lecture 9 Flashcards
what is gait analysis
the analysis of body segments through space and time during locomotion.
one gait cycle
ground contact to the next ground contact of same foot
swing phase
toe-off to ground contact
stance phase
ground contact to toe off
double stance
in walking replaced by flight phase in running.
ground strike
initial ground contact usually with heel
foot flat
heel down, food eversion/pronation
mid-stance
support foot under pelvis, end of loading response, propulsion begins
heel off
knee flexes usually with toe extension
toe off
foot leaves ground
early swing
hip and knee are flexing
mid swing
foot swings under pelvis, max knee flexion and hip still flexing.
late swing
knee extending, hip stops flexing and laterally rotates.
step length
distance between consecutive ground strikes
stride length
distance between consecutive ground strikes of same leg
foot angle
orientation of foot relative to line of progression
base width
ML between ground strikes from heel of each foot.
what can increase with motor impaurment
base width
