Biofeedback Treatment & Voice Disorders
Biofeedback in voice treatment involves the use of an external device--often a video monitor--to feed patients real-time, physiological information about their own voice production that is normally unapparent to the patient. The patient is then trained to interpret the information and to stabilize unstable, problem areas during speech.
How Biofeedback Works
When the patient is able to see clear, simple and reliable images of the mechanics of his own voice production, he then may be able to rectify specific problems with exercises and other therapeutic guidance.
Electromyography of Vocal Muscles
Electromyography produces a videoendoscopic image of muscle activity near and around the vocal folds.
Imaging the Vocal Folds
Electromyographic video images of the vocal folds show the folds' movement during speech, giving the patient continuous feedback during exercises and therapy.
Acoustic Therapy
Acoustic therapy is a biofeedback technique that indicates pitch, volume and voice quality. Some patients with volume disorders are encouraged to carry the biofeedback device daily to help with everyday speech.
Paradoxical Vocal Fold Movement (PVFM)
In the treatment of PVFM--involuntary closing of the vocal folds--the patient is shown a videoendoscopic image of his vocal folds' behavior while breathing.
Dysphonia
Electromyographic biofeedback is increasingly being used in the treatment of dysphonia, a common disorder that gives the voice a tense and squeezed sound.
