Purpose
[edit | edit source]

To detect the compression and/or irritation of the sciatic nerve by the piriformis muscle.

Technique
[edit | edit source]

 


With the patient in side-lying with the involved side up the patient's involved leg is passively flexed, adducted, and internally rotated.

Positive test is when the patient reports pain reproduced at the region of the piriformis.

Evidence[edit | edit source]

Provide the evidence for this technique here

A study was performed by Fishman et al. that determine the sensitivity and specificity of the piriformis test.

Sensitivity = .882     -LR = .14

Specificity = .832    +LR = 5.2
