Gait Flashcards
what step length is seen in prosthetic users
- asymmetric
- potentially due to spending less time in stance on involved side
- results in shortening swing time and step length on non-involved side
what happens to gait speed when step length is decreased
decreased
what are some common reasons for decreased gait speed in this population?
- decreased confidence/fear
- lack of gait training
- pre amp gait speed
when you have a loss of plantarflexors due to amputation or weakness what happens:
- shorter contralateral step length
- reduced gait speed
- impaired balance
what phase of gait will be most noticeable with a loss of plantarflexors due to amputation or weakness
midstance
what produces the most force for knee flexion during swing phase
activity at the hip and ankle
no prosthetic mechanism is needed to produce knee flexion given:
- the individual can flex the hip
- ambulate fast enough to produce momentum
goal of transtibial prosthetic gait
gait that is as close to normal as possible
transtibial prosthetic gait
IC/LR:
stride length
controlled knee flexion
transtibial prosthetic gait
MSt:
pylon position
step width
transtibial prosthetic gait
TSt:
smooth progression over the foot
smooth flexion of the limb
transtibial prosthetic gait
PSw:
pelvic, trunk and head position
maintains stability and muscular ability
transtibial prosthetic gait
swing phase:
prosthetic path should be normal
pistoning
- decrease in linkage
- up and down movement while walking
bellclapping
hitting anterior portion of socket
