The term "virtual reality" makes many people think of video games or entertainment. In healthcare, the concept is different, and it is important to start there. Virtual reality for clinical use is a clinical tool, not a pastime. This guide explains what it is, how it works and where it applies.
What it actually is
Virtual reality for clinical use is the use of immersive virtual reality environments as a complementary tool in healthcare. The patient wears a headset that transports them into a virtual environment (a calm beach, a forest, a guided scene) with a concrete clinical goal: helping to manage pain and anxiety, stimulating cognition, supporting rehabilitation or inducing relaxation.
What sets it apart from entertainment is not the technology, it is the purpose and the framing: applied with a therapeutic goal, under the supervision of healthcare professionals, integrated into a care plan.
How it works
The mechanism relies on how the brain responds to an engaging sensory experience:
- Attention capture: immersion occupies the senses and shifts focus away from pain or fear. This is the principle of therapeutic distraction.
- Emotional regulation: calm environments and guided breathing techniques help lower activation and anxiety.
- Active stimulation: guided tasks and movements can support cognitive and motor functions in rehabilitation (in RVer, these are modules in development, outside the Class I registration).
Immersion does not "trick" the patient: it creates an experience engaging enough to change what the brain focuses on.
Where it applies in healthcare
The range is broad and growing as evidence accumulates:
- Pain management during procedures (dressings, punctures, wound care).
- Anxiety pre-operative, in oncology, in haemodialysis, in imaging.
- Paediatrics: distraction from fear and pain in children (in RVer's case, from age 10).
- Geriatrics and dementia: cognitive stimulation, reminiscence, calm.
- Rehabilitation motor and neurological.
- Mental health: relaxation, stress management, phobias.
- Palliative care: comfort and escape.
What it is NOT
Worth being explicit to avoid misunderstandings:
- It is not a video game: the goal is clinical, not recreational.
- It does not replace treatment: it is complementary, never an alternative to medical care.
- It decides nothing on its own: any use and any clinical decision rest with the healthcare team.
Important note: virtual reality for clinical use is a complementary and non-pharmacological approach, used under the supervision of healthcare professionals and integrated into the care plan. It does not replace diagnosis, medication or clinical decision.
The role of RVer
RVer is a virtual reality system designed for healthcare environments and registered as a Class I Medical Device (base product) in EUDAMED and with INFARMED (Portugal), bearing the CE mark under MDR 2017/745. It brings together a content library designed for clinical use, is simple for teams to operate, works with content stored on the device itself, without depending on internet, and collects no patient clinical data.
Understanding what virtual reality for clinical use is marks the first step to using it well: as a clinical tool serving the team, not as a gadget. The next step depends on where you are: the Portuguese picture in clinical virtual reality in Portugal, the checklist for choosing a solution, and use in each setting in Solutions.
Frequently asked questions
What is virtual reality for clinical use?
It is the use of immersive virtual reality environments as a complementary tool in healthcare: for pain distraction, anxiety management, cognitive stimulation, rehabilitation or relaxation. It differs from entertainment by being applied with a clinical goal, under the supervision of healthcare professionals and integrated into a care plan.
How does virtual reality for clinical use work?
The patient wears a headset that places them in an immersive virtual environment. That engagement captures attention and alters perception: for example, shifting focus away from pain or fear, inducing relaxation, or stimulating cognitive and motor functions through guided tasks. The effect relies on how the brain responds to an engaging sensory experience.
Does virtual reality for clinical use replace medical treatment?
No. It is a complementary, non-pharmacological approach, used in addition to clinical care and always under the supervision of the healthcare team. It does not replace diagnosis, medication or any clinical decision.
Where is virtual reality used in healthcare?
In varied settings: pain management during procedures, pre-operative anxiety, oncology, haemodialysis, paediatrics, geriatrics and dementia, motor rehabilitation, mental health and palliative care, among others. The specific use always depends on the clinical team's assessment.
