Electronic control of pathologic tone disturbances in the larynx.

The complex anatomy of the larynx and the wide varieties of disturbances potentially affecting the tension of its constituent muscles give rise to various clinical presentations. Whatever the causes of pathologic tone disturbances affecting the larynx, rehabilitation should start by focusing on the dynamic adjustment of glottic tension in the muscles that have become separated from their respective central nervous system command centers. The objective of laryngeal rehabilitation is combined restoration of individual behaviors such that mutual, global relationships simulating those present before disability are reestablished.
