Observational Gait Analysis Flashcards
1 gait cycle equals blank length
stride
gait cycle breakdown
60% stance + 40% swing
heel strike of one foot to heel strike of the opposite
1 step
heel strike of one foot to heel strike of same foot equals one blank
stride
two types of gait analysis
rancho los amigos, phases of gait
RLA definition of initial contact
when heel contacts the ground
loading response rla definition
from heel contact to heel flat
the percentage of time that both feet are on the ground is about
22% of the time
rla where foot is flat until the body is supported over the weight bearing limb
midstance
from midstance to heel off rla phase
terminal stance
heel off until toe off of WB extremity rla
preswing
toe off until max knee flexion rla
initial swing
max knee flexion until tibia is in a vertical position
midswing
vertical tibia position until just before initial contact of ipsi extremity
terminal swing
subtalar joint is between the blank and blank
talus, calcaneus
during initial contact, subtalar joint is blank, ankle / talocrural joint is blank
supinated (locked), neutral
when flexion moment is desired motion and there is a flexion moment due to gravity, the blank is the agonist while blank is the antagonist
gravity, quads
when flexion moment is undesired motion and there is a flexion moment due to gravity, the blank is the agonist while blank is the antagonist
quads, gravity
triceps surae is made up of
soleus, medial/lateral gastrocnemius heads
emg during gait at knee beginning with 5 degrees flexion and going to 0 degrees…. no muscle activity because blank is the check rein
posterior capsule (dense ct)
