What is mirror therapy?

Mirror therapy in one paragraph

Mirror therapy is a technique where a person who has lost a limb watches the reflection of their intact limb in a mirror, positioned so the reflection looks like the missing one. The brain sees what appears to be two whole limbs moving together. It has been used since the mid-1990s to explore phantom limb sensations, the feeling that a missing limb is still there, and phantom limb pain.

Where it came from

The technique was described in a 1996 paper by neuroscientist V.S. Ramachandran and Diane Rogers-Ramachandran. They built a “mirror box” and tested it with ten people who had lost an arm. When the reflection of the intact hand lined up with where the missing hand felt like it was, people reported vivid sensations of movement in the phantom limb, and some found relief from painful clenching spasms. The authors called it a kind of “virtual reality box.” ^[1]

Phantom limb sensations and phantom limb pain

Many people who lose a limb continue to feel it. For some those sensations are neutral, for others they hurt. A 2020 systematic review and meta-analysis pooling 37 studies estimated that about 64% of people with an amputation experience phantom limb pain (95% confidence interval 60–68%), though the authors note most of the underlying studies carried a moderate to high risk of bias. ^[2]

Phantom limb pain is a real, often difficult condition and it is best managed with a qualified healthcare provider. Mirror therapy is one of several approaches people and clinicians have explored.

How a mirror session works

In a classic setup, a mirror is placed between the limbs, or inside a small box, so the person can see the reflection of the intact limb where the missing one would be. They then move the intact limb while watching the reflection, so the brain gets visual feedback that looks like the missing limb moving too.

There is no single standard schedule that applies to everyone. If you want to try it, a physical therapist, prosthetist or pain specialist can help you decide what is appropriate for you.

What the research says

The honest answer is that the evidence is mixed.

• Early results looked promising. A small 2007 trial reported in the New England Journal of Medicine followed 18 people who completed it across three groups (a mirror, a covered mirror, and mental visualization). All six in the mirror group reported less pain, compared with one of six in the covered-mirror group. It was a very small study. ^[3]
• Later, more rigorous reviews were less encouraging. A 2023 systematic review in the European Journal of Pain, limited to randomized placebo-controlled trials, concluded it did not find evidence of efficacy. ^[4]
• The overall picture is unsettled. A 2024 review described the evidence as mixed, pointing to small studies of varying quality and a poorly understood mechanism, while noting that mirror therapy is accessible and considered low-risk. ^[5]

Where virtual reality comes in

A physical mirror has limits: it is fixed in place, it works for one limb at a time, and the reflection only looks right from one angle. Virtual reality can place you inside a full-body avatar and mirror your movements digitally, which opens up setups a physical mirror cannot do.

Research on VR and augmented reality for phantom limb pain is early. A systematic review of nine studies found that all reported pain improvements, but the authors concluded they could not recommend VR or AR for phantom limb pain because most studies lacked randomization, control groups or adequate sample sizes. ^[6]

Where PhantomVR fits

PhantomVR is an in-development app from PhantomTech Labs that brings the mirror therapy idea into virtual reality. You choose your limb and amputation level, and a full-body avatar mirrors your intact side in real time, in an experience designed to feel calm, not clinical.

To be clear about what it is: PhantomVR is a wellness tool, not a medical device. We do not claim it treats, cures or prevents any condition, and we will not make treatment claims we cannot back up. There is no launch date yet. You can sign up for updates or follow the devlog.

Quick answers

Is mirror therapy only for amputees?

No. Mirror-based approaches have also been studied for other conditions, such as stroke rehabilitation. This guide focuses on limb loss.

Can I try it at home?

People do use simple mirror setups at home. Talk with your care team about what is appropriate for you first, especially if you have pain.

Does PhantomVR replace mirror therapy or medical care?

No. It is a wellness tool and is not a substitute for care from a qualified healthcare provider.
