Brief summary
BTX has been used since the 1980s in support of the research mission of NINDS. Initial studies were focused on expanding the applicability of BTX treatment to movement disorders and exploring new indications. We evaluated the efficacy of an alternative serotype, type F. Under other protocols, we continue to study the physiology of movement disorders and BTX response. The application of BTX therapy to movement disorders requires an understanding of BTX preparation and handling. The treatment must be tailored to the disorder under treatment and to its expression in the individual patient. Users must know the specific techniques of injection, including the use of EMG and ultrasound guidance. This protocol allows us to train physicians in all aspects of the use of BTX. It also provides us with a cohort of patients, receiving a standard method of treatment and with a stable response to BTX injection, for participation in other protocols on movement disorders and on the responses to BTX injection.
Detailed description
The efficacy of botulinum toxin (BTX) has now been demonstrated for a variety of diseases associated with involuntary muscles spasms or movement. The application of botulinum toxin therapy to movement disorders requires treatment tailored to the individual patient and specific techniques of injection. This protocol 1) allows us to follow the natural history of subjects with movement disorders who receive standard botox injections for treatment of movement disorders and 2) allows us to provide botulinum toxin injections for patients participating in other NIH studies.

Inclusion criteria
* INCLUSION CRITERIA: 1. Patients 2 years and older, will be eligible for participation if they have a disorder that, in the judgment of the treating physician, might be amenable to treatment with BTX. 2. Applicable disorders include but are not limited to dystonia, hemifacial spasm, blepharospasm, tremor, spasmodic dysphonia, tics, vocal fold tremor, oral lingual dyskinesia, tardive dyskinesia, spasticity, and spasmodic dysphonia.
Exclusion criteria
1. Women who are planning on becoming pregnant, are pregnant or breastfeeding, for the duration of the condition. 2. Subjects who require treatment with an aminoglycoside antibiotic, until treatment is complete. 3. For laryngeal injections, subjects must have a paradoxical vocal fold movement with intermittent stridor due to either gastroesophageal reflux or emotional disorders
