We aimed to explore the role of comprehensive vestibular rehabilitation based on virtual reality (VR) technology in residual symptoms after canalith repositioning procedure.
A total of 124 patients, who were diagnosed with benign paroxysmal positional vertigo from September 2020 to July 2023 and had residual symptoms 24 hours after the canalith repositioning procedure, were selected as the subjects. They were randomly divided into a normal control (NC) group, a Cawthorne-Cooksey exercise group (n=41), a Brandt-Daroff exercise group (n=41), and a VR group (n=42). The NC group received no intervention, the Cawthorne-Cooksey exercise group underwent Cawthorne-Cooksey exercise, the Brandt-Daroff exercise group was subjected to Brandt-Daroff exercise, and the VR group was given comprehensive vestibular rehabilitation based on VR technology.
After treatment, the Dizziness Handicap Inventory (DHI) and vestibular symptom index (VSI) scores of the virtual reality (VR), Cawthorne-Cooksey exercise, and Brandt-Daroff exercise groups were significantly lower than those of the NC group (P <.05). The scores of the VR group were lower than those of the Cawthorne-Cooksey exercise and Brandt-Daroff exercise groups (P < .05). The abnormality rates of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in VR, Cawthorne-Cooksey exercise, and Brandt-Daroff exercise groups were lower than those of the NC group (P <05). The rates of the VR group were lower than those of the Cawthorne-Cooksey exercise and Brandt-Daroff exercise groups (P <05).
Comprehensive vestibular rehabilitation based on VR technology can cure the residual symptoms after the canalith repositioning procedure, reduce the abnormality rates of oVEMP and cVEMP, and reconstruct the balance ability.
本研究旨在探讨基于虚拟现实（VR）技术的综合前庭康复在耳石复位术后残余症状中的作用。
选择 2020 年 9 月至 2023 年 7 月期间被诊断为良性阵发性位置性眩晕且耳石复位术后 24 小时仍有残余症状的 124 例患者作为研究对象。将患者随机分为正常对照组（NC 组）、Cawthorne-Cooksey 运动组（n=41）、Brandt-Daroff 运动组（n=41）和 VR 组（n=42）。NC 组不进行任何干预，Cawthorne-Cooksey 运动组进行 Cawthorne-Cooksey 运动，Brandt-Daroff 运动组进行 Brandt-Daroff 运动，VR 组则进行基于 VR 技术的综合前庭康复。
治疗后，VR、Cawthorne-Cooksey 运动和 Brandt-Daroff 运动组的眩晕残障程度量表（DHI）和前庭症状指数（VSI）评分均显著低于 NC 组（P<0.05），VR 组的评分低于 Cawthorne-Cooksey 运动和 Brandt-Daroff 运动组（P<0.05）。VR、Cawthorne-Cooksey 运动和 Brandt-Daroff 运动组的眼震电图（oVEMP）和颈肌前庭诱发肌源性电位（cVEMP）异常率均低于 NC 组（P<0.05），VR 组的异常率低于 Cawthorne-Cooksey 运动和 Brandt-Daroff 运动组（P<0.05）。
基于 VR 技术的综合前庭康复可治愈耳石复位术后残余症状，降低 oVEMP 和 cVEMP 异常率，重建平衡能力。
