3. Excessive Lumbar Extension
This chapter will introduce the MSI syndrome of lumbar extension. You will learn the primary movement assessment tests to identify a patient who fits into a lumbar extension syndrome. This includes primary tests of active lumbar side bend/rotation, seated hip flexion, supine hip external rotation/abduction, and prone hip internal and external rotation. Based on the results from movement assessments, you will learn corrective exercises to treat the identified movement impairments.
