Stroke in Canada
-Leading neurological cause of death in Canada Prevalence
- There are between 40,000 to 50,000 strokes in Canada each year
- About 300,000 Canadians are living with the effects of stroke
- After age 55, the risk of stroke doubles every 10 years
- A stroke survivor has a 20% chance of having another stroke within 2 years
- For every 10,000 Canadian children under the age of 19, there are 6.7 strokes
Stroke in Canada
Cost
- Stroke costs the Canadian economy $2.7 billion a year
- The average acute care cost is about %27, 500 per stroke
- 58% of stroke patients return home after their stroke
- Many experience depression, as do up to 30% of caregivers

Types based on mechanism of damage (two types of strokes)
- Ischemic (most common)
- ->thrombosis (blood clot formed in the vessels of the brain)
- Embolism (blood clot formed somewhere else) - Hemorrhage (bleeding)
Ischemic Stroke
- Approx 80% of all strokes
- Blockage in artery with in brain because of blood clot or other substances
- Atherosclerosis = Narrowing of arteries caused plaque build up
Types of Ischemic Stroke
- Permanent Symptoms
2. Trainent Symptoms
Transient Ischemic Attack (TIA)
- Short-time (symptoms resolve in less than 24 hours)
- No permanent symptom
- Warning sign for impending major stroke (10-15% within 3 months)
Hemorrhagic Stroke
- Accounts for approximately 20% of cases
- Weakened blood vessel that ruptures and bleeds into surrounding brain
- Has greater mortality than ischemic stroke
- The blood accumulates and compresses the surrounding brain tissue
MRI of Ischemic and Hemorrhage
Ischemic (black in one area, acute)
Hemorrhage (white spots over more area)
How are the symptoms different?
Hemorrhagic: in addition to other stroke symptoms, will likely experience a sudden onset headache or head pain — a warning sign that might not occur during ischemic stroke.
Stroke symptoms: numbness or weakness on one side of the body or face, trouble speaking and difficulty with vision or balance.
Neurological impairments following stroke
- hemiplegia
- hemianopsia
- Aphasia
- Somatosensory deficits
- Incontinence
- Apraxia
- Depression
- Dysphagia
- Cognitive and perceptual deficits
Recovery
of every 100 people who have a stroke
- 10 recover completely (10%)
- *25 recover with a minor impairment or disability (25%)
- *40 are left with a moderate to severe impairment
- *10 are so severely disabled they require long-term care (10%)
- 15 die (15%)
*our patients
75% of 40,000 to 50,000 strokes in Canada each year = 33750 per year added to OT workload
Recover from stroke
- Brain recovery
- Neuroplasticity
- Improvement of performance components
- Adaption
Timeframe for recovery
- Golden time: first 1 to 3 months
- Gradual improvement for 1 year - up to 5 years
- Most independent in basic ADL
- Many are unable to return to work (depends on other factors)
Medical management
acute care
- Determining the cause and site
- Preventing progression
- Reducing cerebral edema
- Preventing secondary medical complications
- Treating acute symptoms
Medical management
-Acute ischemic stroke
- Restoration of blood flow
- Antithrombotics: aspirin and heparin
- Thrombolytics: dissolve the blood clots
- Thrombectomy: surgery
Interdisciplinary team approach
who are the members of the team
- Attending physician
- Resident
- Nurse
- Nutritionist
- Social worker
- Speech pathologist
- OT

Common lines and drains in ICU
1. Foley catheter:
to drain urine, avoid clamping the catheter, bag should be at a lower level than the patient’s bladder
Common lines and drains in ICU
2. External ventricular drain:
- to drain CSF
- you can change the head of the bed or mobilize the patient, only if clamped by the nurse.
Common lines and drains in ICU
3. Intracranial pressure monitoring catheter (ICP):
measures intracranial pressure for patients who had swelling and elevation of the intracranial pressure
-Passive therapy, positioning and splinting NO ADLs at this point
Common lines and drains in ICU
4. Spinal drain to drain CSF:
when the drain is open the patient should be flat in bed
-Can do ADL and move around only if the drain is clamped
Common lines and drains in ICU
5. Intravenous line (IV):
-they are superficial. Do not put pressure on them specially avoid splinting the area
Common lines and drains in ICU
6. Feeding tubes:
a) Nasogastric (NG)
b) Percutaneous endoscopic gastrostomy (PEG)
- While feeding make sure the head of the bed is raised 30 degrees to prevent aspiration
Initiating OT
- Check to make sure there is an order for OT. Check every session.***
- Ask the nurse if the information is current
- Review medical records: Is there a reason for holding the therapy: change in mental status, deep vein thrombosis, pulmonary embolism
- Check the facility standards
- Start with gross assessment of:
- vital signs: if there is great discrepancy, report to the nurse
- mental status
- movement/strength
How to work with a person in ICU
-Studies show that early OT and PT in ICU is safe
Monitor:
- Vital signs (document before, middle and after treatment)
- Changes in the neurological symptoms (posture, speech, pupils, …)
- Subjective complaints
-f any problems happen: terminate the treatment and inform medical team immediately
What can be done in acute phase (assessment and intervention)
-fill in later
Functional activities suggested in bed
1. Rolling to affected side

Functional activities suggested in bed
2. Rolling to the unaffected side
- Passively guide the affected side
- Increase awareness of affected side
Functional activities suggested in bed
3. Maintaining side lying

