Movement Comparator

Active tests can substitute for the Ober test when passive testing is unavailable, especially in online coaching. Passive and active tests can serve the same comparator purpose if they capture the targeted movement option. In the article's clinical framework, tests are used as comparators rather than definitive diagnoses by themselves. A movement test is useful when it shows whether an intervention is moving the person in the intended direction. Split squats, sprinter step-ups, sprinting, and single-leg stance can show whether hip extension is maintained without compensatory lumbar arching or hip flexion.
