Lower back pain can be frustrating and debilitating, and one lesser-known culprit is sacroiliac (SI) joint dysfunction. This condition is often overlooked but can have a significant impact on your mobility and daily activities. The good news? There are exercises and self-care strategies you can implement to help yourself without the need for professional intervention.
What is the Sacroiliac Joint (SI Joint)?
The sacroiliac joint connects the sacrum (the triangular bone at the base of your spine) to the ilium (part of your pelvis) on both sides of your body. These joints help transfer weight between your upper body and lower body while absorbing shock during activities like walking, running, or lifting.
Although the SI joint doesn’t allow for much movement, its role is crucial for stability and efficient body mechanics.
Why is the SI Joint Important for Lower Back Health?
Your SI joints act as a critical link between your spine and pelvis. When functioning properly, they provide the stability needed to support your lower back and hips. Dysfunction occurs when the joint becomes either too mobile (hypermobile) or too restricted (hypomobile), leading to pain and biomechanical issues.
Dysfunction in this joint can affect posture, cause gait imbalances, and lead to compensatory issues elsewhere in the body—especially in the lower back, hips, and legs.
Common Causes of SI Joint Dysfunction
- Prolonged sitting or standing
- Repetitive impact activities (running, jumping)
- Muscle imbalances, particularly weak glutes or core muscles
- Pregnancy, due to ligament laxity and pelvic changes
- Poor posture or incorrect lifting techniques
Symptoms of SI Joint Dysfunction
Recognizing the symptoms of SI joint dysfunction is essential for self-diagnosis and treatment. Common signs include:
- Lower back pain, especially on one side
- Pain in the buttocks, pelvis, or groin
- Discomfort when standing up after prolonged sitting
- Pain that worsens with walking, climbing stairs, or bending
- A feeling of stiffness or reduced mobility in the hips
If these symptoms sound familiar, the following sections will guide you through self-help exercises designed to reduce pain and restore SI joint function.
Preventing SI Joint Dysfunction Through Movement and Strengthening Exercises
Strengthening key muscles and promoting balanced mobility in the pelvis and lower back can help prevent SI joint dysfunction. Here are essential exercises:
1. Core and Pelvic Stability (Bird Dog Exercise)
The bird dog exercise is excellent for stabilizing the core and SI joint by targeting the abdominals and back muscles.
How to do it:
- Start in a tabletop position (on hands and knees).
- Extend your right arm forward and your left leg back, keeping your core engaged.
- Hold for 5-10 seconds, then switch sides.
- Perform 8-10 reps per side.
Tip: Maintain a neutral spine throughout the movement to avoid straining your lower back.
2. Glute Bridges for Pelvic Stability
Weak glutes can lead to instability in the SI joint. Strengthening them helps stabilize the pelvis and reduce SI joint stress.
How to do it:
- Lie on your back with knees bent and feet flat on the floor.
- Engage your core and squeeze your glutes as you lift your hips off the ground.
- Hold for 5 seconds at the top, then lower down.
- Perform 10-15 reps.

What to Do If the SI Joint is Already Dysfunctional (Self-Help Fixes)
If you’re experiencing pain or limited mobility due to SI joint dysfunction, these targeted exercises and mobility drills can help alleviate symptoms.
1. SI Joint Reset Technique
Sometimes, the SI joint becomes “stuck” or misaligned. A gentle resetting technique can help restore movement and relieve tension.
How to do it:
- Lie on your back with one knee bent and the opposite leg straight.
- Press your bent knee into your hands while applying slight resistance for 5-10 seconds.
- Switch sides and repeat.
This movement gently mobilizes the joint and can help “unlock” restrictions.

2. 90/90 Hip Stretch for SI Joint Mobility
Improving hip mobility can ease tension on the SI joint and reduce pain.
How to do it:
- Sit on the floor with your front leg bent at 90 degrees and your back leg bent behind you at 90 degrees.
- Lean forward slightly over your front leg to feel a stretch in your hips.
- Hold for 30 seconds, then switch sides.
This stretch helps improve hip flexibility, reducing compensatory strain on the SI joint.
3. Self-Massage with a Foam Roller
Using a foam roller to release tight muscles around the glutes, lower back, and hips can provide relief.
- Focus on rolling the glutes, hamstrings, and the area around the sacrum.
- Spend 1-2 minutes on each side, avoiding excessive pressure on bony areas.

Consistency Is Key: Create a Routine
To improve SI joint function, consistency is crucial. A daily or every-other-day routine that includes core activation, stretching, and foam rolling will yield the best results. Start slowly and increase intensity as your pain subsides.
When to Consider Medical Help
While most SI joint dysfunction can be managed with exercise and self-care, you should consider seeking professional help if:
- Pain persists for more than a few weeks
- You experience numbness or tingling in your legs
- Pain worsens despite consistent self-treatment
Final Thoughts
SI joint dysfunction is a common but manageable cause of lower back pain. By incorporating simple exercises like core strengthening, glute activation, and mobility drills, you can relieve pain, prevent future flare-ups, and take control of your joint health. Don’t underestimate the power of movement—these exercises are designed to empower you to help yourself.
