28
Q

_____is the main determinant in individuals with more severe gait deficits

A

Balance

29
Q

______is the main determinant in individuals with more mild deficits

A

Cardiovascular fitness

30
Q

Slow-flexed walker characteristics

A

Excessive hip and knee flexion in midstance
Inadequate dorsiflexion in swing
Forward trunk lean

31
Q

Slow-Extended Walker (Circumduction) characteristics

A

Quads too weak to support the knee during stance phase

Glut Max retracts femur into knee hyperextension to for stance limb support

Ankle PF spasticity

Hip hike and circumduction occur for foot clearance
Usually require an assistive device

32
Q

Fast Walker characteristics

A

Lack of heel rise in terminal stance due to inadequate PF strength

Knee hyperextension in stance to compensate for lack of heel rise to allow the body to progress forward on the forefoot

Step length is compromised due to lack of transition of momentum from unaffected side

33
Q

Moderate Walker characteristics

A

Increased weakness of plantarflexors

Weakness in hip extensors (glut max) and knee extensors (quads)

Greater knee flexion in mid stance

34
Q

Independence in ADLs post-stroke is predicted by…

A

Age
Stroke severity (NIH stroke scale)
UE paresis

35
Q

NIHStrokeScale

A

0
No stroke symptoms
1-4

5-15
Moderate stroke
16-20
Moderate to severe stroke
21-42
Severe stroke

36
Q

Orpington Prognostic Scale

A

Total score ranges from 1.6 – 6.8

Higher scores indicate a more severe stroke and a worse prognosis

37
Q

Proportional Recovery model

A

Uses the Fugl-Meyer outcome measure for UE to predict UE recovery,

In 3 to 6 months, the majority of patients (recoverers) are estimated to recover a fixed proportion, between 0.55 and 0.85 (average ~ 70%), of their potential recovery. A minority of patients (non-recoverers) show only very moderate improvement, which cannot be linked to potential recovery

38
Q

PREP model

A

Algorithm that predicts functional recovery of UE at 3 months. The algorithm is based on the evidence that sparing of descending white matter pathways is related to better recovery of upper limb function after stroke. It has good predictive value but requires the use of neurophysiological and neuroimaging assessment

39
Q

PREP-2 algorithm

A

does not need MRI, instead uses NIHSS to predict UE recovery at 3 months post-stroke. If you do not have TMS score, you still can make some predictions.

40
Q

If patient’s SAFE score is >5 when using PREP-2 algorithm…

A

you don’t need TMS to predict recovery

41
Q

If patient’s SAFE score is < 5 when using PREP-2 algorithm…

A

if NIHSS is <7, then recovery could be good<>limited
If NIHSS is >7, then can be Good or poor, but you can lean more towards poor

42
Q

IV tPA

A

IV tPA should be administered to all eligible acute stroke patients within 3 hours of last known normal . BP should be maintained <180/105 mm Hg for at least the first 24 hours after IV alteplase treatment.

43
Q

Patients ≥18 years should undergo mechanical thrombectomy with a stent retriever if they:

A

Have minimal prestroke disability

Have a causative occlusion of the internal carotid artery or proximal middle cerebral artery

Have a National Institutes of Health stroke scale score of ≥6

Have a reassuring noncontrast head CT (ASPECT score of ≥6)

If they can be treated within 6 hours of last known normal. No perfusion imaging (CT-P or MR-P) is required in these patients.

44
Q

Unilateral spatial neglect can occur with a lesion in any of the following areas:

A

Posterior parietal cortex
Frontal lobe
Cingulate gyrus
Striatum
Thalamus

45
Q

Action-Intentional Disorders

A

Motor neglect,

Not a deficit of the motor pathway, but rather a failure or decreased ability to move in the contralesional space (space contralateral to the damaged hemisphere) despite being aware of a stimulus in that space.

46
Q

Inattention unilateral spatial neglect

A

Sensory neglect,

Lack of awareness, or decreased awareness, of sensory stimulation in the contralesional hemispace.

This decreased sensory awareness occurs even though the sensory pathways and the primary sensory cortical areas are intact

47
Q

Restitutive Approach for USN

A

aim to alter the underlying cognitive impairment. More often used in the early stage of the stroke pathway when plasticity is thought to be greatest

48
Q

Compensatory Approach for USN

A

emphasis on coping with and finding ways of adapting to existing impairments. More often used in later stages of the stroke pathway

49
Q

Top-Down Approach for USN

A

Requires awareness of the disorder.

Aim to train the person to voluntarily compensate for their neglect

Methods include training in scanning and usually provide feedback

Focus on the level of disability rather than impairment.

50
Q

Bottom-Up Approach for USN

A

Do not require awareness of the disorder.

Aim to modify underlying factors, i.e. to alter the impaired representation of space.

Prism-wearing and prism adaptation training are popular recent examples of a bottom-up approach

51
Q

Pusher Syndrome prognosis

A

Only 6 months after a stroke, pathological pushing behavior is rarely still evident.

Pusher syndrome thus has a good prognosis and does not seem to negatively influence the outcome of rehabilitation.

52
Q

Pusher syndrome treatment ideas

A

perform treatments in upright position, do no correct passively instead use verbal and visual cues for patient to actively correct themselves. Focus on midline and verticality is key, patients need to see their deficits

53
Q

King-Devick test

A

Developed to assess eye movement in children with reading difficulty, quantifies saccadic movements and has been proposed for both oculomotor assessment and acute diagnosis in patients with concussion.

Due to variability in performance, patients require a baseline measurement for valid post-injury comparison

56

59
Q

MST strategies for problem recognition

A

watching videos of someone else doing the task at hand, and demonstrating how they overcame their failures

60
Q

MST strategies for problem solving

A

Self-reflection activities - self-prediction of performance prior to performance and self-evaluation following performance

61
Q

MST strategies for decision making

A

allow for errors safely -> self-recognition of errors (if not happening, provide timely feedback) -> encourage to develop self correction strategies for future use -> practice with multiple reps -> generalize strategies for similar tasks
