Motor Contraints Flashcards
Ataxia is usually dt an issue with the
cerebellum
ataxia is an issue controlling
DOF
what should direct our tx
the motor control impairments themselves (not their dx)
tonic issues (hyper or hypo) are usually what kind of injury
cerebral cortex
weakness or sensory impairments are usually due to what kind of injur
cerebral cortex
parkinsons is a ___kinesia disorder
hypo
huntingtons is a ___ kinesia disorder
hyper
parkinsons and huntingtons are issues with what part of brain
BG
MS is usually an issue with what part of brain
cerebellum
Hughling Jacksons classifications of disorders
pos or neg
Pos - too much response (like increased DTR)
Neg - too little response (like hemiplegia)
primary vs secondary impairment
primary is direct impact from the insult or injury
secondary is a result of the insult (usually effects other sxs)
Motor impairments (e.g., spasticity, weakness)
Speech/language
Cognitive
Perceptual
Behavioral
Visual
(are these primary or secondary impairment)
primary
hemiplegia would be an ex of damage to the
cortex
movement disorders are usually dt damage to the
BG
loss of selective mvmt is damage to the
cortex itself
what is selective mvmt
fractionation - meaning you can fluidly reach to pick up a pen and your motions can be individualized and precice
loss of fractionation of mvmt or loss of selective mvmt would result in
synergystic mvmt (everything moves together always)
pyramid sx is the ___ sx
voluntary
extra pyramid sx is the sx of ___ and involves what structure
coordination
BG
6 components of the motor control framework
Initial cond Prep Initiation Execution Terminate Outcome
the motor planning part of the framework
preparation
amplitude, direction, speed are all parts of what component of the framework
execution
the ability to generate tension is __
strength (depends on number and type of fibers recruited)
strength vs tone
strength is active resistance
tone is passive resistance
absence of tone (2 terms for)
hypotonia
flaccid
highest rating of hypertonicity is
rigidity
flaccidity almost always occurs when
immediately after a stroke (often it returns to normal though)
2 examples of somatosensory abnormality
issues with
disc touch
proprioception
2 ex of visual/perception abnormality
neglect
homogenous hemanoinopsia
most common vessel with stroke is
MCA
what is INR
ability to clot
the lower it is the increased chance of clot
spacticity is related to a ____ issue
cortical
spaciticity is or isn’t velocity dep
spacticity is velocity dependent
hyperactive DTR is an ex of
spacticity
clasp knife is an ex of
spacticity
associated movement is a sx of
spacticity
velocity dependent increase in tone or reflex is
spacticity
do synergistic mvmts adapt
NO - they are not variable
unwanted stereotypical mvmt
flexor synergist pattern for UE
scap elevation abd/ER elbow flexion sup finger flexion
ext is opp of all
flexor synergistic pattern for LE
hip flex abd/ER knee flexion DF and inversion ext toes
sustained (stuck) twisted contraction
dystonia (lady walking down hallway)
proximal limbs violently moving uncontrollably
ballismus
6 stages of recovery (brunnstrom)
flaccid paralysis minimal synergy voluntary synergy some mvmt out of synergy no synergy normal FMVONN
errors in range and direction of movement (woman who cant put cap on pen)
dysmetria
dysmetria is a prob with __
coordination
can’t do rythmic rapid alternating movements
dysdiadochokinesia
when pts limit their DOF bc they cannot control multiple joints moving at one time (only move one at a time)
decomposition
ex: getting up from a chair and they bend their knees first, then bend their trunk (not fluid or together)
rigidity and bradykinesia are associated with what patholgy
parkinsons
bradykinesia is usually dt an issue in the
BG
intention tremor vs resting tremor
intention occurs during movement
resting occurs during rest only (like in PD)
2 types of rigidity
lead pipe
cog wheel
spacticity occurs on ___ side(s) of a joint
1 side
rigidity occurs on ___ side(s) of a joint
rigidity is both sides
rigidity is velocity
independent
slow, twisting, involuntary writhing that is often seen in CP (in the UE)
athelosis
Hypometria and hypermetria are problems with _____
innappropriate force generation (scaling)
hyper and hypmetria are active so abnormal muscle tone isn’t a factor with hyper/hypometria
muscle tone is the _____ (define)
PASSIVE resistance to stretch
flacididy is a ____ phenomenon
passive
dysmetria is a prob with the
cerebellum
If I had Left homonomous hemienopsia I could only see on the ____ sides of vision
right
List the spectrum of tone
flaciddity–>hypotonia–>normal–>spastic–>rigid
which step in the progression of movement is hardest for pts with PD (initiation, preparation, execution, termination)
execution
with PD they have the most difficulty with what types of motor learning strategies
Procedural learning
complex tasks
Random practice
Dual tasking
is hypo/hypermetria any issue with tone
no
Hypometria and hypermetria are problems with innapropriate force generation and a problem with scaling (muscle tone is the amt of resistance at PASSIVE stretch – hyper and hypmetria are ACTIVE so abnormal muscle tone isn’t a factor with hyper/hypometria)
Scaling = amt of mvmt or force
rigidity occurs on ___ side(s) of the joint and is velocity ____
R. I. 2
Rigidity, independent, 2 sides
