7 Stretches to Soothe Sacroiliac Joint Dysfunction

Rate this post


If you’ve been suffering from chronic lower back pain, there’s about a chance that it is caused by SI joint dysfunction. (1) Here are easy, soothing stretches you can do anywhere to release the pain.

The SI joint – also known as the sacroiliac joint – connects the sacrum to either the right or the left iliac bones, which are the large bones that form your pelvis. These joints support the weight of your entire body when you are upright, help you to balance as you walk, and absorb shock to the spine. For the most part, they are immobile and allow for just a few degrees of rotation.

Women are eight to ten times more likely to have sacroiliac joint pain than men, due to hormonal and structural differences. (2)

Causes of SI Joint Pain


Hormonal changes during pregnancy can loosen vital ligaments, leading to lower back pain. A study showed that 36 percent of women with full-term normal delivery, and 23 percent of women with C-sections, experienced SI joint dysfunction. While the prevalence of SI joint dysfunction is slightly less postpartum (26 percent), the severity is stronger, because new mothers typically ignore their pain while caring for a newborn. (3)

During pregnancy, women typically gain 20-40 lbs which shifts the body’s center of gravity. At the same time, the abdominal muscles stretch, which causes women to lose their ability to maintain proper posture. The hormone relaxin is also released ten times the normal amount to loosen the supporting structures of the SI joint in preparation for birth, which can set the stage for SI joint dysfunction. (4)


As we age, it is possible to develop arthritis and other diseases that cause degeneration of the SI joint which leads to “hypomobility” or lack of mobility in the joint. A study showed that 23 percent of participants experienced degenerative changes over a three year period, 68 percent of them being women. (5)


SI joint dysfunction is also sometimes referred to as “sacroiliac joint instability” or “hypermobility” due to a lack of support from the once-strong ligaments. The weakened, injured, or sprained ligaments can stem from a torsion or high-impact injury, like a hard fall. (6) Over half of patients diagnosed with SI joint pain had some sort of traumatic injury.

Abnormal Gait

Some people are born with abnormal gait qualities, like lumbar lordosis or a pelvic tilt, that can lead to SI joint dysfunction, but modern day societal habits such as wearing high heels and constant sitting are the cause of most issues today. We naturally have a small degree of anterior pelvic tilt and lumbar lordosis for proper shock absorption in the spine, but both high heels and sitting can lead to an unhealthy amount of both of these. (8) As they increase, there is increased compression in the SI joint that can lead to pain and dysfunction.

Relieve Lower Back Pain with These 7 Stretches

Specific stretches and exercises have been shown to improve and even eliminate SI joint pain and injury by increasing flexibility, balance, stretch, and stability. (9) Practice this sequence once to twice a day for maximum results. All you need is a mat, a yoga block or pillow, and a wall.

  5. Repeat 5x on each side.

Bridge | 30 sec


This stretch relieves tension in the hip flexors while strengthening the muscles around the SI joint like the glutes, outer hips, and lower back.

This stretch relieves tension in the glutes, hips, and lower back to release tightness in the SI joint.

  1. Start in a seated position. Bend your left knee in towards your body, then bend your right knee and place it over your left knee.
  2. Try to have your knees perfectly stacked, one on top of the other, and keep your feet flexed to protect your knees. Both of your sit bones should be pressing into the ground. If this is not possible, then prop your hips up onto a yoga block or pillow to allow equal weight on both sit bones.

TFL Wall Stretch | 30 sec per side


The Tensor Fascia Latae (TFL) is a muscle of the outer thigh that attaches to the IT band and acts as a hip stabilizer, assisting in keeping the balance of the pelvis while standing, walking, or running. (10) When tight, it can cause a pelvic shift, leading to SI joint pain.

  1. Stand slightly more than an arm’s distance from a wall, with your right side facing it.
