The cervical multifidus connects articular pillars to spinous processes above, providing segmental control of cervical motion. It plays an analogous proprioceptive and stabilising role at the cervical level as lumbar multifidus does at the lumbar level.
| Origin | Articular pillars of C4-C7 |
|---|---|
| Insertion | Spinous processes of C2-C5 spanning 2-4 levels |
| Nerve Supply | Dorsal rami of cervical spinal nerves (C3-C7) |
| Blood Supply | Vertebral artery branches |
| Actions | Extension of the cervical spine; Contralateral rotation and ipsilateral lateral flexion; Segmental cervical stabilisation |

Cervical multifidus atrophy following whiplash is detectable by MRI and correlates with chronic neck pain. Its selective atrophy at the injury level is targeted by motor control rehabilitation.
Not directly palpable. Assessed by deep paraspinal EMG or MRI fat fraction.
Selective cervical multifidus fat infiltration at injury level correlating with pain chronicity, targeted by motor control rehabilitation.
