Low-Profile Design, High-Quality

Enjoy daily activities like walking or sitting. The SI Brace is a low-profile brace that provides compression and helps with pain relief around the sacrum area of the back and stability of the SI joint.

Made with mesh material allows for plenty ventilation to keep cool. Since the SI Brace can be worn underneath clothing, the pulley system in the back allows for the user to tighten or loosen, finding the perfect fit. It also helps reduce strain on ligaments. Hassel-free, the anti-migration strips are to prevent slippage while wearing.

The lacer design compression system is the unique feature of each BOA product. The system utilizes a multiple tear-drop channel design in conjunction with a high-tension harness cord and one simple pull strap to effectively tighten the orthosis with minimal exertion, strength, grasp and body motion by the patient.

Features & Benefits:

Create a personal fit with the lacer compression system, which is a feature of the BOA product. This pulley system lets you adjust the fit, providing complete comfort made for your body that won’t restrict your movement with complete stability
Made with breathable fabric for ventilation and complete comfort
Offers anti-migration strips that prevent the brace from moving around
Available in three sizes, which is based on hip-circumference measurements

I have degenerate bone disease in my spine, scoliosis between L5 and S1 two bulging disks between L5 - L4 and L4 - L3 con-caving in lumber on right side causing constant sciatica affecting my right leg and hip severely making standing, sitting or walking a nightmare. I use ice packs, heat pads, norcos back braces I feel like nothing works was considering trying that leg wrap that applies pressure to back of knee on my sciatic side but fear it will do nothing for all the hip, S1, and lumbar pain. Will this help me at all?
Question by: Cat on Apr 8, 2015, 10:12 PM
The SI belt is for discomfort over the SI joint, not sciatica. Sciatica comes from the lumbar spine so you would need a back brace for the lumbar spine, which it soulds like you have been using.
