Comparative study of sensation and repercussion of tinnitus on the quality of life and craniocervical posture in teachers

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摘要 目的：旨在验证参与Pró-Mestre项目的教师群体中，耳鸣主观感受与生活质量影响及颅颈姿势之间是否存在相关性。 方法：本研究为横断面研究，纳入90名教师作为研究样本，平均年龄为47.70岁。所有受试者均完成颅颈功能障碍指数（Craniocervical Dysfunction Index, CDI）以评估颅颈姿势、视觉模拟量表（Analog Visual Scale, AVS），以及葡萄牙语适配版耳鸣障碍问卷（Tinnitus Handicap Inventory, THI），以调查耳鸣情况及其对生活质量的影响。本研究采用显著性水平低于0.05的恰当统计学检验方法开展数据分析。 结果：90名教师中共有18人（20%）存在耳鸣症状。根据AVS评估的耳鸣主观感受与教师的颅颈姿势（CDI评估结果）之间存在统计学意义上的显著差异（p
