Back pain is the leading cause of disability in the world. Nearly four people in ten will have a serious episode at some point. And in the vast majority of cases, it settles by itself within a few weeks.
The real issue is the minority of cases that persist. Those cases are roughly one in five — and close to 80% of what back pain costs society. And it’s exactly in that situation that two very common reflexes, getting a scan and resting, are the least effective.
“My scan shows worn discs”
That sentence worries a great many people. It deserves to be put in perspective.
Most of what shows up on a back scan after 40 — narrowed discs, dried-out discs, small bony growths, worn joints — is also found, in abundance, in people who have never had back pain in their lives. These are marks of time, like grey hair.
That’s why international guidelines advise against scanning routinely when there are no warning signs. Not to save money: because an image isn’t enough to explain pain, and because an alarming-sounding report makes people move less — which perpetuates the very problem you were trying to solve.
There’s a term you may hear: “non-specific” back pain. It sounds like an admission of defeat, but it isn’t one. It means the pain doesn’t boil down to one broken part you could point at, and so treatment should target what your back is able to do, rather than an image.
One important exception: scans are essential in certain situations. A fall or an accident, fever, unexplained weight loss, weakness or numbness that’s getting worse in a leg, trouble controlling your bladder or bowels, or a history of cancer. In those cases, see a doctor promptly.
Should you rest?
No. This is one of the best-established points in the field.
An enormous independent review published in March 2025 pulled together 31 scientific reviews, covering 644 studies and over 97,000 adults. Its conclusion is clear: advice to stay active leads to better outcomes than advice to stay in bed.
For back pain that persists, the same review shows exercise programs reduce pain and improve your ability to move, compared with usual care. Approaches combining several methods also help. Traction, on the other hand, does no better than sham traction.
The cycle you have to break
The mechanism is simple and formidably effective.
You’re in pain, so you avoid certain movements. Because you avoid them, your muscles work less. They lose strength and stamina. Your back therefore copes less well with everyday demands. Things that used to be no trouble start to hurt. And that pain pushes you to avoid even more.
This is called deconditioning. It isn’t what triggered your back pain in the first place. But it’s very often what keeps it from going away. And that’s good news: unlike a worn disc, deconditioning can be reversed.
What kind of exercise, specifically?
A large analysis compared the different methods against each other, drawing on 89 studies and more than 5,500 patients. Here’s what came out:
- for pain: Pilates, control and stability work, and endurance activity (walking, cycling, swimming);
- for improving everyday function: strengthening against resistance;
- for mood, which matters more than people admit when back pain drags on: strengthening and endurance;
- stretching on its own did no better than doing nothing;
- and, often surprising: treatments where the therapist works on you while you stay passive were among the least effective.
The honest takeaway: no method crushes the others, and the benefits are real but moderate. What matters most isn’t which one you pick. It’s that it’s active, that it builds up gradually, and that you keep it going. The best method is, to a large extent, the one you’ll actually do.
Why measuring changes things
When back pain lasts, pain is a poor guide to progress. It shifts with sleep, stress, tiredness, and the week you’ve just had. Judging your progress by pain alone can give a misleading picture of how you’re improving—and often leads to abandoning a program that was, in fact, working.
A number changes that conversation. Measuring your strength at the start, then measuring again a few weeks later, lets you tell the difference between a bad week and a lack of progress.
For many people, that’s also what makes the effort bearable: seeing in black and white that your functional capacity is improving, even if the pain hasn’t fully subsided yet.
Is it sensible to exercise a painful back?
It’s the most common worry, and the answer comes down to one word: dosage.
The problem with a painful back is that you often swing between two extremes: doing nothing or doing too much and paying for it for three days. On machines built for the spine, movement can be limited to the range where you have no pain, and lthe load can be increased gradually. Your back works while staying in a comfortable zone, and the intensity can be increased as your capacity returns.
Getting assessed at Dr.E in Pully
Our centre is medically supervised by Dr Santiago Echeverri, FMH orthopaedic surgeon. The pathway starts with a measurement of your strength and mobility, continues with progressive strengthening, and ends with a re-measurement. We treat mechanical back and neck pain, without pain radiating down the leg.
Treatment is covered by health insurance with a physiotherapy prescription from your family doctor or specialist. Get in touch for an assessment.
Frequently asked questions
Do I need an MRI if I’ve had back pain for a long time?
Not routinely. Without warning signs, guidelines advise against it: most of the wear that shows up is age-related and is found in people without pain too. A scan does become necessary if there’s weakness in a leg, an accident, or other warning signs.
Should I lie down when my back hurts?
No. Staying active gives better results than staying in bed. Temporarily adapting what you do, yes; immobilising yourself, no.
What’s the best exercise for back pain?
None really stands out. Pilates, stability work and endurance appear most effective for reducing pain; strengthening appears most effective for improving everyday function. Stretching alone and passive treatments are among the least effective. Consistency matters more than which method you choose.
How long before I feel something?
Expect eight to twelve weeks. Often functional capacity improves before pain really decreases — that’s normal, and it’s a good sig
When should I see someone without delay?
After a fall or accident, with fever, unexplained weight loss, weakness or numbness getting worse in a leg, trouble controlling your bladder or bowels, or if you have a history of cancer.
