The Gillet Test for SI-Joint Dysfunction

The Gillet Test is also known under the names of Marching Test or Sacral Fixation Test. The test was designed to detect sacroiliac joint dysfunction, which is defined as a sacroiliac joint that is “blocked” and thus not moving. Like many other palpation tests, the Gillet test has a low reliability with a kappa value of 0.22 [according to Dreyfuss et al. in the year 1996]. The same authors report a sensitivity of 43% and a specificity of 68%. So altogether, the value of this test is questionable in practice. To perform the test position yourself behind the patient and palpate both posterior superior iliac spines which should be at the same level as the spinous process of SII. Now to test the right SI joint palpate SII with your left hand and the right hand stays on the PSIS. Now ask your patient to flex his hip to 90 degrees In a normal SI joint the PSIS will drop below SII. In a dysfunctional SI which is blocked or you will see that the PSIS will not drop or move only.
