Delivery of Intensive Voice Therapy for Vocal Fold Nodules Via Telepractice: A Pilot Feasibility and Efficacy Study

Abstract

This pilot study examined voice outcomes and patient perceptions after intensive voice therapy for vocal fold nodules via telepractice. Pilot, within-subjects experimental trial. Participants included 10 women diagnosed with bilateral vocal fold nodules who received intensive voice treatment via a free videoconferencing platform Skype, (Microsoft Corp., Redmond, WA). All participants completed one vocal hygiene session in person, followed by eight sessions of therapy via telepractice over 3 weeks. Before and immediately after treatment, patients attended a clinic in person to complete perceptual, stroboscopic, acoustic, and physiological assessments of vocal function. Analyses were performed by a speech-language pathologist and an otolaryngologist independent to and blinded to the study. Participants also completed the Voice Handicap Index and a telepractice satisfaction questionnaire, or an anticipated satisfaction questionnaire, before and after the treatment. Significant improvements were found in perceptual, vocal fold function, acoustic, and physiological parameters as well as nodule sizes and patient perceptions of voice-related quality of life post-treatment. Participants were highly positive about their first experience with telepractice. Results were similar to those from a separate study investigating the effects of an intensive voice therapy delivered in conventional face-to-face (FTF) format. This study is consistent with possible benefits of telepractice in the delivery of intensive treatment for vocal fold nodules. Pending final verification with a FTF comparison group, telepractice could be recommended as an alternate treatment modality for patients with vocal fold nodules.
