Objectives: To investigate the perceptual, physiological, acoustic, and aerodynamic outcomes of patients with vocal nodules following intensive voice treatment compared with traditional voice treatment. Study Design: Pragmatic randomized clinical trial. Methods: Fifty-three women diagnosed with bilateral vocal nodules participated in the study. Voice recordings, stroboscopic recordings, acoustic, and aerodynamic assessments were made before voice treatment, after vocal hygiene education, and immediately postvoice treatment. All participants completed one session of vocal hygiene and eight sessions of direct voice therapy, however the delivery of the treatment between the two groups differed in treatment intensity. Results: Physiological improvements were observed after vocal hygiene alone, whereas physiological, perceptual, and acoustic parameters all improved to some degree in both treatment groups immediately posttreatment. There were no differences in the extent of change observed between the two groups at any point following treatment. Conclusions: The investigation provided initial evidence that individuals with vocal nodules are able to recover voice function, vocal health, and vocal communication through intensive voice treatment. The results suggest comparable positive perceptual, physiological, and acoustic outcomes from intensive voice therapy compared with traditional voice therapy. Further investigation is required to determine the long-term effects of intensive treatment.
