Virtual Reality Therapy
What Is It?
Plain-Language Explanation
Virtual Reality Therapy uses a VR headset to place you inside a simulated environment designed for recovery practice. You might reach for objects, walk through a virtual corridor, or solve memory puzzles — all in a safe, controlled setting that can be adjusted to your ability level.
The brain does not fully distinguish between real and convincing simulated movement, so VR practice activates the same neural pathways as actual movement. This is especially valuable when full physical movement is not yet possible.
Technical Explanation
VR therapy leverages activity-dependent neuroplasticity through immersive environments that deliver integrated visual-vestibular-proprioceptive feedback. Medical-grade VR systems (head-mounted displays with ≥90 Hz refresh rate, <20 ms latency) minimise motion sickness and enable graded motor tasks with adjustable difficulty.
In post-stroke rehabilitation, VR drives cortical remapping through repeated task-specific practice, exploiting Hebbian plasticity in motor cortex and cerebellum. Integrated motion sensors (IMU, haptic controllers) enable objective quantification of movement quality parameters — velocity, accuracy, smoothness — as rehabilitation progress biomarkers.
How It Is Used at Our Practice
We use clinically validated VR rehabilitation platforms for structured 20–40 minute sessions. Programmes are tailored to the specific deficit: balance and gait training for post-stroke patients, memory and spatial attention tasks for cognitive impairment, or vestibular desensitisation for balance disorders.
Progress is monitored quantitatively using in-session performance data integrated into clinical records. VR also improves motivation and therapy adherence through an interactive, task-oriented format.

Frequently Asked Questions
- Will VR therapy cause motion sickness?
- Modern medical VR systems are designed to minimise motion sickness with low latency and high frame rates. Our physicians monitor your comfort, especially during the first session.
- Who is a candidate for VR therapy?
- Post-stroke patients, vestibular disorders, nerve injuries, and mild-to-moderate cognitive impairment. Suitability is assessed before commencing the programme.
- Is this a consumer game or medical device?
- We use VR rehabilitation platforms designed specifically for clinical purposes, with standardised protocols and clinical outcome measurements — distinct from commercial entertainment games.
- Can VR therapy be done at home?
- Our current VR therapy is clinic-based to allow direct monitoring. Home-based programmes may be considered for selected patients in the future.
