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
cognition includes what 3 things
attention
motivation
emotion
declarative memory comes from
explicit- hipppo
procedural learning happens due to what brain part
cerebellum
3 requisites of locomotion
stability
progression
adaptability
___controls reach, while ___ controls grasp
prox-reach
distal-grasp
voluntary control is due to
frontal lobe
coordinator of mvmt
cerebellum
Fitts law
accuracy and speed, large vs wide target) (bigger target the faster you can complete the task-not as fine and skilled) (start with bigger target first)
voluntary control happens due to
frontal lobe
sensations needed for posture and fine motor control
all (sight, touch, proprioception, vestibular)
ATNR is beginning of
eye hand coordination
3 things needed for reflex theory
receptor
pathway
effector
motor control and motor memory dt
cerebellum
language hearing and memory
temporal lobe
executive brain fnct
frontal lobe
sight dt
occipital lobe
sensations dt
pariatal lobe
grasp reflex integration occurs
6mos
intrinsic vs extrinsic feedback
intrinsic- within
extrinsic- outside body
5 main parts to gait measurment
step length step width stride length velocity step rate
what is step length
1 foot strike to anotehr
what is stride legth
q 2 steps
what is step witdth
heel distances
reactive and proactive strategies
reactive - reflexes, (px, temp, tactile, sensory stimulation)
Proactive -come later - jumping over obstacles
part of brain responsible for gait speed
brainstem
part of brain controls start/stop of motion
basal ganglia
we lose type ___ fibers with age
II -fast twitch
factors to the task oriented approach to PT
task
individual
env
all on functional mvmt
Motor control includes ____ controls
postural
Postural control depends on individual char, what are they
BOS
COM
LOS
Sensory and Motor strategies
stability, you go against ___ forces
vertical
progression, you go against ___ forces
horizontal
Main muscle group in gait cycle
hips
motor milestones
2 months for head control and prone on elbows 6 sit 8 crawl 10 pull up 12 walk
what sense is needed for eye/hand coordination
vision
We use ____control during reaching tasks
posture
mental practice happens in what part of brain
frontal cortex
Hip abductors are activated to ____ control the wt shift of the pelvis
eccentrically
stride length
same foot to same foot
children use feed ___
back (reactionary response)
reactive adaptations rely on
