VR for chronic pain: changing how your body feels

Before your appointment

If you are a Veteran whose pain has changed how you approach everyday activities, the distinction matters. Feeling more comfortable in your body would be valuable. So would being able to carry groceries, spend time with family, or return to a hobby with more confidence. A useful treatment needs to be judged against those goals, as well as pain scores.

What does “sense of self” mean in VR?

Here, sense of self means the experience of inhabiting and moving your body. It includes body ownership, the feeling that a body belongs to you, and agency, the feeling that you are directing its actions. It also includes your impression of what that body can do.

In an immersive headset, a virtual body can move with you and appear where you expect your body to be. That coordination can make an avatar feel like part of you. Researchers call this virtual embodiment. The Malleable Embodiment research project explores how changing the avatar's movement can alter the experience of the body.

This is a focused meaning of self. The experiments do not demonstrate a change to someone's personality, personal history, or identity as a Veteran.

What the talk actually shows

In his 2017 CHI presentation, researcher Shunichi Kasahara describes a system that tracks a person's movements and displays a virtual body through a headset. The team adjusted the displayed movement so that it represented an estimated earlier or later body position.

During a workshop, small forward shifts could make participants describe their bodies as lighter or more energetic. Small backward shifts could make them feel heavier or more sluggish. Larger changes could break the feeling that the avatar was their own body. The demonstration suggests that visual feedback can affect bodily experience, even though the person's actual body weight has not changed.

There are limits to that finding. This was an embodiment experiment, not a chronic pain treatment trial. The system also had a display delay, complicating the explanation of the effects. The published paper calls for further work to establish the mechanism. The talk does not show that this technique produces lasting recovery from pain.

Why this could matter when pain changes how you see yourself

Perhaps you now think twice before reaching overhead, turning your back, or accepting an invitation that involves walking. You may have good reasons for those decisions. The question for care is whether there are ways to expand what feels manageable within your physical limits.

Embodiment research offers one possible route: give a person a different experience of their body, then investigate whether that experience helps with rehabilitation. A virtual body might feel more capable or less vulnerable during a session. The next step is to establish whether that change helps someone do something meaningful afterward.

A small trial makes this distinction especially clear. Researchers randomly assigned 30 people with chronic low back pain to embody either a superhero avatar or a neutral avatar. The superhero group reported improvements in body image during and immediately after the session. Pain, strength, and fear of movement did not improve, and the measured effects were not sustained at one week. The pilot trial supports a temporary change in self-perception, while leaving the question of clinical benefit open.

That result also means feeling more capable in VR should not be treated as evidence that an injury has healed or that a movement restriction no longer applies.

Does changing body ownership reduce chronic pain?

Some studies suggest it can affect pain in specific circumstances. In research involving 20 people with spinal cord injury and 20 healthy comparison participants, virtual leg and full-body illusions were associated with mild pain relief. The effects differed by the illusion and how sensory feedback was coordinated. The spinal cord injury study supports further investigation, rather than a conclusion that embodiment works for every pain condition.

Back pain, pain after spinal cord injury, and phantom limb pain need their own evidence. These studies also do not establish how well the same techniques work in Veterans specifically.

Is all virtual reality pain management based on embodiment?

No. A VR program can teach breathing, relaxation, attention, or other pain management skills without giving you an altered virtual body. For example, the FDA review of EaseVRx describes a prescription behavioral therapy program for adults with chronic low back pain.

Evidence for that program does not prove that the movement manipulation in Kasahara's talk treats chronic pain. When considering VR, ask which program is being offered, what it actually does, and which outcomes its own studies measured.

Questions Veterans can bring to their care team

• Does this program use a virtual body, guided movement, pain management skills, or a combination?
• Has this exact approach been studied for my condition? Were improvements measured after the headset came off?
• What everyday goal would we track alongside pain, such as dressing, walking, or participating in a hobby?
• How would sessions fit my movement limits, balance, vision, and comfort with a headset?
• Who should I contact if symptoms worsen, and how will we decide whether to continue?
• What referral, equipment, and payment arrangements would apply through my VA or community care team?

Ask about the device's safety instructions before starting. The FDA-reviewed EaseVRx instructions, for example, advise stopping for motion sickness, dizziness, headache, or eye strain and resuming according to a doctor's advice. Other programs may have different requirements. Tell your clinician about relevant symptoms and conditions so they can assess suitability.

You can use Valor's chronic pain care guide to organize the broader conversation, or the VA Community Care guide to prepare questions about access. Neither a headset nor a research finding determines your eligibility or coverage.

A more useful goal than “becoming a new person”

The possibility here is specific: VR may offer a way to experience your body differently, even briefly. Researchers are still working out when that experience translates into better function or less pain outside VR.

For a Veteran considering treatment, the practical question is whether a particular program can help with something you want to do. Ask Valor about available home-based chronic pain support, then review the program and its evidence with your treating clinician. The experiments discussed here should not be read as claims about features or outcomes of a particular Valor program.
