Add the impairment values contributed by forward flexion and backwardextension. Their sum represents the impairment of the lower extremitycontributed by abnormal forward flexion and backward extension of thehip.AnkylosisPlace the goniometer base as if measuring the neutral position (Figure 72).Measure the deviation from neutral position with the goniometer arm andrecord the reading.Consult the Ankylosis Section of Table 38 to determine the impairment ofthe lower extremity.Example: A hip joint with ankylosis at 20° backward extension isequivalent to 90% impairment of the lower extremity.Hip joint-Abduction and Adduction Abnormal MotionPlace the patient on a table in the neutral position (Figure 74) with theopposite hip flexed and held to lock the pelvis. The leg to be tested isextended in a relaxed position.Center the goniometer over the hip joint (Figure 74). Record thegoniometer reading. Consider 90° as the neutral point.Abduction: With the patient abducting the thigh as far as possible (Figure75), follow the range of motion with the goniometer arm. Record theangle that subtends the arc of motion.Adduction: Starting from the neutral position with the patient swinging theleg across the body as far as possible (Figure 76), follow the range ofmotion with the goniometer arm. Record the angle that subtends the arcof motion.
