Anticholinergic drugs, such as Artane can be helpful in treating focal dystonia by affecting the transmission of messages from the brain to the muscles. Botulinum toxin injections may be used to compel the body to create new programs by blocking the nerve impulses to the contracting muscles. The injections temporarily weaken the muscle so that the spasm is reduced and a different wrist position is necessary to compensate for the relaxed muscle.
