Preliminary Study 2 to Test the Effects of Ambulatory Voice Biofeedback
Vocal Fold Nodules, Muscle Tension Dysphonia

About this trial
This is an interventional treatment trial for Vocal Fold Nodules focused on measuring Ambulatory, Biofeedback, Voice
Eligibility Criteria
Inclusion Criteria:
- Patients with vocal fold nodules or muscle tension dysphonia undergoing voice therapy
Exclusion Criteria:
- If a patient's baseline ambulatory monitoring data is not at least 1 standard deviation away from a normative database in any measure, he/she will be excluded. Non-English speakers are excluded because prompts on the smartphone app are only available in English.

For the first two weeks of voice therapy, patients will receive ambulatory voice monitoring (no biofeedback) during their voice therapy sessions and throughout the week. In the following 3 weeks of voice therapy (weeks 3 through 5), patients in this arm will be provided ambulatory voice biofeedback. Week 6 involves monitoring without feedback in all subjects to evaluate "washout" and any effect of feedback dose. Monitoring per week: 20 minutes of phonation time after the therapy session (Day 1), 40 minutes of phonation time for each of the next consecutive two days (Days 2 and 3), and 40 minutes of phonation time for the day before the patient's subsequent voice therapy session (Day 4). During biofeedback weeks, feedback will be enabled only on Days 1 and 2.

Monitoring per week: 20 minutes of phonation time after the therapy session (Day 1), 40 minutes of phonation time for each of the next consecutive two days (Days 2 and 3), and 40 minutes of phonation time for the day before the patient's subsequent voice therapy session (Day 4). During biofeedback weeks, feedback will be enabled only on Days 1 and 2.
For the first four weeks of voice therapy, patients will receive ambulatory voice monitoring (no biofeedback) during their voice therapy sessions and throughout the week. In voice therapy week 5, patients in this arm will be provided ambulatory voice biofeedback. Week 6 involves monitoring without feedback in all subjects to evaluate "washout" and any effect of feedback dose. Monitoring per week: 20 minutes of phonation time after the therapy session (Day 1), 40 minutes of phonation time for each of the next consecutive two days (Days 2 and 3), and 40 minutes of phonation time for the day before the patient's subsequent voice therapy session (Day 4).
