When performing “core training” it is essential to establish whether or not your client is stable or not. Stabilization means being able to control the amount of movement about the joint during loading. Stabilization of the pelvic girdle takes place both at the pubic symphysis and at the sacroiliac joints.
The sacroiliac joint is a synovial joint, a trilayer structure between the ilium and the costal element of the sacrum. The pubic symphysis is a non-synovial joint, which contains a thick fribrocartilaginous disk between thin layers of hyaline cartilage. As we age the SIJ degenerates, smooth undulations appear along the margins of the joint and the bone begins to compact. The effect of degeneration on function is unknown.
The active bent leg raise test is an excellent test for stability. To gain information about both muscle recruitment and timing we test our client in the supine position, knees bent. Palpate the transverses abdominis deep in the abdomen approximately 2.5 cm (1 in.) medial to the ASIS. When the TA contracts, feel for an increase in tension (not bulging) at this point. When the internal oblique contracts, feel for a distinct bulging. With the other hand, palpate multifidus. Ask the patient to lift the foot off the ground, keeping the hip and knee flexed.
Note the ability to maintain a stable low back and pelvis girdle.
