Flashcards in Exam 3- Stroke part 1 Deck (70):

A stroke usually ___ but can ___

~usually appears suddenly

~can appear slowly


Some of the slow appearing strokes (2)

  1. ~TIAs,
    • pin stroke,
    • mini strokes
  2. ~hemorrhagic


2 main types of strokes

Ischemic/ Occlusive and Hemorrhagic


what is the most common type of stroke and by how much?

80% of strokes are occlusive


Hemorrhagic- some details (2 things associated with it)

~High blood pressure

~Associated with headaches


Hemorrhagic- Common types (5)

  1. ~berry aneurism
  2. ~AVM (arteriosus venous malformation)
  3. intracerebral hemorrhage
  4. cerebral hemorrhage
  5. subarachnoid hemorrhage


Hemorrhagic- what is berry aneurism?

an out pouching of the circle of willis


Hemorrhagic- what is AVM? (stands for and what it is)

abnormal connection of the artery and vein

(AVM = arteriovenous malformation)


Hemorrhagic- 3 courses for an aneurism

  1. It never bursts
  2. It is detected and fixed before it bursts
    • Pick up on a scan when looking for it
    • Pick it up on a another scan (looking at something different) 
  3. ~it bursts and pt has CVA


2 ways to fix an aneurism

Clip and coil


Clip for an aneurism: when can it be used and how invasive is it?

  • ~can be used for an aneurism that has or has not burst
  • ~Need a craniotomy


Coil for an aneurism:

when can it be used?

what does it do?

and how invasive is it?

  • ~for people for not ruptured~
  • a birds nest of wire that fills the hole
    • ~will cause the body to fill back in the aneurism
  • ~Do not need a craniotomy


Hemorrhagic- how does it injure the brain? (5)

  1. ~cell starved of blood distal to bleed
  2. ~pressure on cells right at the site; usually occlude broken artery
  3. ~pressure away from the site; can act like a contra coup injury
    1. ~other arteries can be occluded
  4. ~may have uncal herniation and/or
  5. midline shift


Hemorrhagic- four typical characteristics of pt in PT

  1. ~wide spread injury/problems
  2. ~will be hard to decide where their symptoms came from
  3. ~will be younger
  4. ~rarely will fully recover


Occlusive- 2 types




Occlusive- what is Thrombolytic

Build up of plaque, etc that will cause a blockage in the artery


Occlusive- what is Embolytic?

Blood/plaque/ air/ fat/cancer breaks off and moves (and plugs the artery)


Occlusive- Embolytic- blood clot, three characteristics of emergency treatment

  1. the easiest embolytic occlusion to treat
  2. ~We can do a good a good job getting rid of blood clots with TPA tissue plasminogen activators- thins blood and gets rid of blood clots
  3. ~need to give tPA to someone within 3 hours
    • ~More than 3 hours, the structures distally already starting to die
    • ~Its not worth the risk to thin the blood that much after 3 hours


Occlusive- Embolytic- fat bock: what is a common source?

can caused post surgery



what does it stand for?

what defines it?

Transient ischemic attack

defined by: symptoms resolve within 24 hours


Six characteristics of a Major stroke

  6. ~Much harder for pt to return to function


Three characteristics of a minor stroke

  1. ~Still the same person you were before- personality stays the same
  2. ~Steppage gait; foot drop; some limb paresis
  3. ~A little sensory or motor deficit; distal portion of the UE or LE


What is a shower stroke?

what is a common cause?


(3 points)

  1. ~Lots of little strokes all over
  2. ~Occlusive, sometimes when a clot breaks off a lot of little clots will break off too
  3. ~Can occur after surgeries when you are trying to prevent/correct for a stroke-
    1. endarterectomy (plaque build up in the carotids)
    2. ~The plaque can lead to a shower stroke if all the plaque is not sucked up


some Diagnosis Tests to test for possible stroke (3)

  • ~Echocardiogram- did it happen from a build up of blood settling in the heart
  • ~CT/ MRI

Recovering from a stroke: what are some things that are going on that are helping (4)

  1. Blood flow
    • ~Angiogenesis,
    • collateral blood flow helps with recovery
    • ~Thinning the blood,
  2. keeping the inflammatory response down
  3. ~Pts are going to sleep a lot!
  4. ~Neuroplasticity- need stimulus (we will help to cause it) to help cause new connections and strengthen the old ones
    • ~Have to start moving them fast so that something will start to form in the brain


Recovering from a stroke: what is something that will help if they are flaccid?


what should you be careful of?

