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).
ACTION PRINCIPLE:
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.
