Trial Outcomes & Findings for Preliminary Study 2 to Test the Effects of Ambulatory Voice Biofeedback (NCT NCT03416868)

NCT ID: NCT03416868

Last Updated: 2024-04-17

Results Overview

Using a patient-specific voice measure, patients will be asked to avoid crossing numeric thresholds. The amount of voicing spent within desired thresholds will be the "percent compliance".

Measure
Standard of Care Voice Therapy With Ambulatory Voice Biofeedback.
Patients with Vocal Hyperfunction will undergo standard of care voice therapy, Ambulatory monitoring will be completed by the patients before therapy and throughout the first 3 weeks of therapy. Specifically, ambulatory monitoring will be worn by the patient for their 4 days with the most voicing during the first 3 weeks of therapy. Biofeedback will be activated only after the 2nd voice therapy session. Ambulatory voice biofeedback: Patients will be provided cues regarding their vocal behavior in daily life. Specifically, the patient will receive 100% feedback = a vibrotactile cue on a smartwatch every time the patient voices incorrectly. The specific objective voice measure for biofeedback will depend upon which measure is most strongly associated with improvements during voice therapy.

PRIMARY outcome

Timeframe: Week 1, Week 2, Week 3

Population: There is a discrepancy in the numbers of enrolled patients here (total = 7) and compared to total enrolled (total = 39). This is because the first 32 patients' data were used to refine and adapt study protocols. The final 7 patients were acquired with this final protocol.

Using a patient-specific voice measure, patients will be asked to avoid crossing numeric thresholds. The amount of voicing spent within desired thresholds will be the "percent compliance".
