Torsion dystonia is a movement disorder that causes sustained, twisting involuntary movements. A severe form in children causes incapacitating, generalized muscle spasms. Before the use of high-dose trihexyphenidyl, there was no established therapy for the condition. Burke, Fahn, and colleagues led a clinical trial demonstrating that high-dosage anticholinergic therapy with trihexyphenidyl produced significant, sustained benefit for most patients. Anticholinergics remain a mainstay of treatment of this condition.
