ASIS Compression Test

You are here:

Used to determine the presence of a sacroiliac and/or iliosacral dysfunction​

With the patient seated laying supine, physician will find the anterior superior iliac spines (ASIS), and physician will place their palm on top of the ASIS on both sides.

The physician will then exert a posterior compressive force on each of the ASIS, one at a time, alternating sides.

Test is considered to be positive on the side that the ASIS is more resistant to the compressive force. This allows the physician to determine that there is a dysfunction on the side of the positive test.

A note to remember:

The ASIS compression test is only a test of lateralization, on its own, it does NOT provide a diagnosis.
