Treatment of myoclonic dystonia with transcutaneous electrical nerve stimulation.

The use of a transcutaneous nerve stimulator yielded positive results in a condition marked by involuntary movements (tremors and myoclonias) and dystonia. In the absence of clues to the pathophysiology of the myoclonus and dystonia, it is argued that transcutaneous stimulation induces an action on the neurotransmitters that inhibits neuromuscular function.
