SI Joint Special Tests | Cluster of Laslett

The video tutorial covers the diagnosis of sacroiliac (SI) joint dysfunction using the Laslett cluster of tests. Initially, five tests were included, but Gaenslen's test was later removed, leaving four key tests: thigh thrust, SI distraction, sacral thrust, and compression. The video explains and demonstrates each test, highlighting the procedure and criteria for a positive result. It concludes with a discussion on the sensitivity and specificity of the tests, emphasizing that only two of the four tests need to be positive to suggest SI joint dysfunction.

What is the primary purpose of the cluster of Laslett tests?

• To diagnose sacroiliac joint dysfunction

• To diagnose hip joint dysfunction

• To assess lumbar spine issues

• To evaluate nerve damage

Which test was removed from the original cluster of Laslett due to lack of clinical value?

• Gaenslen's test

• Thigh thrust test

• Compression test

• Sacral thrust test

During the thigh thrust test, what is the position of the patient's symptomatic leg?

• Hip extension with knee straight

• Hip flexion with knee bent

• Hip adduction with knee straight

• Hip abduction with knee bent

What is the main indicator of a positive result in the SI distraction test?

• Decreased muscle strength

• Familiar pain provocation

• Increased range of motion

• Improved joint stability

In the sacral thrust test, where is the manual contact applied?

• On the S2 level of the sacrum

• On the femur

• On the ASIS

• On the lumbar spine

What is the position of the patient during the compression test?

• Prone on the symptomatic side

• Sideline on the symptomatic side

• Standing upright

• Supine on the asymptomatic side

How many of the four tests need to be positive to suggest SI joint dysfunction according to the updated cluster of Laslett?

• One

• Four

• Two

• Three
