B) Hip strategy
C) Stepping strategy
D) Suspensory strategy

Question 11

A) Proprioception.
B) Somatosensation.
C) Vestibular function.
D) Vision.

Question 12

The center of gravity (COG)in most adult humans is located slightly:

B) Posterior to the S2 vertebra.
C) Anterior to the L2 vertebra.
D) Anterior to the S2 vertebra.

Question 13

A) Center of mass
B) Limits of stability
C) Limits of pressure
D) Center of gravity

Question 14

During an examination of a patient who has a history of episodic falls,you observe the patient performing functional tasks to determine how she loses her balance.You note that the patient becomes unsteady whenever she picks up objects from the floor or reaches for objects in a kitchen cupboard.These findings most likely indicate a control deficit in:

A) Anticipatory balance.
B) Reactive balance.
C) Static balance.
D) Sensory organization.

Question 15

B) Marching in place on a firm surface with the eyes open.
C) Walking with a narrowed base of support on foam with eyes open.
D) Walking with a narrowed base of support on a firm surface with eyes closed.

Question 16

To maintain balance in condition 3 (standing on a firm surface wearing a dome)of the Clinical Test of Sensory Integration on Balance,a person must rely solely on:

A) Somatosensory and vestibular information.
B) Vestibular information.
C) Visual and somatosensory information.
D) Visual and vestibular information.

Question 17

The typical pattern of muscle activation associated with an ankle strategy to correct forward body sway is:
