Gaenslen's test
A clinical test used in the diagnosis of sacroiliac joint dysfunction
Gaenslen's Test[edit | edit source]
Gaenslen's Test is a clinical examination procedure used to detect musculoskeletal abnormalities and primary-chronic inflammation of the sacroiliac joint. It is commonly employed in the assessment of sacroiliitis and other conditions affecting the pelvis and lower back.
Procedure[edit | edit source]
The test is performed with the patient lying supine on an examination table. The patient is positioned such that one buttock is at the edge of the table. The examiner then flexes the knee and hip of the leg that is on the table, while the other leg is allowed to hang off the edge. The examiner applies pressure to the flexed knee, pushing it towards the patient's chest, while simultaneously applying downward pressure on the hanging leg. This maneuver stresses the sacroiliac joint and can elicit pain if there is an underlying pathology.
Interpretation[edit | edit source]
A positive Gaenslen's Test is indicated by the reproduction of pain in the sacroiliac region. This suggests the presence of sacroiliac joint dysfunction, which may be due to sacroiliitis, ankylosing spondylitis, or other inflammatory conditions. It is important to note that Gaenslen's Test should be used in conjunction with other diagnostic tests and clinical findings to confirm a diagnosis.
Clinical Significance[edit | edit source]
Gaenslen's Test is a valuable tool in the differential diagnosis of lower back pain. It helps distinguish between pain originating from the sacroiliac joint and other potential sources such as the lumbar spine or hip joint. The test is particularly useful in patients presenting with symptoms of spondyloarthritis or other inflammatory disorders.
Limitations[edit | edit source]
While Gaenslen's Test is useful, it is not definitive on its own. False positives can occur, and the test may not be suitable for patients with severe hip or knee pathology. Additionally, the test's accuracy can be influenced by the examiner's technique and the patient's ability to relax during the procedure.
