Botulinum toxin A injection has been recently used in the treatment of spasmodic disorders and the focal dystonia for relieving its abnormal conditions. This treatment, however, is not popular in Korean because of difficulty in getting the drug. Se have injected Botulinum toxin A in 7 various patients;spasmodic torticollis:2, hemifacial spasm:3, blepharospasm:1, ankle spasticity:1. 3 patients improved greatly and 2 patients showed moderate, but 1 patient showed only mild improvement. No significant side effects showed except the transient ptosis in the blepharospasm and the mild focal muscle weakness in the hemifacial spasm.
