Balance, coordination, and function Flashcards

1
Q

What are the parts of postural control and balance?

A
  1. stability (static postural control)
  2. controlled mobility (dynamic postural control; moving in and out of positions)
  3. anticipatory control - know something’s coming and make changes accordingly
  4. automatic control - maintaining balance and control when you don’t know it’s coming

Q

What are motor strategies for balance?

A
  1. righting reactions - orient head in space and body in relation to the head and support surface
  2. equilibrium reactions - protective reactions (ankle, hip, and stepping strategy)

Q

How do we test Anticipatory Control vs Automatic Control?

A
  • Anticipatory Control – pt has eyes open; “I’m going to push in different directions I want you to hold you position”
  • Automatic Control - pt has eyes closed; taking vision out, must rely more on proprioception and vestibular systems; Still tell them what you’re going to be doing; Consider safety, if testing this is appropriate even (fall risk?)

Q

What are the balance grades? (4-0)

A
  • 4 - Normal - Static: maintains steady balance wo/HHS; Dynamic: weight shifts easily, w/in full range, in all directions when maximally challenged
  • 3 – Good - Static: HHS not req’d; min-postural sway present; Dynamic: accepts mod-challenge; can pick object up off floor
  • 2 – Fair - Static: HHS req’d, and occasional min-assist req’d; Dynamic: accepts min-challenge; can turn head
  • 1 – Poor: Static: HHS and mod-to-max-assistance req’d; Dynamic: LOB when challenged or attempts movement
    0 - Absent: Unable to maintain static or dynamic balance

16
Q

inability to judge the distance or range of a movement

A

dysmetria

Cb pathology

17
Q

movement performed in a sequence of component parts rather than as a single, smooth activity; decomposition

A

dyssynergia
(Cb pathology)
- finger to therapist’s finger, finger to nose, alternate heel to toe, toe to examiners finger

18
Q

ataxic pattern, broad BPS; postural instability; high-guard position of UEs

A

Gait disorders

Cb pathology

19
Q

rhythmic, quick, oscillatory, back-and-forth movement of the eyes

A

nystagmus
(Cb pathology)
- red flag when straight vertical; means CNS impairment (vestibular has rotational component

20
Q

inability to halt forceful movements after resistive stimulus removed; pt unable to stop sudden limb motion

A

rebound phenomenon

Cb pathology

21
Q

involuntary oscillatory movement resulting from alternate contractions of opposite muscle groups

A

tremor
- intentional = during voluntary movement; increases as limb reaches target
- postural = movement of body in standing posture or of a limb (?) against gravity
(Cb pathology)

22
Q

rhythmic oscillations of the head; axial involvement of the trunk

A

titubation

Cb pathology

23
Q

inability to initiate movement; associated with fixed posture

A

akinesia

BG pathology

24
Q

slow, involuntary, writhing, twisting, “wormlike” movements; frequently greater involvement in distal UEs

A

Athetosis

BG pathology

25
Q

Decreased amplitude and velocity of voluntary movement

A

Bradykinesia

BG pathology

26
Q

A

choreoathetosis

BG pathology

28
Q

A

hemiballismus

Q

What are some functional assessments?

A
  1. Barthel index
  2. Functional independence measure (FIM) - req’d for medicare inpatient rehab
  3. outcome and assessment information set - req’d for home health initial eval (housekeeping, laundry, phone, locomotion)
  4. SF-36
35
Q

What are some gait assessments

A
  1. timed walking tests
  2. distance tests (3, 6 qw min)
  3. DGI - sensitive in likelihood of falls in elderly and vestibular dysfunction
  4. walkie talkie test - determines attentional demands; pt slows down/ staggers/ loses balance/ has to stop = + fall risk
36
Q

What are the purposes of an environmental/ home assessment?

A
  1. Degree of safety and level of function in physical environment
  2. ID barriers to performance of tasks - railings? Clutter Lighting? Lighting at Night?Carpets?
  3. Make recommendations about accessibility and accommodations
  4. Determine need for adaptive equipment or assistive technology
  5. Assist in preparing pt and family/support network for return home
    - Often performed when significant change in status (SCI, Stroke, Significant remission w/MS)
37
Q

What is the progression of balance testing/activities in standing?

A
  1. Feet shoulder width apart
  2. Turning head
  3. Moving extremities/reaching inside BOS
  4. Weight shifts fwd/bwd and lateral
  5. Feet together
  6. Tandem stance
  7. Feet shoulder width apart eyes closed
  8. Reaching outside BOS
  9. Standing on one leg
  10. Perturbations
  11. Perturbations with eyes closed
    - Same progression on a dynamic surface (foam
38
Q

What is the progression of balance testing/activities in sitting?

A
  1. Feet shoulder width apart on floor
  2. Turning head
  3. Moving extremities/reaching inside BOS
  4. Weight shifts fwd/bwd and lateral
  5. Raise surface - feet off floor
  6. Feet on floor eyes closed
  7. Reaching outside BOS
  8. Perturbations
  9. Perturbations with eyes closed
    - Same progression on a dynamic surface (foam)
