Cervical multifidus muscles arise from the superior articular processes of C4 – C7. They extend superomedially to insert on the lateral aspect and the tips of the spinous processes of C2 – C5 vertebrae. Thoracic multifidus originate from the transverse processes of the thoracic vertebrae.
One study conducted by Bogduk (1996) identified the pain referral patterns of cervical facet joints. This information was derived from 61 volunteers who underwent a zygopophyseal joint injection and facet joint denervation in a pain clinic in Japan. They developed this referral chart for clinical use…… (Bogduk, 1996, p. 81).
As shown in the diagrams below, the multifidi trigger points lie along each side of the spine and sacrum, within the paravertebral canals. The diagrams above also show the referred pain associated with the multifidi trigger points.Referral Multifidi Mid Cervical Image Diagram - Chart - diagrams and charts with labels.
