Unlike the hip or shoulder, the SI joint is designed primarily for stability rather than a large range of motion. The surfaces of the sacrum and ilium have an irregular, interlocking shape that helps them fit together, while strong ligaments surrounding the joint provide additional stability. There is some movement at the SI joint, but it is very small.
What Can Cause SI Joint Pain?
The SI joint can become painful or irritated for a variety of reasons. Trauma, pregnancy, arthritis, repetitive stress, and changes in the way the pelvis and surrounding muscles are working can all contribute.
Pain related to the SI joint is generally felt in the lower back or pelvic region and may occur on one side or both sides. Certain movements—such as standing up from a chair, bending, climbing stairs, or changing positions—may make symptoms more noticeable.
Because so many structures in the low back, pelvis, and hips can produce similar symptoms, it isn’t always easy to determine whether the SI joint itself is the source of pain. An evaluation by a physical therapist, physician, or other qualified healthcare professional can help determine what may be contributing to your symptoms.
How Can the Tr.uCore Method Help?
At Tr.uCore, we look at more than the painful area. The way the pelvis, spine, hips, and surrounding muscles work together can influence how much stress is placed on the SI joint.
The Tr.uCore Method teaches you how to engage the transversus abdominis—the deep abdominal muscle that helps stabilize the trunk—while learning to release muscles that may be working harder than necessary. This combination of stability and relaxation can help improve how the pelvis and spine move together.
Rather than trying to force the SI joint into a particular position, we focus on developing better body awareness, control, and movement patterns. Learning how to stabilize your core while allowing other muscles to relax can help you move with less unnecessary tension and may reduce irritation around the pelvis.
Can Yoga Help?
Yoga can be a useful part of that process. Gentle, controlled movement can improve mobility, body awareness, and coordination while allowing you to pay attention to how your pelvis and spine are moving.
Some postures that may be appropriate for people experiencing SI joint discomfort include:
- Janu Sirsasana (Single-Leg Forward Fold)
- Marichyasana (Sage Twist)
- Anantasana (Side-Reclining Leg Lift)
- Baddha Konasana (Bound Angle Pose)
- Garudasana (Eagle Pose)
However, these poses aren’t appropriate for everyone, particularly during an acute flare-up. The goal is not to push into a deeper stretch or force the pelvis into a particular position. Instead, move slowly and pay attention to how your body responds.
Be Careful With Twists
Some of these poses involve rotation. When twisting, ease into the movement rather than trying to force yourself deeper. Allow your pelvis and spine to move naturally together, and avoid using your arms to pull yourself farther into the twist.
At Tr.uCore, we believe that effective movement isn’t about forcing your body into alignment. It’s about understanding how your body moves, developing control, and learning to move with less unnecessary tension.
If you’re dealing with back or leg pain and aren’t sure what movements are appropriate for you, an individualized assessment can be a much better place to start than simply searching for exercises online.For more tips on pain relief and injury prevention, sign up for our newsletter here or follow us on social media
