Q

Gait and cognition

A
  • 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

Q

Motoric Cognitive Risk Syndrome (MCRS)

A

slowed gait and subjective cog impairment

  • 2-3x more likely to develop dementia than those w/o MCRS

  • traffic level
25
Q

T/F: Clinical gait training focuses on getting from point A to point B

A

False

MUST include more

26
Q

Assistive Device considerations

A
  1. find best device on stability-mobility continuum
  2. proper adjustment, use, and footwear
  3. energy cost
  4. resistance of use
  5. environmental barriers
27
Q

Assessing Hait

A
  1. Dx and relevent comorbidities
  2. social Hx including PLOF
  3. Body system screening
  4. Observational gait analysis
  5. Instrumental gait analysis
  6. level ground vs stairs
  7. gait speed
  8. outcome measures
28
Q

Specific assessment for gait

A
  • ROM
  • Strength
  • Motor Control
  • Joint P!
  • Coordination
  • Somatosensation
  • Vestibular
  • Proprioception
29
Q

Assessing Gait:

Stair Negotiation

A
  • requires greater ROM and muscle strength
  • ascending vs descending
  • usual pace walking speed and SLS time best
  • safety, handrails, step-to, AD, physical assist
30
Q

Geriatric Gait Interventions

A
  1. flexibility
  2. strength
  3. power
  4. agility
  5. CV training
  6. multimodal training
31
Q

Interventions:

Strength

A

LE strength associated with improved gait speed and function

32
Q

Interventions:

Power

A

rapid bursts needed for motor control

33
Q

Interventions:

CV training

A

aerobic exercise enhances functional endurance

34
Q

Intervention:

Specificity of training

A

what is the goal?

35
Q

Intervention:

training speed

A

increase of as little as 0.1 m/s can reduce disability and mortality

36
Q

Intervention:

progressing task and environment

A
  1. reactive, predictive, and anticipatory control
  2. obstacle courses
  3. dual task
37
Q

Intervention:

obstacle courses and stair training

A
  • altered terrain
  • obstacle avoidance
  • steps
  • ramps
38
Q

Intervention:

Directional training

A
  • backward and lateral stepping
  • turning 90/180/360 degrees
  • backward walking slower than 4 m/s may increase fall risk
39
Q

Intervention:

Dual Task

A
  • reduction in gait speed w/simple vs complex dual task
  • increased gait variability leads to decreased postural stability
    examples: counting backwards, animal naming
