Final Spring 2015 Flashcards
medial lateral perterbations do what to hips
enact the hips, flexors unload
extensors load
2 gait adaptations
spin turn
step turn
without vision, pts have to really rely on
proprioception
stride length ___ with age
decreases
fnct of brain stem
primal- breathing, digestion
pariatal lobe
reach, grasping, reaction to env
temporal lobe
language, hearing, memory
power vs precision grip
power- like a baby or holding a hammer
precision - a needle or pen
thalmus
sorts data
feed forward
your reaction is due to a memory implant, it’s anticipatory
catching a ball, your rxn happens
prox to distal
reaction time ___ with more practice
decreases as you learn
grasping is a ___ task
distal
explain ICF model
top tier- med condition
next 3 teirs - body impairment, activity limitation, participatio restriction
lower tiers - env, personal factors
Massed vs distributed
dist is best
Massed - for endurace pts
distributed- when they need more breaks
constant vs variable
constant - same always
variable - mix it up
ex: walking, always in a straight line on concrete vs zig zagging an doing steps
random vs blocked (order)
random is best for long term motor learning
blocked is good for beginner or cog issue
guidance vs discovery
guidence is less effective bc they just do what they are told
Fitts and Posners stages of motor dev
1- Cognition
2- Association
3 -Autonomy
Explain cognition stage of fitts and posner
experimentation, not sure what works best at this point, they are trying to find preffered strategies
Explain associative stage of fitts and posner
they are defining and mastering their preffered strategy
Explain autonomous stage of fitts and posner
its automatic, can now worry about env, and other factors
What is sx model theory
idea that movement is synergistic. there are 3 levels
novice - hardly any dof used
advanced
expert -release/use of all dof
4 main goals of Motor Learning
- generalizability
- retention-repeatable
- quality of performance
- resistance to change
4 stages of motor control
initial mobility
stablity
controlled mobility
skill
standing independently at what age
12 mos
Heirarchy dev with babies (what comes first and what after that)
attitudinal/postural reflexes
righting reactions
balace
posture mastery
Explain ATNR
where the head goes, the UE will follow
STNR
where head goes, arms follow and legs do opp
Tonic Labyrinthian
when head flexes trunk flexes
when head extends trunk extends
attitudinal/postural reflexes effect
tone of ENTIRE body
What sensory sx is most prominent in babies
visual
mental practice happens dt what part of brain
pre frontal
