How It Works
The sacroiliac joint plays a critical role in transferring weight between your upper body and lower limbs. When inflamed or unstable, this joint can cause pain in the lower back, buttocks, or hips.
The DeRoyal SI Belt compresses and supports this joint, limiting painful micro-movements while reducing ligament strain. The result is improved alignment, better posture, and less pain during standing, walking, or lifting.
Indications:
The DeRoyal SI Support Belt is ideal for:
- Sacroiliac joint pain
- SI joint instability
- Sacroiliac ligament strain
- Postpartum pelvic pain (SI-related)
- Non-surgical support for SI dysfunction
