43. Leg Length Tests   True Leg Length Discrepancy  Measure ASIS to medial malleolus  Positive = 1-1.5 cm   Apparent (Functional) Leg Length  Umbilicus to Medial malleolus

44. Trendelenberg Test   Pt Position = standing on one leg with WB leg being the involved limb   Positive = pelvis on opposite side drops   Indications = weak Gluteua medius

45. Kendall Test   Pt Position = supine with knees bent over the table   Evaluation  One hand under lordotic curve  Passively flex hip to chest  Allow opposite leg to rest on table   Positive = knee move into extension or leg rises off table

46. Thomas Test   Pt Position = supine with both leg on table   Evaluation  One hand under lumbar region  Passively flex one leg to chest   Positive = straight leg raises off table  Increased lordotic curve

47. Measurements   True leg length   Measure from A.S.I.S to inferior border of medial malleolus

48. Measurements   True Shortening   In true shortening the affected limb is physically shorter than the other and this may be caused by pathology proximal or distal to the trochanters.   True shortening from causes distal to the trochanters most frequently results from previous fractures of the femur or tibia or growth disturbance (e.g. from polio or epiphyseal trauma). Proximal to the trochanters causes include femoral neck fractures, OA and hip dislocation.

49. Measurements   Apparent leg length   Measure from tip of xiphoid process to inferior border of medial malleolus   Apparent Shortening   In apparent shortening the limb is not altered in length, but appears shortened. This may be as a result of an adduction contracture of the hip joint, which has to be compensated for by tilting of the pelvis, or SIJ pathology causing pelvic rotation.

50. Movement Expected Range of Movement   Flexion:0-130 Degrees   Abduction:0-45 Degrees   Adduction:0-30 Degrees   MR:0-45 Degrees   LR:0-60 Degrees   Extension:0-20 Degrees

51. Movements   Thomas’ test: Place your left hand in hollow of lumbar spine Flex hip and knee of unaffected side Look to see if hip of the affected side lifts from bed   Flexion: Flex hip and knee of affected side and note ROM (130°)

52. Movements   Abduction: Stabilise pelvis and hold ankle with other hand Abduct and note ROM (45°)   Adduction: As above and note ROM (30°)

53. Movements   Rotation: Flex hip and knee to 90 degrees, externally and internally rotate Note ROM (45°)   Abnormal Movement (telescoping): Alternately push and pull leg along its long axis – demonstrates marked instability

54. Trendelenberg Test   Used to assess the ability of the hip abductors to stabilise the pelvis on the femur.   A positive test demonstrates that the hip abductors are not functioning.   Causes: Disturbance in pivotal mechanism – dislocation or subluxation of hip, shortening of femoral neck Weakness of the hip abductors e.g. myopathy, neuropathy

55. Trendelenberg Test   The test is performed with the patients back to the examiner. The model stands on the normal leg and flexes the knee of the other leg to a right angle.   The pelvis should remain level or tilt slightly upwards on the unsupported side.   The model then stands on the affected leg and flexes the knee of the other leg.   If the pelvis tilts downwards on the unsupported side, then this confirms a positive Trendelenberg sign.
