Service
organisation and the delivery of rehabilitation are typically focused in the
first months of stroke and often fail to meet the long-term and evolving needs
of people with stroke. Over time the nature of rehabilitation will shift from
restorative to compensatory and adaptive approaches but rehabilitation should
not end solely because natural recovery appears to have reached a plateau.
difficulties that can
occur after stroke affecting personal, domestic and extended activities
of daily living (e.g. work and driving)
help the person with
stroke to engage in independent living and social participation.
Personal
activities of daily living (PADL)
basic activities such as washing, dressing,
bathing, going to the toilet, eating and drinking;
Extended
activities of daily living (EADL)
encompass both domestic and community
activities such as shopping, cooking and housework that allow complete
or virtually complete independence.
These activities also enable community and
social participation.
Driving
it influences self-esteem and mood.
healthcare professionals need to discuss and
give advice on fitness to drive.
The current UK regulations regarding driving
are available online (
https://www.gov.uk/government/publications/assessing-fitness-to-drive-a-guide-for-medical-professionals).
Work
and leisure
this refers to two related but different
types of activity: productive work (paid or voluntary) and leisure
activities.
people with stroke may require specialist
advice and support to enable them to resumethese activities.
Arm
function
approximately 70% of people experience
altered arm function after a stroke, and this persists for about 40% of
survivors.
interventions used in routine practice to
improve arm function and those that might help deliver repetitive and
functionally relevant practice.
Apraxia
·difficulty performing purposeful actions due to disturbance
of the conceptual ability to organise actions to achieve a goal.
·people with apraxia often have problems carrying
out everyday activities such as dressing or making a hot drink despite
adequate strength and sensation.
·they may also have difficulties in selecting the
right object at the right time or in using everyday objects correctly.
Apraxia can be detected using standardised tools (e.g. Test of Upper Limb
Apraxia [TULIA]) and is usually associated with damage to the left cerebral
hemisphere.
Attention
and concentration
disturbed alertness is
common after stroke especially in the first few days and weeks, and more
so in non-dominant hemisphere stroke.
attention impairments may persist in
the longer term and may be specific (e.g. focusing, dividing or
sustaining attention) or more generalised, affecting alertness and speed
of processing and be evident in poor engagement or general slowness.
attention problems may
lead to fatigue, low mood and difficulty with independent living.
Executive
function
refers to the ability to
plan and execute a series of tasks, inhibit inappropriate automatic
impulses, regulate emotional responses, foresee the consequences of
actions and make judgments about risk.
‘dysexecutive syndrome’ encompasses
various impairments, including difficulties with problem solving,
planning, organising, initiating, inhibiting and monitoring behaviour.
these can be detected
using standardised tools (e.g. the Behavioural Assessment of the
Dysexecutive Syndrome [BADS]).
executive functions rely
heavily upon attention and are associated with deficits in everyday
function and independence.
Spatial
awareness
problems with spatial
awareness (also referred to as visual spatial neglect, sensory
inattention etc.) refer to a reduced awareness of some part of the
person’s body or their environment.
it is more common in people with
non-dominant hemisphere stroke (typically causing left -sided neglect)
and those with hemianopia.
behavioural symptoms
include bumping into objects on the affected side or only reading one side
of pages in newspapers or books.
neglect can be detected
using standardised assessments ( e.g. the Behavioural Inattention Test).
Weakness
and ataxia
stroke frequently results
in weakness, lack of co-ordination of movement (ataxia) and loss of
selective movement.
weakness on one side of
the body (hemiparesis or hemiplegia) is a hallmark of stroke, affecting
around 80% of people with stroke. It causes substantial disability,
mainly through limiting mobility but also in affecting arm function.
ataxia occurs in around 3%
of ischaemic strokes, principally in cases involving the cerebellum but
also as a consequence of severe sensory dysfunction (known as sensory
ataxia).
Examples of standardised
measures of motor impairment include the Motricity Index and the Scale
for the Assessment and Rating of Ataxia (SARA).
Balance
many people experience
difficulty with balance after stroke.
this is usually due to a
combination of reduced limb and trunk motor control, altered sensation
and sometimes centrally determined alteration in body representation
such that the person misperceives their posture in relation to the
upright.
impaired balance reduces confidence and
increases the risk of falls on walking.
Falls
and fear of falling
people with stroke are at
high risk of falls at all stages in their recovery.
stroke-related balance
deficits include reduced postural stability during standing and delayed
and in co-ordinated responses to both self-induced and external
perturbations.
gait deficits include
reduced propulsion at push-off, decreased hip and knee flexion at
swing-phase and reduced stability at stance-phase.
the high incidence of
falls may be attributable to impairments of cognitive function, motor
weakness, dual tasking and the planning and execution of tasks.
non-stroke factors that
increase the risk of falling in older people (e.g. multiple medications)
are also common in people with stroke.
falls may have serious physical and
psychological consequences, including an increased risk of hip fracture
(usually on the weaker side) and greater mortality and morbidity
compared to people without stroke.
fear of falling may lead to decreased
physical activity, social isolation and loss of independence.
interventions to prevent
falls include education and adaptations e.g. low bed, chair alarms and
are often multi-factorial, addressing physical and psychological
aspects.
