Q

primitive reflex; when pt is supine w/ head up on pillows, arms won’t fully extend & legs are in an extensor pattern; Coming to sitting while flexing head, LE’s go into EXT and are difficult to bend; Transfers – if head extends, legs may flex

A

STNR

Q

primitive reflex most often seen post head injury; Extensor tone increases in supine if head is extended; Head pushes into supporting surface; Resistance to shoulder protraction; Rolling blocked by extensor tone; Sitting - when pt extends head, hips slide forward in chair (May slide out of chair)

A

Q

primitive reflex most often seen post TBI; When ball of foot is in contact w/the floor, immediate extensor tone; Not a normal standing position - not conducive to regaining balance and equilibrium; Tx: get either entire foot on floor, or at least heel – do NOT want just balls of foot on floor or will cause this to occur

A

Positive Supporting Reaction

Q

Unintentional movements of hemiparetic limb caused by voluntary movements of another limb or other stimuli; Can be cause by yawning, sneezing, or coughing

A

Associated Reactions
- Raimiste’s Phenomenon = Involved LE will ABD and/or ADD if resistance is applied to the uninvolved extremity; Ex: Supine/Sitting – put pillow between pt’s knees – have them ADD univolved side, & involved will kick in

14
Q

can you use MMT for testing mm strength after stroke?

A
  • Difficult to do due to compensations, spasticity, inability to isolate the muscle; If pt has spasticity – goal is to get functional idea of strength; document “Unable to MMT due to spasticity, but assessed….”
  • MCA - 20% don’t regain use of their UE’s
  • Stroke in General: must keep in mind that only 75-90% of corticospinal fibers cross, so MOST OFTEN you see Contralateral involvement, BUT may have some ipsilateral involvement as well; often we use ‘unaffected side’ as baseline – in these pt’s, ‘unaffected side’ might be weak too

  3. Trunk Impairment Scale

Q

What is pusher syndrome?

A
  • Altered perception of body’s orientation
  • Perceive body as vertical when it is actually tilted 20*
  • Ipsilateral Pushing - active pushing w/stronger extremities toward weak side - Tendency to fall toward weak side
  • visual and vestibular input intact

17
Q

Where is the lesion when pusher syndrome is present?

A

posterolateral thalamus

18
Q

How should a PT intervene for pusher syndrome?

A
  • working in a corner, push towards wall
  • Having something in front of them to make them more aware
  • Mirror – for visual input so they know when they are doing this

(-) poor outcome – difficult to work on interventions if always push to weak side
(+) brain can compensate – generally will; disappear/ decrease around ~6 mo’s

19
Q

What is the difference between an physiological, household, and community walker?

A

1) Physiological Walker- Walks for exercise only at home or during PT sessions ; Likely requires a good amt of help/assistance; in home, may stand to complete some ADL’s (toileting, etc)
2) Household Walker - Uses walking for home activities; Predictable environment; can getting around their house decently, though may use an AD; won’t walk into clinic for a PT session
3) Community Walker - Enter/leave home, ascend/descend curb, and manage stairs independently, Independent w/some community activities

20
Q

Where is a lesion if there is speech and language impairments?

A

cortex of the dominant side

- majority of L sided stroke

21
Q

trouble speaking fluently but their comprehension can be relatively preserved; difficulty producing grammatical sentences and their speech is limited mainly to short utterances; understand speech relatively well

A

Broca’s aphasia

- also known as non-fluent or expressive aphasia

22
Q

form of aphasia the ability to grasp the meaning of spoken words and sentences is impaired, while the ease of producing connected speech is not very affected

A

Wernicke’s aphasia

  • receptive aphasia
  • increase tactile cues; simple sentences; don’t give options; give extra time to respond
23
Q

