A quick look at some of the best back support belts

A back support belt is a belt that a person wears to provide support to the lower back or “lumbar” region.

Back support belts are usually adjustable, lightweight, and comfortable to wear. Some feature added compression for additional support, though these types may limit a person’s movement.

Some potential advantages of back support belts include:

  • limiting movement, which may reduce the risk of additional injury and promote healing
  • providing extra lumbar support
  • alleviating pain
  • improving posture

Some potential disadvantages of back support belts include:

  • increased risk of skin irritation and lesions if a person wears the belt incorrectly
  • inappropriate level of support if the belt is too tight or does not fit properly

A 2018 study investigated the effectiveness of a back brace among 22 female participants with chronic back pain.

Back support belts may also help with the following conditions:

Additionally, a 2019 study suggests that back braces may be useful for older patients undergoing a colonoscopy. The researchers note that the device compresses the abdomen in a way that aids insertion of a colonoscope. This may help to reduce both the difficulty and duration of the procedure.

An individual should seek advice from a doctor if their back pain does not go away after a few weeks, becomes severe, or interrupts their daily activities.

People should seek emergency medical advice if any of the following symptoms accompany their back pain:

Below are some answers to frequently asked questions about back support belts.

Do lumbar supports work?

Research into lumbar supports yields mixed results.

A 2019 study investigated the effects of flexible lumbar supports on lower back pain in assembly-line workers. It found no significant difference in reported pain measures between participants in the experimental group versus the placebo group.

However, a separate 2019 study suggests that wearing flexible lumbar support may slightly decrease back pain. The study authors found that participants who wore an abdominal belt reported less pain after 1 week compared with participants who did not wear the belt.

How can a person choose the right back support?

The back support a person requires depends on various factors, including:

  • the type of back condition or back pain they have
  • the tissues involved, which may include bones, muscles, or tendons
  • the location of the pain

People need to consider whether they need lower, middle, or upper back support, and whether the affected tissues may also benefit from heat or cold therapy.

People who need to wear the back support for a long period of time should purchase a product made from lightweight and breathable materials. Doing so will help reduce skin irritation.

Are there alternative options to back support belts?

Some alternatives to back support belts include back braces and back support cushions, both of which may help alleviate lower back pain.

Alternatively, people may use a hot or cold compress to soothe back pain and sore muscles.

If a person’s back pain does not go away by itself, they should contact a doctor, who may recommend physical therapy and back exercises.

How does a back support belt work?

Back support belts are marketed as products that a person can use to:

  • support the tissues of the lower back
  • limit range of motion to aid healing and help prevent additional injury
  • align the back to promote healthy movement and posture
  • alleviate back pain

Are back support belts good for you?

Research on the effectiveness of a back support belt is limited. Some studies suggest that back support belts can help reduce back pain. Other studies have not found any evidence that using a back support belt has any measurable benefits. However, anecdotal reports suggest that these belts help people.

Excessive use of a back support belt can reduce muscle strength in the trunk, which could make a person’s back pain worse.

Can a back brace cause constipation?

Some people who use back braces complain of digestive problems caused by pressure on their abdomens. For others, using a back brace improves their alignment and supports healthy bowel movements.

The key is for people to avoid wearing a back brace so often that the stomach and back muscles weaken, which could make constipation more likely.

When should I wear a back support belt?

A back support belt is not designed for long-term or all-day use. A person who wears a back support belt too frequently can actually weaken their core muscles, or cause them to atrophy, which could worsen their back problems. Spending too much time in a back support belt can irritate the skin, causing chafing or sores.

It can be helpful to wear a back support belt when doing strenuous activities or anything a person knows might make their back hurt. It is best to limit use of a back support belt to a few hours a day, for a few days, or under the guidance of a physician.

Back support belts provide lumbar support and may reduce lower back pain associated with various conditions, including muscle strains and sprains, osteoarthritis, and herniated disks.

There are several back support belts available to purchase online, and some of these have additional features at extra cost.

Anyone who experiences continuing or worsening back pain should contact their doctor, who may be able to provide a diagnosis or offer other treatments.
