Pain around the low back, buttock, or pelvis may be coming from the SI joint
SIJ dysfunction (sacroiliac joint dysfunction) is a common source of pain that is often mistaken for “just low back pain.” The sacroiliac joints connect the spine to the pelvis and help transfer load during walking, lifting, sitting, and standing. When movement becomes either too stiff or too mobile, symptoms can develop. Physiotherapy interventions such as exercise and manual therapy have good evidence for reducing pain and disability.

🤝 Our Whole-Body Clinical View
We don’t only focus on the joint itself. The SI joint works as part of a full load-transfer system involving the lumbar spine, pelvis, hips, abdominal wall, diaphragm, pelvic floor, and surrounding fascia. When breathing patterns are restricted, one hip becomes stiffer, or the pelvis is overloaded during repetitive lifting, walking, pregnancy, or sport, the SI region may begin to compensate. From this perspective, SIJ dysfunction often reflects impaired force transfer between the trunk and lower limbs, rather than a single isolated joint problem. Current evidence supports a combined approach of manual therapy, stabilization exercises, movement retraining, and load management.
If low back or pelvic pain keeps returning and feels difficult to localize, the SI joint may be an important part of the picture.
