KNES370 FINAL EXAM
QUESTIONS WITH CORRECT
ANSWERS 100% 2024
Developmental Coordination Disorder (DCD) - CORRECT ANSWERS-children
who have difficulty in their movement control & coordination
symptoms: balancing on one leg, prehension (tying shoes, zipping coat),
fundamental motor skills (catching, throwing, skipping)
diagnostic criteria:
- learning an execution of coordinated motor skills below expected level
- motor skill difficulties significantly interfere with activities
- onset early during development
- not better explained by intellectual delay, neuro condition
DCD Subtypes - CORRECT ANSWERS-1. fine motor skills
2. balance
3. visuomotor skills (e.g. ball skills)
typically have difficulties in ~2 areas
DCD comorbidities - CORRECT ANSWERS-can occur independently but can
often have other conditions:
1. ADHD
2. Autism
3. specific language impairment (SLI)
4. anxiety
5. depression
sensory reweighting - CORRECT ANSWERS-ability to adaptively change our
reliance on different sensory modalities; based on how reliably different
senses indicate self-motion
ex: if visual scene starts to move, we reduce reliance on vision
study testing in DCD affects sensory reweighting - CORRECT ANSWERS-- vary
amount of touch-bar motion and visual-scene motion to change; reliability of
somatosenstion & vision as indicators of self motion
- visual gain = amount of postural sway/amount of visual-scene motion
, - measures reliance on vision
- changes in visual gain indicate sensory reweighting
RESULTS
- TD (typically developing) children show sensory reweighting (decrease
visual gain)
- higher reliance on vision when visual scene motion is low, reliance
decreases when motion increases
- children w DCD show less sensory reweighting
validity - CORRECT ANSWERS-a measure that actually measures the concept
that one claims it measures
two types:
1. face validity
2. content validity
face validity - CORRECT ANSWERS-a measure has face validity if it is related
to the concept being measured more than to other concepts
ex: the length of time a child can stand on one foot has FACE validity to
measure balance
content validity - CORRECT ANSWERS-covers full range of the concept's
meaning
ex: for a measure of balance to have content validity it must reflect both
static and dynamic balance
criterion validity - CORRECT ANSWERS-measure has criterion validity if it
matches results from a more direct or already validated measure of the
same concept (the criterion)
- concurrent validity: the criterion is measured at (about) the same time
- predictive validity: criterion is measured in the future
Tinetti Balance test - CORRECT ANSWERS-Predictive validity
- used to assess fall risk in older adults
- has a balance and a gait section and add up scores to predict risk
- 70% sensitivity
- 52% specificity
sensitivity - CORRECT ANSWERS-true positive
- of all the people who have, the proportion correctly identified
