Post-stroke rehabilitation
The aim of stroke rehabilitation is for the patient to regain the best level of health, activity and participation possible
within the limits of any persisting stroke impairment.
Many stroke survivors are left with significant changes to physical, emotional, cognitive and social function and about
half of patients who survive for six months will require some help with daily living (bathing, dressing, toileting, feeding
and mobility). Stroke survivors are at risk of physical complications such as falls and long term psychological and emotional
problems. Ongoing management of complex needs is often required after discharge from hospital.
Recovery of function following a stroke varies depending on the part of the body affected. Depending on the severity
of the stroke, maximum functional improvement in paralysed limbs is seen within two to six months. In contrast improvement
of speech, domestic and working skills and unsteadiness can continue for two years or more. Early rehabilitation uses
techniques that focus on neuroplastic change, and later rehabilitation encourages adaptive responses and coping strategies.1
The organisation of hospital services to provide specialised Stroke Units is the most important advance in stroke care.
Best outcomes are associated with specialist multidisciplinary in-patient care in a stroke unit and with therapy that
commences immediately or within days after a stroke. Patients who receive care in a stroke rehabilitation unit are more
likely to be alive, independent and living at home (NNT = 33, 20, 20 respectively) than patients who receive non-specialist
care or care within a general rehabilitation unit.2 The benefits of stroke unit care are seen for all ages,
genders and across the range of severity.3
Stroke survivors require regular follow up after discharge
Leaving hospital after a stroke can be a frightening and difficult experience. This is often the time when stroke survivors
suffer the greatest feeling of abandonment as well as facing a diversity of ongoing problems as they adapt to the longer
term impact of the stroke.
General practice is ideally placed to undertake comprehensive reviews and coordinate best care in the community. Primary
care follow up should be scheduled within the first few weeks following discharge from hospital, and then regularly at
intervals appropriate to the clinical need.
Follow up should address:
- Information and education: enquire about information needs and access to voluntary organisations, peer support etc
- Secondary prevention: reinforce lifestyle changes and check medicine treatment for secondary prevention ( see BPJ
26, March 2010, “Secondary stroke prevention)
- Physical needs: review the impact of the stroke on activities of daily living, and need for further referral, practical
aids and rehabilitation
- Emotional and other hidden needs: screen for depression, pain, continence and sexual issues
- Social and carer needs: review the care plan and address the carer’s needs
Best practice tip: On receiving a discharge letter, following
a hospital admission for stroke, schedule a consultation with the patient and carer/whānau either in the surgery
or at their home. A double appointment may be beneficial and consider whether a joint home assessment with the rehabilitation
team is possible, especially in cases involving significant disability.
Assess the need for advice, information and peer support
Receiving information after a stroke is one of the most important needs reported by stroke survivors and their carers,
even years after the stroke. Face to face discussion is highly valued and can be backed up with written material.
The Stroke Foundation has a free public helpline and provides information through literature and videos and their website.
Field officers are located nationwide and many areas have stroke support clubs. Meeting with other stroke survivors and
carers provides invaluable social support, experiential knowledge and a social comparison.4

Review physical needs
Physical and practical problems with everyday living are common following a stroke. Although the major part of physical
recovery following a stroke occurs in the first six months, functional improvements in activities of daily living and
fitness (lessening of disability or handicap) often continues long after specific neurological deficits have ceased to
change. Most stroke survivors value opportunities for greater independence.
Because there is such a wide area of health and potential disability to assess, as well as responding to the main concerns
of the stroke survivor and carer, it is helpful to have a structured way to check for any areas of difficulties. The following
approach may be useful:
- Ask the stroke survivor and carer to fill out a simple checklist prior to the consultation to indicate any problem
areas and help guide priorities.
An after stroke checklist is available
for download from here
Talking through the activities of a normal day in a chronological sequence provides a simple systematic approach to
identifying problem areas e.g. getting up in the morning, personal hygiene and toileting, dressing, breakfast and other
meals, activities and leisure.
