Treatment of Involuntary Movements (Dystonia, Tremor, Tic)

Botulinum toxins, after injection into the muscle, block the release of acetylcholine from the neuromuscular junction. Acetylcholine is a chemical neurotransmitter that, upon release from nerve endings, activates the muscles. In disease conditions characterized by presence of overactive muscles with involuntary movements (dystonias, tremors, tics), injection of the botulinum toxin into the affected muscles decreases the involuntary movements substantially and improves the patients’ quality of life.
