Deck 8: Overview of Balance Impairments: Functional Implications

Question 1

Visually dependent patients are at high risk to lose their balance during which task?

A) Getting up to use the bathroom at night
B) Looking for kitchen utensils in a cluttered drawer
C) Walking on high-pile carpet
D) Standing on an escalator

Answer 1

A
Patients with somatosensory dysfunctions usually become visually dependent.Poor lighting becomes challenging.

Question 2

When the base of support is expanded in the direction of center of mass movement,what type of postural control strategy is used?

A) Stepping strategy
B) Hip strategy
C) Ankle strategy
D) None of the above

Answer 2

A
This strategy expands the base of support to compensate for ineffective ankle and hip strategies.

Question 3

The postural control strategy that is most effective at maintaining stability when the support surface is short in relation to foot length is:

A) ankle strategy.
B) hip strategy.
C) stepping strategy.
D) equilibrium reaction.

Answer 3

B
Hip strategies are most effective when used with a support surface that is short in relation to foot length,the support surface is compliant,or ankle strategies are (or are perceived to be)ineffective.

Question 4

Standing in line at the bank without support requires efficient use of which type of postural control strategy?

A) Lateral weight shift
B) Ankle strategy
C) Hip strategy
D) Stepping strategy

Question 5

Which central nervous system structure is used to integrate postural control information?

A) Basal ganglia
B) Pons
C) Medulla
D) Cerebral cortex

Question 6

Symptoms of cerebellar involvement include:

A) unsteady gait.
B) falls.
C) nystagmus.
D) all of the above.

Question 7

Surface dependent patients are most likely to lose their balance when performing which task?

A) Carrying coffee from a linoleum floor kitchen to a carpeted den
B) Cooking in low lighting
C) Riding on an escalator
D) Walking in a crowded mall

Question 8

A subjective interview that is used to collect information related to balance dysfunction should include:

A) premorbid health.
B) prior functional status.
C) patient's perspective on current function.
D) all of the above.
