24
what is the modified ashworth scale for tone?
0 = no increase in tone 1 = slight increase in catch and release 1+ = slight increase in catch and resist 2+ = marked increase in tone but easily moved 3+ = passive motion difficult 4+ rigid
25
The modified tardeiu scale uses R1 and R1 to define tone, what does each of these values represent
* R1 - angle of muscle reaction to fast stretch * R2 - full PROM - angle of muscle reaction to slow stretch
26
how do you get the dynamic tone component of a muscle?
Modified Tardeiu Scale (R2 - R1 = x)
27
Describe synergy as three tenants
* loss of fractionated movement in a predictable pattern * 2 synergies per limb * appears with volitional movement
28
Describe the UE flexion synergy
* Scap retraction and elevation * GH ABER * elbow flexion and supination * wrist and finger flexion
29
Describe the UE extension synergy
* scap protraction * GH ADIR * elbow extension and pronation * wrist and finger flexion
30
when someone has spasticity and moves in synergy, the spasticity pattern will \_\_\_\_\_\_\_\_
dominate the movement at the SHOULDER and FOREARM
31
What is the dominant synergy pattern of the UE? LE?
* UE - flexion * LE - extension
32
Describe the LE flexion synergy
* Hip FABER * Knee flexion * Ankle DF and inversion
33
Describe the LE extension synergy
* Hip EXADIR * Knee extension * Ankle PF and inversion
34
which two movements/muscle groups are difficult for stroke patients to recover
finger extensors and ankle everters
35
what is learned non-use
Acutely after CNS injury, there is no reward for efforts using the extremity, so we stop trying to use it, leading to risk of delayed recovery.
36
Four reflexes that may arise as a result of CNS injury
ATNR, STNR, STLR, and PSR
37
what are associated reactions?
movements that occur as a result of a sneeze, cough, etc.
38
What is Souques Phenomenon?
An associated reaction that may be therapeutic: elevation of the hemi UE above horizontal with the elbow extended may elicit finger ext/abd
39
What is Raimiste's Phenomenon
an associated reaction that may be therapeutic: resistance to abd/add on either side produces the same phenomenon on the other side
40
what is homolateral limb synkinesis
an associated reaction that may be therapeutic: mutual dependency between hemi limbs (i.e. flexion of the R UE elicits flexion of the R LE.)
41
T/F: spasticity is a contraindication to Therex
false
42
what outcome measure would be best to assess strength in a stroke (hemi) patient?
Fugl-Meyer
43
T/F: The patient may demonstrate associated reactions even during the flaccid stage
true
44
How do you tell the difference between a UMN and LMN lesion affecting the face?
UMN will knock out contralateral upper and LMW will knock out ipsilateral - in other words, UMW will spare the lower face
45
How do you tell the difference between CB and sensory ataxia?
A true CB ataxia will be considerably worse if the patient is asked to close their eyes
46
Four ways to test to ataxia/coordination
RAM, dysdiadochokinesia, finger to nose, heel to shin
47
classic categories of apraxias most often seen with L hemi
* ideational (can't understand task, tools, or sequence) * ideamotor (understand but can't execute, may spontaneously use tool correctly)
48
what does the parietal lobe do
visuospatial processing and internal representation of spatial relationships for successful imitation of gestures
49
what is a good outcome measure to use to assess balance in the stroke population
miniBest
50
what are the three types of aphasias
* fluent - Weirnicke's receptive aphasia * nonfluent - Broca's expressive aphasia * global - impaired comprehension and expression
51
About ⅓ of stroke patients have depression but its more common in which hemisphere of CVA?
L CVA
52
what is a secondary neurological impairment that may impact mental status during treatment over time? (uncommon)
hydrocephalus
53
what percentage of stroke patients 6-12 months can ambulate independently w or w/o AD?
up to 80%
54
T/F: Most strokes spontaneously recover in 3-6 months
true
55
National Average LOS at IRF
14 days
56
what happens in the hours (up to a week) following a stroke
resolution of ischemic prenumbra
57
what happens in days-months after a stroke
resolution of diaschesis (area distal to infarct impacted by miscommunication from effected area)
58
what is the order of CNS reorganization following a stroke
* neurotransmitter alterations * inhibition release of ipsilateral alternating pathways * synaptogenesis
59
why do we start with the trunk
proximal neurological redundancy as well as “stability aids mobility”
60
T/F: pharmocologic intervention is the only method that has lasting/long term impact on tone
true
61
8 ways to facilitate movement
1. resistance 2. quick stretch 3. tapping 4. stroking 5. joint approximation 6. joint traction 7. icing 8. voice (sharp, loud)
62
5 ways to inhibit unwanted movement
1. prolonged stretch 2. sustained pressure 3. slow rocking/rotational movement 4. warmth 5. voice (quiet, soothing)
