During Yeoman's Test, where is pressure applied?

• A. Contralateral PSIS
• B. Ipsilateral PSIS
• C. Lateral knee
• D. Upper back

Answer: (B)

Yeoman's Test is a clinical assessment used to evaluate hip and sacroiliac joint function and to identify potential sources of low back pain. During this test, pressure is applied to the ipsilateral PSIS (Posterior Superior Iliac Spine) of the hip being assessed. Applying pressure here helps to stress the tissues and structures around the sacroiliac joint and can reproduce symptoms associated with dysfunction or irritation in that area. The response elicited by pressure on the ipsilateral PSIS can indicate whether there is a problem in the sacroiliac joint or surrounding musculature.

By targeting the ipsilateral PSIS, the tester can assess for pain that may indicate an underlying condition, such as sacroiliac joint dysfunction, and differentiate it from other potential causes of pain. This localized pressure effectively helps to identify discrepancies in joint stability or integrity during the test.
