Gait Flashcards
what is heel strike?
instant heel contacts the ground
what is loading response?
From heel contact to foot flat
Phase continues until contralateral limb lifts off ground
what is mid stance ?
From foot flat position until the body above is supported over the weight bearing limb
Begins when contralateral extremity lifts off the grounf
What is terminal stance?
From mid stance through heel off the WB extremity
From mid stance until initial contact of contralateral extremity
what is presswing?
From hell off until toe off of the WB extremity
what is initial swing?
from toe off until maximum knee flexion of ipsilateral extremity (thigh perp to floor)
what is midswing?
From Max knee flexion until tibia is in a vertical position
what is terminal swing?
From vertical tibia position until just before initial contact of the ipsilateral extremity
during initial contact/ heel strike what is the ankle / TC joint doing?
Neutral
Sagittal plane
during initial contact / heel strike what is the subtalar joint doing?
supinated
during initial contact / heel strike what are the toes doing?
15° extension
during loading response / foot flat what is the ankle doing?
PF 15° (= 15° PF IC to LR)
during loading response / foot flat what is the subtalar joint doing?
Begins pronation (GRF lateral to ICR)
during loading response / foot flat what are the toes doing?
Flexing
during mid stance what is the ankle doing?
5-10° DF (= 20-25° DF from LR through MS)
during mid stance what is the subtalar joint doing?
LR through MS completes pronation
Supination begins at MS & is complete by end of mid stance
