Voice Therapy for Teachers With Voice Problems
Phase 3
Completed
- Conditions
- Phonotrauma
- Interventions
- Behavioral: Lessac-Madsen Resonant Voice TherapyBehavioral: Casper-Based Confidential Flow Therapy
- Registration Number
- NCT00222937
- Lead Sponsor
- University of Pittsburgh
- Brief Summary
The study compares two different forms of voice therapy, Lessac-Madsen Resonant Voice Therapy and Casper-Based Confidential Flow Therapy. The target population are teachers because they have the highest risk for developing voice problems. For this study the investigators are primarily interested in seeing if Lessac-Madsen Resonant Voice Therapy (LMRVT) and Casper-Based Confidential Flow Therapy (CBCFT) are equally effective at improving vocal functioning in teachers with phonotrauma, as assessed by the Voice Handicap Index (VHI).

- Any structural or functional change to the larynx that appears related to phonation,including bilateral or unilateral lesions (assuming normal overlying epithelium based on clinical examination), non-specific edema, or erythema that appear by clinical history related to phonation, or primary muscle tension dysphonia or other condition related to phonation without lesions
- No concurrent ear, nose and/or throat diagnoses, e.g. acute allergies, except for chronic allergies, sinusitis, and laryngopharyngeal reflux disease (LPR)
- No vocal fold hemorrhage
- No known degenerative medical conditions (e.g., degenerative neuromuscular disease, malignant process undergoing treatment or with less than 5 years remission, uncontrolled systemic disease (e.g., auto immune disease, or hormonal condition)
- Normal hearing to 30 dB at 1000Hz - 3000Hz in the better ear
- The participant is able to start therapy within 6 weeks of the initial evaluation and can be scheduled for 8 sessions (two per visit) in a 6-week time period
- Agreement by the participant to provide information regarding days missed from work during the previous year and the year following treatment
Exclusion Criteria
- Known degenerative medical condition
- Concurrent ear-nose-throat diagnosis, e.g., acute allergies (but chronic allergies, sinusitis, and laryngopharyngeal reflux disease (LPR) are not exclusion criteria) and vocal fold hemorrhage
- Degenerative medical conditions that would exclude a participant from participation include, but are not limited to: degenerative neuromuscular disease, malignant process undergoing treatment or with less than 5 years remission, uncontrolled systemic disease (e.g. auto immune disease), or hormonal condition.
