Approximately 15 million people suffer a stroke annually, of whom around 6.7 million die as a result   . Despite the fact that the mortality rate has decreased in recent decades, stroke remains the second greatest cause of death all over the world  and is one of the main causes of limitations in daily activity defined as disability  . Stroke survivors suffer from a wide variety of disabilities that limit their ability to perform the activities of daily living (ADL), as well as different degrees of physical, cognitive, emotional and social limitation  . As a disabling disorder, stroke can be classified within the framework of the WHO International Classification of Function, Disability and Health (ICF), which encompasses health and health-related domains, disability and disease, impairments, activity limitations and participation restrictions. As the functioning and disability of an individual occur in a context, the ICF includes a list of environmental factors. The ICF is the WHO framework for measuring health and disability  .
Aphasia, which influences most social activities, affects one third of stroke patients  . Aphasia differs in character and content in the various phases after stroke. The severity varies from mild or moderate problems to complete inability to identify or find words, or to speak and understand language, making it impossible to express oneself. The linguistic disorders differ across aphasia types and include difficulty in understanding the meaning of words (semantic disorder), trouble in producing word sounds (phonologic disorder) and problems in constructing sentences (syntactic disorder)  . Difficulties of speaking, writing and reading change the status of persons with aphasia from independence to dependence, sometimes leading to a life dominated by therapy, concentration problems and a drop in material and economic standards, in addition to limited access to information and communication technologies    . The subjective experiences of persons with aphasia seem to be isolation, boredom, bewilderment, fear, anger, shame, apathy, hopelessness, resignation and depression  . Because communication constitutes the key to social participation  , the healthcare services should pay more attention to the delivery of stroke chronic care, where effective rehabilitation strategies are important  . A prerequisite for improving stroke rehabilitation focuses on stroke survivors’ impairments, as many people survive stroke and are forced to continue life with aphasia and communication difficulties. Aphasia strikes like greased lightning, threatening the person’s autonomy, independence and ability to express basic needs. Due to the fact that communication affects most human activities, aphasia rehabilitation should be prioritized from the start and followed up in the chronic stage by a competent community based rehabilitation team to reduce or eliminate activity limitation and restrictions on participation   . Long-term consequences of stroke constitute a top-10 research priority, which includes helping stroke survivors and their families to cope with speech problems  .
Speech problems require rehabilitation, which after stroke is described as long-term and process dependent. Stroke rehabilitation typically entails a cyclical process involving: 1. Assessment, to identify and quantify the patients’ needs; 2. Goal setting, to define realistic and attainable goals for improvement; 3. Intervention, to enable progress towards agreed goals for improvement; and 4. Reassessment, to assess progress towards agreed goals  . An important strategy is to conduct an assessment prior to rehabilitation in the area of communication, in order to reduce the suffering caused by social isolation, activity limitation and participation restrictions, as well as to diminish the consequences of the health burden  . Stroke units with an interdisciplinary rehabilitation team competent in speech and language therapy, medical therapy, nursing, occupational therapy and physiotherapy should be established to provide optimal rehabilitation for stroke patients  . An interdisciplinary approach is essential for the rehabilitation of the patient.
The aim of this review was to investigate the evidence of interdisciplinary teamwork in the rehabilitation of stroke patients with aphasia.
2.1. Review Question
The review question addressed was: How is the process of assessment, goal setting, intervention and reassessment applied by interdisciplinary teams in the rehabilitation of stroke patients with aphasia?
2.2. Search Strategy, Data Sources and Screening
Searches were conducted in online databases (Embase, Ovid Medline, Cinahl, Cochrane Library, Proquest and Web of Science). The following key-words were systematically searched for, both separately and in combination with AND and OR: stroke, aphasia, communication impairment, language tests/hearing test, communication, speech, language, hearing, verbal, evaluation, mapping, assessment, check-up, examination and screening. The first search, which was broad, took place in January 2015 in three databases, Embase, Ovid Medline and Cochrane Library, and resulted in 1206 hits. The second search in March, 2015 was refined and key search terms included: stroke, aphasia, communication, interdisciplinary and rehabilitation. The MeSH headings and free text terms were combined to form the more specific terms mentioned above. An example of the search in one of the main databases, Ovid MEDLINE is presented in Table 1.
Table 1. An example of the search in Ovid Medline
Studies of aphasia due to causes other than stroke were excluded, as were studies conducted before 2005. Two of the authors (S.V., T.O.) assessed the data extracted. A total of 248 titles met the inclusion criteria, of which nine were included for quality assessment. One study  was acquired at the Norwegian Stroke Conference 2015, which we attended. The retrieval process is presented in Figure 1.
2.3. Inclusion and Exclusion Criteria
The inclusion criteria were: 1) peer-reviewed research; 2) published in the English language; 3) studies focusing on the stroke rehabilitation process; 4) studies from the perspective of interdisciplinary teamwork in the rehabilitation process; and 5) studies that focused on experiences of communication with patients with aphasia. Supplements, theoretical frameworks, review articles and grey literature were excluded.
2.4. Quality Assessment
Each identified article was appraised using the PRISMA checklist of items to describe and analyse the quality  . All included articles were reviewed twice by the first two authors, after which they were checked by the third author in order to achieve consensus on the selection.
Figure 1. Flow-chart of the included studies  .
