Indications

Sacroiliac Motion Palpation test, also known as Gillette’s Test is used to determine if there is a possibility of sacroiliac or public joint sprain, or pelvic fracture. The exam can also indicate hyper-mobility or hypo-mobility of SI joint.

Procedure

Patient Standing, examination in 2 parts:
  1. Examiner palpates the PSIS & S2 tubercle (spinous process) then instructs the patient to slowly march in place, examiner observes motion.
  2. Examiner then repeats manoeuvre palpating the PIIS and sacral apex and compares bilaterally.

Interpretation

Pain Sacroiliac or pubic joint sprain, pelvic fracture.
Abnormal motion hyper-mobility or hypo-mobility of sacroiliac joint

Clinical Notes

Occasionally patients will have a repeatable ‘click’ or ‘snap’ with this manoeuvre, this finding is most likely due to a tendon snapping over a tubercle.

Clinician’s Option – Other SI Motion Manoeuvres
  1. Patient prone, examiner applies force over the sacral base and ischial tuberosity to check SI flexion. Test repeated with force applied over the sacral apex & PSIS to check SI extension
  2. Patient seated, examiner palpates medial edge of PSIS & instructs patient to adduct & abduct thighs (flare test).
