Answer 1

Locomotion Movement

- eg walking

Question 2

Answer 2

Stance Phase and Swing Phase

Question 3

What is the other name for the stance phase?

Answer 3

Heel strike

Question 4

What is the other name for the swing phase?

Answer 4

toe off

Question 5

What % does the stance phase use?

Answer 5

60%

Question 6

What % does the swing phase use?

Answer 6

40%

Question 7

In the early stance phase what is the movement at the hip, knee and ankle?

Answer 7

Hip: flexion to extension
Knee: extension
Ankle: dorsiflexion but moving into plantarflexion

Question 8

Wha muscle(s) is concentric (contracting) at the early stance phase at the hip?

Answer 8

Gluteus maximus, hamstring

Question 9

What muscle(s) is eccentric (lengthening) at the early stance phase at the hip?

Answer 9

iliopsoas

Question 10

Early stance muscles concentric at knee and ankle

Answer 10

Knee: isometric= Quadriceps femoris and hamstings, gastrocnemius
Ankle: triceps surae (posterior)
- eccentric (tibialis anterior)

Question 11

Mid Stance muscles at hip, knee, ankle

Answer 11

HIp: concentric = gluteus maximus, hamsting
Eccentric = iliopsoas
Knee: hamstring, gastrocnemius
Ankle: triceps surae

Question 12

Late stance movements

Answer 12

Hip: same - extension
Knee: moved from slight flexion into extension
Ankle in full plantar flexion

Question 13

Late stance muscles

Answer 13

Same all through stance phase
Hip: Concentric = gluteus maximus, hamstings. (eccentric = ilopsoas)
Knee: Quadriceps femoris
Ankle: Same = triceps surae

Question 14

What does concentric mean?

Answer 14

Contracting, agonist muscle

Question 15

What does Eccentric mean?

Answer 15

Lengthening, Antagonist muscle

Question 16

Early swing movement at Hip, knee, Ankle?

Answer 16

Hip: moving into flexion
Knee: in flexion
Ankle: dorsiflexion

Question 17

Muscles at the early swing phase

Answer 17

Hip: concentric- iliopsoas, eccentric: hamstring, gastrocnemius
Knee: Concentric- hamstring, gastrocnemius
Ankle: concentric- tibialis anterior

Question 18

What is the role of the hamstring lengthen at the hip

Answer 18

Controlling the rate that the leg moves at

Question 19

Does the mid swing phase use the same muscles and movement as the early swing?

Answer 19

Yes

Question 20

Late swing muslces

Answer 20

Hip: concentric= iliopsoas. (eccentric= gluteus maximus, hamstring)
Knee: concentric= quadriceps femoris (anterior)
ankle concentric = tibialis anterior (isometric= ticeps surae)

Question 21

Late swing movement

Answer 21

Hip: further into flexion
Knee: In flexion but moving into extension
Ankle: dorsiflexion (most stable for heel strike
