Detailed Description

Sacroiliac Belt for SI Joint Pain Relief

This sacroiliac back brace is designed to help stabilize and significantly reduce the motion of the sacroiliac (SI) joints with direct conservative compression. It is made of lightweight and breathable mesh material that is comfortable to wear. The flexible pulley system makes it easy for one to adjust quickly with one hand. The pulley system also allows the patient to customize the amount of compression and pressure that is applied to the lumbar and hip area.

The sacroiliac pelvic belt is included with two comfortable pads that can easily be relocated or removed for optimal comfort. When the pads are removed it can be used to help treat postpartum symphysis pubis dysfunction.

This sacroiliac pain relief brace is indicated to help treat conditions such as SI joint pain and instability, arthritis, symphysis, sciatica pain, and other pelvic pain. It is important to get the correct placement of the belt across the hips and buttocks to relieve SI Joint pain.

The lower back brace is universal and will fit hip circumferences 23"-50". Since the belt is a one size fits all, you may need to fold the left side inward or cut it to fit you more properly.

If you are looking for a slimmer, more narrower design, check out the Cybertech Low Profile Sacroiliac Joint Belt. This sacroiliac brace provides the same compression power with a low profile design. It is also available in two different sizes: Small and Standard.

What is the Sacroiliac Joint?

The sacroiliac joints are formed by the connection between the bone in the lower portion of the spine and the bones that make up the pelvis and connect the spine to the pelvic bone. The ligaments are put under a lot of stress as the sacroiliac supports most of the upper body weight. Damage or torn cartilage can cause these bones to rub together for severe back pain. Pregnancy, gout, and arthritis can also cause inflammation of the SI joints.

SI joint dysfunction is a condition that requires proper lumbar and spine support. The Sacroiliac Belt is a great back and spine support to help alleviate and recover from the back pain caused by SI joint dysfunction and instability. Good posture is also essential to the healing process.

Best device for si joints ive found


This is my 3rd device for widening of my si joints. It is the best by far. I like the adjustbility. I felt relief immediately when i put it on.
Was crushed through the pelvis 20 years sacrum was broken thru on each side where the joint is.. so from time to time one or the other of my hips comes out of socket opposite where the si widens..obviously painful. Sometimes it has been out for months especially due to winter and arthritus. Im 64yrs old...nice to find some comfort
This support is made perfectly for the problem.
Thank you for the relief!

Life is great again!


Thank you very much for quick shipment of my new brace, it arrived yesterday, in five minutes I had it on. I tightened it and for the first time in several years I could straighten up to my normal height of 6' 1''. What a wonderful feeling and the usual pain associated with walking was gone. It feels like an other five years have been added to my 93. Life is great again. Thank you, thank you so much.
