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
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
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
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
Measurements
True leg length Measure from A.S.I.S
to inferior border of medial malleolus
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.
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.
MovementExpected 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
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°)
Movements
Abduction:
• Stabilise pelvis and hold ankle with other hand
• Abduct and note ROM (45°)
Adduction:
• As above and note ROM (30°)
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
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
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.
