Does Bracing Work for Scoliosis? What the BrAIST Study Found.
The BrAIST Study (Bracing in Adolescent Idiopathic Scoliosis Trial) is the gold standard research on whether bracing actually works for Adolescent Idiopathic Scoliosis (AIS). It shows clearly that consistent brace wear lowers the risk of curve progression in growing adolescents.
Bracing plays a major role in AIS treatment, especially for kids and teens who still have significant growth remaining. AIS is scoliosis that appears in adolescents without a known cause. Providers typically recommend bracing for curves between 25 and 45 degrees, since proper brace wear can prevent the curve from worsening and often reduces the need for surgery. There are several types of scoliosis braces available today, and the philosophy behind each one affects how well it holds a curve.
What Is the BrAIST Study?
For years, clinicians debated how many hours a day a patient should wear a brace to get the best results. The BrAIST Study set out to answer that question. Dr. Stuart Weinstein led the trial, published in 2013, to directly measure how well back braces control scoliosis progression.
How the Study Was Designed?
Between 2007 and 2013, researchers enrolled more than 200 adolescents, ages 10 to 15, with AIS and Cobb angles between 20 and 40 degrees. They randomly assigned each participant to one of two groups:
- Bracing group: Patients wore a scoliosis brace 18 hours a day. A built-in sensor tracked real usage time.
- Observation group: Patients did not wear a brace and received no additional scoliosis treatment.
Researchers evaluated each patient at two clear endpoints:
- Treatment success: The patient reached skeletal maturity without their curve reaching 50 degrees.
- Treatment failure: The curve progressed to 50 degrees, which typically triggers surgical consideration.
How Many Hours a Day Should a Scoliosis Brace Be Worn?
The results were clear. The number of hours a brace is worn each day has a major effect on curve progression. Kids who wore the brace at least 18 hours a day had a significantly lower chance of needing surgery than those who wore it less, or those in the observation group.
Interestingly, wearing the brace more than 18 hours a day did not add any extra benefit. Hitting the recommended wear time is what makes the brace effective. Wearing it longer than that doesn’t improve the outcome.
The brace works by applying steady pressure to the curved areas of the spine. That pressure holds the curve in place, can prevent it from worsening, and may even gradually reduce the degree of curvature over time.
What This Means If Your Child Has Been Diagnosed
The BrAIST Study gives us real, strong evidence for how to treat scoliosis with a brace. If your child has been diagnosed, talk to your doctor about the best options for their specific curve and growth stage. Wearing a brace for the recommended amount of time can be an effective way to hold the curve steady and avoid surgery down the road. This matters close to home too. Most of the kids we see in Jacksonville and Ponte Vedra Beach fall right in the 20 to 40 degree range this study covers.
Bracing is one part of the picture. Many families pair brace wear with the Schroth Method to actively strengthen and correct posture alongside the brace, rather than relying on the brace alone.
