Fear of needles and procedural pain: virtual reality's best-proven use

Of all the applications of virtual reality in healthcare, one gathers particularly strong evidence: distraction during painful procedures. Injections, catheter placement, dressing changes, burn care — short but intense moments, often made worse by fear of needles. This is exactly the ground where virtual reality shows some of its best results.

The mechanism: attention is a limited resource

Pain needs attention to become conscious suffering. And attention is finite. Immersive virtual reality engages vision and hearing at once, carrying the person into a captivating environment and removing them entirely from the procedure room. With less available "bandwidth," the brain processes less pain — and less fear. This is what is called distraction analgesia.

In the specific case of needle fear, there is a double benefit: it reduces pain and the anticipatory anxiety, which is often the hardest part.

What the clinical trials say

This is one of the most studied areas of VR in healthcare, with consistent evidence:

• A meta-analysis that gathered 21 trials concluded that the virtual reality group had a significant reduction in worst-pain intensity, in discomfort, and in time spent thinking about pain, with an increase in the "fun" component of the experience.
• Randomized controlled trials in children with burns — among the most painful procedures there are — showed reductions in pain during care using VR distraction.
• Immersive distraction is particularly valuable because procedural pain is often intense and undertreated, and analgesics are not always enough or desirable.

Few applications of virtual reality in healthcare have an evidence base as consistent as distraction during painful procedures.

Why it matters, beyond the pain

• Less associated trauma — repeated painful experiences, especially in children, can create lasting fear of healthcare. Making the moment more tolerable has long-term value.
• Easier procedures — a calmer, stiller person makes the team's work easier.
• A non-pharmacological alternative — useful when reducing additional medication is the goal.

The role of RVer

RVer is an immersive virtual reality therapy system designed for healthcare environments and certified as a Class I Medical Device by Infarmed, in compliance with the European regulation MDR 2017/745. It is built precisely for this kind of moment: simple for the team to start, comfortable for the patient, and with no collection of patient clinical data.

When the evidence is strong and the use is simple, the value is direct: making a difficult moment — an injection, a dressing change — more tolerable for the person living it.