Screen for silent problems such as depression and pain
Some problem areas may not be apparent during a routine consultation, unless already highlighted on a self-completed
checklist. It is recommended to assess for depression, anxiety, dementia and pain, and discuss topics that may cause embarrassment
such as incontinence, physical intimacy and sexual intercourse.
Review the care plan and address the carer’s needs
When consulting with stroke survivors it is important to consider the needs of the carer and whether the care plan is
appropriate. Has the stroke survivor been discharged home to a distressed relative and too little help? The impact of
the stroke on a partner or spouse can be devastating. Carer strain, anxiety and depression are very common after stroke.5
Together with stroke survivors, carers need information and long term practical, emotional, social and financial support.
The carer can often need as much input as the stroke victim; ranging from counselling to cope with the changes in their
life, to respite care to allow them a break. Closer medical supervision may also be required as often carers are elderly
and have their own medical problems.
Who to refer to for stroke related problems |
When stroke related problems arise key specialists for referral for ongoing rehabilitation
include:
- Continence advisors for incontinence assessment and treatment
- Dietitians for advice on healthy eating, especially if poor swallowing or artificially fed, under or overweight
or diabetic
- Occupational therapists for help with independence in all daily activities including self-care (personal care),
leisure and work, including driving assessment where appropriate
- Orthotics service to help correct abnormality or assist function of a disabled limb
|
- Physiotherapists for any movement difficulties, fitness, falls prevention and musculoskeletal complications such
as shoulder pain
- Podiatrists for foot care especially if difficulty caused by paralysis or spasticity
- Psychiatric and neuropsychology support for depression, mood swings, personality changes, and dementia assessment
and support
- Specialist clinics such as pain or spasticity clinics
- Speech and language therapists for difficulties with communication, cognition and swallowing
|
Practical tips for problems associated with stroke
Key references: New Zealand Stroke Foundation “Life after stroke”6 and Australian National Stroke
Foundation “Guidelines for stroke rehabilitation and recovery”.7
Continued exercise and therapy improves movement
Weakness on one side (hemiparesis) is often the single most disabling factor after stroke.8 Reduced movement,
weakness, clumsiness, impairment to balance and changes in tone all impact on the simple ability to move e.g. in bed,
to roll, sit up, stand and walk.
Stroke survivors should be encouraged to be as physically active as possible, maintain walking and return to usual activities.
Even after the initial recovery, further improvement may be seen with ongoing exercise, practice of activities of daily
living and outpatient/community therapy.9 National guidelines recommend that all stroke survivors with activity
that has deteriorated since discharge (six months or later) should have access to further targeted therapy to recover
any ground lost (e.g. physiotherapy, occupational therapy, speech therapy, psychologist).
Stroke survivors are at much greater risk of falls and of serious injury
Falls are more common in people after stroke compared to age-matched controls. Over one-third of stroke survivors will
fall in the first year.10 Risk factors for falls are similar to those for older people in general. In stroke
survivors there is a relationship between falling and depression but it not known whether the depression increases the
risk of falling or if falling increases depression in this group.10
Stroke is strongly associated with secondary osteoporosis, similar to other neurologically incapacitating disorders.11 Stroke
survivors who do fall are at increased risk of injury compared with the general population (8% stroke survivors compared
to 3% general population),12 particularly hip fractures (relative risk for hip fracture within two years of
stroke is 1.4 [95%CI, 0.92 to 2.07]).13
Best practice tip: screen for falls risk and osteoporosis
risk (FRAX) in all patients after stroke. Consider treatment with calcium, vitamin D and bisphosphonates.
For further information see:
Spasticity in the arm or leg following stroke should not be routinely treated
Spasticity is not a major determinant of physical impairment therefore, spasticity that is not interfering with a stroke
survivor’s activity or personal care, does not require treatment.
Consider treatment if spasticity is causing abnormal posturing or involuntary spasms that interfere with activity, discomfort/pain,
or difficulties in personal care, e.g. hand hygiene in a flexed hand.14
- First line treatment is physical therapies such as stretching and dynamic splinting15 (physiotherapy referral).
