The range of motion to be measured is the range of active motion. The medical assessor should be satisfied that the claimant is making an appropriate effort to demonstrate the maximal range and that the measurements are consistent (that is, several repetitions). The normal ranges of motion of individual joints in the musculoskeletal system are set out on the next page.

Peripheral vascular disease affecting lower and upper extremities is assessed under Table 1.4 and Table 1.5 (Chapter 1 ? The Cardiovascular System).

Part I

The Lower Extremities: Feet and Toes, Ankles, Knees and Hips

Part I ? Introduction

The impairments assessed for each region in the lower extremity are combined to obtain the overall impairment of the lower extremity for the individual extremity, subject to the notes accompanying the applicable tables, or any indication that combination is not permitted.

A WPI rating for one lower extremity may be combined with a WPI rating for the other lower extremity, except in the case of WPI ratings under Table 9.7: Lower Extremity Function, where the notes accompanying Table 9.7 are to be followed.

WPI ratings from Table 9.1: Feet and Toes, Table 9.2: Ankles, Table 9.3: Knees and Table 9.4: Hips must not be combined with a WPI rating under Table 9.7 if they assess the same condition in the same lower extremity.

Where a condition cannot be assessed under one of Tables 9.1, 9.2, 9.3 and 9.4, an assessment may be made under the provisions of the edition of the American Medical Association?s Guides to the Evaluation of Permanent Impairment current at the date of the assessment.

If the medical assessor feels that the impairment is not adequately assessed using one of Tables 9.1, 9.2, 9.3 and 9.4, and the condition does not cause a reduction in the range of motion of a joint but there is significant interference with gait, the medical assessor should consider the effect of the injury on gait and determine the WPI rating using Table 9.7.

If permanent, conditions such as sesamoiditis, plantar fasciitis, plantar tendonitis, and pes planus, should be assessed under Table 9.7.

All ankylosis assessments from Tables 9.1, 9.2, 9.3 and 9.4 are alternative assessments to those for abnormal motion of the individual joints.

The maximum WPI rating for a single lower extremity in Tables 9.1, 9.2, 9.3 and 9.4 is 40%, including combined WPI ratings.

Steps in Calculating Lower Extremity Impairment

Step 1	Add abnormal motion/ankylosis impairment values within an individual joint.
Step 2	Combine abnormal motion/ankylosis impairment values for different joints in the toes.
Step 3	Add impairment values obtained for each individual toe and combine this value with the impairment values for other joints in the foot to obtain the total abnormal motion/ankylosis impairment assessment for a foot.
Step 4	Combine with abnormal motion/ankylosis impairment assessments for different regions in the lower extremity (that is, knee(s), hip(s)).
Step 5	Combine with impairment values for peripheral nerve injuries.
Step 6	Combine with impairment values for amputation.

9.1 Feet and Toes

Table 9.1 assesses impairments to range of motion of the feet and toes, including ankylosis of one or more joints. The maximum WPI rating under Table 9.1 is 2% for impairment of two or more of the 2^nd, 3^rd, 4^th and 5^th toes of one foot.

In the case of toes, the ankylosis referred to in Table 9.1 is that of the metatarso-phalangeal joint.

Ankylosis of the interphalangeal joints of the 2^nd, 3^rd, 4^th or 5^th toe attracts a WPI rating of 0. The position of function is the neutral position.

9.2 Ankles

Table 9.2 assesses impairments to range of motion and deformity of the ankle, as well as ankylosis. Ankle deformity with movement is assessed separately from ankylosis.

Ankylosis in the optimal position is equivalent to a WPI of 4 %. The optimal position is the neutral position without flexion, extension, varus or valgus. This is the base level of ankylosis impairment in the ankle.

When ankylosis is not in the optimal position, add the relevant WPI ratings from Table 9.2 for ankylosis in each direction. Then add the base figure of 4% WPI for ankylosis in the optimal position.

The maximum WPI rating for multiple impairments of the ankle and hindfoot is 25% WPI. If the total WPI rating obtained by adding different WPI ratings is higher than 25% WPI, then the final WPI rating for the ankle is 25%.

