Examining Use and Effectiveness of Teletherapy for Patients with Dysphonia

Virtual therapy (teletherapy) for patients with dysphonia has become ubiquitous in the COVID-19 era. However, barriers to widespread implementation are evident, including unpredictable insurance coverage attributed to limited evidence supporting this approach. In our single-institution cohort, our objective was to show strong evidence for use and effectiveness of teletherapy for patients with dysphonia.

Single institution, retrospective cohort study.

This was an analysis of all patients referred for speech therapy with dysphonia as primary diagnosis from 4/1/2020 to 7/1/2021 and in whom all therapy sessions were delivered in a teletherapy format. We collated and analyzed demographics and clinical characteristics and adherence to the teletherapy program. We assessed changes in perceptual assessments and vocal capabilities (GRBAS, MPT), patient-reported outcomes (V-RQOL), and metrics of session outcomes (complexity of vocal tasks, carry-over of target voice) pre- and post-teletherapy using student's t test and chi-square test.

Our cohort included 234 patients (mean [SD] age 52 [20] years) residing a mean (SD) distance of 51.3 (67.1) miles from our institution. The most common referral diagnosis was muscle tension dysphonia (n = 145, 62.0% patients). Patients attended a mean (SD) of 4.2 (3.0) sessions; 68.0% (n = 159) of patients completed four or more sessions and/or were deemed appropriate for discharge from teletherapy program. Statistically significant improvements were seen in complexity and consistency of vocal tasks with consistent gains in carry-over of target voice for isolated tasks and connected speech.

Teletherapy is a versatile and effective approach for treatment of patients with dysphonia of varying age, geography, and diagnoses.
