Comparison of Vocal Fatigue in Speech Therapists With Other Rehabilitation Therapists

Published:February 16, 2021DOI:



      Voice, as one of the most important communication tools in humans, can cause many problems in a person's daily life if it is damaged. One type of voice complaint is vocal fatigue, which is common among people who use their voices a lot. Rehabilitation therapists may be more vulnerable to a variety of vocal disorders and complaints due to extensive voice use and long-term relationships with clients. The aim of this study is to investigate and compare vocal fatigue among therapists in Ahvaz rehabilitation fields.


      This cross-sectional, descriptive-analytical study was performed on 100 therapists in Ahvaz rehabilitation fields. For this purpose, the Persian version of the vocal fatigue index questionnaire has been used. One Way Anova parametric tests were used to compare target variables. The relationship between vocal fatigue and work experience and working hours per day was calculated using Spearman correlation coefficient.


      A comparison of the scores of the vocal fatigue index in the rehabilitation therapists showed that there was a significant difference between the therapists scores in the field of speech therapy and the therapists scores in other fields (P < 0.05).


      Due to the nature of rehabilitation fields and the use of voice during daily interactions with different clients, especially clients with special disabilities, the possibility of voice disorders and complaints in this population should be considered. Therefore, providing the necessary training for voice care and voice health of this population should be noted in order to prevent voice disorders and complaints
