Description of intervention(s) / exposure
Botulinum Toxin Type A (BoNT-A) for idiopathic cervical dystonia. BoNT-A is able to stop nerves stimulating muscles thus providing a way of relaxing muscles. BoNT-A is administered by intramuscular injections with a duration of action of between 12 to 16 weeks. Observations will be made at 3-6 weeks post injection and again at the time of re-injection (12-16 weeks). The dosage given to the patient will be at the clinician's discretion.
