Yeoman Test is a provocative test that is used to evaluate the sacroiliac joint dysfunction.
How it’s Performed?
The patient is prone with the knee flexed 90°.
The examiner raises the flexed leg on the examining table, hyperextending the hip.
What does a positive Yeoman Test mean?
The first part of this test initially places stress on the posterior structures of the sacroiliac joint; later the stress shifts to the anterior portions, primarily affecting the anterior sacroiliac ligaments.
Pain in the lumbar spine suggests the presence of pathologic processes at that site.
Anterior thigh paresthesia may indicate a femoral nerve stretch.
Another study 3 by Parisa Nejati to assess the reliability and validity of motion palpation and pain provocation compared with sacroiliac joint (SIJ) block as the gold-standard assessment method of patients with sacroiliac joint dysfunction (SIJD), he found the sensitivity was (64.1%) and specificity was (33.3 %) for Yeoman Test.
Other structures that are stressed with this maneuver include the lumbar spine, the hip joint, and the iliopsoas muscle.
