How to check for scoliosis at home, and what it can't tell you

A quick home check can show signs worth showing a doctor, such as uneven shoulders, or one side of the back sitting higher when you bend forward. It can't confirm scoliosis. That needs a standing X-ray, on which a doctor measures the Cobb angle: a curve of 10° or more, with rotation of the spine, is what doctors call scoliosis.

What you need

A helper, good light, and a bare back or a fitted top. Stand barefoot on a level floor.

Standing check

Stand relaxed with your arms by your sides. Your helper looks from behind and from the front for:

• One shoulder higher than the other
• One shoulder blade sticking out more
• A bigger gap between one arm and the waist
• One hip higher, or sticking out more
• Clothes that hang unevenly

Forward bend test

1. Stand with your feet together and your knees straight.
2. Put your palms together and let your arms hang.
3. Bend forward slowly from the hips until your back is level, letting your head drop.
4. Your helper crouches behind you and looks along your back at eye level. Is one side of the ribs or the lower back higher than the other?

Doctors use the same test, often with a small device called a scoliometer that measures how much the trunk is rotated.

What it can't tell you

A home check can't measure a curve, and it can't tell scoliosis apart from other causes of unevenness, such as one leg being slightly longer or tight muscles. A normal-looking check doesn't rule out a small curve, and a visible difference doesn't confirm one.

For teenagers, the US Preventive Services Task Force concluded in 2018 that there isn't enough evidence to weigh the benefits and harms of routine screening. That's about screening everyone; if you notice signs, it still makes sense to get them checked.

When to see a doctor

The NHS advises seeing a GP if you think you or your child has scoliosis. It's unlikely to be anything serious, but an X-ray will show how big any curve is, and your GP can refer you to a specialist if needed.
