Abstract

Aim: to characterize the vocal impact of subjects with multiples clerosis in their voice-related quality of life, identifying vocal symptoms, as well as symptoms of anxiety, depression and vocal fatigue. Methods: Were recruited Fifteen subjects from both genders whoattended the HUCAM neurology outpatient clinic. The subjects were evaluated independent of the presence of a demyelinating outbreak to perform perceptual-auditory assessment of voice, Quality of Life in Voice, Vocal Disadvantage Index, Vocal Fatigue Index, Beck Anxiety Inventory and Beck Depression Inventory at different times, repeating the proposed protocol. Results: The comparison of the self-assessment data after Five months showed statistically significant changes in the IDV, QVV, IFV and perceptual-auditory evaluation protocols in the Asthenia, Strain and Instability domains. There was continuation of the limitation and slow talk in theree valuation, and the subjects began to present sensory symptoms, which was not observed  in the first contact. Conclusion: it was detected that there is vocal alteration mainly manifested by asthenia, strain and instability. The subjects present an impact on voice quality of life, vocal fatigue in the domains of fatigue and vocal restriction and physical discomfort associated with voice, and worsening of vocal disadvantage throughout the course of the disease.
