Geriatric syndrome - ANS a consequence of conditions (involving multiple organ systems
and often lacking firm diagnosis or clarification of underlying causes) common to older adults
and without a specific diagnosis or pathology
To what do we attribute geriatric syndromes? - ANS When diseases interact with the
common and inevitable effects of normal aging
List the shared risk factors that may lead to Geriatric Syndromes - ANS -slow chair stand
time
-decrease UE strength
-decreased vision/hearing
-high anxiety/depression
Changes of the sensory system due to aging - ANS -visual, somatosensory, proprioceptive,
auditory, vestibular.
-Due to changes in end organs (eyes, ears, skin, muscle, tendon) and loss of receptors, sensory
neurons, axons, myelin.
Changes of the CNS due to aging - ANS -Slowed reaction times
-diminished executive functions
-decreased motor control
-due to loss of brain cells, axons, and myelin; decrease in neurotransmitter production
, Changes of the motor system due to aging - ANS -decreased strength, ROM, ability to
absorb shock; increased stiffness.
-Due to loss of motor neurons, axons, myelin, muscle mass, water, elastic fibers; decreased
nerve conduction velocity, number of motor fibers; increase collagen crosslinks
Biomechanical gait changes with aging - ANS Increased:
-stance time
-double stance time
-variability
Decreased:
-gait speed
-step length
-stride length
-excursion of movement
May be the best predictor of functional decline and disability - ANS Gait speed
The 6th vital sign - ANS Gait speed
Diminished gait speed is considered a marker of __________. - ANS poor health
Gait speed is predictive of __________ - ANS -daily ambulatory activity
-mortality
Survival increases across a full range of gait speeds with increments of _____m/s. - ANS
0.1
Relative to predictive capabilities of gait speed, what is the cut point for extremely fit older adults
who can cross the street safely? - ANS >1.3 m/s
Relative to predictive capabilities of gait speed, what is the cut point for limited community
ambulation? - ANS <0.8 m/s
Relative to predictive capabilities of gait speed, what is the cut point for health older adults with
lower risks of hospitalization or adverse health events? - ANS >1.0 m/s
At walking speed < 0.6 m/s, older adults are: - ANS -likely dependent with ADLs and IADLs
-more likely to be hospitalized
At walking speed >1.0 m/s, older adults are: - ANS -independent w/ ADLs
-less likely to be hospitalized
-less likely to have an adverse event
