Scoliosis Bracing
Providence Night Brace
A surgeon's overview of the Providence night-time brace — a brace worn only in bed, how it works, and what the evidence shows.
The Providence brace takes a different approach to most scoliosis braces: it is designed to be worn only at night, in bed. As a spinal surgeon I prescribe braces and monitor the spine; the design and fitting are the work of a specialist orthotist. This page explains what the Providence night brace is, how a brace worn for only part of the day can work, and what the evidence tells us.

What the Providence night brace is
The Providence brace is a night-time thoracolumbosacral orthosis. Because it is worn lying down, it can apply a much stronger, over-corrective force than would be tolerable while standing — it pushes and bends the spine well past its standing position for the eight or so hours the patient is asleep. The great practical advantage is obvious: the young person wears nothing during the day, at school or with friends, which removes much of the social and psychological burden that makes full-time bracing so hard.
How it works
The principle is aggressive night-time correction. By over-correcting the curve while the patient sleeps, the brace aims to interrupt the tendency of the curve to progress during growth, even though it is off during the day. In-brace X-rays with the Providence brace typically show very large corrections of the curve. This concept works best for particular curve patterns and sizes, especially single lumbar and thoracolumbar curves, and less well for larger or high thoracic curves.
Who it is for
Night-time bracing is generally considered for growing children with smaller to moderate single curves, often lumbar or thoracolumbar, where the curve pattern lends itself to strong over-correction lying down. The Providence brace is commonly recommended for curves up to around the mid-30-degree range. In patients with larger curves or rapid growth, night-time bracing alone may not be enough. Whether it is appropriate is a specialist decision based on the curve.
What the evidence shows
The evidence for the Providence night brace is encouraging within its indications. Comparative studies have found that, for suitable female patients with mild to moderate curves, the Providence night brace can be as effective as a full-time Boston brace at preventing progression, while being far easier to live with and better for quality of life and adherence. Series report very high in-brace corrections and prevention of significant progression in the majority of well-selected patients. Systematic reviews of night-time bracing broadly support its effectiveness for appropriate curves, with success rates comparable to full-time rigid bracing. The key caveat is patient selection: the benefit depends on curve type, size and skeletal maturity, and for moderate-to-severe curves with high growth velocity, night bracing alone may be insufficient.
What to expect
The brace is custom-made and fitted by a specialist orthotist, with an in-brace X-ray to confirm the correction. It is worn only in bed, reviewed in clinic with periodic X-rays, and continued until skeletal maturity before being withdrawn, with the spine monitored throughout.

Every patient is different, and investigations, treatment options, potential risks, expected recovery and outcomes depend upon an individual's diagnosis, symptoms, medical history, examination findings, skeletal maturity, curve pattern and personal circumstances. A brace should be prescribed and monitored by a specialist team and designed and fitted by a qualified orthotist. Decisions regarding treatment should always be made following consultation with your treating spinal surgeon or healthcare professional.
