Back braces and neck collars

A back brace wraps around the lower back and belly. It is also called a lumbar support, back belt or corset. Most are made of stretchy fabric, sometimes with firmer panels, and close with straps. Some are custom made.

A neck collar, also called a cervical collar, wraps around the neck. Soft collars are made of foam. Firmer collars are made of plastic and hold the neck more still.

Many braces and collars are sold at pharmacies or online. A clinician, physical therapist or orthotist (a specialist who makes and fits braces) may also fit one.

Other uses

Braces and collars are also used to protect the spine after some injuries, fractures and spine surgeries. Braces are also used to treat scoliosis (a sideways curve of the spine) in children who are still growing. Those are different situations with their own rules, and this page does not cover them. If a surgeon or care team gave you a brace for one of these reasons, follow their instructions.

A brace or collar can limit how far you bend and twist. For some people, this makes painful movements less likely for a while.

A brace can feel supportive and warm, which may make moving feel less scary during a flare.

Researchers are not sure which of these effects matters more.

A brace does not fix the cause of back or neck pain, and it does not strengthen the muscles that support the spine.

Getting fitted

A brace or collar that fits well feels snug but not tight. It does not pinch, rub, or make it hard to breathe or swallow.

When to wear it

Many clinicians suggest wearing a back brace for short periods, such as during activities that tend to bring on pain, rather than all day.

Your care team can tell you how long to use a brace or collar. Many people are asked to cut back gradually rather than stop all at once, and to keep up gentle movement and exercise.

Day to day

Many people wear a thin cotton layer under a back brace to protect the skin and soak up sweat. It helps to take the brace off and check your skin each day, and to keep the skin under it clean and dry.

Low back

Back belts do not seem to prevent low back pain. Large studies of workers found that wearing one did not lower the chance of back pain or back injury. [1] [8] [9]

For people who already have low back pain, the evidence is unclear. Some small studies found a small drop in pain or better function, and others found little or no difference. [1] [10]

A Cochrane review published in 2026 looked at long-lasting low back pain. It found too little evidence to support routine use of lumbar supports, and none of its studies reported on side effects. [2]

A UK guideline for low back pain advises clinicians not to offer belts or corsets. [11]

Many of these studies were small, and people knew whether they were wearing a brace, which makes the results less certain.

Neck

For recent arm pain from an irritated nerve in the neck, one Dutch trial of 205 people found that a semi-hard collar with rest for 3 to 6 weeks eased arm and neck pain somewhat more than waiting it out. Physical therapy with home exercises helped about as much as the collar. [4]

A Canadian neck pain guideline takes a different view. It advises clinicians not to offer collars for recent neck pain, including pain with nerve symptoms, and to focus on exercise and staying active. [3]

After whiplash (a neck strain from a car crash or similar jolt), people who stayed active or started gentle exercise early did as well as, or better than, people who wore a collar. [5] [6] [13] [14]

Common and mild

• Skin irritation, rubbing or pressure marks where the brace or collar presses.
• Sweating and feeling hot under the brace.
• Some people notice stiffness, especially in the neck after a collar has been worn for a while.

Less certain concerns

• Some clinicians worry that wearing a brace all day for weeks or months could weaken the trunk muscles. A review of small studies did not find this over 1 to 6 months, but the evidence was low quality.
• A brace may give a false sense of security. Wearing a back belt has not been shown to make lifting safer.

Other downsides

• Cost. Prices range from low-cost store-bought belts to custom braces that cost much more, and insurance coverage varies.
• Staying active and moving normally is an important part of recovery for most back and neck pain. A brace is meant to support that, not replace it.

When to get help

If a brace or collar you use for pain makes it hard to breathe or swallow, loosen or remove it right away. If you wear a collar after neck surgery or for a fracture, do not take it off on your own, and call 911 if breathing or swallowing becomes hard or your neck is swelling. Call your care team if a brace or collar causes skin sores, blisters, numbness or tingling.
