Gillet's march test yields a positive result when there is what?

• A. Increased hip ROM
• B. No movement of PSIS
• C. Popping, clicking, and pain
• D. Pain in contralateral knee

Answer: (C)

The test assesses sacroiliac joint mobility and innominate rotation as the opposite leg is flexed. A positive result in this context is indicated by a popping or clicking sensation accompanied by pain during the maneuver, suggesting abnormal SI joint mechanics or irritation of the surrounding structures. In a normal run of the test, the movement should be felt as a smooth, relatively unobtrusive motion of the pelvis as the opposite thigh is brought toward the chest. The presence of a click or pain points toward SI joint dysfunction or instability. Increased hip range of motion or lack of PSIS movement would indicate different patterns of motion or other issues, while knee pain on the opposite side isn’t the expected primary sign of this test.
