Pelvis

Active straight leg raise

ASLR

What you examine
Load transfer between trunk and leg through the pelvis, in pelvic girdle pain.
Procedure
Supine, legs extended. Have the patient lift one leg five centimetres and score the effort from 0 to 5. Repeat with manual compression of the pelvis.
Positive when
Clearly more effort or pain on one side, which decreases as soon as you compress the pelvis.
What the test is worth
Good reliability and a strong association with the severity of pelvic girdle pain, especially postpartum. Sensitivity around 0.87, specificity around 0.94 in that group.
Caution
That compression helps is immediately the treatment direction: it argues for a belt or for training the muscles that deliver the same compression actively.
Joint
Sacroiliac joint
