Treating Laryngeal Hyperfunction With Flow Phonation

Status unconfirmed · Not applicable

Conditions studied: Muscle Tension Dysphonia

In brief

The purposes of the proposed study are: a) to determine whether Flow Phonation can decrease Laryngeal Resistance (Rlaw) in patients with Muscle Tension Dysphonia (MTD); and b)establish the relationship between changes in measures of Rlaw and phonatory airflow to endoscopic, perceptual, acoustic, and handicap assessment ratings. MTD can have a debilitating effect on individuals who rely on their voices the most-teachers, preachers,salespeople, singers-costing them time, money, and even their jobs. It can lead to vocal fatigue, pain, and complete loss of voice. While treatments have emerged with some promising effects, no treatments have proven to have long-term benefits to all patients. Our preliminary data demonstrate Flow Phonation training resulted in significant decreases in Laryngeal Resistance to phonatory airflow with associated improvements in voice quality and voice handicap ratings. Sample size for our pilot study was small; no control group was utilized; and outcome measures were limited. In the proposed investigation, a larger sample will be obtained, a control group of participants receiving only Vocal Hygiene Training will be used for comparison during the first 3 weeks, and a wider range of outcome measures will be included over a longer period of time (1 year).
