Preliminary Studies to Test the Effects of Ambulatory Biofeedback in Small Groups of Patients With Vocal Hyperfunction: Study 3
Vocal hyperfunction (VH) is the most commonly treated class of voice disorders by speech-language pathologists and voice therapy is the primary curative treatment. Patients and clinicians report that generalizing improved voicing into daily life is the most significant barrier to successful therapy. We will test if extending biofeedback into the patient's daily life using ambulatory voice monitoring will significantly improve generalization during therapy and if individual patient factors, like how easily they can modify their voice and engagement during therapy, moderate the effects of the biofeedback.
• Diagnosis of vocal fold nodules and polyps.
• Secondary diagnosis of laryngopharyngeal reflux (LPR) or gastro-esophageal reflux disease (GERD)
• Secondary diagnoses commonly associated with phonotrauma like erythema, edema, varies, ectasia, laryngitis, secondary/reactive muscle tension dysphonia (MTD), hemorrhage, etc.
• Diagnosis of primary MTD.
• Allowable secondary diagnoses are LPR and GERD.
