MULTIPLE SCLEROSIS AND RELATED DISORDERS, cilt.82, 2024 (SCI-Expanded)
Background: Impairments in voice quality in Multiple Sclerosis (MS) have recently been investigated and different results were found. A voice-centered multidimensional assessment protocol with patient-reported outcome measures was conducted to evaluate all the aspects of the voice changes. Objectives: The study aimed to compare the objective, subjective, and perceptual measures of voice between the people with MS and the healthy control group.Methods: A total of 128 participants, including 64 people with MS age, and gender-matched healthy controls were enrolled in the study. Subjective, objective, and auditory-perceptual voice assessments of the participants were performed. The auditory-perceptual evaluation was performed with GRBAS. The Dysphonia Severity index was computed for both groups. All the participants completed the Turkish version of The Voice Handicap Index-10 (VHI-10) and the Voice-Related Quality of Life (VRQoL).Results: Acoustic and aerodynamic parameters of voice were found significantly different for both males and females between the MS and control group. DSI was found significantly different for both males and females in the MS group compared to the control group (p<0.05). All components of the GRBAS scale were significantly higher in the MS group (p<0.001). Using a multivariate regression model, it was determined that age, gender, EDSS score, number of MS attacks, and disease duration did not affect the DSI. The overall VHI-10 score was higher in the MS group (median=1.0 range= 0-28) and lower in the control group (median=0 range= 0-4). The mean VRQoL was lower in the MS group (median=95 range= 62.5-100) than in controls (median=100 range= 85-100) (p<0.001).Conclusion: Our results indicated that people with MS have significant differences in acoustic and aerodynamic parameters of voice compared to healthy individuals. A significant number of persons with MS are aware that their voice problem affects their quality of life. People with MS must be monitored for voice changes and a multidimensional voice assessment protocol should be implemented.
