Stork test

Last revised by David Luong on 6 Feb 2022

The Stork test (also known as the Gillet test) is a clinical test used to assess the movement (intrapelvic motion) of the sacroiliac joint between the innominate bone and sacrum. It can be useful in evaluating suspected sacroiliac joint pathology / dysfunction.

It involves placing the examiner's thumb medial to the posterior superior iliac spine and asking the subject to pull the hip of the side being palpated into 90° or more of hip flexion.
