STAY POSITIVE Flashcards
Damage at optic chiasm leads to
Tunnel vision
Loss of lateral fields
Homonomous Hemianopsia
Loss of optic tract
Damage to L optic tract or L visual cortex =
Lose R visual field``
Perturbation causing displacement forward - what first with ankle strat
Gastroc, hams, then paraspinals
Perturbation causing displacement backward - what first
DF, hip flexors, abdominals
Hip - fall forwards what happens
Quads and abs
Hip - fall backwards what happens
Hams and paraspinals
Anterior cerebral artery - leads to
contralateral weak and sens dec in LEs
Cant walk to phoen but could call
Post cerebral artery
Contralateral homonymous hemianopsia
Memory dec
Too dizzy to walk to phone and can’t see dial
Middle cerebral artery
UE and face more than LE
B and W
Can walk to phone but can’t talk
R vs. L hemisphere CVA
R = naughty and neglect L = language, poor motor planning
Intracranial pressure norm
Less than 10 mm Hg
Mild = 10-15
Mod = 15-20
Severe = 20 or higher
CPP norm
80-90 mm Hg
Always needs to be maintained above 70 mm Hg
When less than that, there will be ischemia to the brain
Calculation for CPP
MAP - ICP
MAP calculation
DBP + 1/3 (sys - dias)
Stupor
Briefly aroused with vig stim
Obtunded
Sleeps a lot and slow to respond
Coma
No spontaneous EO or response to stim
Vegetative state
Intact EO, sleep/wake cycles, but no speech or following commands
Central cord syndrome
More impairment to UE than LE
Loss pain/temp at level of lesion but intact above and below lesion
Anterior cord syndrome
Impaired corticospinal B - weakness and reflex change
Impaired spinothalamic B - pain and temp lost
