|
what is the interval of gait
|
from heel strike of one foot to heel strike by the same foot
|
|
|
what are the two main components of the gait cycle
|
stance phase(CKC)
swing phase(OKC) |
|
|
what is the interval for stance phase
|
from heel strike to toe off of the same foot
|
|
|
what is the interval for swing phase
|
from toe off to heel strike
|
|
|
what are the other significant milestones of gait
|
full forefoot loading
heel off or heel lift toe off or propulsion |
|
|
what percent of gait is spent in stance phase
|
62%
|
|
|
what percent of gait is spent in swing phase
|
38%
|
|
|
what two actions occur in the foot during swing phase and in what order
|
1st it pronates then it supinates
|
|
|
what are the functions of pronation during swing phase
|
functionally shortens the limb to help foot clear the ground
minimizes energy used for ground clearance as the non-weight bearing limb passes the weight bearing limb |
|
|
what is the function of supination during swing phase
|
stabilizes the osseous structure of the foot perparing it for heel strike
|
|
|
what are the three periods of stance phase
|
contact period
midstance period propulsive period |
|
|
what are the percentages of the different periods during stance phase
|
contact=27% of stance
midstance=40% of stance propulsive=33% of stance |
|
|
what is full forefoot loading a transition between
|
a transition from contact to midstance
|
|
|
what heel lift or heel off a transition between
|
from midstance to propulsion
|
|
|
what is toe off a transition between
|
from propulsion to swing phase
|
|
|
what is the interval for contact period of stance phase
|
from heel strike of one foot to toe off of the other foot
|
|
|
what is happening at the same time as toe off of the opposite
|
full forefoot loading of the same foot
|
|
|
what is the interval for midstance period
|
toe off of the opposite foot to heel lift on the same foot
|
|
|
what is the interval for propulsive period
|
from heel lift of the same foot to toe off of the same foot
|
|
|
what is the position of the foot at heel strike
|
supinated
|
|
|
what happens to the STJ at the start of weight bearing and during the contact period
|
STJ pronates to absorb shock
|
|
|
What happens to the leg during contact period
|
leg internally rotates
|
|
|
what happens to the STJ from midstance through propulsion
|
it now supinates
|
|
|
what happens to the leg through propulsion
|
it externally rotates
|
|
|
at the start of midstance what is the position of the STJ
|
pronated
|
|
|
what does supinating the STJ do to the foot
|
changes it from mobile adaptor to rigid lever
|
|
|
what happens to the STJ just prior to toe off what is the function of this
|
it pronates to shift weight from lateral to meidal and load metatarsal heads 2, 3 and hallux
|
|
|
what are the effects if the STJ is pronated during propulsion
|
foot and leg muscles must work harder to carry out propulsion
|
|
|
when is the STJ neutral
|
when it is neither pronated or supinated
|
|
|
what is the motion of contact
|
pronation
|
|
|
what is the action of midstance and propulsion
|
supination
|
|
|
what is position of contact and midstance
|
pronated
|
|
|
what is the position of propulsion
|
supinated
|
