Which sign indicates weak oblique abdominals during ASLR?

During an active straight leg raise, the oblique abdominal muscles help keep the trunk and pelvis stable as the leg lifts. If these muscles are weak, the body tends to rotate the trunk toward the leg being raised because there isn’t enough rotational stability to resist that movement. So significant trunk rotation toward the raised leg is the best indicator that the oblique abdominals are weak. Pain in the SI joint points to a joint issue rather than core control. Hip abduction weakness would show up as difficulty lifting the leg away from the body or keeping the pelvis level, not as rotation of the trunk toward the raised leg. Ankle dorsiflexion limitation affects the ankle, not the trunk stability during the leg raise.