- Intramuscular injection with botulinum toxin may be effective16 and is available via specialist stroke
and rehabilitation services where other specialist therapies can also be considered.
- Oral anti-spasmodics, e.g. baclofen are not recommended for routine treatment. They provide marginal benefit, if any,
for this indication and are associated with high levels of adverse reactions.17
Improving independence in personal care, around the home and getting out
At six months post stroke, about half of patients are partially or totally independent in their activities of daily
living such as bathing, dressing, toileting, feeding and mobility. By one year this has increased to about two-thirds
and further recovery in function is often seen long after neurological deficits have ceased to change.18
Being able to complete everyday activities as independently as possible is important for most stroke survivors. Stroke
survivors who have limitations on any aspect of activities of daily living can be referred to occupational therapy, for
advice on coping with the disabilities and information on available aids, equipment, and home or work adaptations as required.
No driving within one month after a stroke
After a person has had a stroke, they should not drive for at least one month.19
After this time if there is doubt about driving fitness due to residual disability, a driving assessment by an occupational
therapist trained to provide off road and/or on road assessments should be undertaken.
For more information see: “Medical aspects of fitness to drive”,
available from www.nzta.govt.nz and BPJ
26 (Mar, 2010) ”Driving rules and assessment in older people”.
Driver licences are generally not granted on Class 2, 3, 4 or 5 licences (heavy transport/passenger endorsement) following
a stroke. However, if the stroke survivor has made a complete recovery and has a supporting report from a specialist neurologist
or physician, then the possibility of a return to driving can be considered by the Licensing Agency.
Ask stroke survivors if they are experiencing pain
Pain after stroke is common and is seen in up to 50% of survivors.20 All patients should be asked if they
are experiencing pain.
There are numerous possible causes of the pain. Two main types to consider are:
- Musculoskeletal pain from immobility and abnormal posture is particularly common in people with arthritis, spasticity
and contractures. A subtype of musculoskeletal pain is shoulder pain. This is seen in up to 80% of stroke survivors with
upper limb weakness in the first year after stroke.21 Musculoskeletal pain may improve with physiotherapist
advice and improved handling techniques, posture and movement. Treat with simple analgesics and increase, as necessary,
up the World Health Organisation (WHO) analgesic ladder. Musculoskeletal pain that is not controlled may require referral
for specialist treatment.
For further information see BPJ
16 (Sep, 2008) “Pharmacological management of chronic pain”
- Up to 8% of stroke survivors experience central post stroke pain (CPSP).22 This is felt as a superficial,
unpleasant burning, lancinating or pricking sensation. It is often made worse with touch, water or movement. If there
are no contraindications the first line neuropathic analgesic for CPSP is a tricyclic antidepressant such as nortriptyline.23 Other
options are anticonvulsants and opioids. CPSP that is poorly controlled within a few weeks should be referred to a specialist
in pain management.
For further information see BPJ
16 (Sep, 2008) “Pharmacological management of neuropathic pain”
Fatigue may improve with treatment of disrupted sleep, depression, anxiety and pain
Many stroke survivors report substantial fatigue and describe it as the most difficult symptom they have to cope with.24 Fatigue
may affect mood, cognition and communication, worsen physical symptoms and the ability to participate in activities and
increase risk of falls. It is multifactorial in origin.25
Management consists of:
- Providing reassurance that fatigue is usual after stroke
- Planning daily activities to allow for regular rest periods
- Treating associated conditions such as disrupted sleep, depression, anxiety and pain
- Screening for other medical causes of fatigue e.g. anaemia, hypothyroidism, sleep apnoea

from: www.stroke.org.nz/pdfs/resources/SF2116FatigueLR.pdf
Nutritional problems are common in people who have had a stroke
To identify adults who are at risk of malnourishment or are malnourished, the Malnutrition Universal Screening Tool
(MUST) is recommended. Referral to a dietitian or to a speech and language therapist, for swallowing problems, may be
required.
For further information see BPJ 15
(Aug, 2008) “Strategies to improve nutrition in elderly people”.
