Q

Move?

A
  1. active
  2. passive
    Note: Usually passive unless there is a specific reason:
    - Need to assess the painless / painful range of motion
    - Need to assess muscle power

Q

What is the Thomas test?

A

a test used to measure the flexibility of the hip flexor muscles
- its a test for hip flexor tightness

Q

Describe the Thomas Test?

A
  1. patient is lying supine on a flat hard surface
  2. one knee is flexed and being held at the chest at the point where the lumbar spine is felt to flex
  3. the clinician assesses whether the thigh of the extended leg maintains full contact with the surface of the bed

Q

What does a positive Thomas Test mean?

A

indicates a decrease in flexibility in the rectus femoris or iliopsoas muscles or both
- in normal hip extension is only possible up to the neutral position 0 degrees (thigh lies on the table) and further flexion can tilt the pelvis further upright

Q

When should you take precaution when doing the Thomas test and how do you solve the problem?

A

Precaution = when knee has fixed flexion deformity
Solution = keep knee outside edge of couch

17
Q

Thomas test in neonates and young children?

A

Positive Thomas test in neonates and young children is normal

18
Q

What is the Trendelenburgh test?

A
  • You are testing the hip the patient is standing on
  • Normally the pelvis tilts down on the weight-bearing hip
  • This is performed by the hip abductors
19
Q

What is the positive Trendelenburgh test?

A
  • the pelvis on the non weight-bearing hip tilts down
  • the trunk has to tilt to the weight-bearing side
20
Q

What is the Trendelenburgh sign?

A

loss of abductor function (gluteus medius and minimus) causes the pelvis to tilt down when supporting the body on the affected side
- indicates damage to the superior gluteal nerve

21
Q

Causes of positive trendelenburgh?

A
  1. Weak hip abductors
    - paralyzed / wasted
  2. Mechanically inefficient hip abductors
    - distance between origin & insertion reduced
    e.g. coxa vara
  3. Unstable pivot of motion:
    - hip subluxation / dislocation
  4. Inhibited hip abductors: painful to move
    - trauma (sprains) / infection / irritation / tumor
  5. Reduced range of motion:
    hip incongruent / stiffness / OA
22
Q

What is the Galeazzi test?

A

used to assess for hip dislocation primarily in order to test for developmental dysplasia of the hip
Note: also known as Allis sign

23
Q

How do you perform a Galeazzi test?

A

flexing an infants knees when they are lying down so that the feet touch the surface and the ankles touch the buttocks
- both heels have to be at the same level

24
Q

What is a positive Galeazzi sign?

A

an inequality in the height of the knees
- caused by hip dislocation or congenital femoral shortening

25
Q

What is leg length assessment?

A

measuring the leg lenghth
1. apparent length
2. true length

26
Q

What is apparent length?

A

can be measured from the umbilicus to the medial malleoli of the ankle
- affected by pelvic tilt

27
Q

What is true length?

A

length from the anterior superior iliac spine to the medial malleolus
- not affected by pelvic tilt

28
Q

Phases of the normal gait cycle?

A
  1. stance phase (60%)
  2. swing phase (40%)
29
Q

Describe the stance phase?

A
  1. Heel strike
  2. Foot flat - mid-stance
  3. Push off
30
Q

Describe the swing phase?

A
  1. Acceleration
  2. Mid-swing
  3. Deceleration
31
Q

Normal gait?

A

Normal stance and swing phases

32
Q

Antalgic gait?

A

Painful to weight-bear
– short stance phase

33
Q

Lurch gait?

A

Shortening – painless limping – normal stance period

34
Q

Circumduction gait?

A

Stiff hip
– motion of pelvis compensates

35
Q

High step gait?

A

Foot drop
– more hip & knee flexion needed to free toes from ground

36
Q

Tip toe gait?

A

Heel off the ground
