Study Guide Q's: Assessment and Evaluation Flashcards
Describe temporal changes with gait as we age (2)
- Decreased self-selected gait speed
- Increased stance time and double limb support time
Describe spatial changes with gait as we age
- Decreased step length
- Decreased stride length
- Increased step width (not a universal finding across studies)
Describe kinematic/postural changes with gait as we age
- Decreased excursion of movement at lower extremity joints
- Decreased reliance on ankle kinetics and power
- Less upright posture
What does increased variability of gait as we age mean?
Defined as variability in step or stride time, length, or width
Gait speed of ≥ 1.2 m/s indicates
- Extremely fit
- Can cross street safely
Gait speed of ≥ 1.0 m/s indicates
- Healthy older population with lower risk of hospitalization or adverse health events
- Independent in ADLs
Gait speed of <1.0 (vs. greater than or equal to 1)
- Increased risk for cognitive decline within 5 years
- Increased risk for death and hospitalization within 1 year
Gait speed of < 0.8 m/s indicates
- Increased risk of mortality and mobility/ADL disability at 2 years
- Limited community ambulator
Gait speed of <0.7 m/s
Increased risk of death, hospitalization, institutionalization, and falls
Gait speed of <0.4 m/s
- Functional dependence
- Severe walking disability
Gait speed of <0.2 m/s
- Extremely frail
- Highly dependent
Ways to assess gait speed (instrumented tools)
- GAITrite
- Prokinetics
- Wearables
Ways to assess gait speed (manual tools)
- Stop watch
- Smartphone app
10 MWT significant values (also 2MWT)
- ≥1.2 m/s: cross street
- ≥1.0 m/s healthy aging
- <1.0 m/s inc risk of disability
- <0.8 m/s cut off frailty
- 0.5-0.8 m/s mod frailty
- <0.5 m/s severe frailty