MUST is available from: www.bapen.org.uk
Control of bladder and bowel often improves over time
In the acute post-stroke period faecal and urinary incontinence is very common. A proportion of stroke survivors continue
to have problems (20% have urinary incontinence six months post stroke) and incontinence is one of the key reasons for
referral to long term care.26
The causes of incontinence are multifactorial. Faecal incontinence is often associated with constipation and overflow.27 The
three most common reasons for urinary incontinence are urge incontinence, urinary retention and functional incontinence.
Diagnosis of incontinence is based on the history, examination (including rectal examination), and possible further
investigations. Treatment depends on the cause (Table 1). In the community setting patients may be referred to a continence
adviser. Where continence is not achieved, containment aids, e.g. pads, can be used.
Table 1: Summary of treatment strategies for incontinence28 |
Type of incontinence |
Management strategies |
Faecal (often associated with constipation) |
- Rectal examination
- Minimise use of medicine with anticholinergic properties e.g. antipsychotics, TCAs, oxybutinin, antiemetics
- Review hydration and dietary fibre
- Laxatives
- Bowel training e.g. daily routine to promote defaecation
|
Urge incontinence |
- Bladder retraining e.g. scheduled voiding regimen
- Anticholinergic medicines e.g oxybutinin
|
Urinary retention with overflow |
May be aggravated with constipation and anticholininergic medicines. If severe, consider
urinary catheterisation (intermittent if practical)
|
Functional incontinence (unable to toilet successfully because of problems with cognition,
communication, mobility, undressing, etc) |
Usually requires a multidisciplinary approach |
Take the initiative to talk about sex
Sexual dissatisfaction is very common after stroke but rarely discussed unless prompted by a health professional.
Psychological and interpersonal factors may include lack of communication, diminished self esteem and sense of attractiveness,
depression, fatigue, fear of sexual failure or fear of causing a stroke.29 These factors have a significant
influence on sexual intimacy and compound the physical problems after stroke such as difficulty with positioning, anorgasmia
and erectile or lubrication difficulties.
Sildenafil (a PDE5 inhibitor) may be used with caution to treat erectile dysfunction post stroke. Contraindications
are very recent stroke (less than two weeks), unstable cardiovascular conditions and concomitant use of nitrates.
For further information see BPJ 12
(Apr, 2008) “Erectile dysfunction”
Information on intimacy after stroke is available from the Stroke Foundation: www.stroke.org.nz/pdfs/resources/Sexuality-Booklet.pdf
Mood and emotions
Psychological and emotional issues may be significant after stroke even when there has been good physical recovery.
Key issues are recognising and coping with the limitations caused by the stroke, grief for what has been lost, fear of
another stroke, generalised anxiety, frustration and depression and coping with stigma and social isolation.30
One-third of stroke survivors develop depression or an anxiety disorder
Regularly screen for depression and anxiety in stroke survivors. Depression is very common in people who have had a
stroke. At six months post-stroke approximately one-third to one-half of stroke survivors will be depressed31 and
3 to 9% will have major depression.32 Similar figures occur for anxiety.33
Treatment strategies for stroke related mood disorders are similar to those for the general population. Stroke survivors
with depression or anxiety that does not respond to standard measures, is causing distress and is interfering with recovery,
should be assessed by an expert e.g. clinical psychologist, psychiatrist.34
For more information see:
Emotional lability may be treated with antidepressants
Stroke survivors who have exaggerated changes in mood such as uncontrollable laughing or crying, or heightened irritability
or anger, may be experiencing emotional lability.35 Antidepressants, such as SSRIs, are first-line treatment
to lessen the frequency and severity of outbursts and reduce anger.36
Dementia is very common after stroke
Around 10% of people will be diagnosed with incident dementia soon after a new stroke. More than one-third of stroke
survivors will have a diagnosis of dementia after recurrent stroke. Dementia and cognitive impairment post-stroke usually
requires detailed cognitive assessment and a full multidisciplinary re-assessment such as referral to stroke team or psychogeriatrician.
