Effect of Vocal Exercise After Botulinum Toxin Injection for Spasmodic Dysphonia

Stopped early · Not applicable

Conditions studied: Spasmodic Dysphonia, Dystonia

In brief

Studies have suggested that voluntary muscle exercise in the hand and face after botulinum toxin injection may enhance the clinical effects of the toxin. Exercise may speed up the absorption of the toxin by the nerves and enhance the clinical response. This study will explore the effect of exercise on botulinum toxin injections for spasmodic dysphonia (SD).
