18
Q

What are the stabilising features of the hip?

A
  • Joint capsule- iliofemoral, pubofemoral and ischiofemoral ligaments.
  • Acetabular labrum
  • muscles which run parallel to the femoral head such as iliopsoas, short lateral rotators (names)
  • bursae and fat pads
  • Congruency between femoral head and acetabulum
19
Q

What are the features of a synovial joint?

A

Synovial joints are freely mobile joints which are usually limited in movement by a joint capsule, ligaments and muscles surrounding the joint. The articular surfaces are covered with hyaline cartilage which allows minimal friction between the joint surfaces. Synovial membranes are present and they lubricate, nourish and reduce friction between the articular surface cartilage. Bursae can be present and can communicate directly with the joint space.

20
Q

Define what happens in medial rotation? Does it matter if the knee is bent or straight? If so why?

A

Medial rotation is the action of the thigh moving inwards toward the midline.

If the leg is straight the foot goes in the direction of the femur. If the knee is bent the foot goes in the opposite direction to the femur

21
Q

Identify and explain which other structures may be under stretch with the FABER test.

A
22
Q

What is the end feel of Abduction of the hip?

A

Firm end feel due to the capsular and ligament limitations

23
Q

What structures are put under stretch in lateral rotation of the hip?

A

Gluteus Medius, Gluteus Minimus and tensor fascia lata (main medial rotators)

Pubofemoral and iliofemoral ligaments

24
Q

What is the close packed position of the hip?

A

Hip extension, medial rotation and Abduction

25
Q

How does this position relate to functional activities?

A

It is the maximal congruency in the joint and the maximal joint stability. Functionally, it gives a position of stability in stance for swing phase of other leg.

26
Q

Identify and explain normal and abnormal findings of Obers test and how this can contribute to your reasoning

A

The leg being tested should drop below the level of the bed. If the testing leg doesn’t drop then that is a positive test with indicates a tight TFL and ITB

27
Q

State the health and safety principles that the therapist needs to ensure during passive movements of the hip.

A
  • Safe bed height, brakes on before patient gets on, clean
    • Hand hygiene
    • Consent
    • Therapist positioning
    • Communicate with the patient and check their position
    • Soft hands, move limb slowly to end of range of motion and gently return to anatomical position
28
Q

What is the normal range of movement of hip extension?

A

AROM- 0-20 degrees of movement

29
Q

What is an accessory movement and why should they be tested?

A

They are joint glides that occur during normal movement that an individual cannot perform themselves.

30
Q

Identify and explain the end feel concept of hip flexion and how this can contribute to your reasoning

A

Hip flexion is a soft feel due to the quadriceps ROM being stopped by soft tissue of the abdomen. Hard end feel may indicate bone on bone contact, excessive movement may indicate laxity in the hip ligaments or muscles

31
Q

Identify and explain how shortness of semitendinosus. could affect active and passive movements at both the hip and the knee.

A
32
Q

Identify and explain which structures limit normal movement of hip medial rotation

A
33
Q

Identify and explain the muscles involved in hip adduction

A
34
Q

Identify and explain the role of the hip abductors In walking.

A
35
Q

Identify and explain how shortness of gracilis could affect active and passive movements at the hip.

A
36
Q

What is the function of the Acetabular labrum

A

deepens the acetabulum by raising the rim of the acetabulum slightly, thereby increasing the acetabular articular area

37
Q

What are the differences between the Shoulder joint and Hip joint

A
