From Free net encyclopedia

Stork Test
The Sacroiliac joint dysfunction (SI Joint Dysfunction) can be tested with the Stork Test.
1) With the patient standing and the examiner sitting behind, the examiner's left thumb is placed over the most posterior portion of the left posterior superior iliac spine (PSIS) and the right thumb overlying the midline of the sacrum at the same level.
2) Examiner asks the patient to flew the left hip and knee to a minimum of 90 degrees of the hip flexion. Imagine making an "L" with the leg and thigh.
3) A negative test finds the left thumb on the posterior superior iliac spine (PSIS) moving caudad (towards the tail) in relation to the right thumb on the sacrum.
4) The thumb placements are reversed, and the patient is asked to raise the right leg in similar fashion.
5) A positive finding occurs when the thumb on the PSIS moves cephalad (towards the head) in relation to the thumb on the sacrum.
6) The findings of this test are correlated with those of the standing flexion test. The Stork test is more specific for SI joint Restriction.
7) If the patient has difficulty standing on one foot to perform the test, proprioceptive sensory motor balance deficit should be further evaluated.
