Abstract
The objective of the study was to analyze the outcome of the proprioceptive-elastic (PROEL) voice therapy method in patients with functional dysphonia (FD). Fifty-two patients with FD were involved in the study; they were composed of three subgroups of patients with (1) FD without glottal insufficiency (n = 28), (2) FD and glottal insufficiency (n = 9), and (3) FD, glottal insufficiency, and vocal nodules (n = 15). A multidimensional assessment protocol including videolaryngostroboscopy; maximum phonation time; perceptual evaluation of dysphonia with the Grade, Instability, Roughness, Breathiness, Asthenia, and Strain (GIRBAS) scale; and 10-item version of the Voice Handicap Index was conducted before and after 15 sessions of voice therapy. All voice therapy sessions were conducted by the same speech-language pathologist. The comparison between voice assessment before and after voice therapy with the PROEL method in patients with FD, in all the three subgroups, revealed a statistically significant improvement in periodicity and the mucosal wave in the laryngostroboscopy, maximum phonation time, GIRBAS scale scores, and VHI-10. Voice of patients with FD improved after treatment with the PROEL method. Further studies are needed to analyze the efficacy of the PROEL method with randomized double-blind clinical trials using different methods for voice therapy. At present, the PROEL method represents an alternative tool for the speech pathologist to improve voice in patients with FD.
