Where this comes from
In the reference topic that owns this term
Reference topic 21, The Pain You Were Not Supposed to Keep, states the mismatch as a card: what the system evolved to expect, what it gets instead, and what happens in the gap.
Mismatch card
- What it expects
Injury, then a return to use while still sore, among people who help.
- What it gets
Rest, scans that find "damage" in pain-free people, fear and, for a time, freely prescribed opioids.
- What happens in the gap
A sensitized alarm keeps ringing after tissue heals, and ordinary pain hardens into disability.
What that chapter recommends
3 of the 7 graded recommendations in Reference topic 21, strongest evidence first. How the grades work.
When your back first hurts, keep going
StrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.Stay as active as pain allows. Bed rest slowed recovery, and most acute back pain settles within weeks, with or without paracetamol (acetaminophen).
Skip the routine scan
StrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.Without warning signs, imaging does not improve outcomes, and "abnormal" findings are common in pain-free people of every age.
Move as treatment
StrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.Choose exercise you will keep doing. In people recently recovered from back pain, a walking and education program that built up over three months to at least 30 minutes, five times a week, cut relapses (Chapter 2).
