Position the patient lying on the table in a supine position, placing a bolster or towel under their ankles. With a goniometer, measure for normal or hyperextension range of motion at the knee. Place the fulcrum at the knee joint line with the proximal end aligned with the greater trochanter and the distal end towards the lateral malleolus. Instruct the patient to actively extend their knee and record the reading in degrees. Noting that 0o is neutral; therefore a negative number means limited range of motion.
