简要总结
This study aimed to compare the effectiveness of virtual reality (VR) and vestibular rehabilitation therapy (VRT) in enhancing balance in individuals with Persistent Postural-Perceptual Dizziness (PPPD). The experimental group received VR combined with VRT and optokinetic stimulation, while the control group received VRT and optokinetic stimulation. The study involved 42 individuals diagnosed with PPPD and administered ten intervention sessions over six weeks. The study also examined the impact of VR on various aspects of PPPD, including dizziness, visual vertigo, mental well-being, sleep quality, fall risk, and overall quality of life.
详细描述
Persistent Postural-Perceptual Dizziness (PPPD) represents a relatively new vestibular diagnosis that has garnered recent attention within the medical community. Consequently, there exists a pressing demand for efficacious and innovative management strategies. The primary purpose of this study was to assess the comparative effectiveness of virtual reality (VR) versus vestibular rehabilitation therapy (VRT) in enhancing balance among individuals afflicted with PPPD. A secondary purpose encompassed an investigation of VR's impact on various dimensions of PPPD, including dizziness, visual vertigo, mental well-being, sleep quality, fall risk, and overall quality of life. Materials and Methods: A cohort comprising forty-two individuals conclusively diagnosed with PPPD was randomly assigned to two distinct groups. The experimental cohort comprised twenty-one participants subjected to a combination of VR with optokinetic stimulation alongside VRT, whereas the control group, also consisting of twenty-one individuals, underwent solely optokinetic stimulation paired with VRT. The intervention sessions were administered twice weekly over a span of six weeks, resulting in a total of ten intervention sessions. Additionally, baseline and post-intervention assessments were conducted to gauge the efficacy of the interventions.

研究组 & 干预措施
Vestibular Rehabilitation Therapy (VRT)
Participants went through conventional VRT in addition to optokinetic exercise training. The VRT exercises were composed of gaze stabilization, head motion, and postural stability exercises with static and dynamic balance exercises. Ten repetitions of each VRT exercise were practiced in the same session for three sets. Moreover, participants were instructed to watch optokinetic stimulation videos. The optokinetic stimulation training was conducted using the following displays (a mobile and TV screen).

Virtual Reality
The same intervention program for the control group was implemented for participants in the experimental group, with the addition of using the VR split screen in Samsung Gear VR goggles in the last 4 sessions. Using the VR goggles, participants started watching the videos for 30 seconds to 1 minute in the sitting position in the first two sessions, followed by 1-2 minutes in the standing position for the last 2 sessions.

结局指标
主要结局
The Niigata Persistent Postural-Perceptual Dizziness Questionnaire (NPQ)
时间窗: After one year follow up.
self-reported questionnaire that was generated to screen for and assess the severity of Persistent Postural-Perceptual Dizziness. Higher score is worse severity of Persistent Postural-Perceptual Dizziness. Minimum score is 0 and maximum score is 72.
Dizziness Handicap Inventory (DHI)
时间窗: After 6 weeks
self- reported questionnaire that assesses the perceived disability from dizziness. Higher score indicates worse disability from dizziness. Minimum score is 0 and maximum score is 100.
Falls Efficacy Scale International (FES-I)
时间窗: After 6 weeks
self-reported questionnaire that assesses fear of falling. A higher score means worse concerns from falling. Minimum score is 16 and maximum score is 64.
Dynamic Gait Index (DGI)
时间窗: After 6 weeks
A clinical performance-based tool that is used to evaluate dynamic postural stability. A higher score indicates better dynamic balance and gait. Minimum score is 0 and maximum score is 24.
The Niigata Persistent Postural-Perceptual Dizziness Questionnaire (NPQ)
时间窗: Before intervention.
self-reported questionnaire that was generated to screen for and assess the severity of Persistent Postural-Perceptual Dizziness. Higher score is worse severity of Persistent Postural-Perceptual Dizziness. Minimum score is 0 and maximum score is 72.
