    Lasègue’s Test

Indications

Lasègue’s Sign is very similar to the Straight Leg Raise test, were signs of lower back pain can be elicited by flexing the leg. However this test is performed in a seated position.

Procedure

Patient seated with knees flexed 90°, while examiner extends the patient’s knee.

Interpretation

Leg pain Radiculopathy
Increased resistance Hamstring tightness/contracture

Clinical Notes

Test is essentially the same as performing a supine Straight Leg Raise as the angle at the hip is ultimately the same, thus resulting in the same stretch of the sciatic nerve.
