The aim of this study was to assess the therapeutic effectiveness of biofeedback, in a medical center’s routine for treating vestibular disorders, reducing emotional, functional, and physical disability at three-month follow-up. A total of 197 outpatients were recruited from a medical center to treat vestibular disorders. Patients in the control group received treatment as usual, consisting of one monthly visit with an otolaryngologist and pharmacological treatment specific for vertigo, while the experimental group attended biofeedback training. Patients in the experimental group received pharmacological therapy only in the phase before the start of biofeedback in order to stabilize the acute phase. During the three-month follow-up, the experimental group did not receive any booster sessions of biofeedback. At three-month follow-up there was a statistically significant difference between the groups, both in the mean total score of the dizziness handicap inventory and in the three subscales: physical, emotional, and functional. Moreover, the biofeedback group had reduced psycho-physiological parameters for all average values at three-month follow-up compared to the baseline. This is one of few studies assessing the effectiveness of biofeedback in a naturalistic setting for vestibular disorder treatment. The data confirmed that biofeedback can impact illness course, in terms of self-perceived disability reduction, assessed on emotional, functional, and physical aspects of daily living.

本研究的目的是评估生物反馈在医疗中心治疗前庭疾病的常规治疗中的治疗效果，并在三个月的随访中减少情绪、功能和身体残疾。医疗中心总共招募了 197 名门诊患者来治疗前庭疾病。对照组患者照常接受治疗，包括每月一次与耳鼻喉科医生就诊和针对眩晕的药物治疗，而实验组患者则参加生物反馈训练。实验组患者仅在生物反馈开始前阶段接受药物治疗，以稳定急性期。在三个月的随访期间，实验组没有接受任何生物反馈的加强课程。在三个月的随访中，各组之间在头晕障碍量表的平均总分以及身体、情绪和功能这三个分量表上都存在统计学上的显着差异。此外，与基线相比，生物反馈组在三个月的随访中所有平均值的心理生理参数均有所降低。这是评估生物反馈在自然环境下治疗前庭疾病有效性的少数研究之一。数据证实，生物反馈可以影响疾病进程，从自我感知的残疾减少角度，对日常生活的情绪、功能和身体方面进行评估。
