GILLET
TEST
• Test positioning
The client stands while the therapist palpates the posterior superior iliac spine bilaterally.
• Action
The client flexes one hip and brings the knee to the chest while the therapist maintains palpation to each PSIS and assesses overall sacroiliac movement.
• Positive finding
A positive sign is noted if the PSIS on the ipsilateral side of the knee being flexed does not move or moves minimally in the interior direction.
• Special considerations & comments
The PSIS on the side of the hip being flexed should move slightly anteriorly during active hip flexion.
