Impairments that interfere with walking (Ebook 3) Flashcards
Gait deviations that occur in all phases of motion demonstrate issues with what?
flexibility of the joint
gait deviations observed in almost all phases with excessive stiffness, jerk or wobble
check hypertonicity using modified ashworth
if the individual aligns the GRF so that they can rely on passive structures during stance phases what should be checked?
hypotonicity - utilizing qualitative descriptions of muscle tone
ALSO strength should be assessed
if individual has difficulty with anti-gravity motion during SLA
strength of muscles activated during SLA should be assessed
Impaired muscle activation should be checked if there is
insufficient amplitude of muscle activity; if they have difficulty moving through their entire ROM or moves excessively during the task
impaired muscle activation is confirmed using…
EMG or observation
if the individual has difficulty getting sufficient amplitude of motion during SLA or stabilizing joint during, but their strength is still intact
assess timing of muscle activation
if they have a stiff or arrhythmic pattern their _____________ should be assessed
sequencing of muscle activity; using EMG or observation
proprioception should be examined if…. using kinesthetic joint testing
- alligns the GRF to rely on passive structures during stance phases (like ankle plantarflexion and knee hyperextension) to ensure stability
- wide BOS is seen
- excessive variability of walk
vestibular function should be further examined if
- the individual has limited head motion
- wide BOS
- limited time in SLS
- poor reactive balance
- difficulty with low light
- difficulty with surface with grade and compliant surfaces
Pain should be assessed using VAS if…
- less time in SLS (especially TSt)
- limits motion during phases of high joint moment
- grimaces during walking
shortened gastroc/soleus (-15 degrees ankle dorsiflexion)
- compensates with knee hyperextension during WA and MSt to keep foot flat
- allows tibia to be posterior to vertical to maintain plantarflexion
- foot flat observed at LR, MSt and TSt
- early heel off in MSt
- SLA excessive plantarflexion + compensatory strategies to clear swing limb
compensatory strategies for a shortened gastroc
- excessive hip and knee flexion
- contralateral vault
- hip hike
- hip abduction aka circumduction
Shortened gastroc/ soleus (-30 degrees of ankle dorsiflexion)
- heel off through all stance phases
- SLA - excessive plantarflexion + compensatory strategy to clear SL
- forefoot contact will be observed
- excessive plantarflexion through all phases of gait
shortened hamstring + popliteal angle of >45 degrees
- lacks extension
- walk with excessive hip and knee flexion during stance phases (except PSw)
- TSw puts hamstrings in max stretch–> difficult for this person
shortened iliopsoas with Thomas test >10 degrees
- lacks hip extension
- walks with excessive hip flexion, knee flexion, and dorsiflexion during all stance phases
- anterior pelvic tilit
- TSt puts iliopsoas in stretch = problematic
hypertonicity of gastroc-soleus
- excessive plantarflexion through gait pattern
- compensatory mechanism observed to clear swing limb
- knee wobble may be observed at WA
hypertonicity of hamstrings
- excessive knee flexion during stance phases and at TSw
- excessive hip flexion and ankle dorsiflexion during stance phases
hypertonicity of quads
- difficulty with SLA (PSw and ISw)
- limited knee flexion at LR, PSw, and ISw
- limited hip flexion at LR, PSw, and ISw
- knee wobble at LR and PSw
hypertonicity of iliopsoas
- difficulty with TSt
- excessive hip flexion at TSt
- anterior pelvic tilt
- limb is unloaded during SLA (jerky motion may be observed at the thigh)
weak TA
- greatest difficulty with SLA
- forefoot contact or foot slap
- excessive plantarflexion during SLA + compensatory strategy (hip hike, contralateral vault, knee flexion, hip circumduction)
weak gastroc/soleus
- difficulty stabilizing the limb during SLS
- excessive dorsiflexion + knee flexion and hip flexiion at MSt and TSt
- PSw difficulty pushing knee forward using plantarflexion - excessive dorsi and limited knee and hip flexion
