Quick Answer
Cervical dystonia, also called spasmodic torticollis, is a painful neurological condition in which the neck muscles contract involuntarily, causing the head to twist or turn to one side or tilt uncontrollably forward or backward. The most common pattern is the chin pulling toward the shoulder. It is the most common form of focal dystonia, typically begins gradually after age 30, and affects women more than men. There is no cure, but botulinum toxin injections into the affected muscles improve symptoms in most people and are repeated every three to four months, alongside sensory tricks, physical therapy, stress management, and, in severe cases, surgery.
What is cervical dystonia?
Cervical dystonia, also called spasmodic torticollis, is a painful condition in which your neck muscles contract involuntarily, causing your head to twist or turn to one side. Cervical dystonia can also cause your head to uncontrollably tilt forward or backward.
It is a rare disorder that can occur at any age, but it most often occurs in middle-aged people — and women more than men. Symptoms generally begin gradually and then reach a point where they don't get substantially worse.
One reassuring detail is worth noting upfront: cervical dystonia is the most common form of focal dystonia — dystonia confined to one part of the body — and it is not contagious, not caused by anything you did wrong, and in most cases not preventable.
For scale: epidemiological studies estimate cervical dystonia affects roughly 5 per 100,000 people, and it is by far the most common dystonia manifestation — about 42% of all dystonia patients in the largest epidemiological studies have the cervical form. NINDS also notes that about 10% of people with cervical dystonia may have no symptoms for a period of time.
What does cervical dystonia feel like? Symptoms
The muscle contractions involved in cervical dystonia can cause your head to twist in a variety of directions:
Chin toward shoulder — the most common type of twisting in cervical dystonia
Ear toward shoulder — lateral tilt of the head
Chin straight up — backward extension of the neck
Chin straight down — forward flexion of the neck
Some people experience a combination of abnormal head postures. A jerking motion of the head also may occur.
Many people who have cervical dystonia also experience neck pain that can radiate into the shoulders. The disorder can also cause headaches. In some people, the pain from cervical dystonia can be exhausting and disabling.
Because the visible head postures overlap with simpler problems, it is worth stating clearly: persistent, involuntary neck twisting that you cannot control — especially with pain — is not an ordinary muscle strain. That pattern is what should prompt a neurological evaluation.
What causes cervical dystonia?
In most people with cervical dystonia, the cause is unknown. However, research has identified several contributing factors:
Unknown (idiopathic) — in most people with cervical dystonia, the cause is unknown
Family history — some people with cervical dystonia have a family history of the disorder
Gene mutations — researchers have found gene mutations associated with cervical dystonia
Injury — cervical dystonia is sometimes linked to head, neck or shoulder injuries
Who is at risk?
Risk factors for cervical dystonia include:
Age — while the disorder can occur in people of any age, it most commonly begins after age 30
Sex — women are more likely to develop cervical dystonia than men
Family history — if a close family member has cervical dystonia or some other type of dystonia, you are at higher risk of developing the disorder
Published studies place the prevalence at roughly 5 per 100,000 people overall, with U.S.-based estimates running from about 9 to 30 per 100,000 — and women are affected approximately twice as often as men.
What complications can it cause?
In some cases, the involuntary muscle contractions associated with cervical dystonia can spread to nearby areas of your body. The most common locations include the face, jaw, arms and trunk.
People who have cervical dystonia may also develop bone spurs that may reduce the amount of space in the spinal canal. This can cause tingling, numbness and weakness in the arms, hands, legs or feet.
The psychosocial impact is equally important and frequently underdiscussed. Severe cases may make you feel uncomfortable in social situations or even limit your ability to accomplish everyday tasks such as driving. Many people with cervical dystonia feel isolated and depressed.
How is cervical dystonia diagnosed?
While a physical examination alone can often confirm a diagnosis of cervical dystonia, your doctor might suggest blood tests or magnetic resonance imaging (MRI) to rule out any underlying conditions causing your signs and symptoms.
In practice, the diagnosis rests on recognizing the characteristic involuntary head posture and movement patterns during examination, and ruling out other causes. You might first discuss your symptoms with your family doctor, who may refer you to a neurologist — a doctor who specializes in disorders of the brain and nervous system — for further evaluation.
How is cervical dystonia treated?
There is no cure for cervical dystonia. In some people, signs and symptoms may disappear without treatment, but recurrence is common. Treatment focuses on relieving the signs and symptoms.
Botulinum toxin injections
Botulinum toxin, a paralyzing agent often used to smooth facial wrinkles, can be injected directly into the neck muscles affected by cervical dystonia. Examples of botulinum toxin drugs include Botox, Dysport, Xeomin and Myobloc.
Most people with cervical dystonia see an improvement with these injections, which usually must be repeated every three to four months.
