How Does a Back Posture Brace Work?

Having good posture can make a person not only look healthier and more confident but become healthier and more confident.

Physicians and therapists often prescribe a back brace during healing from back injuries, in order to limit the motion of the back muscles and the spine.

This is to ensure that healing occurs in the bony structures of the lumbar (lower back and spine), and that torn muscles or ligaments and tendons are not further used. Low back pain may occur during the overuse of a muscle group.

What is a Posture Brace?

Posture braces, also known as “clavicle braces”, are medical devices that assist individuals with poor posture or shoulder slump by providing upper body support, serving as a gentle reminder to not slouch in the process.

A back posture brace works by limiting the muscles from overworking, and also cue the muscles to stay in a particular position that allows for best postural alignment.

Poor posture is usually developed as a result of our actions or inactions that happens on a daily basis. Repetitive actions eventually become habits, and in many cases, bad posture is a result of one’s occupation.

For example, office workers and truck drivers are at higher risk of developing poor posture. The back brace as support is an excellent tool that can assist with getting one’s posture back in order.

Types Of Back Posture Braces

There are a few types of different back posture braces, for various needs. Some are used to reduce the motion of the spine, and some are used for postural re-alignment.

Others are used to give the back muscles some rest during a long workday. The following are varieties of back braces and how the typical back posture brace works.

Rigid braces are known as lumbosacral orthoses because they help treat conditions of the lumbar spine and sacrum.

Rigid braces can be used to treat lower back pain. They are also commonly prescribed to stabilize the lumbar spine after surgery.

Rigid braces work by limiting the motion of the spine. They are form-fitted, plastic braces that are for more severe injuries and during the first and middle phases of healing.

This type of brace need to be properly fitted by a professional in order to optimally eliminate the motion in the spine and can be very helpful for healing fractures, aligning broken bones, healing ligamentous tears, healing after spinal fusion surgeries, and for fixing torn muscles.

The cons with rigid braces are that they can be slightly uncomfortable and can irritate the skin if not properly fitted. Rigid back posture braces are mostly used for serious postural alignment issues and for intense retraining programs. They are not to be casually used while lying down as much.

The most commonly prescribed rigid braces include the: chairback brace, Raney flexion jacket and Williams brace.

Sacroiliac and lumbosacral belts are back braces that treat pain in the lumbar spine and sacrum.

The Sacroiliac and lumbosacral belts are the most commonly seen and used. These belts stabilize the lower back and are made of cotton and lightweight stretchy and firm materials.

Typically these lower back brace belts can adjust pressure through laces or velcro adjustments that are found at the back of the belt, the front of the belt, or at the sides of the belt. The width of the Sacroiliac and lumbosacral belts across the lower back area can range from 15 centimeters to 25 centimeters.

The sacroiliac back posture brace works by preventing motion through compressing the joints between the hips and the sacrum (lower spine), and is very effective, as it gives these muscles a bit of a rest after the abdominal muscles, spinal muscles and core muscles are overworked,

Additional Information

For workplaces where a person may sit or stand for an extended period of time without variations in movement, muscle overuse or awkward postures can often result in lower back pain and postural dysfunction.

Good posture can be retrained with the use of a posture brace, posture support, posture exercises or even posture taping. It follows that without a brace, the abdominal muscles, spinal muscles, and core muscles act as stabilizers for the lower back.

In general, back braces all work through immobilizing the lower back muscles, ligament, and bones of the spine in order to give the lower back a bit of a rest, and allows for any injuries to heal without overstraining the muscles.

Understanding how the back posture brace works and when to use it and when not to use it is very important.

If you are healthy without any severe injuries but choose to use a back posture brace for postural alignment, it is then important to only use it to the just-right duration and amount.

Because using the lumbar support brace too much will cause the muscles to eventually weaken and prompting the back to be more susceptible to injury in the future.

In working on postural alignment and fitness, core muscle exercises and postural alignment exercises are most recommended while using the back posture brace in moderation, for its specific purpose with respect to your individual situation is responsive.

For those that wear the lumbar support for healing, it is important to have the use of the brace monitored by a professional, because, once the bones and ligaments and muscles are properly healed, the person using the brace should slowly rid themselves off of wearing it and start to regain muscle use and strength in the lumbar area.


In general, for preventing slouching at a job where a lot of pressure is put on the lower back, the brace should only be worn during certain times of the workday, and not for the whole workday. This will allow the back muscles to be used to the right amount, and to rest as well.

Finally, this information on work and use of a back posture brace is more general, and a professional should be consulted for best use if you are thinking of using a back brace.
