Match the body parts with their positions during Stage 1: Initial Contact:
Hip = Flexed Knee = Extended Ankle = Neutral Foot = Supinated
Match the body parts with their movements during Stage 2: Loading Response:
Trunk = Lateral shift towards the stance leg Hips = Beginning to extend Knee = Flexing Ankle = Plantar flexing
Match the stages of gait cycle with their descriptions:
Stage 4: Mid Stance = Weight has shifted forwards to the middle of the foot. Stage 5: Terminal Stance = Period from ipsilateral heel off to contralateral foot contact. Stage 6: Initial Swing = Period from toe off through to feet adjacent. Stage 7: Terminal Swing = Period from feet adjacent through to initial foot contact.

Study Notes
Gait Cycle Stages
Stage 1: Initial Contact
- Trunk is behind the leading foot, crossing the midline towards the stance leg, with the right pelvis forward
- Hip is flexed, knee is extended and starting to flex
- Ankle is neutral, and the foot is supinated
- Contact with the ground results in a vertical force vector through the heel and ankle
Stage 2: Loading Response
- Body has travelled over the supporting leg, with the force vector passing through the heel, knee, and in front of the pelvis
- Foot starts to pronate, and tibial internal rotation occurs
- Trunk is in its lowest vertical position, moving laterally towards the stance leg
- Hips begin to extend, knee flexes, ankle plantarflexes, and foot pronates
Stage 3: Foot Flat (Contralateral Toe Off)
- Contralateral limb is at toe off, with the stance limb having the pelvis more over it
- Foot is flat on the ground, with the ankle dorsiflexing as the tibia moves over the foot
- Force vector passes behind the knee and just in front of the pelvis
Stage 4: Mid Stance
- Weight shifts forward to the middle of the foot
- Force vector passes through the middle of the foot, knee, and stance leg
- Tibia moves into external rotation, and knee reaches peak flexion
- Trunk reaches its highest point, with peak lateral motion of the trunk
Stage 5: Terminal Stance
- Second double support occurs, with the period from ipsilateral heel off to contralateral foot contact
- Body shifts body weight to the other limb
- Trunk moves to the opposite side, hip reaches its most extended position
- Knee moves back into flexion, ankle plantarflexes, and foot reaches maximal supination
Stage 6: Initial Swing
- Period from toe off to feet adjacent
- Force vector passes through the last point of the toe and behind the knee and hip
- Trunk moves through neutral towards the new supporting foot, gaining height
- Hip flexes, knee flexes, ankle moves from plantarflexion to neutral, and foot is slightly supinated
Stage 7: Terminal Swing (Late Swing)
- Period from feet adjacent to initial foot contact, with toe clearance occurring
- Trunk moves from maximal displacement on one side back towards the midline, losing height
- Hip flexes, knee extends rapidly, ankle position is not as important, and foot remains in supination
