The neck is made up of 7 vertebrae forming the cervical spine. It plays the mechanical role of supporting the head. Crossed by the spinal cord - the body’s sensory-motor command centre - it is a highly sensitive zone. The main neck problems are related to injury (sprain, torticollis) or degenerative conditions (arthritis).
Cervical collars immobilise the cervical spine, limiting flexion, extension and rotation movements. The degree of immobilisation varies depending on the rigidity of the collar.
They also play a proprioceptive role, reinforcing sensations from the cervical spine, as well as an analgesic role due to their thermal action combined with immobilisation.
