Lasegue Drop Test
What is Lasegue Drop Test?
Lasegue Drop Test is used to test for lumbar spine pain due to spondylarthritis, spondylitis, or disk herniation.
- It’s also used to assess the sacroiliac joint.
How it's Performed?
- The patient is supine.
- The examiner performs the test on the affected side as in the Lasegue test, raising the leg until the patient begins to feel discomfort.
- Then the examiner lets go of the leg from this position.
What does a positive Lasegue Drop Test mean?
- Suddenly and unexpectedly letting go of the leg precipitates reflexive contraction of the muscles of the back and buttocks.
- It is primarily the iliopsoas that contracts, placing traction on the transverse processes of the lumbar spine.
- Patients will report pain in the presence of disorders of the lumbar spine (spondylarthritis, spondylitis, or disk herniation) or disorders of the sacroiliac joints
- For a differential diagnosis it must be borne in mind that Lasegue Drop Test can also intensify visceral pain such as that caused by appendicitis.
