Definitions of Gait - Class 6 Flashcards
gait cycle
time interval or sequence of motions by which 2 consecutive initial contacts of the same foot
or heel strikes of the same foot
2 major phases of the gait cycle
stance and swing
5 subphases of gait
heel strike
foot flat
midstance
heel off
toe off
stance phase accounts for
60% of the gait cycle
has 5 subphases
heel strike
the initial contact phase
heel strike accounts for
first 10% of the gait cycle
heel strike is a period of
double support
other leg will be in toe off
loading response is also called
foot flat
foot flat
period from heel strike to contralateral toe off
starting to accept weight onto that other limb
mid-stance
period when 1 leg alone is the carrier of the BW
mid stance is a
balancing time
strength –> midstance
leg has to be strong enough to support our body weight
what occurs at midstance
lots of complications
terminal stance is also called
heel off
heel off
the period of midstance to contralateral heel strike
heel off is
taking weight off of the reference limb and putting it onto the contralateral limb
pre-swing is also called
toe off
toe off
period from heel off to toe off
moving towards the swing phase
swing phase accounts for
approx 40% of the gait cycle
has 3 subphases
swing phase is
period when the foot is NWB and moving or forward
when does swing phase occur
from toe off to heel strike
3 subphases of swing
initial swing
mid swing
terminal swing
initial swing is also called
acceleration
acceleration
period when the foot is lifted off the floor
as we accelerate our limb forward
we must shorten it –> rapid hip flexion, knee flexion and DF –> clear leg from ground
when does mid swing occur
when the swing leg is adjacent to the WB leg
balance time
terminal swing is also called
deceleration
deceleration
swing leg is slowing down in preparation for heel strike
deceleration includes
eccentric muscle contractions