Table 9.2: Ankles

% WPI	Criteria (ONE required ? different conditions may be assessed separately ? but see notes on ankylosis above)

9.3 Knees

Table 9.3 assesses impairments to range of motion and deformity of the knee, as well as ankylosis. Knee deformity with movement is assessed separately from ankylosis. ?Deformity? is measured by the femoral-tibial angle: 3? -10? valgus is considered normal.

Ankylosis in the optimal position is equivalent to 27% WPI. The optimal position is 10? -15? of flexion with good alignment. This is the base level of ankylosis impairment in the knee. When ankylosis is not in the optimal position, add the relevant WPI ratings from Table 9.3 for ankylosis in each direction. Then add the base figure of 27% WPI for ankylosis in the optimal position.

The maximum WPI rating for multiple impairments of the knee is 40% WPI. If the total WPI rating obtained by adding different WPI ratings is over 40%, then the final WPI rating for the knee is 40%.

9.4 Hips

Table 9.4 assesses impairments of range of motion and deformity of the hip, as well as ankylosis. Hip deformity with movement is assessed separately from ankylosis.

Ankylosis in the optimal position is 20% WPI. The optimal position is 25? -40? of flexion with neutral rotation, abduction and adduction. This is the base level of ankylosis impairment in the hip. When ankylosis is not in the optimal position, add the relevant WPI ratings from Table 9.4 for ankylosis in each direction. Then add the base figure of 20% WPI for ankylosis in the optimal position.

The maximum WPI rating for multiple impairments of the hip is 40%. If the total WPI rating obtained by adding different WPI ratings is over 40%, then the final WPI rating for the hip is 40%.

9.7 Lower Extremity Function

Table 9.7 should only be used to assess impairment from objectively identified orthopaedic or neurological conditions arising in and affecting the lower extremities. It may not be used to assess impairment from conditions manifesting principally as pain with no clinically demonstrable lower extremity pathology.

A secondary dysfunction consequent to disuse is only assessable under Table 9.7 if this dysfunction is permanent (that is, not likely to improve as a result of surgery, medication or other rehabilitative treatment) and there are objective clinical findings that can be validly assessed using other tables in Chapter 9, Part 1 ? The Lower Extremities.

If permanent, conditions such as sesamoiditis, plantar fasciitis, plantar tendonitis, and pes planus, should be assessed under Table 9.7.

Table 9.7 must not be used in cases involving amputations.

A single assessment only may be made under Table 9.7, irrespective of whether one or two extremities are affected by the injury. The impairment assessed is of overall lower extremity function, rather than that of individual extremities.

Before using Table 9.7 the medical assessor should check the instructions (see Part I ? Introduction) preceding the specific joint impairment tables (Tables 9.1?9.4) and use Table 9.7 strictly in accordance with those instructions.

Where one limb only is affected, regardless of the number of impairments found in that limb, the limb should be assessed using the relevant Tables other than 9.7 and all impairments combined using the Combined Values Table. The combined impairment rating should then be compared to the rating taken from the relevant row in Table 9.7 and the higher rating obtained from the two methods chosen.

Where both limbs are affected, each limb should be assessed using the relevant Tables other than 9.7 and all impairments in both limbs combined using the Combined Values Table. The combined impairment rating should then be compared to the rating taken from the relevant row in Table 9.7 and the higher rating obtained from the two methods chosen.

Table 9.7 may be used to assess lower extremity impairment arising as a result of spinal cord damage. Observe the special procedure set out in the introduction to Part III of this Chapter. However, Table 9.7 is not to be used to assess lower extremity impairment arising as a result of nerve root compression, or other neurological sequelae of other spinal conditions. These should be assessed under:

Table 9.6.1, Table 9.6.2a or Table 9.6.2b (tables dealing with Spinal Nerve Root Impairments and Peripheral Nerve Injuries Affecting the Lower Extremities); or
Table 9.15: Cervical Spine; or
Table 9.16: Thoracic Spine; or
Table 9.17: Lumbar Spine.

To fulfil the requirements of a WPI rating in Table 9.7, there must be one major criterion, and at least two minor criteria, present (where minor criteria are listed).

?Manifest difficulty? is difficulty (such as stumbling, or an altered gait) evident to the medical assessor. The difficulty must be tested clinically: history alone cannot be relied upon in the assessment.
