assessing gait in older adults Flashcards
gait cycle:
phases of weight acceptance
initial contact
loading response
gait cycle:
SL support phases
midstance
terminal stance
gait cycle:
limb advancement phases
- preswing
- initial swing
- midswing
- terminal swing
Common gait changes with age:
temporal
- decreased step and stride length
- increased stance and DL support time
Common gait changes with age:
spatial
- decreased step and stride length
- increased step width
Common gait changes with age:
kinematic/postural
- decreased excursion of movement at LE joints
- decreased reliance on ankle kinetics and power
- less upright posture
T/F: abnormal gait associated w/progressive risk of institutionalization and death
True
Slow gait speeds:
- defining feature of frailty
- fall pts slower than age match peers
- worse performance across all cog domains
effect of complex dual task on gait in MCI and AD groups compared to healthy
- significant decrease in gait velocity
- increased stride time
- increased stride variability
stride length in AD group compared to healthy controls
decreased mean value and greater CoV
gait variability:
step length and # of steps
reduced mean value for all CDRs compared to CHI at UP, FP, SP, and dual-task conditions
Gait and cognition
- decreased gait and cognition=high risk for dementia
- cognitive domains have critical impact on gait
- MCRS
- strong need to integrate cog demands w/gait and mobility training
Motoric Cognitive Risk Syndrome (MCRS)
slowed gait and subjective cog impairment
- 2-3x more likely to develop dementia than those w/o MCRS
Predictive value of gait speed:
> 1.2 m/s
extremely fit
can cross street safely
Predictive value of gait speed:
> 1 m/s
Healthy older population w/ lower risk of hospitalization or adverse health events
independent in ADLs
