== Purpose  ==
 
The posterior shear test is a pain provocation test used to determine the presence of [[Sacroiliac_joint|sacroiliac dysfunction]]. It is used (oftenly&nbsp;in pregnant women) to distinguish between pelvic girdle pain and low back pain.<ref name="Zeven">JK Freburger, DL Riddle. Using published evidence to guide the examination of the sacroiliac joint region. Phys Ther. 2001; 81:1135–1143</ref>
 
The test is&nbsp;also known as:
 
*PPPP test
*P4 test
*Thigh trust test
*Posterior pelvic pain provocation test<br>
*POSH test<br>
 
== Technique<br>  ==
 
With the patient supine, the hip is flexed to 90° (with bended knee) to stretch the posterior structures and the femur is adducted towards the midline. By applying axial pressure along the length of the femur, the femur is used as a lever to push the ilium posteriorly. One hand is placed beneath the sacrum to fixate its position while the other hand is used to apply a downward force to the femur.<ref name="Vijf">NA Broadhurst, MJ Bond.

New York: Churchill Livingstone; 1997</ref><br>
 
The test is positive for pelvic girdle pain if the axial pressure provoques pain over the sacroiliac joint of the provoked side that is familiar to the patient.

== Evidence  ==
 
The gold standard to evaluate sacroiliac pain provocation tests is an intra-articular injection of a local anesthetic into the sacroiliac joint, under guidance of radiological imaging.<ref name="Acht">BA Zelle, GS Gruen, S Brown, S George. Sacroiliac dysfunction: evolution and management. Clin J Pain. 2005; 21(5):446-455</ref><ref name="Negen">JK Freburger, DL Riddle. Using Published Evidence to Guide the Examination of the Sacroiliac Joint Region. Physical Therapy. 2001; 81(5):1135-1143</ref> Several studies have compared existing pain provocation tests and concluded that not a single test but an [[Test_Item_Clusters_for_Sacroiliac_Dysfunction|array of tests]] should be used to confirm diagnosis (grade A recommendation).&nbsp;<ref name="Drie">M Laslett et al.

Specificity, sensitivity, and predictive values of clinical tests of the sacroiliac joint: a systematic review of the literature.

Most commonly used tests with both sensitivity and specificity greater than 60% are:<ref name="Zes" />

*[[SI compression test|Compression test]]
*Thigh trust test
*[[Gaenslen Test|Gaenslen’s test]]  
*Sacral trust test
 
Lanslet et al (2005) state that no further examination is wishfull if both distraction and thigh trust test provoke familiar pain because of their high individual sensitivity and specificity. If only one test or 2 other tests are positive, further testing is required to obtain a valid result.<ref name="Drie" />&nbsp;
 
The posterior pelvic pain provocation test has a high intertester reliability of 94,1 (kappa=0,64-0,82 and p&lt;0,001) and a high degree of sensitivity (80-88%) and specificity (100%) in 2 studies of moderate to high methodological quality.<ref name="Drie" /><ref name="Zes" /><ref name="Vijf" />&nbsp;Positive predictive value ranges from 25% to 70% and negative predictive value goes from 88% to 92%.<ref name="Vier">CC Yung, M Fredericson, M Smuck.
