Active SLR Test is used to indicate which conditions?

• A. Disc herniation
• B. SI joint pathology and pubic ring instability
• C. SI joint dysfunction
• D. Upper motor neuron lesion

Answer: (B)

The Active Straight Leg Raise test is about how well the pelvic ring bears and transfers load during a active leg lift. When you lift a straight leg while lying on your back, any pain in the sacroiliac area or around the pubic symphysis, or a noticeable difficulty keeping the pelvis stable, points to problems with the SI joints or instability of the pubic ring. Those structures are directly loaded during the movement, so dysfunction here shows up as pelvic instability or SI joint pain.

Disc-related nerve root issues typically cause radicular symptoms that follow a nerve distribution rather than localized pelvic instability, and upper motor neuron lesions produce different signs such as spasticity or hyperreflexia rather than pelvic instability during an ASLR. So the test most specifically indicates sacroiliac joint pathology and pubic ring instability.
