Pelvic asymmetry is when the bones of the pelvis differ in alignment or shape. In theory, the cause for a detectable asymmetry could be functional and/or structural. In clinical practice, it's common to observe pelvic asymmetry in individuals with pain and movement limitations. And from this observation, many clinicians hope to evaluate and treat asymmetry as a means of providing relief to their patients/clients. But, there's a big problem. To be able to intervene, you need to be able to reliably test asymmetry. And studies suggest that palpation, or the manual assessment of bony landmarks, has questionable reliability. As a solution to this problem, many clinicians use hip range of motion testing as a proxy for pelvic asymmetry. The idea is that if there's a significant asymmetry in passive range of motion tests for the hip, you can rule in pelvic asymmetry. One such test is the Ober's Test. The group of clinicians (and non-clinicians) who use this test are trained through the Postural Restoration Institute. They refer to the test as the Adduction Drop Test. The Ober's test has a long history in physical therapy. And traditionally, it is thought of as a test of Iliotibial Band Length. At Postural Restoration Institute courses, they teach the test as an indication of a "forward" or anteriorly rotated left hemi-pelvis. They use this test in isolation to determine if someone is in the left AIC pattern, PEC pattern, or neutral. A positive test is when the leg cannot extend, and/or cannot adduct so that the knee touches the table. From this practice arise many questions: 1. Is the Ober's test reliable? 2. How much adduction is normal at the hip joint? 3. Is the Ober's test valid for identifying pelvic asymmetry? 4. Is the Ober's test in isolation robust enough to rule in asymmetry? 5. What are the common pitfalls of testing? Are they common? 6. How might individual morphology impact test results? In this video, we answer all of these questions, with examples, clinical expertise, and research to back it up.
