SQUISH
TEST
• Test positioning
The client lies supine on the table while the therapist places a hand on each of the iliac crests and the anterior superior iliac spines of the client.
• Action
The therapist compresses downward and inward at a 45-degree angle along the iliac crest and anterior superior iliac spine bilaterally.
• Positive finding
Subjective complaints of pain are noted as positive findings and may be found anteriorly or posteriorly.
• Special considerations & comments
This test assesses the stability of the posterior sacroiliac ligaments but also directly applies compressive forces to the anterior sacroiliac joint.
Thus, the location of pain should be noted and correlated with any additional findings.
The Squish Test is based on the work of Dr. James Cyriax and Dr. Pierre Gillet in assessing sacroiliac joint dysfunction, particularly in understanding sacral instability and the mechanical loading of the sacroiliac joint.
