A splenius capitis contracture is the persistent tightening or shortening of the splenius capitis muscle—the strap‑like muscle that runs from the upper spine to the back of your skull. When the muscle stays in spasm it loses flexibility, pulls the head to one side, and causes neck pain, stiffness, and poor posture.
Basic anatomy of the splenius capitis muscle
Structure & location
The splenius capitis is a broad, flat muscle that lies deep to the trapezius on the back of the neck and upper back. It spans from the mid‑spine (C‑7 to T‑3) up to the base of the skull. Kenhub
Origin (where it starts)
-
Lower half of the nuchal ligament
-
Spinous processes of vertebrae C‑7 to T‑3/T‑4 Kenhub
Insertion (where it ends)
-
Mastoid process of the temporal bone (just behind your ear)

key functions
-
Extends the head (looks up).
-
Rotates the head toward the same side.
-
Bends (laterally flexes) the neck to the same side.
-
Helps maintain upright head posture.
-
Assists in gentle head retraction (tucking the chin).
-
Works with neighboring muscles to stabilize the cervical spine during chewing and heavy lifting. KenhubThe Wellness Digest
A contracture happens when the muscle fibers and surrounding fascia stay stuck in a shortened state for weeks or months. Scar‑like changes develop, the muscle becomes less elastic, local nerves get irritated, and normal neck movements—especially turning the head—become painful. The problem may appear on its own, after injury, or as part of broader conditions like cervical dystonia (spasmodic torticollis). Samarpan Physiotherapy ClinicJNNP
Types of contracture
-
Acute protective spasm – short‑term tightening after a strain.
-
Chronic myofascial contracture – long‑standing trigger‑point knots that shorten the muscle belly.
-
Post‑traumatic fibrotic contracture – scar tissue after whiplash or surgery.
-
Neurogenic contracture – driven by nerve disorders such as cervical dystonia.
-
Congenital muscular torticollis – rare birth‑related shortening of one neck muscle group that may include the splenius capitis.

Practical ways to prevent contracture
-
Keep your monitor at eye level to avoid chin‑poking.
-
Take 30‑second neck‑stretch breaks every 30 minutes.
-
Sleep on one medium‑height pillow that supports the natural curve.
-
Strengthen deep‑neck flexors and shoulder blade muscles twice a week.
-
Lift loads close to your body—no “one‑handed suitcase” carry.
-
Wear seat belts and adjust headrests to head height.
-
Warm‑up and cool‑down before and after sports.
-
Stay hydrated—muscles cramp more when dehydrated.
-
Manage stress with breathing or meditation to reduce tension holding.
-
Get regular vitamin‑D‑rich sun exposure or supplements as advised.
When should you see a doctor?
-
Sudden neck pain after an accident or fall
-
Ongoing pain or stiffness that lasts more than two weeks despite self‑care
-
Headaches or dizziness linked to neck movement
-
Numbness, tingling, or weakness in the arm or hand

Early medical review prevents chronic disability and helps you access imaging or injections quickly.
frequently asked questions (FAQs)
-
Is splenius capitis contracture the same as torticollis?
– It can be one cause of torticollis, but torticollis also involves other muscles. -
Can I treat it at home?
– Mild cases often respond to heat, gentle stretching, and posture fixes within 7–14 days. -
How long does recovery take?
– Acute cases may clear in weeks; chronic fibrotic contractures can take months. -
Will it come back?
– Yes, if posture errors or stress triggers persist. Prevention exercises are key. -
Does sleeping without a pillow help?
– Sometimes, but most people do better with a single supportive pillow. -
Are chiropractic adjustments safe?
– When done by a qualified practitioner on screened patients, they may relieve stiffness, but avoid rapid neck thrusts if you have arthritis or vascular risks. -
Is botulinum toxin painful?
– Injections are quick; discomfort is brief and similar to a bee sting. -
Will I need surgery?
– Only if conservative and injectable treatments fail and your quality of life is severely limited. -
Can anxiety really tighten my neck?
– Yes. Stress increases baseline muscle tone and can trigger or maintain contractures. -
Does magnesium help?
– Low magnesium can worsen cramps; supplements may help if your levels are low. -
What kind of doctor should I see?
– Start with a primary‑care physician or physiatrist; severe cases may need a neurologist or orthopedic spine surgeon. -
Are imaging tests always necessary?
– Not for every strain, but MRI or ultrasound is recommended when pain persists beyond six weeks or red‑flag signs appear. -
Can children develop this problem?
– It is rare but possible, especially after trauma or viral myositis. -
Is exercise bike or running okay?
– Yes, cardiovascular exercise is good, but keep your head in neutral and stretch afterward. -
Will insurance cover Botox or surgery?
– Most plans cover injections or surgery for documented cervical dystonia or contracture that fails therapy; check pre‑authorization rules.
A splenius capitis contracture is a common yet often overlooked reason for nagging neck pain and limited head turning. Good posture, timely stretching, and targeted physiotherapy solve most cases. Evidence‑based drug options, including botulinum toxin injections, provide added relief for stubborn spasms. Surgery is a last‑line choice but offers hope when all else fails. By understanding its anatomy, causes, and treatments, you can take practical steps to prevent, spot, and beat this painful neck problem.
