 Cervical dystonia, also called spasmodic torticollis, is a type of neurological disorder characterized by spastic muscles in the neck that is largely underdiagnosed despite its progression to disability during midlife. Cervical dystonia occurs in at least 0.390 of the United States population in 2007 390 per 100,000. Symptoms commonly include stiffness, pain, headaches, difficulty swallowing, fatigue, and difficulty walking. The current standard treatment is intramuscular botulinum toxin injection every 90 days. The effect of the botulinum toxin increases gradually, and then it decreases until there is little to no effect at 90 days post-injection. The purpose of the proposed research is to determine if Osteopathic manipulative medicine OMM used in combination with the standard treatment of botulinum toxin intramuscular injections improves motor function and quality of life amongst people with cervical dystonia.
