Pain management in hospital settings has long relied on pharmacological approaches. They are effective, but they carry known limitations: side effects, the risk of tolerance, and situations where additional medication is undesirable. This is why interest is growing in non-pharmacological alternatives that can complement the clinical plan, and virtual reality (VR) is one of the most promising.
The mechanism: attention is a limited resource
Pain perception is not a purely mechanical process. The brain has to attend to the pain signal for it to translate into conscious suffering. Attention, however, is finite.
Immersive virtual reality engages several senses at once: vision, hearing, and often the sense of presence in a different space. By drawing the patient into a captivating environment, it reduces the attentional capacity available to process the painful stimulus. This is what the literature describes as distraction analgesia.
The more immersive the experience, the greater the distraction effect tends to be, because the brain has less free "bandwidth" for pain.
Why VR differs from other distractions
Watching television or listening to music also distract, but passively and partially. VR stands out for three reasons:
- Multisensory immersion: the field of view is fully replaced, removing the stimuli of the clinical room.
- Interactivity: the patient can look around and sometimes interact, which deepens engagement.
- Sense of presence: the feeling of "being somewhere else" mobilises cognitive resources more completely.
Relevant clinical contexts
VR for clinical use has applications at various points in the patient journey:
- Short painful procedures (dressing changes, punctures, minor interventions), in hospitals and clinics.
- Rehabilitation, where immersion can make repetitive exercises more tolerable.
- Palliative care and the management of discomfort and associated anxiety.
- Waiting periods, where patient comfort shapes the overall experience.
Important note: VR for clinical use is a complementary approach. It does not replace assessment, diagnosis, or prescription by healthcare professionals, and is always used under their supervision and integrated into the defined clinical plan.
In palliative care, physical pain is only one of the four components of total pain.
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 is built to be simple for clinical teams to use and comfortable for the patient, with no collection of patient clinical data.
The goal is not to promise miracles, but to offer a tool registered as a medical device that helps make the care experience more human, calm, and tolerable.
Frequently asked questions
How does virtual reality help manage pain?
Virtual reality captures the patient's attention in an immersive environment, reducing the attentional capacity available to process the painful stimulus. This distraction analgesia effect can help lower perceived discomfort during procedures or pain states.
Does VR replace pain medication?
No. VR for clinical use is a complementary, non-pharmacological approach. It is used alongside the clinical plan defined by healthcare professionals, never as a substitute for medical assessment or prescription.
In which clinical contexts can it be used?
It is applicable in contexts such as short painful procedures, rehabilitation, palliative care, and managing discomfort during waiting periods, always under the supervision of healthcare professionals.
