Questions and Answers

Which brain structures, when damaged, impair processing of incoming sensory information and disrupt anticipatory and reactive postural adjustments?

  • Basal ganglia
  • Cerebellum
  • Supplementary motor area
  • All of the above (correct)

  • No change in response amplitudes
  • Larger response amplitudes (correct)
  • Smaller response amplitudes
  • Normal response amplitudes
  • Which factor increases a person's chance of exceeding his or her limits of stability?

  • Declines due to aging in all sensory systems
  • Muscle strength at one joint altering posture and balance movements throughout the entire limb
  • Postural malalignment shifting the center of mass (COM) closer to the base of support (BOS) (correct)
