18
Q

Which muscle performs sagittal plane function

A

Adductor Longus

19
Q

Hip muscle action of Adductor Longus

A

Hip Extension and knee flexion

20
Q

There are NO PRIMARY Internal Rotators of the Hip : True or False

A

TRUE

21
Q

Secondary internal rotators of the hip are:

A

Anterior fibers of glutues medius/ minimus
Tensor Fascia Lata
Adductor longus, brevis, pectineus and medial hamstrings

22
Q

Name the hip extensor’s prime mover

A

Gluteus Maximus

23
Q

Concentric activation of hip extension does what?

A

Hip Extensionnn :)

24
Q

Concentric Activation (hip extensor) examples:

A

Sitting position to a standing position
-walking up the stairs
-jumping/ running

25
Q

Femoral on pelvic- what position should you be in?

A

Lying on back/ lift leg

26
Q

Eccentric Activation of Hip Extensor Muscles:
what position?

A

Going from a standing position to a sitting position
(de-accelerator/ “break”)

27
Q

Hip Extensor = Posterior Pelvic Tilt.
True or False?

A

TRUEEE

28
Q

How to Stretch Hip Extensors

A

Posterior Pelvic Tilt or Stand Neutral

29
Q

True or false:
Hip Abduction is NOT a common action

A

TRUEEE

30
Q

Primary Hip Abductors

A

Gluteus Medius & Gluteus Minimus

31
Q

Secondary hip abductors

A

Piriformis
TFL
Sartorius

32
Q

What is Abductors main function?

A

control of frontal plane pelvic on femoral stability during gait

33
Q

What is an example of abductors main function?

A

Walking and in phase of gait where body weight is on a single leg. If right leg is off ground (unsupported) and left leg is supported (on ground)—> body will then move naturally/ gravity to the right side = unsupported side

34
Q

what is primary source of stability in the hip

A

control frontal plane stability

35
Q

How does Hip Abductor effect Moment Arm and Mobility

A

Large Moment Arm= decreased mobility
- more for stability of pelvic and abdominal region

36
Q

**If a person lifts their leg off the ground, and pelvis drops to the left side as well, this indicates weakness of the ________ hip abductors

A

RIGHT

37
Q

*** If a person lifts their right leg off the ground, the pelvis drops to the right side, this indicates Weakness of the ______ hip abductors

A

LEFT (Gluteus Medius)

38
Q

An example of Hip Abductor Torque:

A

Arthritis- Left Hip = Cane on Right Hand

39
Q

The 6 External Rotators:

A

3.) Superior Gemellus
4.) Quadratus Femoris
5.) Gluteus Maximus
6.) Sartorius

40
Q

Primary external rotator:

A

Piriformis
