The C4 Vario alleviates pain and contraction by immobilising the cervical spine, which restricts the movements responsible for inflammatory phenomena.

The C4 Vario helps with the static support of the head, reducing mechanical forces by compressing the cervical spine by means of an anterior lateral shell(with chin and sternal support) and a posterior shell (with occipital and upper dorsal support).

The increase in local heat, generated by wearing the C4 Vario, completes this analgesic role by affording improved muscle relaxation
