At the Harris Health System, many clinicians practice Shirley Sahrmann's movement impairment syndromes. Utilizing Sahrmann's principles helps guide the clinician toward movement dysfunctions often caused by prolonged postures and repetitive micro-trauma. Since Sahrmann focuses on movement impairments, her syndromes are named using pathokinesiology and kinesiopathology. For the purposes of learning, in this post I will include pathoanatomical diagnoses that relate to lumbar extension rotation syndrome (ERS).
When performing a lumbar evaluation, assessing for lumbar extension rotation should be a priority. General presentation includes: >55 years old, chronic low back pain, and may be involved in a rotational sport (golf, tennis, etc). On physical examination, you will observe an exaggerated lumbar lordosis, paraspinal muscle asymmetry, excessive pelvic rotation during gait, and hinging during cardinal plane extension testing. They will often complain of unilateral lumbar pain that increases with extension and is relieved with non-weight bearing lumbar flexion.
In addition to my findings during my functional assessment and observation (stated above), there are many clinical tests used to diagnose lumbar ERS. A few tests I commonly perform are 1) supine bent knee fallout, 2) prone knee bend, 3) quadruped hip extension, and 4) single limb stance. With each of these tests, the examiner should be looking for lumbopelvic compensation (extension and rotation) on the involved side. This compensation generally occurs due to poor timing, coordination, and strength of the core and hip musculature.
Try these tests on a few of your patients and watch how their low back compensates! Let me know if you have any questions or want more information regarding other tests you can perform.

Very interesting! I am also not very familiar with this and would love some follow up on treatment approach. Thanks.

Rachel and Tim, please email me at firstname.lastname@example.org so that I can provide you with some follow up information. I apologize for the delayed response- my residency was coming to an end and I got very behind other things.
