Gluteal Strengthening for Sacroiliac Joint Pain


Pain associated with SI joint dysfunction can radiate to the groin or low back. SI joint dysfunction can be associated with trauma. Non-traumatic factors including malalignment or leg length discrepancies.

The SI joints are located at the back of the pelvis, one on each side. The SI joint has a small range of motion. Its primary function is stability and transmitting forces from the spine, through the pelvis and lower extremity. In the case of instability, research has suggested that focused strengthening of the gluteus maximus and gluteus medius is a useful treatment. These muscles are important for maintaining stability at the hip and pelvis.

Various modifications on supine bridging, is an example of an exercise that isolates the gluteus maximus. There are numerous structures in the area that can cause localized or referred pain in the low back, buttock and groin. A physical therapist can help differentiate between these structures, and create a plan to address those impairments.
