Did you know  that eight out of 10 Americans will experience back pain at some point in their lives. When you add in shoulder, hip, and other joint pain, we’re all going to deal with pain at some point.

 But even after physical therapy, chiropractic, and massage — at least 6 of those 8 will be back in pain within two years.

Why?

Because those treatments address the body — with no regard for the brain.

Your brain directs how you stand, move, and hold alignment, operating unconsciously—just like your heartbeat. When it misinterprets signals from your body, it can lead to imbalances that place pressure on areas like the sacroiliac (SI) joint, a key stabilizer between your spine and pelvis. If this joint becomes misaligned due to postural issues, no amount of massage or bodywork alone will correct the cause of the pain.

Watch the full 10-minute masterclass below revealing how to transform your posture starting from the ground up.

What Causes SI Joint Pain?

The sacroiliac (SI) joint connects the spine to the pelvis and plays a pivotal role in maintaining stability. When exposed to uneven weight distribution or postural imbalances, the SI joint can become “stuck,” leading to inflammation and discomfort.

Key contributors to SI joint pain include:

• Foot Posture Issues: Imbalanced feet can tilt or rotate the pelvis, increasing strain on the SI joint.

• Weak Core Muscles: A weak core destabilizes the pelvis, reducing the SI joint’s ability to support the body.

• Brain-Body Communication Errors: When the brain receives inaccurate signals from the feet or eyes, it may direct the body to adopt compensatory postures, further exacerbating pain.

By understanding these underlying causes, we can move beyond symptom management to effectively address and resolve SI joint pain at its source.

The Importance of Addressing the Root Cause of SI Joint Pain

Most people focus on managing the symptoms of SI joint pain—whether through temporary pain relief methods or isolated exercises—but neglect to consider how underlying imbalances contribute to the issue. The key to long-term relief lies in identifying and correcting the factors that create stress on the sacroiliac joint in the first place.

For instance, imbalances in the feet or hips don’t just affect one area—they create a chain reaction throughout the body. Over time, these misalignments force the SI joint to overcompensate, resulting in stiffness, inflammation, and discomfort. By targeting these root causes through a combination of sensory recalibration and strategic movement, you can unlock your body’s natural ability to heal and restore alignment.

This holistic approach not only alleviates pain but also helps prevent recurring issues, ensuring better mobility and improved quality of life. Let’s dive deeper into the specific causes of sacroiliac pain and explore how to address them effectively.

Causes of Sacroiliac Pain: Understanding the Foundation

Sacroiliac (SI) joint pain often surprises individuals by its connection to postural imbalances throughout the body. While the sacroiliac joint itself plays a stabilizing role, the root causes often stem from broader issues in muscular and skeletal alignment. These imbalances place uneven pressure on the pelvis, pulling it out of alignment and causing discomfort or pain over time.

What many don’t realize is that muscle tension on either side of the pelvis is often controlled by the brain’s interpretation of sensory feedback. Your feet, eyes, and overall posture continuously send signals to your brain, which then directs how your body maintains balance. When that sensory input is flawed—such as through instability in the feet or misaligned weight distribution—the pelvis compensates, potentially leading to pain and inflammation in the SI joint.

Test Your Foot Stability: A Quick Assessment

Postural imbalances often originate in the feet, making it essential to assess their stability. Try this simple test:

1. Stand with both feet flat on the ground.

2. Lift one foot off the floor and observe any movement in the supporting foot.

3. Does your foot roll inward or outward? Repeat with the other foot.

These subtle shifts can reveal imbalances that ripple up to the pelvis and SI joint, contributing to chronic pain. Recognizing and addressing these misalignments early is the first step to restoring stability and reducing strain on the SI joint.

Exercises to Unlock and Support Your SI Joint.

1. Balance Your Foot Posture

Improving foot posture is a crucial first step in promoting SI joint health. Misaligned feet destabilize the lower body, putting unnecessary strain on the SI joint. Incorporate these strategies to create a stable foundation:

• Therapeutic Insoles: Posturepro’s insoles stimulate foot receptors, enhancing muscle tone, alignment, and stability. These insoles encourage proper weight distribution, reducing strain on the pelvis.

• Foot Proprioception Exercises: Practice single-leg balance exercises or use a wobble board to activate and strengthen the small stabilizing muscles in your feet. Aim for 30 seconds on each foot, gradually increasing time as your balance improves.

2. Gentle Movements to Release SI Joint Tension

Simple exercises, like the Pubic Symphysis Release and Knee-to-Chest Stretch, help release tension in the SI joint. These gentle movements reduce strain and can unlock stuck joints.

3. Posturepro’s Brain-Based Alignment Technique

Our brain-based alignment approach corrects SI joint imbalances by recalibrating how sensory inputs from the feet, eyes, and jaw influence posture. This unique method improves alignment and reduces strain on the SI joint.

4. Strengthen the Core

A strong core stabilizes the pelvis, reducing the likelihood of SI joint misalignment. Incorporate exercises like Planks and Glute Bridges to build strength and support pelvic stability.

5. Targeted Stretches for SI Joint Relief

Stretching muscles around the SI joint releases tension and aids alignment. Effective stretches include:

• Figure Four Stretch: Lie on your back, cross one ankle over the opposite knee, and gently pull the opposite thigh toward your chest.
• Side-Lying Quad Stretch: Lie on one side, bend the top knee, and pull the ankle toward your glute.

Reset Your SI Joint with 3 Popular Movements

1) Pubic Symphysis

While in the supine position with your knees bent and your feet flat on the floor, place a softball or rolled up pair of socks between your knees. Very gently squeeze for a count of 5 and then slowly release. Do about 3-5 of these, but let your pain be your guide. In other words, stop if it hurts.

Taking the tension out of your quadriceps muscles may help alleviate some of your SI pain. In the image above, the model is demonstrating the easiest type of quadriceps stretch, where you lie on one side and grasp your foot, ankle or even your shin behind you, then gently pull it toward you.

If you can’t reach, consider using a strap or belt around your foot to extend the reach space.

This position is not for everyone. If you are not used to exercising and you have SI joint pain, you may want to forego the side lying quad stretch as the position, more so than the stretch itself, may stress the joint. The side lying stretch is for beginners.

Stretching the outer hip muscles,1 which are the opposing muscles to the inner thighs, may indirectly have the same effect as adduction, albeit in a less intense way. Plus, it can help release chronic tension that may be at least partially responsible for routine SI joint misalignment.

Pull your knees to your chest. If you’re back is up for it, which in part may be a matter of strong ab muscles, try the double knees to chest exercise.

Optimize Foot Mechanics and Your Gait Cycle

In addition to regular movement exercises, focusing on foot mechanics can transform the way you walk, stand, and move. Our tools are designed to enhance your gait cycle by targeting proper foot engagement and alignment. By addressing imbalances in foot mechanics, you can improve overall posture, reduce strain on joints, and achieve better body symmetry.

This approach supports optimal movement patterns and complements posture exercises perfectly.