- Use a roll towel under waist to give stretch to muscle
- Used rolled towel in mid-thoracic spine to hold the position
Functional activities suggested in bed
4. Bridging
- To strengthen the back and hip extensors
- To be used for transfers and dressing
Functional activities suggested in bed
5. Side lying on the affected side towards sitting

- Patient needs help to start
- Side lying on the unaffected side towards sitting
Bed positioning
On back: pillow under affected arm and neck
Lying on affected side: leg straight pillow under unaffected leg, pillow between affected arm and unaffected arm, pillow supporting back
Lying on unaffected side: leg straight: pillows under affected leg, pillows under affected arm, pillows behind back for support
Weight Bearing activities:
-On upper limb
- in side lying
- while sitting (arm partially extended)
- infront of the sink
- Stabilizing objects
Weight Bearing activities:
-On lower limb
- Bridging
- Sitting at the edge of the bed, both feet on the floor
- Early transfer when medically stable
Graded sitting and standing activities:
1. Supported sitting in bed
- Raise the head of the bed gradually to 30 to 40 degrees and then to 80 degrees
- Start activities like
- ->grooming
- ->feeding
- ->leisure activities
- ->upper body dressing
Graded sitting and standing activities:
2. Supported sitting in a chair
- To increase out of bed sitting tolerance
- Use pillows
- Watch shoulder alignment
- Self-care, visual scanning, weight bearing
Graded sitting and standing activities:
3. Unsupported sitting in bed
- Can be in crossed leg position
- Head of bed is elevated but not touching the person’s back
- Pillows against the bed rail to protect the patient
Graded sitting and standing activities:
4. Unsupported sitting at the edge of the bed with feet dangling
- ***Safety first
- ensure equal weight bearing
- Postural control increases by touching the floor
Graded sitting and standing activities:
5. Sit to stand/Transfers

Maintain skin integrity
Develop wearing schedule - better at night than day time
Types of Splints:
- Resting hand splint
- Cone splint
- Adjustable inflatable splint (for patients with >1 stroke and increased muscle tone)
- Blanket/towel roll (roll around elbow to prevent elbow flexion)
Edema
cause and management
Cause: Blood clot or IV infiltrate Talk to nurse Edema management: -positional elevation -Extended limb above the heart level -Active and active assistive ROM -Note: Compression garments is not appropriate for IV related problems
Question: is raising foot rests of the wheelchair a good idea for managing edema in lower limbs: NO
-unless it is a tilt chair and then the legs can be higher than the heart
Shoulder Management
Aim and steps
- Educate the team to avoid pulling on the extremity
- Signage on the bed: (Please do not pull on patient’s arm. Please contact occupational therapy at 555-555-5555 with questions and concerns
- Supine: Suport shoulder in protraction and elbow and fingers in extension
- Edge of the bed: support on bed side table
- Out of bed in chair: support with pillows or an arm support
- Active and passive ROM : make sure scapula is moving with passive and active movement (glenohumeral rhythm)
Note 1: no use of slings in ICU as the person will not be moving
Note 2: if using IV on radial artery avoid wrist flex and ext
Raising spatial Awareness
- TV
- Phone
- Food
- Bed position to face the hallway
- Use bright coloured hand bands
- Family pictures
- More verbal cues
- Use less verbal cues as the person improves
Early cognitive management
ICU psychosis:
Contributing factors
ICU psychosis: -Fluctuating state of consciousness-fatigue, distraction, confusion, disorientation, restlessness, fear, anxiety, excitement, hallucination and delusion
Contributing factors: sleep problems, stress, sensory overload and underload, immobilization, not able to differentiate between day and night
Early cognitive Management
OT intervention:

How it impacts each part
-Starts with pain and continues to stiffness in shoulder and hand
Shoulder: loss of ROM with abduction, flexion and external rotation
Elbow: usually no signs or symptoms
Wrist: intense pain during extension and dorsal edema tenderness during deep palpation
Hand: edema over metacarpals, no tenderness
Digits: moderate fusiform edema, intense. pain during flexion in MC and PIPs, loss of skin lines
Shoulder-hand syndrome
stages

Consequences of dysphagia
Dehydration
->dry mouth, constipation, urinary tract infection, confusion, severe illness, or even death
Consequences of dysphagia
Malnutrition
–> weight loss, reduced energy, skin breakdown, impaired wound healing, and lower resistance tp infection
Consequences of dysphagia
Aspiration
-entry of saliva, food, liquid, or refluxed stomach contents) –>respiratory problems, and pneumonia
Consequences of dysphagia
Choking:
blockage of airway by piece of food, making it difficult or impossible to breathe
How to help with dysphagia
1. Proper positioning
- Sitting in chair or in bed (60 to 90 degrees)
- Head in middle and flexed slightly forward
- Encourage to stay upright about 30 min after meals
How to help with dysphagia
Reduced distractions
- Avoid clutter at the table
- Quiet environment
- no visitors at meal time
- Taking medication before or after meal rather than during
How to help with dysphagia
Adjust feeding rate, amount and texture
- Small, frequent meals
- Use teaspoon not a tablespoon
- encourage them to swallow twice
- Check for laryngeal elevation when swallowing which is the movement of the adam’s apple up and down
- Ensure the mouth is clear before introducing more food
- Use thickened liquids/ soft or pureed foods
How to help with dysphagia
Teach the person to:
- Eat slowly, and never rush
- Monitor slef-feeding with a mirror
- Remove pocketed food with their tongue
- Be aware of drooling and use a napkin if necessary
- Cough to clear the throat
- Wear loose-fitting clothes and avoid tight belts, to avoid reflux
