Abstract
A stimulation system and method for treating to a human subject having spasmodic dysphonia includes a sensing electrode configured to detect voice activity of a vocalizing muscle of the subject and to generate a first signal, and a processor configured to receive the first signal from the sensing electrode and to generate at least one stimulation parameter based on the first signal. The system further includes a mechanical actuator configured to receive the stimulation parameter from the processor and to activate a glottic closure reflex of the subject in response to the stimulation parameter and a stimulating electrode configured to receive the stimulation parameter from the processor and stimulate the recurrent laryngeal nerve or the vagus nerve of the subject based on the stimulation parameter.