To improve results or to help reduce the dosage and frequency of botulinum toxin injections, your doctor might also suggest oral medications that have a muscle-relaxing effect.
Therapies and self-care
Several non-invasive approaches can be layered on top of injections:
Sensory tricks — touching the opposite side of your face or the back of your head may cause spasms to stop temporarily; different tricks work for different people and they often lose effectiveness as the disease progresses
Heat packs and massage — can help relax your neck and shoulder muscles
Neck exercises — exercises that improve neck strength and flexibility may be helpful
Stress management — signs and symptoms tend to worsen when you're stressed, so learning stress management techniques is important
Surgery and other procedures
If less invasive treatments don't help, your doctor might suggest surgery:
Deep brain stimulation — a thin wire is guided into the brain through a small hole cut into the skull; the tip is placed in the portion of the brain that controls movement, and electrical pulses interrupt the nerve signals making your head twist
Cutting the nerves — another option is to surgically sever the nerves carrying the contraction signals to the affected muscles
Can cervical dystonia resolve on its own?
Partially. The disorder sometimes resolves without treatment, but sustained remissions are uncommon — and when spontaneous improvement does occur, recurrence is common. This is why ongoing follow-up matters even in people who improve without active treatment.
How to prepare for your appointment
Because appointments can be brief, plan ahead and write a list that includes: family medical history (information about the medical problems of your parents or siblings), all medications and dietary supplements you take, and questions you want to ask the doctor.
Your doctor may ask some of the following questions: When did your symptoms start? Have your symptoms worsened over time? Does anything seem to help relieve your symptoms? What medications do you take?
How to cope and find support
Severe cases of cervical dystonia may make you feel uncomfortable in social situations or even limit your abilities to accomplish everyday tasks such as driving. Many people with cervical dystonia feel isolated and depressed.
Remember that you're not alone. A number of organizations and support groups are dedicated to providing information and support for you and your family — whether you have the disorder or you have a friend or family member who does. Your doctor may be able to suggest support groups available in your area, or there are a number of good sites on the internet with information about local support groups.
Conclusion
Cervical dystonia (spasmodic torticollis) is a rare but recognizable neurological condition in which the neck muscles contract involuntarily, pulling the head into abnormal postures — most often chin toward the shoulder — accompanied by neck pain that can radiate into the shoulders and cause disabling headaches. It typically begins gradually after age 30, affects women more than men, and in most cases has no identifiable cause.
There is no cure, but the outlook is far from bleak: most people see meaningful improvement with botulinum toxin injections, which can be combined with oral muscle relaxants, sensory tricks, physical therapy, and stress management — with deep brain stimulation and nerve-cutting surgery reserved for the small number of cases where less invasive treatments fail. The social and emotional toll, including isolation and depression, is real and worth addressing alongside the physical symptoms.
If you notice persistent, involuntary neck twisting or tilting that you cannot control — especially with pain radiating into your shoulders — don’t write it off as a simple muscle strain. See a doctor for a proper evaluation, ask about a referral to a neurologist, and if cervical dystonia is confirmed, ask about botulinum toxin injections and a coordinated care plan. Help exists, and treatment works for most people.
Frequently Asked Questions
What is cervical dystonia?
Cervical dystonia, also called spasmodic torticollis, is a painful neurological condition in which the neck muscles contract involuntarily, causing the head to twist or turn to one side, or to uncontrollably tilt forward or backward. It is the most common form of focal dystonia.
What causes it?
In most people, the cause is unknown. Some people have a family history of the disorder, researchers have found gene mutations associated with it, and it is sometimes linked to head, neck or shoulder injuries.
Who is most likely to get it?
It can occur at any age but most commonly begins after age 30. Women are more likely to develop it than men — roughly twice as often — and having a close family member with cervical dystonia or another type of dystonia raises your risk.
What is the most common head posture?
The most common type of twisting is when the chin is pulled toward the shoulder. Other postures include ear toward shoulder, chin straight up, and chin straight down, and some people experience combinations with jerking head motions.
Is it curable?
There is no cure. The disorder sometimes resolves without treatment, but sustained remissions are uncommon and recurrence is common. Treatment focuses on relieving the signs and symptoms.
How is it treated?
Botulinum toxin injections into the affected neck muscles improve symptoms in most people and are usually repeated every three to four months. Oral muscle-relaxing medications, sensory tricks, heat, massage, neck exercises, and stress management help, and deep brain stimulation or nerve-cutting surgery may be used in severe cases.
How long do botulinum toxin injections last?
Improvement from injections usually must be repeated every three to four months.
Can the condition spread?
In some cases, the involuntary contractions can spread to the face, jaw, arms and trunk. People may also develop bone spurs that reduce space in the spinal canal, causing tingling, numbness and weakness in the limbs.
