What is SI Joint Dysfunction?

The SI joints are located on the sides of the spine, connecting it to the pelvis. They are responsible for stabilizing the pelvis and absorbing the shock of movement. Also called sacroiliac joints, the SI joints are kept in alignment by multiple ligaments.

SI joint dysfunction starts when the ligaments do not provide sufficient support. Some of the conditions that can contribute to this destabilization include arthritis, pregnancy, and abnormally tilted sacrum. People who suffer from SI joint dysfunction often experience SI joint inflammation, lumbar pain, as well as pelvic and leg nerve pain.

Tips for Wearing a SI Belt

  • How to Wear an SI Belt?

    While SI belts are often the first line of treatment of SI joint dysfunction, in order to work they have to be worn correctly. SI support belts should be wrapped around the pelvis, never the lower back. Most SI joint belts come with adjustable fasteners for a personalized level of support and compression. It is crucial that an SI belt is not overly tight or loose, as it can either impede blood circulation or provide insufficient support.

  • What Does an SI Belt do?

    An SI belt is designed to alleviate pain and inflammation by limiting movement of the sacroiliac joint and promoting correct pelvis alignment—a job usually done by the ligaments. SI joint belts also offer compression to increase blood circulation, which can accelerate healing.

  • Can You Exercise With SI Joint Pain?

    Vigorous exercise, such as running, is not recommended for those suffering from sacroiliac dysfunction, as it can exacerbate SI joint pain. Low-impact activities, such as walking, is more gentle on the lower back and pelvis and is a better option for those suffering from SI pain.

  • How Long Does it Take for an SI Joint Injury to Heal?

    The severity of the SI joint injury will greatly impact the length of time it takes to heal. If your SI joint pain is due to a sudden injury, the healing process should take between a few days to a few weeks. Doctors typically recommend that patients suffering from SI joint pain wear an SI belt both day and night for ten days, followed by six to eight weeks of wearing the belt only during the day. Be sure to talk to your doctor, if you have any questions.
