Vestibular Dizziness
Conditions
Brief summary
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.
Detailed description
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.
Interventions
The VRT exercises were composed of gaze stabilization, head motion and postural stability exercises with static and dynamic balance exercises.
The VR exercises included watching theraputic videos using the virtual reality goggles with static and dynamic balance exercises.
OTHEROptokinetic Stimulation exercises
Optokinetic Stimulation is a type of visual stimulation used to improve visual function and balance in patients with vestibular disorders.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Niigata Persistent Postural-Perceptual Dizziness Questionnaire (NPQ) | 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. |
| Dizziness Handicap Inventory (DHI) | Before intervention. | 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) | Before intervention. | 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) | Before intervention. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hospital Anxiety and Depression Scale (HADS) | Before intervention. | a self-assessment scale that was developed to assess the severity of mood disturbances including depression and anxiety. Higher scores mean worse severity in depression and anxiety. Minimum score is 0 and maximum score is 21 for each subscale (depression and anxiety). |
| Medical Outcomes Study Short Form 12 (SF-12) | Before intervention. | A self-reported questionnaire that assesses the impact of any health condition on the quality of life. Higher scores indicate better quality of life. Minimum score is 0 and maximum score is 100. |
| Pittsburgh Sleep Quality Index (PSQI) | Before intervention. | A self-reported questionnaire that assesses quality of sleep. A higher score indicates worse sleep quality. Minimum score is 0 and maximum score is 21. |
