Why twenty two years of research on imagining movement for back pain still says maybe

In 2004 a physiotherapist in Brisbane sat thirteen people down with a stack of photographs of hands and asked them to say, as fast as they could, whether each hand was a left or a right. Nobody moved the painful limb. Six weeks later the group's pain had fallen by roughly twenty five points on a neuropathic pain scale, and the number needed to treat for a fifty percent reduction was about two (Pain, 2004).

Twenty two years on, a systematic review and meta-analysis published this month asked whether that same family of techniques does anything for ordinary chronic back and neck pain. Not phantom limbs. Not complex regional pain syndrome. The everyday kind, where the scan says very little and the pain stays anyway.

The team, working out of Acibadem Mehmet Ali Aydinlar University in Istanbul, pooled nine studies covering 411 participants (Medicina, 2026). Eight of those studies, with 337 participants between them, fed the meta-analysis proper. Movement representation techniques, the umbrella term for motor imagery, mirror therapy and watching someone else move, produced a large pooled effect on pain intensity, with a Hedges' g of 1.63 favouring the imagery groups, and a moderate effect on disability at 0.64. Fear of movement shifted a long way too, though not far enough to clear statistical significance.

Then comes the sentence that matters most, and it belongs to the authors: the certainty of the evidence was very low for all three outcomes. Every pooled trial was judged at high risk of bias or raised concerns. Heterogeneity was substantial. They call their own estimates exploratory and say plainly that these numbers do not support firm clinical recommendations.

So here is the arc. 2004: thirteen people, photographs of hands, a large effect. 2006: fifty one people with phantom limb pain or complex regional pain syndrome, pain falling 23.4 mm against 10.5 mm in the comparison group, and the gains still measurable six months later (Neurology, 2006). Earlier in 2026: a scoping review of nineteen studies asking whether imagining movement steadies balance in older adults, which we wrote about in July, and which came back genuinely mixed. And now the spine, with large effects sitting on very low certainty.

Twenty two years. Four different populations. The direction has not wobbled once. The quality of the evidence behind it has barely improved.

That combination is unusual enough to sit with for a moment. Most ideas in rehabilitation either firm up or quietly fall apart inside a decade. This one has done neither, and I think there is a structural reason rather than a lazy one: you cannot blind a person to whether they were asked to picture a movement in their mind. They know. And once they know, expectation is inside the measurement, tangled up with whatever the imagery is genuinely doing to the brain's map of the body, which means the trials stay small, the blinding stays impossible, the risk of bias stays high, and a pooled effect of 1.63 sits there looking far too good in exactly the way small trial effects tend to look right before bigger trials cut them down to size. We watched precisely that happen to strength training for fibromyalgia two weeks ago.

Here is the part I find hard to be neutral about. Imagined movement is not a research discovery in the Feldenkrais Method®. It is furniture. Moshe Feldenkrais was building it into lessons decades before anyone laid out laterality cards in a clinic, and in an Awareness Through Movement® lesson you will regularly be asked to stop moving altogether, picture the movement in fine detail several times, and only then do it again for real.

A woman in her sixties told me last Tuesday, right after the imagining section of a lesson, that she was certain nothing would happen because she is "not a visual person". Her turn to the left then arrived about a hand's width further than it had five minutes earlier. She laughed. She also asked, quite reasonably, whether it would still be there in the morning. I told her I did not know.

What I would take from the arc is narrow, and I want to keep it narrow. Imagery is not a replacement for moving; it is what remains available when moving is the problem. The bad week after a flare. The ten minutes before you have to get out of the car. The stretch of recovery where every real attempt is negotiated against a body that has stopped believing you. It carries no load, it costs nothing, and on the current evidence the honest worst case is that it does rather less than these trials suggest. It sits alongside what your physiotherapist gave you rather than standing in for it. And there is a useful middle step between picturing a movement and doing it fully, which is doing it very small, small enough that it stays easy and comfortable throughout; our guide to micro movements explains why shrinking a movement makes it so much easier to feel. If you want the background, our Feldypedia entries on proprioception decline with age and chronic lower back pain cover the territory this review was working in.

What I keep turning over is the kinesiophobia number. Fear of movement moved a long way in these trials and then failed to clear the significance bar, which the statistics call a null result, and which, sitting in a room with someone who has stopped trusting her own back, does not feel like nothing at all.
