Chronic pain is not simply acute pain that has gone on too long. It is a distinct phenomenon, in which the nervous system stays on alert even after the original injury has healed: a process sometimes described as central sensitisation. So the tools that help with acute pain do not always apply the same way. Virtual reality is one of those being studied in this more complex context too.
Acute vs. chronic pain: why the mechanism changes
In acute pain (a dressing change, a puncture) virtual reality works mainly through immediate distraction: it occupies attention during the procedure and reduces perceived pain in that moment.
In chronic pain, the goal is broader. It is not about getting through a moment, but about living better with a long-term condition. Here VR combines several elements:
- Distraction and relaxation, to lower tension and hypervigilance to pain.
- Physiological regulation, sometimes through biofeedback: the patient sees and learns to influence signals such as breathing or heart-rate variability.
- Reducing the impact on daily life, more than eliminating the pain itself.
What the clinical trials say
The research is recent but encouraging, especially in two heavily searched conditions:
- Fibromyalgia: a randomized controlled trial published in ACR Open Rheumatology (2025) tested immersive virtual reality combined with multisensor biofeedback. The treatment group had significantly lower pain (P = 0.011) and improvement on the fibromyalgia impact questionnaire (P = 0.018), alongside physiological improvements (heart-rate variability, respiratory rate, skin conductance) and high satisfaction, with no safety concerns.
- Chronic low-back pain: a systematic review with meta-analysis concluded that virtual reality–based rehabilitation is associated with a significant reduction in pain in people with low-back pain.
The pattern is consistent: virtual reality, especially combined with relaxation and biofeedback, can reduce chronic pain intensity and its impact, as part of a broader approach.
The limits it is honest to mention
- Many studies are still pilot trials, with small samples; larger trials are lacking.
- The effect tends to be small to moderate and varies between people and conditions.
- Chronic pain requires a multidisciplinary approach; VR is a complement, not the centre of treatment.
Important note: virtual reality is a complementary, non-pharmacological approach. Chronic pain should be assessed and managed by healthcare professionals, within a multidisciplinary plan. This article is informational and does not constitute clinical advice.
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 works through immersion, relaxation, and comfort: simple for teams to use and with no collection of patient clinical data.
In chronic pain, the honest promise is not "ending the pain," but offering a validated tool that helps reduce its weight on daily life, always integrated into the plan defined by healthcare professionals.

Frequently asked questions
Does virtual reality help with chronic pain?
The evidence points that way. Clinical trials in conditions such as fibromyalgia and chronic low-back pain have associated virtual reality, often combined with biofeedback, with significant reductions in pain intensity and daily-life impact. It is a promising area, still consolidating, used as a complement to the clinical plan.
What is the difference between VR for acute and chronic pain?
In acute pain, VR works mainly through immediate distraction during a procedure. In chronic pain, the focus broadens: beyond distraction, it aims at relaxation, physiological regulation (for example through biofeedback), and reducing the impact of pain on quality of life over time.
Does virtual reality replace chronic pain treatment?
No. Chronic pain requires a multidisciplinary approach defined by healthcare professionals. Virtual reality is a complementary, non-pharmacological tool, integrated into that plan: never a substitute for assessment, medication, or clinical follow-up.
