16
Q

Dysarthria

A

Biomechanical issues
Weakness, decreased ROM
Not really aphasia

17
Q

Cognition and behavior in vision after stroke

A

Visual problems
- Homonymous hemianopsia: effects ½ the visual field of both eyes a patient with left hemianopsia will have visual loss on the nasal field of the right eye and the ear side of the left eye
Unilateral neglect
Perceptual issues
Cognition
Psychosocial/Behavioral
- Depression
- Anxiety
- Altered sex drive
- Altered appetite
- Avoidance of social
- Personality changes

18
Q

CVA assessment

A

We often get these folks very early in the process-2-7 days after!
- Initial Assessment in Field (FAST)
- Degree of the CVA (see NIHSS on Canvas)
It is the worst it will be
Not a progressive disorder, but can get worse if they just sit
Typical recovery
- 3-6 months to return
- Lifetime to improve

19
Q

Functional Assessment Scale

A
20
Q

Assessing CVA clients with top down approach

A

Functional
ADL Assessment
Environmental assessment

21
Q

Assessing CVA clients with bottom up approach

A

Balance and Mobility
- Berg
- Tinetti
- Timed Get up and Go
- Functional Reach
- Wheelchair Skills
Upper Limb
- ROM
- Subluxation
- MMT
- Tone assessment
- Box and Blocks
- 9-hole peg test
- Perdue

22
Q

Modified Ashworth Scale

A
23
Q

Upper limb assessment

A

More Top Down in Nature
- Action Reach Arm Test
- The hand function test
Bottom up
- 9-hole peg test – precision, tip pinch, manipulation
- Perdue peg board - precision, tip pinch, manipulation
- Minnesota Dexterity test – more precise gross dexterity
- Box and Blocks - originally used to assess median nerve damage, but also looks at gross dexterity; least precise gross dexterity
- Range of motion
- Strength
- Sensory function: pain, temp, light touch, moving/constant, touch localization, stereognosis
- Tone

24
Q

Cognitive/Vision and Psychosocial Assessments

A

Fugle-Meyer
ADL Assessments
Cognitive Assessments
- Orientation
- Kolman or Cognitive Assessment
Vision
- Perceptual tests
- Acuity
Specific Issue
- Executive Function Performance Test
- Grocery Shopping Assessment
- Others

25
Q

Treatment options for stroke

A

Rehabilitative/Remedial
Compensatory and adaptive
or both

26
Q

Timeline after stroke

A
  1. Stroke occurs
  2. Hyperacute - first 24 hours
  3. Acute - 1-7 days
  4. Early subacute - 1 week - 3 months
  5. Late subacute - 3-6 months
  6. Chronic - 6+ months
27
Q

Acute stage of stroke

A

Positioning
Dysphagia management
Fall preventions and safety
- Teaching transfers
- Very basic ADLS
Early mobilization and function
Preparing the client for rehab

28
Q

Rehabilitation stage of stroke

A

Goal is restorative
- By remediation or adaptation
ADL training and equipment
- Motor learning
- Addressing safety
Task oriented training
CIMT - Constraint Induced Movement therapy
Combined with cognitive strategies
- Mental practice (MP)
- Mirror therapy (MT)
- Virtual reality
- Action observation (AO)
- Strengthening and exercises and functional tasks
* Grading and adapting
* NMES

29
Q

Special issues with CVAs

A

Once they have active movement, you don’t have to worry about subluxation.
Spasticity and hemiplegic shoulder pain
Limited evidence that slings prevent subluxation
Aggressive ROM results in increased incidence of painful shoulder, gentle ROM is preferred
Ultrasounds not helpful, use NSAIDs
Functional e-stim may help reduce or prevent subluxation, but doesn’t appear to reduce pain
Deinnervation of subscapularis may reduce shoulder pain and improve PROM
Some evidence that massage aromatherapy and acupressure can reduce shoulder pain
Oral corticosteroids appear to improve shoulder-hand syndrome for at least the first 4 weeks
Mirror therapy can reduce pain associated with shoulder hand syndrome.

30
Q

General stroke safety

A

Medical status
Cardiac and respiratory precautions
Fall risk
Subluxation
Skin
Swallowing
Impulsive - don’t trust them

31
Q

Handling upper limb after stroke

A

Teach patient as early as possible proper positioning
Use gait belt or draw sheet instead of pulling on arm
Orthotics as needed
Avoid motions above 90 degrees unless there is scapular mobility
- No overhead pulleys
Encourage touching and handling of the extremity by the patient
- Self range
Use the limb

32
Q

Bed position to avoid subluxation after stroke

A
