Execution:
- Patient is in supine lying position with the legs straight and feet 20cm apart
- The patient is asked to try to raise the legs 5cm one after the other without bending the knee
- If lifting of the leg is painful, the examiner applies manual compression at both anterior superior iliac spines or by the use of a sacroiliac belt and asks the patient to repeat the test
Positive Outcome: Movement is no longer painful after compression is applied

| Comment: O’Sullivan et al. (2007) suggest that the ASLR might be helpful in order to distinguish patients with pelvic-girdle pain and a reduced force closure of the SI joint from patients with pelvic-girdle pain due to an excessive force closure. In the latter group, patients usually have a negative outcome, while compression in the second step of the test might actually be provoking | |||||
