Persistent postural-perceptual dizziness (PPPD) is a newly defined disorder characterized by functional dizziness. Due to its recent discovery, definitive treatment for PPPD has not been established; therefore, this study aimed to assess the effectiveness of virtual reality (VR)-guided, dual-task, trunk balance training for the management of PPPD using the mediVR KAGURA system.
We analyzed data of patients who presented with PPPD from January 1, 2021, to February 28, 2021. The VR group included patients who underwent mediVR KAGURA-guided training for 100 tasks (10 min). Patients with PPPD who received standard treatment and rehabilitation were assigned to the control group. Equilibrium tests were performed at baseline and immediately after mediVR KAGURA-guided training to examine its effectiveness in improving static and dynamic balance. Additionally, clinical questionnaires related to balance disorders were administered at baseline and 1 week after mediVR KAGURA-guided training to examine its effects on balance-related symptoms. The primary outcome was improvements in static and dynamic balance and Niigata PPPD Questionnaire (NPQ) scores.
VR-guided training using mediVR KAGURA improved objective outcomes, including static and dynamic postural stability, after a single 10-min training session. Additionally, mediVR KAGURA-guided training improved scores on the Hospital Anxiety and Depression Scale and NPQ 1 week after the 10-min training session.
VR-guided training using mediVR KAGURA represents a viable method for managing balancing ability, anxiety, and symptoms in patients with PPPD. Such training provides a safe and cost-effective solution for PPPD management. Further studies are required to evaluate the clinical efficacy of this strategy.

持续性姿势感知性头晕（PPPD）是一种新定义的疾病，其特征为功能性头晕。由于其最近才被发现，因此尚未确定 PPPD 的明确治疗方法；因此，本研究旨在使用 mediVR KAGURA 系统评估虚拟现实（VR）引导的双重任务躯干平衡训练对 PPPD 的管理效果。
我们分析了 2021 年 1 月 1 日至 2021 年 2 月 28 日期间出现 PPPD 的患者的数据。VR 组包括接受 mediVR KAGURA 引导训练 100 次任务（10 分钟）的患者。接受标准治疗和康复的 PPPD 患者被分配到对照组。在基线和 mediVR KAGURA 引导训练后立即进行平衡测试，以检查其改善静态和动态平衡的效果。此外，在基线和 mediVR KAGURA 引导训练后 1 周进行与平衡障碍相关的临床问卷，以检查其对平衡相关症状的影响。主要结局为静态和动态平衡以及新泻 PPPD 问卷（NPQ）评分的改善。
单次 10 分钟训练后，使用 mediVR KAGURA 的 VR 引导训练改善了客观结果，包括静态和动态姿势稳定性。此外，meviVR KAGURA 引导训练在 10 分钟训练后 1 周改善了医院焦虑和抑郁量表以及 NPQ 的评分。
使用 mediVR KAGURA 的 VR 引导训练为管理 PPPD 患者的平衡能力、焦虑和症状提供了一种可行的方法。这种训练为 PPPD 管理提供了一种安全且具有成本效益的解决方案。需要进一步研究来评估该策略的临床疗效。
