A patient with “iliopsoas syndrome” will walk into the office flexed forward and leaning to one side, complaining of significant central lower back, groin, and sacroiliac pain. They may have sciatic pain in the opposite leg. Acute, severe cases may have a hip flexion contracture and an inability of the patient to lie prone. Hypertonicity/shortening of the iliopsoas compresses the hip joint, the SI joint, and the lumbar spine. The iliopsoas is a muscle of postural balance. Iliopsoas spasm causes “pelvic side shift”; a contraction of the left iliopsoas produces pelvic side shift right. With pelvic side shift right, a lumbar curve convex left is produced. Over time, the pelvic side shift and compressive load cause sacral base declination. The lumbar spine then compensates for the pelvic side shift and sacral base declination with a lumbar curve convex to the right. Effective treatment of the “key” somatic dysfunctions (L1 or L2, and tender points / trigger points) are essential for pain reduction and for long-lasting effects from manipulative treatment. Removing somatic dysfunction, improves muscle hypertonicity, normalizes gait and biomechanical function, and decrease the chance of developing chronic pain due to central sensitization.
