The SI joint refers to the sacroiliac articulation, two joints on either side of the sacrum which work to stabilize the pelvis and lower spine. Several tough ligaments hold the SI joint in place and allow it to function as a shock absorber for the spine. Pain in the SI joint and pelvis while stretching may relate to a number of conditions, including postural issues, muscular imbalances and arthritis.
Arthritis and Aging
One of the most common causes of SI joint pain and pelvic pain is degenerative arthritis such as osteoarthritis and rheumatoid arthritis. Aging can also be a factor in SI joint pain, as over the years the joint may stiffen and lose all mobility. Speak to your doctor or health care practitioner if you have arthritis and experience pain in the SI joint and pelvis while exercising or stretching.
Muscle Imbalances
SI joint and pelvic pain during stretching can also indicate imbalances amongst the muscles that stabilize the pelvis: the hip flexors, abdominals, erector spinae and hamstrings. These imbalances often stem from postural issues such as lordosis, commonly known as sway back, or a pronounced pelvic tilt to one side.
Treatment
Treatment for SI joint pain that also affects the pelvis also depends on the extent to which the pain hampers mobility. Some forms of SI joint and pelvic pain respond to rest ice and heat. Others require more deliberate treatments such as manipulation by a massage therapist, chiropractor or osteopath, pelvic supports or braces, physical therapy or sacroiliac joint injections, typically a corticosteroid designed to reduce the inflammation and return mobility.
Water Therapy
If the pain in your SI joint and pelvis becomes extreme, stretching in the pool represents a viable option. Buoyancy ensures that the SI joint and the pelvis will endure less weight bearing while exercising or stretching, thus allowing a larger range of stretching positions. Water also provides gentle resistance to help strengthen the stabilizer muscles of the pelvis and lower back.
