Brief Summary

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).

Study Arms (2)

12 Exercise Sessions

EXPERIMENTAL

Patients will receive 12 treatment sessions with flow phonation exercises, as well as education on vocal hygiene.

Behavioral: Vocal Hygiene TrainingBehavioral: Flow Phonation Exercises

6 Hygiene and 6 Exercise

ACTIVE COMPARATOR

Patients will receive 6 sessions of vocal hygiene training for initial comparison to patients in Arm 1. They will then receive 6 sessions of vocal exercise training and vocal hygiene training combined.

Behavioral: Vocal Hygiene TrainingBehavioral: Flow Phonation Exercises

Interventions

Patients will receive education on how to care for their voices on three factors: 1) hydration, 2) exogenous inflammation control, and 3) abstinence of yelling and screaming.

12 Exercise Sessions6 Hygiene and 6 Exercise

Three exercises are employed: gargling, cup bubble blowing, and stretch and flow (tissue blowing). Each is done without voicing, with voicing, and then with variations in pitch and verbalization.
