Q

The external moment of the hip during initial swing is to (flexion/extension) even though there is no GRF and this is because if I get into a good rhythm with walking, my hip flexion is from (momentum/COP), it is from me harnessing all of my bodies movements and I don’t need to use all of my hip flexors to walk. Remember, proper walking is the least amount of energy used, it is the way you want to walk.

Q

The external moment of the knee during initial contact is (flexion/extension) and the muscle activity will come from both the knee (flexors and extensors/abductors and adductors). When you flex your knee and you land, you will have a flexion moment. So the knee extensors will be engaged to avoid the (flexion/extension) torque. Your hip extensors are also knee flexors, so if my hip extensors aid in hip extension, they are going to be turned on at the hip. You can’t just turn on one part of the hip and keep the other part off so that is how things link together. Think of the co contractions between the hamstrings and quads during squats, same thing applies here.

Q

The external moment of the knee during mid stance is (flexion/extension) to (flexion/extension) and the muscle activity will come from the knee (flexors/extensors).

A

flexion to extension; extensors

28
Q

If someone has a weak quad and I start to move my body forward, the COM will be (anterior/posterior) to my knee and my knee (flexors/extensors) will be controlling my knee extension as I go from a flexed knee to an extended knee. If they don’t have great control, what ends up happening is the person will get what is called an extension thrust and they will go backwards. The knee will snap back into hyper extension

A

anterior; extensors

29
Q

In the sagittal plane during terminal stance the knee is in full )(flexion/extension) and its’ function is stability and to increase the step length.

A

A

extension; passive; gastrocnemius and popliteus

31
Q

If I had a knee flexion contracture the (mid/terminal) stance would mostly be affected because we have to get into full (flexion/extension) for proper terminal stance. If you can’t get your knee fully straight, I will never get the leg back far enough in the (mid/terminal) stance.

A

flexion; flexors

36
Q

During initial swing your external moment continues to be knee (flexion/extension) because of (muscle activity/momentum). So the momentum is pulling your thigh forward and it keeps your knee bending into (flexion/extension). It is not muscle activity or GRF, it is due to momentum.

41
Q

In the sagittal plane during initial contact, the position of the ankle is in (neutral/plantar flexion) and its’ function is to begin the heel rocker and impact (acceleration/deceleration). So in this phase as you are falling forward and the initial contact reacting with the ground is (speeding me up/slowing me down).

A

neutral; deceleration; slowing me down

42
Q

The external moment of the ankle during initial contact is (plantar/dorsi) flexion and the muscle activity will come from the ankle (plantarflexors/dorsiflexors). The foot is in neutral in this phase and wants to (plantar/dorsi) flex, thereby the ankle activity will be from the ankle (plantarflexors/dorsiflexors) trying to resist that fall.

A

plantar; dorsiflexors; plantar; dorsiflexors

43
Q

If you had a peripheral nerve injury or even a lumbar root issue, you can have a drop foot or foot slap occur with weakness of the (dorsiflexors/plantarflexors) because the (dorsiflexors/plantarflexors) aren’t able to slowly and eccentrically (dorsiflex/plantarflex) the foot. They lose control and there is a loud slap.

A

dorsiflexors; dorsiflexors; plantarflex

44
Q

The ankle dorsiflexors are (active/not active) during the swing phase to work to clear your toes from the ground, but they are the most active during (initial swing/initial contact) because they are supporting the body weight in this phase.

A

active; initial contact

45
Q

When you heel walk your weight is being supported by the ankle (dorsiflexors/plantarflexors) and the force is pulling your foot down on the ground.

A

dorsiflexors

46
Q

In the sagittal plane during loading response, the position of the ankle is in _ degrees of (dorsi/plantar) flexion and its’ function is to initiate progression and realigning the ankle axis.

A

48
Q

In the sagittal plane during mid stance, the position of the ankle goes from _ degrees of ____ flexion to _ degrees of ____ and its’ function is ankle rocker progression, shock absorption, and stability. If I am going from _ degrees of ____ flexion to _ degrees of ______ it is the (heel/ankle) rocker that is working because the tibia has to be advancing on the talus.

