Relationship between physical activity, feelings of disability, and quality of life in patients with peripheral vestibular dysfunction

ABSTRACT Purpose: to verify the association of self-reported feelings of disability and physical activity with the impact of vestibular symptoms on the quality of life of patients with vestibular dysfunction. Methods: a retrospective, cross-sectional, analytical, documentary study approved by the Research Ethics Committee (evaluation report no. 4.462.519), with 50 selected medical records of patients diagnosed with peripheral vestibular dysfunction, including a survey of their medical history and results of the Dizziness Handicap Inventory (DHI). Results: the sample’s mean age was 55.38 years, and the majority were females (70%). The DHI revealed a moderate impact of dizziness. Physically active patients perceived less impact of the disease (p-value = 0.0167), while patients with feelings of disability, due to vestibular symptoms, had a greater damage of their quality of life (p-value = 0.0468). Conclusion: physical activity was associated with less damage of dizziness to the quality of life; also, a greater impact on the quality of life was associated with feelings of disability related to vestibular complaints.

摘要
目的：验证自我报告的残疾感受与体力活动，同前庭症状对前庭功能障碍患者生活质量的影响之间的关联。
方法：本研究为回顾性、横断面、分析性文献研究，已通过研究伦理委员会审批（审批报告编号：4.462.519），纳入50份确诊为外周性前庭功能障碍（peripheral vestibular dysfunction）患者的病历资料，收集其病史及眩晕残障量表（Dizziness Handicap Inventory, DHI）检测结果。
结果：本研究样本平均年龄为55.38岁，女性占比70%，为受试者多数。眩晕残障量表结果显示眩晕对患者存在中等程度影响。体力活动参与者感知到的疾病影响程度更低（p值=0.0167）；而因前庭症状产生残疾感受的患者，其生活质量受损程度更高（p值=0.0468）。
结论：本研究表明，体力活动与眩晕对患者生活质量的较低损害程度相关；同时，与前庭不适相关的残疾感受，亦与患者生活质量受影响程度更高相关。
