital. You will also need to be able to sit comfortably in the collar, get yourself in and out of bed, walk short distances and be able to walk up and down a flight of stairs (if you have them at home).

The Aspen Vista collar was inferior to all the other collars at restricting lateral bending movements while the Aspen collar appeared to be the most effective at restricting movement in this plane. Your doctor will tell you whether your child needs to keep their collar on all the time or if it can be removed. The cervical spine, however, does not move as one unit; paradoxical motion, the phenomenon of "snaking," occurs.The Vista (Aspen) hard collar is a 2-piece collar, with a separate front and back, which fasten together with Velcro. For ultimate comfort, all of the collar's contact surfaces are cushioned with cotton-lined, breathable foam padding. You will be advised to wean yourself from the collar gradually to prevent sudden strain on your neck and also to help to strengthen your neck muscles slowly to minimise discomfort.