  1. ~go into weight bearing to cause compression in jts
  2. ~will get them to have muscle firing
  3. ~Be careful to make sure that when you are doing this that the pt is in proper alignment so that they do not have impingements later

Roods techniques- Inhibitory

~To decrease the threshold ~relaxation


Roods techniques- 3 type of Stretch techniques

  1. ~quick
  2. ~repetitive
    • ~CMP (continuous passive motion)
  3. ~Prolonged


Roods techniques- Quick Stretch:

what is it/how does it work?

facillitaive or inhibitory?

  • ~will jar the muscle a little bit to cause a contraction
  • ~facilitative


Roods techniques- repetitive stretch

what is it/how does it work?

facillitaive or inhibitory?

Repetitive stretch

  • can place a vibrator over the muscle belly
    • > 100 Hz is Facilitatory
    • < 100 Hz is Inhibitory
      • CPM, continuous passive motion, fits in this category


Roods techniques- CPM stretch

what is it/how does it work?

facillitaive or inhibitory?

continuous passive motion stretch-

it is a type of repetitive stretch using < 100 Hz

  • it is inhibitory (< 100 Hz)


Roods techniques- prolong stretch

what is it/how does it work?

facillitaive or inhibitory?

  • ~Serial casting-
    • you will put the person at the end range, recast and move them farther into the range
    • ~trying to get spasticity to release



Roods techniques-  three Jt manipulation types

  1. ~traction
  2. ~low grade manipulations
  3. ~approxiations


Roods techniques- Jt manipulation Traction

what is it/how does it work?

facillitaive or inhibitory?

creates space and relaxes muscles



Roods techniques- Jt manipulation Low grade

what is it/how does it work?

facillitaive or inhibitory?

movements relax muscles/reduce pain (grade 1-2)



Roods techniques- Jt manipulation Approximation

what is it/how does it work?

facillitaive or inhibitory?

compression in joint causes co-contraction of surrounding muscles



Roods techniques- Cutaneous touch types (2)

  1. ~Quick touch
  2. ~Maintain touch


Roods techniques- Cutaneous touch light/quick

what is it/how does it work?

facillitaive or inhibitory?

Cutaneous Touch (must have sensation there)

  • light stroke usually helps with posture
    • touch over the muscle belly- contracts the muscle



Roods techniques- Cutaneous touch maintained


what is it/how does it work?

facillitaive or inhibitory?

Cutaneous Touch (must have sensation there)

  • Maintaining touch will relax muscle (with a little pressure is nice)
    • same way that swaddling works (and tight clothing in peds rehab)
    • Hug
    • calmed the muscle- relaxation



Roods techniques- 2 Ice types

~quick strokes



Roods techniques- Ice quick

what is it/how does it work?

facilitative or inhibitory?

 quick cutanious strokes causes contraction




Roods techniques- Ice prolonged

what is it/how does it work?

facilitative or inhibitory?

If you leave ice on skin long enough it causes relaxation



Roods techniques- Heat

what is it/how does it work?

facilitative or inhibitory?

heat Relaxes them

inhibitory (never used to provoke muscles)

facilitative or inhibitory?

inhibitory (relaxes us)


Roods techniques- Vestibular: spinning

facilitative or inhibitory?

causes contractions



Roods techniques- Vestibular: bouncing on the ball

what is it/how does it work?

facilitative or inhibitory?


Bouncing on the ball (could either excite or inhibit)

  • ~Softly- relaxes (inhibitory)
