Reliability of the Lumbar Flexion, Lumbar Extension, and Passive Straight Leg Raise Test in Normal Populations Embedded Within a Complete Physical Examination

STUDY DESIGN: The study measured the reliability of the passive straight leg raise (SLR) test and lumbar range of motion (LROM) tests measured as continuous variables embedded within a comprehensive physical examination. OBJECTIVES: To determine the reliability of the SLR and LROM test scores when they are measured with a Cybex electronic inclinometer (Lumex, Inc., New York, NY) within a physical examination.
