Cervical/neck collars are commonly used by patients who have had a surgical intervention of the cervical spine, to immobilise the neck. It is also used for the treatment of neck pain, caused by acute trauma or chronic pain. After a whiplash injury, the neck collar can be used for both immobilisation and to reduce pain, although the value of the collar over early active mobilisations is questioned as early mobilisations can give a greater improvement in cervical range of motion and in the reduction of pain following a whiplash injury.
