The sacroiliac (SI) joints connect the sacrum at the base of the spine to the pelvis. Although these joints move only about two to four millimeters during weight bearing and forward bending, they play an important role in shock absorption for the spine and in transferring weight as you walk.
SI joints have a complex structure, with both hyaline and fibrocartilage surfaces, ridges, and depressions that fit together. They are designed for stability rather than large movement. They can become stiff or “locked” over time, or become overly mobile when the ligaments that support them are strained. Either pattern can contribute to pain and difficulty with everyday movement.
SI joint pain can be overlooked because it often resembles other forms of low back, buttock, pelvic, or leg pain. A thorough evaluation helps identify the movement, alignment, strength, and posture factors contributing to your symptoms.
SI joint dysfunction may develop from wear and tear, injury, or changes in the way the pelvis is supported.
Symptoms can be difficult to distinguish from other types of low back pain. Many people experience a confusing pattern of back and pelvic pain.
A well-rounded rehabilitation program can help calm pain and inflammation, improve mobility and strength, and make daily activities easier. Your care is guided by whether the SI joint is primarily stiff or loose.
When a joint is stiff or locked, mobilization and specific exercises may be used to improve SI joint movement. When the joint is too loose, such as with arthritis or SI ligament injury, stabilization treatment may be chosen to support correct alignment. Stabilization exercises focus on posture and muscle training.
Therapy sessions may be scheduled two to three times each week for up to six weeks, depending on your needs and plan of care.
Learn practical ways to control symptoms and manage your condition with greater confidence.
Learn correct posture and body movements that can reduce strain on the SI joints.
Work toward optimal SI joint movement, alignment, strength, and stability for daily life.
For a loose and painful SI joint, a sacroiliac belt may be issued to help stabilize the area. The belt wraps around the hips to gently squeeze and hold the SI joints together, supporting the pelvis and helping limit painful excessive motion.
Your physical therapist can determine whether this type of support may fit into your individualized treatment plan.
