16
Q

What is the torque demand at the ankle joint during the loading response phase?

A

Plantarflexion torque forces foot to floor then diminishes

17
Q

What is the muscle action at the ankle joint during the loading response phase?

A

Pre Tibialis contract eccentrically

Soleus and gastroc act to control tibial advancement

18
Q

What is the functional significance at the ankle joint during the loading response phase?

A

Heel rocker action created

Momentum carried forward

Knee flexion initiated

19
Q

A

15° of flexion

20
Q

What is the torque demand at the knee joint during the loading response phase?

A

Moderate intensity flexion torque

21
Q

What is the muscle action at the knee joint during the loading response phase?

A

Eccentric quad activity

Diminishing hamstring activity

22
Q

What is the functional significance at the knee joint during the loading response phase?

Shock absorbed

Limb stability maintained

23
Q

What is the ROM at the hip joint during the loading response phase?

A

20° of flexion

24
Q

What is the torque demand at the hip joint during the loading response phase?

A

High intensity flexion torque

Adduction torque begins

25
Q

What is the muscle action at the hip joint during the loading response phase?

A

Hip extensors and abductors active

26
Q

What is the functional significance at the hip joint during the loading response phase?

A

Hip joint, pelvis, and trunk stabilized in Sagittal and frontal planes

27
Q

What is happening with the pelvis in the loading response phase?

A

5° of forward rotation in horizontal plane

28
Q

What does the heel rocker action provide?

A

Forward progression of the entire stance limb

29
Q

What is the ROM at the subtalar joint during the loading response phase?

A

Calcaneus everts 5°

Subtalar joint pronates

30
Q

What is the torque demand at the subtalar joint during the loading response phase?

A

Eversion torque

31
Q

What is the muscle action at the subtalar joint during the loading response phase?

A

Anterior and posterior Tibialis muscles contract eccentrically

32
Q

What is the functional significance at the subtalar joint during the loading response phase?

A

Assists shock absorption

Induces IR of tibia which reduces rotatory stress on ankle
