Place the goniometer base as if measuring the neutral position (Figure 67).Measure the deviation from neutral position with the goniometer armextending along the lower leg and record the reading.Consult the Ankylosis Section of Table 35 to determine the impairment ofthe lower extremity.Example: A knee joint with ankylosis at 20° flexion is equivalent to 60%impairment of the lower extremity.Table 36 lists impairment ratings for other disorders of the knee.3.2d Hip JointForward FlexionAbnormal MotionPlace the patient in the neutral position (Figure 69) with the opposite hipflexed and held to lock the pelvis. The leg to be tested is extended in arelaxed position.Place the goniometer next to the hip joint (Figure 70). Record thegoniometer reading. With the patient flexing the hip to be tested as far aspossible (Figure 71), follow the range of motion with the goniometer armuntil the superior iliac spine begins to move. Record the angle thatsubtends the arc of motion.Consult the Abnormal Motion Section of Table 37 to determine theimpairment of the lower extremity.Example: 20° forward flexion from neutral position (0°) is equivalent to14% impairment of the lower extremity.