Mixture of receptive and expressive aphasia

A

global aphasia

- poorer outcomes for rehab

24
Q

difficulty swallowing

A

dysphagia

- mm problem (usually), nerve problem, or both

25
motor speech disorder, indicates movement of jaw and tough impaired
dysarthria | - slurred speech
26
What area of the brain is affected when there are visual-perceptual deficits?
right parietal cortex - S and S: unilateral neglect, agnosia (inability to interpret sensation, therefore difficulty recognizing certain people/ objects/ sounds/ shapes, etc
27
What cognitive deficits are seen following stroke?
1. Attention 2. Memory 3. Perseveration 4. Executive function
28
What effect can a stroke have on a pts emotional status?
1. Pseudobulbar affect - Emotional Lability = uncontrollable emotions; uncontrollable crying or euphoria 2. Apathy - Decreased emotion (may come off as depression, or lack of motivation) 3. Depression - result of both dealing w/ disability + physical effects
29
Where is the lesion that most likely results in depression?
left frontal or right parietal
30
When does depression most often occur following a stroke?
6months- 2 years (lasts/ peaks) | - dealing with life changes due to stroke
31
Which side of the brain is affected: Difficulties w/communication; Negative, anxious, depressed, slower, cautious, uncertain, insecure; More realistic about their problems, very aware of impairments
Left Brain Stroke
32
Which side of the brain is affected: Unilateral neglect; Indifferent, quick, impulsive, euphoric, poor judgment; Overestimate their abilities, often unaware of impairments
Right Brain stroke - safety is major concern - use bed/ chair alarms
33
Which side of the brain is affected: Short attention span; Emotional lability; Irritability, confusion, restlessness; Psychosis, delusions, or hallucinations
Both sides affected
34
What sensation is commonly lost following stroke?
Proprioception - esp. ankle: affects mobility, balance, ambulation, etc - Needs to be in sensory exam! - other sensations are impaired, but rarely absent
35
What is the most common distribution of sensation loss/ impairment?
Face, UE, and LE together
36
What types of pain are often felt following stroke?
1. Thalamic pain (uncommon) - constant severe, burning type of pain; involving PCA usually and parts of thalamus; spinothalamic systems affected; no great way to treat.. some meds 2. shoulder pain - more common; involved side = due to mm weakness (weight of arm on joint) and lack of movement; uninvolved side = overcompensation 3. other joint pain - more common
37
What does bladder function look like in patients with stroke?
1. Incontinence common in acute phase - Catheter should be removed early (UTI) 2. Can by hyper or hyporeflexic bladder later on
38
What are secondary complications due to stroke?
1. Contractures* 2. DVTs & PE* 3. Skin breakdown* 4. Seizures 5. Aspiration 5. Causes issues with dysphagia 6. Problems with speech – swallow eval - KEY is PREVENTION! – PT ROLE, esp. *’d ones; Get pts moving, and early
39
What outcome measures does the neurology section recommend students learn for patients with stroke?
1. 6 MWT 2. 10 mWT 3. Action research arm test 4. Ashworth 5. BBS 6. DGI 7. Fugl-Meyer (motor performance) 8. FRT 9. Orpington Prognostic scale 10. Postural assessment scale for stroke 11. Stroke Impact Scale 12. Tardieu spasticity scale
40
What are outcome measures that asses body structure and function following stroke?
1, Ashworth Scale 2. Orpington Prognostic Scale 3. Fugl-Meyer (motor performance) 4. Tardieu Spasticity Scale 5. FTSST 6. NIH Stroke Scale
41
What are outcome measures that asses activity following stroke?
1. Berg Balance Scale 2. DGI 3. Functional Gait Assessment 4. 10 mWT 5. 6 MWT 6. Action Research Arm Test 7. Arm function 8. Functional Reach Test 9. FIM 10. STREAM 11. ABC - sometimes more difficult for pts to understand
42
What are outcome measures that asses participation following stroke?
1. Stroke impact scale - the pt's perception of where they're at; physical, memory, thinking, etc. 2. SF36
