  12. fibrillation on EMG
    • spontaneous indep contraction of individual muscle fibers
    • present for 1-3 wks after denervation
  13. fasciculations on EMG
    • sponatneous contractions of all or most fibers in a MU
    • can be observed or palpated
    • presnt w LMN disorders and denervation, but not with complete LMN lesions
  14. 3 conditions that'll have decreased conduction velocities
    • GBS
    • chronic demyelinating polyneuropathy
    • Charcot-Marie-Tooth disease

    also seen with focal compression of peripheral nerves
  15. encephalitis
    • severe infection and inflam of the brain
    • 2/2 arboviruses, sequela of influenza (Reye's syndrome, eastern equine encephalitis, measles) sinuvitis, otitis, prion-caused disease (kuru, "mad cow" disease)
  16. pyogenic
    producing pus
  17. brain abscess
    infections process w collection of pyogenic material in brain parenchyma (functional tissue of the brain -- neurons and glial cells)
  18. irreversible anoxic damage to brain begins after __ min
    4-6
  19. occlusion to anterior carotid artery -->
    minimal deficits due to collateral circulation (circle of Willis)
  20. remediation-faclitation approach for CVA
    promote awarenes, active mvmnt, use of hemiplegic side
  21. 3 guidlines for working w pt w L hemisphere lesion
    • develop an appropriate communication base (words, gestures, pantomine... assess the level of understanding and use it)
    • give frequent feedback and support
    • don't underestimate ability to learn
  22. 5 guidlines for working w pt w R hemisphere lesion
    • use verbal cues, (not demos or gestures bc these pts may have visuospatial deficits)
    • give frequent feedback, with a focus on slowing and controlling the mvmnt
    • focus on safety (pt may be impulsive
    • avoid env clutter
    • don't overestimate ability to learn
  23. confusional state
    • mainly a disturbance of attention mechanisms
    • all cognitive operations are affected
    • can't form new memories
    • may demonstrate hypo or hyperarousal

    • emotions, behavior (orbitofrontal)
    • olfaction (orbital gyri)
  26. Brown-Sequard presentation
    • ipsilat loss of tactile discrim, pressure, vibration, proprioception (dorsal columns)
    • iplilat loss of motor function w  spastic paralysis (corticospinal tracts)
    • contral lat loss of pain, temp (spinothalamic)
  27. presentation of ant cord syndrome
    • loss of motor w spastic paralysis (lateral corticospinal tracts)
    • loss of pain and temp (spinothalamic)
    • preservation of proprioception, kinesthesia, vibration (dorsal columns)
  28. presentation of post cord syndrome
    • loss of proprioception, vibration, pressure, epicritic sensations
    • preservation of motor, pain, light touch
  29. epicritic sensations
    • stereognosis, 2-pt discrim
