If the pain system can learn to be oversensitive, it can learn to be less so. That learning doesn't happen passively. It takes specific inputs — the right kind of movement, the right understanding, and the right approach. Here's what the evidence says actually works.
“Retraining the pain system requires movement, education, and reducing perceived threat — passive treatment alone won't get you there.”
Pain neuroscience education: changing the understanding
The strongest evidence for retraining the pain system starts with education. Teaching patients the biology of how pain works — what's called pain neuroscience education (PNE) — consistently reduces pain, improves function, and lowers disability.
A 2016 systematic review by Louw and colleagues examined 13 randomised controlled trials and found PNE effective for reducing pain intensity, improving physical performance, reducing fear of movement, and decreasing healthcare utilisation in people with chronic musculoskeletal pain.
Why does it work? Because understanding pain changes the perceived threat level. When someone shifts from "my back is crumbling" to "my nervous system is overprotective and I can change that," the DIMs in the system drop — and the brain has less reason to produce high-intensity pain.
Graded exposure: movement as a safety signal
Fear of movement is one of the strongest predictors of ongoing disability after a pain episode. The fear-avoidance model, described by Vlaeyen and Linton, explains how avoiding painful movements makes the pain system more sensitive over time — not less.
Graded exposure is the clinical tool for this. It involves systematically reintroducing feared or avoided movements in a controlled, supported way. The goal isn't to push through pain recklessly. It's to give the nervous system evidence that movement is safe — to add SIMs at a rate the system can handle.
Each successful exposure sends a signal to the brain: this isn't dangerous. Over time, the threat-detection threshold for that movement rises, and pain falls.
Active beats passive
Passive treatments — things done to you — have a role in acute pain management. But for persistent pain, the most important treatments are things you do yourself: movement, education, gradually increasing activity, and learning to interpret pain differently.
Passive treatments can't train the brain to feel safe during movement. Only movement does that. This is why the evidence consistently favours active approaches for long-term outcomes in persistent pain.
Bioplasticity: the brain can change
Just as neuroplasticity can wire a nervous system into pain sensitivity, it can wire it back out. Bioplasticity — the brain's capacity to reorganise toward healthy function — is at the core of pain rehabilitation.
The ingredients are graded, successful movement; understanding that removes threat; sleep that restores the brain's regulatory capacity; social support that adds SIMs; and time. There's no shortcut, but there is a clear mechanism — and that mechanism is genuinely hopeful.