A

5; plantar; 5; dorsiflexion; 5; plantar; 5; dorsiflexion; ankle

49
Q

In the sagittal plane during mid stance, the shock absorption is coming from the foot in a (pronated/supinated) position.

A

pronated

50
Q

The external moment of the ankle during mid stance is (dorsiflexion/plantarflexion) and the muscle activity will come from the ankle (dorsi/plantar) flexors. As my tibia advances forward and my COM is now forward in front of my ankle the external moment will be ankle (dorsiflexion/plantarflexion) and I will be pulled into ankle (dorsiflexion/plantarflexion) and that is why the ankle (dorsi/plantar) flexors are working to resist that fall/movement that is occurring in this phase.

A

dorsiflexion; plantar; dorsiflexion; dorsiflexion; plantar

51
Q

In the sagittal plane during terminal stance, the position of the ankle is in _ degrees of (dorsi/plantar) flexion and the heel lifts at this point. The function in this stance is forefoot rocker progression that is aided by extension of the (MTP/Flexor hallucis longus).

A

10; dorsi; MTP

52
Q

In the sagittal plane during GAIT, the terminal stance is the phase where will you have the most amount of ankle (dorsiflexion/plantarflexion).

A

dorsiflexion

53
Q

The external moment of the ankle during terminal stance is (dorsi/plantar) flexion and the muscle activity will come from the ankle (dorsi/plantar) flexors and what other muscle?

A

dorsi; plantar and flexor hallucis longus

54
Q

If I went from 5 degrees of plantar flexion to 5 degrees of dorsiflexion and then to 10 degrees of dorsiflexion during the terminal stance, the plantar flexors would be working (concentrically/eccentrically) because they are getting (shorter/longer) and controlling dorsiflexion.

A

eccentrically; longer

55
Q

In the sagittal plane during the terminal stance of the ankle the flexor hallucis longus is now actively contracting as you go into extension to (speed up/slow down) the progression. It turns on because it is a toe (flexor/extensor) (remember in terminal stance the forefoot rocker progression is being aided by EXTENSION of the MTP) and you are moving into extension so this muscle turns on to provide a little support to not go into (flexion/extension) too quickly. So it is working (concentrically/eccentrically).

A

slow down; flexor; extension; eccentrically

56
Q

In the sagittal plane during pre-swing, we are kind of going on our toe and the position of the ankle is in _ degrees of (dorsi/plantar) flexion and its’ function is propulsion that begins knee (flexion/extension) and the max extension of the MTP initiates the (ankle/toe) rocker.

A

25; plantar; flexion; toe

57
Q

Max extension of the MTP is associated with the (forefoot/toe) rocker in the ____ phase.

A

toe; pre swing

58
Q

The external moment of the ankle during pre-swing is (dorsiflexion/plantarflexion) and the muscle activity will come from the ankle (dorsi/plantar) flexors that are working (concentrically/eccentrically) and the elastic recoil of the _____ tendon. If I am in plantar flexion and I am pushing off, the muscle group that is helping me the most at the ankle is the ankle (dorsi/plantar) flexors during push off.

A

dorsiflexion; plantar; concentrically; achilles; plantar

59
Q

Elastic recoil of the achilles tendon during pre-swing is like the (active/passive) tension that is forming through the gastrocnemius and soleus tendon in that position and is allowing the propulsion to take place. If I am walking it is important for me to keep a good pace in order to harness the (active/passive) tension.

A

passive; passive

61
Q

The external moment of the ankle in initial swing is (dorsi/plantar) flexion and the muscle activity will come from the (dorsiflexors/plantarflexors). You can feel this by standing with your leg up in the air and you will feel how gravity is pulling your foot down into (dorsi / plantar) flexion. And your muscle activity if you are going to clear the toes for lift off has to be (dorsi/plantar) flexion working (concentrically/eccentrically).

A

plantar; dorsiflexors; plantar; dorsi; concentrically
