This condition is a result from ischemic or hemorrhagic lesions in the brain.
Difference between hemiplegia and hemiparesis
- plegia is paralysis
- paresis is weakness
CVA occurs more in male or female
whats the etiology of a cerebral thrombosis
- formed by arthrosclerosis or plaque formation and progressive narrowing of arteries
- leads to a blood clot (thrombus)
whats the etiology of a cerebral emboli
traveling particles of matter which maybe become lodged in a cerebral artery causing occlusion and infarction
which is more common cause of CVA thrombosis or embolus
HTN, DM, PVD, and heart disease are some primary risk factors for what
define ischemic prenumbra
area around the core of damage but somewhat functional cells
about how long does it take for cerebral edema secondary to a CVA to reach its max? how long till subside?
t/f with a TIA there is residual damage
which cerebral artery is most common CVA
which CVA has sx of LE hemiparesis, sensory loss, grasp reflex, unilateral neglect, aphasia, apraxia, and agraphia? Which lobes/structures are affected?
- frontal and parietal lobes
- internal capsule, corpus collosum
which CVA has sx of hemiparesis or plegia of face and arm more than leg, homonymous hemianopsia, motor hemiplegia without sensory or visual, aphasia, anosognosia, apraxia, spatial disorganization
what structures are affected with MCA
- lateral aspect of cerebral hemisphere
- temporal, frontal and parietal lobes
- posterior internal capsule
- caudate nucleus
which cva presents with contralateral sensory loss, homonymous hemianopia, thalamic pain syndrome, visual agnosia, cortical blindness
ataxia, decreased DTRs on same side, asthenia, intentional tremors, and nystagmus are all signs of this type of disorder
- (asthenia is muscles fatigue easily)
which hemisphere is affected if you see apraxia, longer to learn a task, sequencing movements, aphasia, difficulty with math and analyzing details
which hemisphere is affected if you see inability to sustain activity, unilateral neglect, poor visuspatial and body image, and hard time grasping the "larger picture"
referring to TBI what is coup and contrecoup
- coup is first impact
- contrecoup is the following hit
your patient has decreased responsiveness, impaired consciousness, severe HA, vomiting, irritability, papilledema (optic disc swelling), and increased BP with decreased HR what is happening?
glasgow scale measures what?
amount of consciousness
what level of los ranchos amigos cognitive scale can a person be mod I
whats the posture difference between decerebrate and decorticate
- corticate the UE flex
- cerebrate the UE ext
be aware of too much stimulation with this condition
Name the 3 systems of balance and what each is
- somatosensory- patient's tactile input
- vestibular- understand position in space
what is the 4 motor types of strategies in regards to balance
- suspensory (lowering COG toward BOS)
This approach involves key points and normal movement pattern also a focus on proximal stability before distal mobility
- neurodevelopment technique
- by Bobath
This approach focuses on inhibition or facilitation techniques. Also practices controlled mobility, skill, stability, and mobility
This approach focuses on utilizing the synergy patterns and primitive voluntary reflexes
This Brunnstrom stage (1-7) spasticity is at its peak
This approach involves strengthening muscles in mass movement patterns in which they were designed to function
- Developed by Kabat, Knott, and Voss
describe the hierarchic theory
- control from top down
- cortex is highest with brain stem than SC
Feed-forward (open loop) is adjustments made during or after the activity?
after performing the activity
whats the affect of achetylcholine on muscles? dopamine?
- Ach- tells muscles to start, excitatory
- dopa- generally inhibitory
this motor neuron is the final common pathway that directly stimulates muscle contraction
alpha motor neuron
alpha motor neuron damage and below is what type of lesion?
