Assessment of the Sacroiliac Joint

(The Stork Test | Leg Length Difference | Ilia Rotation)

Ilia Rotation

• With the patient lying on their back a modesty towel is placed over the pelvic area.
• The towel not only provides the patient with privacy but also prevents the therapists eyes from being distracted by uneven images created by clothing patterns.
• The therapist stands one side of the couch and must lean over the patient and ensure the dominant eye is looking along the midline of the patient whilst the other eye is closed. This ensures your angle of view is central and not distorted.
• The therapist then places one thumb on each ASIS and compares their location by looking along the midline between both ASIS, which should indicate they are level.
• If one is higher than another this may indicate a pelvic rotation or shunt although bone shapes can vary in individuals and it is common to see differences in ilia shapes between the right and left side. This can lead to confusion regarding diagnosis but it should be remembered that tests are not definitive and are only a method of gathering information to assist with a diagnosis. The more tests you use then the more information you have.
