How to spot it at home
The simplest test is to ask the child to bend forward with both arms hanging and knees straight, then look at their back from behind at eye level. What you are looking for is not a curve in the spine but one side of the back sitting higher than the other.
Other signs visible standing up: one shoulder higher, one shoulder blade more prominent, uneven gaps at the waist, or a body that leans slightly to one side.
The most common adolescent scoliosis is usually painless. That is why it is so often found by accident — swimming, in a photograph, or because clothes stop hanging evenly. If there is prominent pain, that is a reason to have it assessed more thoroughly, not to file it under scoliosis.
The numbers that decide treatment
The size of the curve is measured from an X-ray as the Cobb angle, and that number decides the next step. The American Academy of Family Physicians divides it roughly like this: 10–19 degrees, observation; 20–29 degrees, consider a brace; 30–39 degrees, bracing and/or exercise therapy; 40 degrees and above, referral for surgical assessment. SOSORT does not use a table: its anchors are bracing above 25 degrees during growth, and the observation that above 30 degrees the risk of the curve progressing into adulthood rises. The exact numbers differ between guidelines — the decision still belongs to the spine specialist who examines your child.
The second factor matters just as much: how much growth is left. A 25-degree curve in a child with years of growing ahead is not the same situation as 25 degrees in a teenager who has finished. That is why regular monitoring matters, and why repeat imaging is scheduled by the doctor rather than requested monthly.
Below 30 degrees at skeletal maturity the chance of the curve worsening in adulthood is smaller, which is why that number is often used as a yardstick for the result. The bracing trials themselves used a looser threshold, under 50 degrees. The decision to brace or operate belongs to a doctor, and no exercise program substitutes for it.
Where exercise fits, and where it stops
Scoliosis-specific exercise is not general exercise. It trains awareness of position, breathing directed into the compressed side, and active correction carried into everyday activity.
The evidence is real but should be read for what it is. In a small, non-randomised study of Schroth exercises run alongside bracing, the exercise group improved in 17% of patients and worsened in 21%, against a comparison group that improved in only 4% and worsened in 50%. The most striking part is compliance: among those who did the program as prescribed, 31% improved and the rest stayed stable — none worsened; among those who did not, none improved and 46% worsened.
The honest conclusion: exercise has a role, mostly alongside a brace, and only if it is actually done. It does not "get rid of" scoliosis, does not replace a brace on a curve that needs one, and does not make surgery unnecessary where it is indicated. We work with the treating doctor, not instead of them.
Frequently asked questions
Can exercise straighten my child’s spine?
No, and anyone promising that is going beyond what the studies show. What is realistic is keeping the curve from increasing through the growing years, improving balance and endurance, and making a brace more tolerable if one is worn. In the studies, the most common outcome is stability — and stability, in a child who is still growing, is a good outcome.
My child already wears a brace. Is physiotherapy still needed?
That is exactly where the evidence is strongest. The study cited on this page compared Schroth exercise alongside a brace against bracing alone, and far fewer children worsened in the group that added the exercise. It also helps maintain strength and movement through months of brace wear. What decides it is whether the exercises actually get done — a program nobody follows delivers nothing.
My scoliosis was only found in adulthood. Is there still a point?
The goal shifts, and it is still worth it. In an adult whose growth is finished, the focus is not changing the degree of curve but managing pain if there is any, maintaining strength and endurance, and keeping the ability to do what you want to do. Plenty of adults with mild scoliosis live without meaningful symptoms; the ones who come here usually come for pain or fatigue, and both of those can be worked on.
