Unlocking the Potential of VAST.Rehab in Vestibular Rehabilitation
Introduction
Vestibular rehabilitation is a specialized therapy aimed at improving balance, reducing dizziness, and enhancing spatial orientation in individuals with vestibular disorders. Traditionally, this therapy involves exercises that challenge gaze stabilization, postural control, and sensory integration. However, with the advent of immersive technologies, virtual reality (VR) and full-body motion tracking have opened new possibilities for personalized, engaging, and data-driven rehabilitation.
Although VAST.Rehab was not originally developed for vestibular rehabilitation, its modular structure, sensor-based feedback, and immersive design make it a promising tool to support vestibular therapy. With compatibility across Meta Quest 3, 3D full-body tracking via camera systems, and stabilometric platforms, VAST.Rehab offers a flexible environment for clinicians to adapt existing modules to vestibular needs.
Potential of VAST.Rehab in Vestibular Therapy
Balance and Postural Control
Modules such as Weight Distribution Tests and Romberg Assessments measure sway, deviation, and velocity with eyes open and closed. Real-time feedback and customizable difficulty levels allow therapists to tailor balance challenges to each patient’s tolerance. Metrics like EC/EO area ratio, velocity deviation, and center of pressure provide objective insights into progress.
Dynamic Movement and Gaze Stabilization
Tasks like Movement Time Dynamic Test, Tracking, and Pendulum require patients to follow moving targets while maintaining posture - ideal for training the vestibulo-ocular reflex (VOR). Full-body tracking ensures accurate measurement of head, trunk, and limb coordination.
Functional Movement Simulations
Tasks such as Runaway, Airplane, and Kitchen simulate real-world scenarios requiring spatial awareness, reaction to stimuli, and dynamic balance. The VR environment with hand tracking challenges patients to move through 3D spaces, improving their ability to navigate safely in daily life.
Cognitive-Motor Integration
Tasks like Divided Attention Sorter and Problem Solving Clones combine movement with cognitive load, mimicking real-life multitasking situations. This is particularly beneficial for patients with vestibular migraines or central vestibular dysfunctions.
Customizability and Progress Tracking
Each module includes adjustable parameters: duration, range, speed, object spacing, and difficulty. Therapists can monitor metrics such as reaction time, accuracy, movement precision, and balance deviation over time.
Clinical Integration of VAST.Rehab
VAST.Rehab’s modules are actively used to assess and improve key aspects of vestibular function. The system provides measurable data and interactive tasks that reflect real-world challenges faced by patients with balance and spatial orientation issues.
For example, the Romberg Test module evaluates postural stability with eyes open and closed, offering detailed metrics such as sway area, path length, and velocity. These indicators help clinicians monitor progress and detect subtle improvements in sensory integration.
The Unterberger’s Test simulates blind walking in place, measuring angular deviation and step symmetry—critical for diagnosing unilateral vestibular dysfunction. VAST.Rehab enhances this test with visual feedback and precise tracking.
In dynamic tasks like Stability Test or Balance Grid, patients are challenged to maintain equilibrium while responding to shifting stimuli. These exercises mimic everyday situations such as walking in crowded environments or navigating uneven terrain.
By integrating these modules into therapy, clinicians can create personalized programs that combine diagnostic precision with functional training, ensuring that rehabilitation is both effective and engaging.
Evidence-Based Validation of VAST.Rehab
While VAST.Rehab has not been directly studied in vestibular rehabilitation, recent research supports the use of virtual reality and gamified environments in this field:
- A 2025 randomized controlled trial published in Frontiers in Neurology found that VR-based therapy significantly improved balance confidence and reduced dizziness handicap in patients with acute unilateral vestibulopathy. The VR group showed faster improvement in the physical domain of the DHI and ABC scales.
- A 2023 meta-analysis in European Archives of Oto-Rhino-Laryngology reviewed six controlled trials and concluded that VR interventions significantly improved scores on the DHI, Vertigo Symptom Scale, Visual Analogue Scale, and posturography. The authors emphasized VR’s clinical benefit in treating peripheral vestibular dysfunction.
- A 2023 study in the Journal of Otolaryngology - Head & Neck Surgery evaluated commercially available VR video games. Physiotherapists rated VR Tunnel Race and VR Real World Bike Racing as highly congruent with vestibular rehabilitation exercises, especially for habituation and gaze stabilization.
These findings align with VAST.Rehab’s immersive, repetitive, and task-specific modules, which are built on motor learning principles and designed to promote neuroplasticity and patient engagement.
Conclusion
Although VAST.Rehab does not include a dedicated vestibular rehabilitation module, its immersive design, full-body tracking capabilities, and diverse therapeutic tasks make it a valuable complementary tool in this domain. By leveraging movement precision, balance training, and cognitive-motor integration, VAST.Rehab can support key aspects of vestibular therapy - especially when personalized and guided by a clinician.
The system’s adaptability allows therapists to repurpose existing modules to simulate vestibular challenges, track progress, and maintain patient engagement. As research continues to validate the role of virtual reality in neurorehabilitation, platforms like VAST.Rehab offer a flexible and innovative way to enhance traditional vestibular therapy protocols.
