Gait Final Exam Flashcards
Total ROM of the ankle during running gait (sagittal plane)
30 degrees of DF - 20 degrees of PF
When does peak DF occur during running and what angle (sagittal plane)
30 degrees at MST
What is peak PF during running and what angle (sagittal)
20-degrees PF right after toe off
Frontal plane: What is angle of the ankle joint in IC during running gait
5-10 degrees of inv (moves toward eversion very quickly
when does peak eversion occur during running and what angle
MST (then starts to invert again as we get ready for push off)
what is the peak eversion degrees during running gait and when does it occur
5-10 degrees of eversion and in mst
which rocker does concentric G-S occur in?
forefoot rocker
which rocker does eccentric PF occur in
ankle rocker
which rocker does eccentric DF occur in
heel rocker
more than 15 degrees is whta type of pelvic tilt
posterior
less than 10 degrees is what type of pelvic tilt
posterior
what type of pelvic tilt at IC during running
posterior (then moves toward anterior)
most common place for a stress fx
tibia
what is associated with stress fractures
high impact loading
what can lead to ITB syndrome
hip add + tibial IR
pronation above _____degrees is considered excessive in gait
12 degrees
do forefoot strikers have more or less knee flexion at FS
more
do forefoot strikers have a higher or lower EV and DF velocity during running?
higher
main causes for flat foot contact in WA (2)
- Incomplete knee ext due to weak quads
2. Excess PF in TSW
main cause for foot slap in WA (1)
- weak tib ant
main causes for excess PF in WA or SLS (2)
- weak quads so the leg extends too much
2. PF contracture
main causes for excess PF in SLA (2)–> this is a fall risk!!!
- Weak tib ant
2. PF contracture
causes of drag during SLA (3) –> fall risk
- weak tib ant
- PF contracture
- Limited hip or knee flexion or excess PF
what nerve is tibialis anterior innervated by and what nerve levles
deep/common peroneal nerve (L4-L5)
causes of excess DF during WA (2)
- excess knee flex
2. excess hip flex
causes of excess DF during SLS (2)
- weak G-S
2. excess hip or knee flexion
causes of excess inversion during any phase (2)
- overactivity of tib post
2. decrease in selective control of tib ant
causes of excess eversion during any phase (2)
- weak tib post
2. hypertonicity of perneals
casues of heel off in WA/SLS (3) –> heel off when it should not be seen
- excess PF
- heel pain
- Excess Knee flex
causes for no heel off (3)–> heel off NOT seen when it should be seen (during tst and psw)
- weak G-S
2. ankle/ met head pain
causes for contralateral vaulting during SLA (1)
- other leg not able to clear so CL vaulting occurs (could be lack of hip flexion or knee flexion or DF occuring)
causes of limited knee flexion during WA? (2)
- weak quads
2. knee pain
causes of limited knee flexion during SLA?
- quad hypertonicity
2. no heel off or hip extension at TST
causes of excess knee flexion at WA/SLS
- knee flexion contracture
- increased DF
- increased hip flex
causes of excess hip flexion at Isw/Msw
- lack of hip flexion or lack of DF so the knee compensates with excess flexion
causes of excess knee flexion during Tsw?
- knee flexion contracture
- hamstring hypertonicity
- weak quads
causes for wobbling? (WA/SLS)
- quad hypertonicity
- pf hypertonicity
- imparied proprioception
causes of knee hyperextensin or extension thrust at WA/SLS
- excess PF
- forefoot contact
- weak quad or quad hypertonciity
causes of limited hip flexion during WA
- limited hip flexion during tsw
2. done to decrease the demand on the hip extensors
causes of limited hip flexion during SLA
- weak hip flexors
- hip pain
- tight capsule that impairs ROM
Excess hip flexion during WA/SLS
- hip flexion contracture
- increased DF
- increased knee flexion
excess hip flexion during SLA
- compensatory for excess PF and/or lack of knee flexion
functional signficance of past retract (hip)
decreases the step length
causes of posterior pelvic tilt during any phase
- tight hamstrings
2. limited lumbar extension
cause of posterior pelvic tilt during SLA
intentional to advance the swing limb
when one limb is in LR the other limb is in what
PSw
max anterior tilt occurs in what phase
terminal stance
max posterior tilt occurs in what 2 phases
ISW and MSW
does anterior or posterior pelvic tilt occur when the limb is on the ground
anterior
does anterior or posterior pelvic tilt occur when the limb is in the air in swing
posterior
causss of anterior pelvic tilt
- weak abdominals
2. hip flexion contracture
ipsilateral pelvic drop during WA/SLS is due to what
weak IL calf muscles
ipsilateal pelvic drop during SLA is due to what
weak gluteus medius on the oppsitie side
cause of backward lean during WA/SLS
- decrease the demand on the hip extensors
cause of backward lean during SLA
- weak hip flexors or poor control of hip flexors
causes of forward lean during SLS
- decrease the demand on the quads
2. use of UE aids
more than 10 degrees is anterior or posterior pelvic tilt???
anterior (this occurs when the leg is on the ground)
less than 10 degrees is anterior or posterior pelvic titl????
posterior (this occurs when the leg is in swing)
