Ely test protocol involves what action?

• A. With the patient prone and pelvis stabilised, the examiner passively flexes the knee while observing for anterior pelvic tilt.
• B. With the patient standing, the examiner flexes the hip actively.
• C. With the patient supine, the knee is extended passively.
• D. The patient performs active knee flexion while the pelvis is free to move.

Answer: (A)

The action being tested is assessing rectus femoris length by watching for compensatory pelvic movement during knee flexion. In this protocol, the patient lies prone and the pelvis is stabilized. The examiner passively flexes the knee toward the buttock while observing the pelvis. If there is an anterior tilt of the pelvis as the knee is flexed, it indicates the rectus femoris is tight because this muscle crosses both the hip and knee joints and tends to pull the hip into flexion when the knee is bent. If the pelvis stays still and the knee can flex without this tilt, the rectus femoris length is normal.
