Background Peripheral vestibular disorders are common disorders among population with increased prevalence with age advancement, manifested by balance disorders and postural instability that negatively affect daily activities and social participation. Objectives To investigate the effect of transmastoidal galvanic stimulation added to a designed vestibular rehabilitation program on recovery outcomes in Egyptian patients with unilateral peripheral vestibular disorders. Subjects and methods Forty patients (from both sexes) diagnosed with unilateral peripheral vestibular weakness were evenly and randomly designated into two groups: study and control groups. The study group received transmastoidal galvanic stimulation, in addition to a vestibular rehabilitation program, whereas control group undergone vestibular rehabilitation program only. Treatment sessions were conducted three times weekly for four successive weeks. Assessment of vestibular canal weakness was carried out using videonystagmography, postural stability using computerized posturography, while participation in daily activities was carried out using Vestibular Disorders Activities of Daily Living Scale (VADL). All assessment measures were carried out pre- and post-treatment. Results Study group showed improvement of post-treatment scores of canal weakness, postural stability parameters, and VADL scale in reverse to control group that showed improvement of scores of preference and VADL only. A statistically significant difference was found between both groups in post-treatment scores of canal weakness, total equilibrium composite, and vestibular component with more improvement in the study group. Conclusion Adding transmastoidal galvanic stimulation to vestibular rehabilitation exercises for unilateral peripheral vestibular disorders improves the recovery outcomes of vestibular canal weakness, equilibrium, and vestibular components of postural stability.

经乳突电流刺激对单侧外周前庭障碍患者恢复结果的疗效：一项随机对照试验

背景外周前庭障碍是人群中常见的疾病，随着年龄的增长患病率增加，表现为平衡障碍和姿势不稳定，对日常活动和社会参与产生负面影响。目的 研究经乳突电流刺激添加到设计的前庭康复计划中对埃及单侧外周前庭障碍患者恢复结果的影响。受试者和方法 将 40 名诊断为单侧外周前庭肌无力的患者（来自男性和女性）均匀随机分为两组：研究组和对照组。除了前庭康复计划外，研究组还接受了经乳突电刺激，而对照组仅接受了前庭康复计划。每周进行三次治疗，连续四个星期。使用视频眼震描记法评估前庭管无力，使用计算机姿势描记法评估姿势稳定性，同时使用前庭疾病日常生活活动量表 (VADL) 进行日常活动的评估。所有评估措施均在治疗前和治疗后进行。结果 研究组显示治疗后根管无力评分、姿势稳定性参数和 VADL 评分的改善，与仅显示偏好评分和 VADL 评分改善的对照组相反。两组在治疗后根管无力、总平衡综合和前庭成分评分方面存在统计学显着差异，研究组的改善更多。结论 在单侧外周前庭障碍的前庭康复训练中加入经乳突电流刺激可改善前庭管无力、平衡和姿势稳定性的前庭成分的恢复结果。试验注册 临床试验识别号 (NCT04010435)。2019 年 3 月 7 日注册——追溯注册，https://register.clinicaltrials.gov/prs/app/action/LoginUser?ts=1&cx=-jg9qo4