Walking
the highest priority for
many people with limited mobility after stroke is to walk independently.
the treatments and
equipment aimed at improving walking and includes exercise.
orthoses are external
devices that support or enhance an impaired limb; commonly used after
stroke are ankle-foot orthoses (AFOs) to support a hemiplegic foot and
ankle.
Spasticity
and contracture
spasticity can cause
discomfort or pain for the person with stroke, difficulties for carers
and is associated with activity limitation.
spasticity is common,
especially in a non-functional arm- estimates of prevalence vary from 19%
to 43% depending on the timing of assessment.
any joint that does not
move frequently is at risk of developing shortening of surrounding
tissues leading to restricted movement and this is referred to as a
contracture, and is not uncommon in limbs affected by spasticity.
contractures can impede
activities such as washing or putting on clothes, and may also be
uncomfortable or painful and limit the ability to sit in a wheelchair or
mobilise.
Splinting
the process of applying a
prolonged stretch through an external device, most commonly splints or
serial casts, to prevent or treat contractures.
Splinting is used to help
manage tone, reduce pain and improve range of movement and function
(passive and active). Standardised measures for ease of care and
resistance to passive stretches include the Arm Activity measure and
modified Ashworth Scale respectively.
According to a new national guidelines for stroke,
rehabilitation plays an important role in recovery.It highlights thatthe frequency of therapy must enable stroke
patients to meet their rehabilitation goals and therapy should continue as long
as patients are willing and capable of participating and showing measurable
benefit from treatment.
The
National Clinical Guideline for Stroke pays attention into an early
mobilisation. Those who are medically stable but with difficulties to move soon
after a stroke should be offered frequent, short, daily mobilisations (45 min)
and it should start between 24 and 48 hours after a stroke.
A stroke
unit must be capable of providing rehabilitation to all its patients, providing
a specialist early supported discharge service, so stroke patients can continue
their rehabilitation at home.
Commissioners
are recommended to look for specialist rehabilitation services which meet the
specific health, social and vocational needs of people with stroke of all ages.
And they should commission services capable of delivering specialist
rehabilitation in out-patient and community settings, in liaison with inpatient
services.
Why
earlier, more frequent, and higher dose of out-of-bed sitting, standing, and
walking activities are consider to be more effective than previously thought?
The
research ‘Efficacy and safety of very early mobilisation within 24 h of stroke
onset (AVERT): a randomised controlled trial’ answers to above question very
well. It says that the very early mobilisation intervention significantly
reduced the odds of a favourable outcome 3 months after stroke compared with
lower dose usual care starting, on average, 5 h later.
The
biological rationale underlying the potential for early out-of-bed training centres
around three arguments: (1) that bed rest negatively affects the
musculoskeletal, cardiovascular, respiratory, and immune systems,and
might slow recovery; (2) that immobility-related complications are common early
after stroke at a time when patients are very inactive; and (3) that there
might be a narrow window of opportunity for brain plasticity and repair, and
the optimum period for change could be early after stroke. Prompt start and
more episodes of out-of-bed activity might therefore improve outcome.
Early
Physiotherapy in intensive care
Positioning
·
to reduce
skin damage, limb swelling, shoulder pain or subluxation, and discomfort,
·
to
maximise function
·
to
maintain soft tissue length.
·
to
reduce respiratory complications
·
avoid
compromising hydration and nutrition.
Recommendations
Patients
with acute stroke should have an initial specialist assessment for
positioning as soon as possible and within 4 hours of arrival at
hospital.
Healthcare professionals responsible
for the initial assessment of patients with acute stroke should be
trained in how to position patients appropriately, taking into account
the degree of their physical impairment after stroke
When lying or sitting, patients with
acute stroke should be positioned to minimise the risk of aspiration and
other respiratory complications, shoulder pain and subluxation,
contractures and skin pressure ulceration.
Early mobilisation
·
significantly reduced the odds of a
favourable outcome 3 months after stroke compared with lower dose usual care
starting, on average, 5 h later.
Recommendations
Patients with difficulty moving after
stroke should be assessed as soon as possible within the first 24 hours
of onset by an appropriately trained healthcare professional to
determine the most appropriate and safe methods of transfer and
mobilisation.
Patients with difficulty moving early
after stroke who are medically stable should be offered frequent, short
daily mobilisations (sitting out of bed, standing or walking) by
appropriately trained staff with access to appropriate equipment,
typically beginning between 24 and 48 hours of stroke onset.
Mobilisation within 24 hours of onset should only be for patients who
require little or no assistance to mobilise.
