Midstance & Terminal stance

Question 1

Name the Phase:

Critcal Events Present -

Ankle Kinematics -

Ankle Muscles activated -

Ankle Kinetics (joint moment) -

Answer 1

Midstance

Critcal Events Present - Controlled tibial advancement

Ankle Kinematics - dorsiflexion 5

Ankle Muscles activated - Gastroc Soleus to control advancement of tibia

Ankle Kinetics (joint moment) - GRF through joint (joint moment = 0)

Question 2

Name the Phase:

Critcal Events Present -

Knee Kinematics -

Knee Muscles activated -

Knee Kinetics (joint moment) -

Answer 2

Midstance

Critcal Events Present - Controlled Tibial Advancement

Knee Kinematics - Flexion 0-5

Knee Muscles activated - Passive structures behind the knee (quads turned off)

Knee Kinetics (joint moment) - GRF goes through joint (zero)

Question 3

Name the Phase:

Critcal Events Present -

Hip Kinematics -

Hip Muscles activated -

Hip Kinetics (joint moment) -

Answer 3

Midstance

Critcal Events Present - Controlled tibial advancement

Hip Kinematics - Flexion 0

Hip Muscles activated - N/A, glutes turn off as limb is in neutral

Hip Kinetics (joint moment) - GRF is zero (through the joint)

Question 4

Pelvis Muscles activated -

Answer 4

Midstance

Pelvis Kinematics - 0 rotation

Pelvis Muscles activated - Glute Med

Ipsilateral shoulder to reference limb movement-

Answer 5

Midstance

Trunk Kinematics - Erect

Trunk Muscles activated - Extensors & Abdominals

Ipsilateral shoulder to reference limb movement- Rotated Forward

Question 6

Name the Phase:

Critcal Events Present -

Ankle Kinematics -

Ankle Muscles activated -

Ankle Kinetics (joint moment) -

Answer 6

Terminal Stance

Critcal Events Present - Controlled ankle dorsiflexion, Hip extension (trailing limb)

Ankle Kinematics - dorsiflexion 10 (max ankle reaches)

Ankle Muscles activated - GastrocSoleus

Ankle Kinetics (joint moment) -GRF is anterior

Question 7

Name the Phase:

Critcal Events Present -

Knee Kinematics -

Knee Muscles activated -

Knee Kinetics (joint moment) -

Answer 7

Terminal Stance

Critcal Events Present - controlled ankle dorsiflexion, hip extension (trailing limb)

Knee Kinematics - flexion 0-5 degrees, should really be straight as body moves in front of the knee

Knee Muscles activated - Passive structures behind the knee

Knee Kinetics (joint moment) - GRF is anterior

Question 8

Name the Phase:

Critcal Events Present -

Hip Kinematics -

Hip Muscles activated -

Hip Kinetics (joint moment) -

Answer 8

Terminal Stance

Critcal Events Present - controlled ankle dorsiflexion, hip extension (trailing limb)

Hip Kinematics - Extension 20 degrees

Hip Muscles activated - Passive structures in front of hip

Hip Kinetics (joint moment) - GRF is posterior

Name the Phase:

Pelvis Kinematics -

Pelvis Muscles activated -

Answer 9

Terminal Stance

Pelvis Kinematics - 5 degrees backward rotation

Pelvis Muscles activated - Glute Med

Question 10

Name the Phase:
