Flashcards in Gait Deck (22):
Name the phases of gait.
initial swing/mid swing/terminal swing
Double limb support occurs during what phases?
DL support occurs: (sides are for example)
- during R heel strike until R foot flat
- after R foot flat contact through R toe off
- then again during R heel strike to R foot flat
What muscles are active during heel strike?
knee extensors to control knee flexion with shock of hitting ground
DFs to control quick lowering of foot
What muscle group is active during foot flat to midstance? Why?
PFs are active to eccentrically control anterior translation of tibia
T/F: Midstance is a period of single-limb support.
true: all weight is supported by stance limb is the criteria of midstance
What muscles are active in midstance?
hip abductors to stabilize
When does peak activity of plantar flexors occur?
after flat foot contact during push off
When does the first period of DL support occur?
after initial contact through loading response
When does the second period of DL support occur?
preswing (right after toe off)
What muscle group causes the forward acceleration of the limb during early swing?
T/F: Hamstrings activate in late swing.
true to decelerate the limb to prepare for IC
T/F: An increased cadence would also have a increased DL support time.
false, sorter step length actually decreases the duration of period of double support
A patient with weak glutes will demonstrate what common gait deviations? What other issues might they have difficulties with that you'll want to assess?
backwards trunk lean
- difficulty going up stairs or ramps
A patient with an antalgic gait due to pain on the R will demonstrate a decreased stance time on what leg? What about step length?
decreased stance time on R
decreased step length on L
A patient with weak knee extensors due to stroke may have difficulty with walking, as well as what other functional activities?
walking down stairs
walking down a ramp
- may see forward trunk bending to compensate
A patient with calcaneus gait will demonstrate what gait deviations?
excessive forward translation of the tibia, aka increased DF with stance and loading leading to crouched gait likely
- due to weak PFs
If a patient demonstrates insufficient forward pelvic rotation, what muscles might be affected?
looking for stiff pelvis, pelvic retraction
- weak abdominal muscles or hip flexor muscles
* see this in stroke
A patient with circumduction for swing phase is likely deficient in what muscles?
Why might a patient be hip hiking?
weak hip/knee flexors on that side
spastic extensors on that side
Why might a patient exhibit a steppage gait?
they can't DF so they need to flex more in other areas to clear the foot
- think stroke, think diabetic neuropathy of deep peroneal nerve
What might abnormal synergistic movement in a patient with stroke look like when they attempt to execute swing phase?
excessive hip/knee flexion with hip abduction
