Abstract
ABSTRACT Purpose: to verify whether there is a correlation between tinnitus sensation and repercussion on the quality of life and craniocervical posture in teachers, participating in the Pró-Mestre project. Methods: a cross-sectional study with a sample of 90 teachers, mean age of 47.70 years, who responded to the Craniocervical Dysfunction Index (CDI), to verify the craniocervical posture, the analog visual scale (AVS), and the Portuguese adaptation of the Tinnitus Handicap Inventory (THI), to investigate tinnitus and its impact on the quality of life. Appropriate statistical tests were applied, by adopting a significance level lower than 0.05. Results: out of the 90 teachers, 18 (20%) had tinnitus. There was a statistically significant difference between the sensation of tinnitus, according to the AVS and the craniocervical posture (CDI) in teachers (p <0.001). There was also an association between tinnitus complaint and right-rotation range of motion, with age and right lateral tilt being independent factors, regarding teachers' tinnitus sensation. In the correlation of the THI (total and domains), there was an association with cervical mobility, only in the left inclination. Conclusion: since a statistically significant difference was found between the subjective sensation of tinnitus and the craniocervical posture with a correlation between tinnitus sensation and repercussion on the quality of life and craniocervical posture in teachers, these aspects should be considered in the assessment of teachers presented with tinnitus, as well as further studies with a population of teachers, healthy adults, in order to increase the knowledge on the subject.
Highlights
Teaching is one of the professional activities with the greatest social relevance, especially in basic education
When the Tinnitus Handicap Inventory (THI) was correlated with the angulations of the six cervical mobility variables, only the lateral inclination (L) was negatively correlated with the total THI and the functional domain THI. These findings should be interpreted with caution, and further studies should be encouraged with healthy adults, and with teachers, with different sensory conditions in order to deepen the knowledge about tinnitus and cervical disorders in this population
The experimental replication of tinnitus points to a prominent role of the upper posterior cervical muscle groups, combining with animal experiments, in conjunction with other triggering factors, including psychological factors. Such statements are consistent with the present study, as this study found an association between tinnitus sensation and cervical mobility
Summary
Teaching is one of the professional activities with the greatest social relevance, especially in basic education It generally poses challenging working conditions for teachers, with possible implications for their physical and mental health[1,2,3], and with an impact on professional performance, which is fundamental for the success of the teaching process[2]. Tinnitus is an auditory symptom with an abnormal perception of sounds in which there is an auditory sensation perceived by the subject, in the absence of a sound stimulus coming from the environment It can be either objective or subjective and is usually differentiated based on the person’s overall history, in the physical examination, and audiogram[6]. Classifying the type, quality, and intensity of tinnitus is useful to its assessment and treatment – which may include cognitive-behavioral therapy, tinnitus retraining therapy, sound therapy, hearing aids, cochlear implants, pharmacotherapy, and brain stimulation[6,7,8,9,10,11]
