SEMISPINALIS CERVICIS
• Origin
Transverse processes of T1-T6 vertebrae.
• Insertion
Spinous processes of C2-C5 vertebrae.
• Agonist(s)
- Splenius cervicis,
- Longissimus cervicis,
- Spinalis cervicis (for cervical spine extension).
• Antagonist(s)
- Sternocleidomastoid (for cervical flexion),
- Anterior scalene,
- Longus colli.
• Function
- Extends the cervical spine (neck),
- Assists in lateral flexion and rotation of the cervical spine,
- Stabilizes the cervical vertebrae during head movements.
TRIGGER POINT(S)
• Location
Trigger points are generally located along the mid-cervical region near the spinous processes, particularly between C2 and C5.
Due to its depth, these points are best accessed by palpating close to the spine.
• Pain Referral Pattern
Pain from trigger points in the semispinalis cervicis can refer up the back of the neck to the base of the skull, sometimes radiating into the head, causing tension headaches.
Pain may also be felt in the upper neck and occasionally radiate toward the shoulder blade area.
Pain Pattern
• Potential Causes
• Poor posture, particularly forward head posture
• Repetitive or sustained activities that involve looking down, such as computer or phone use
• Tension or stress causing muscle tightness
• Whiplash or sudden neck trauma
• Prolonged static positioning, such as driving or reading
• Prevention Tips
• Maintain proper posture to prevent excessive neck strain
• Take regular breaks during activities that require looking down
• Strengthen and stretch the neck muscles to support spinal alignment
• Use ergonomically designed furniture and devices to support neck posture
• Practice relaxation techniques to relieve tension in the neck.
