Cervical dystonia, also known as spasmodic torticollis, is a neurologic movement disorder in which neck muscles contract involuntarily. These contractions can cause abnormal head posture, neck twisting, muscle tightness, and significant discomfort.
Botulinum toxin injections are the first-line treatment for cervical dystonia and are widely used by neurologists to reduce muscle overactivity. By temporarily weakening the overactive muscles, the treatment helps reduce abnormal movements, relieve pain, and improve daily function.
During treatment, specific neck muscles responsible for the abnormal movements are carefully identified and injected. The procedure is performed in the office and typically takes only a few minutes.
Results usually begin within 3–7 days, with improvement continuing over the following weeks. The effects typically last about 3–4 months, after which repeat treatment can maintain symptom relief.
Because cervical dystonia involves complex muscle patterns, treatment planning is individualized to each patient to target the muscles contributing most to the abnormal posture or pain.
Common Symptoms of Cervical Dystonia
Neck twisting or pulling
Head tilting or rotation
Neck muscle spasms
Chronic neck pain
Shoulder tightness
Tremor or shaking of the head
Treatment Areas
Botulinum toxin injections may be placed in muscles such as:
Sternocleidomastoid
Trapezius
Splenius capitis
Levator scapulae
Other involved cervical muscles
Duration
Appointment time: ~15–20 minutes
Onset of improvement: 3–7 days
Duration of effect: ~3–4 months
