PACEMAKER FOR SPASMODIC DYSPHONIA

摘要

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.

1. A pacemaker system for a human subject having spasmodic dysphonia, the system comprising:
a sensing electrode configured to detect voice activity of the subject and to generate a first signal; a processor, in communication with the sensing electrode, configured to receive the first signal and to generate at least one stimulation parameter based on the first signal in order to activate a glottic closure reflex and to stimulate a recurrent laryngeal nerve or vagus nerve of the subject; a mechanical actuator configured to receive the at least one stimulation parameter and to activate the glottic closure reflex of the subject based on the at least one stimulation parameter; and a stimulating electrode configured to receive the at least one stimulation parameter and to activate the recurrent laryngeal nerve or the vagus nerve of the subject based on the at least one stimulation parameter.