2.5. Data Extraction
The papers were read thoroughly several times by the first two authors (S.V. & T.O.) both separately and together. The content was discussed and reread before data extraction. Data were extracted from the nine papers by systematizing: author, country, year of publication, design, sample, analysis, aim and main findings. Details of the studies included in the review are presented in Table 2, and main findings are highlighted by cursive italic fonts.
2.6. Assessment of Methodological Quality
The methodological quality of the included studies was thoroughly assessed by two of the authors (SV, TKO) using a modified version of the Norwegian Knowledge Centre for Health Services (NOKC) check-list for cross sectional studies  . This check-list is a tool for assessing the degree to which the methodology of the studies encompasses the risk of systematic bias. The check-list contains eight questions assessing: 1. Population, 2. Sampling methods, 3. Comparison of respondents and non-respondents, 4. Response rate, 5. Data collection procedures, 6. Reliability and validity, 7. Statistical methods and 8. Ethical considerations. Studies that fulfilled more than 50% of the criteria were rated as “Acceptable”. Although one study was rated “Low” in terms of methodological quality as the methodology used did not appear to match the check-list criteria, it was deemed important to include its content. When in doubt, we consulted the third author (ES). No studies were excluded due to low quality. Methodological shortcomings mainly concerned criteria 3 and 8, and demonstrated in Table 3.
The nine included studies were analysed and data extracted from them by categorizing the four components of rehabilitation; assessment, goal setting, intervention and reassessment  . The particular shared characteristics of assessment, intervention and reassessments are exemplified in Table 4. Goal setting is presented under sub-heading 3.1.2.
3.1. The Components of Rehabilitation
Opportunities for and barriers to an optimal rehabilitation are interpreted and presented under the following headings; assessment and assessment tools, goal setting, interventions and reassessment. A brief outline of the main positive and negative out- comes of rehabilitation of stroke patients with aphasia is presented in Table 5.
3.1.1. Assessment and Assessment Tools
Assessment tools that explore the whole person are useful for the rehabilitation of language     . In one study, the team members had a collective responsibility for person-centred assessment  . The inclusion of family members and next of kin is valuable for understanding the patient as a person       . The ICF domains are fundamental for the development of new tools  . Assessment of activity, participation and environment is important    . A user-friendly

assessment tool was developed by an international expert panel to standardize follow-up care for stroke patients  . Some assessment tools such as the ACAS were not appropriate for persons with severe aphasia  . Patients with aphasia are likely to be interpreted as having a passive role, therefore withdrawn patients require a more concerted effort  .
In the assessment the main areas of language comprised; auditory, comprehension,

verbal expression, reading and writing  . A variety of assessment tools were described in the included studies. Matos claims there is a need to develop a new assessment tool based on the ICF. It is important to consider all ICF domains in the rehabilitation of stroke patients and their language ability. Healthcare professionals require tools that explore the whole person and the entire situation  . Stroke causes impairment in language, physical ability and emotions. However, Matos claims that the social dimension is often disregarded in the assessment procedure. Tools such as Assessment for living with Aphasia and the Burden of stroke scale are suggested for exploring the situation of the whole person based on ICF domains  . However, such tools are not always appropriate for persons with aphasia. The ACAS, which was developed for inpatients as well as for the home care service in The Netherlands, was found to be unsuitable for patients with severe aphasia because they could be left without rehabilitation goals and relevant interventions  . Even from the start, assessment of patients with communication impairments due to aphasia is likely to be poor. Interdisciplinary team members interpret patients with aphasia to have a passive role  .
A Post-stroke Checklist (PSC) was developed by international medical experts as a user-friendly tool for the identification of long term problems in stroke patients  . Assessment of persons with LIS prioritizes respiratory and nutritional status, communication skills and cognition. Family and next to kin are important for obtaining knowledge about the person  .
Clinicians utilized both formal and informal assessments, as well as discussions with the multidisciplinary team and the patient’s family members  . The main language areas (auditory, comprehension, verbal expression, reading and writing) were assessed. The patient’s decision-making ability was included, especially in acute inpatient and inpatient rehabilitation settings. Assessing mood, communication and cognition was deemed essential  .
3.1.2. Goal Setting
The patients’ views and wishes are vital for defining meaningful goals and the input of family members can be helpful  . WHO goals pertaining to patient rights were not fulfilled, as a lack of information to patients with aphasia was revealed  . Important information on topics such as the causes and effects of stroke, recovery and prognosis, test results and the support available in the future was not provided to patients. Those with aphasia received less information and communication time compared to stroke patients without aphasia  .
Social and emotional well-being was incorporated in the goalsetting by including information and involving families  . The goal for patients with LIS is threefold; to establish and maintain optimal respiration, nutrition and communication  . Quality of life goals became more visible to the members of the interdisciplinary team through the PSC tool  .
It is important to take cognition and fatigue into account to ensure effective interventions  . The PSC tool provides a common platform for performing quality of life interventions  . In order to constantly tailor the interventions they were negotiated both in structural meetings and on the spot  .
In addition to life-supporting interventions, resources for communication and communicative skills such as eye winking should be included. To be able to interpret the patient’s wishes and establish optimal communication, the staff should become familiar with adapting to and utilizing advanced communication equipment, as well as being open minded in the close relationship with the patient  .
A structural referral system to guarantee continuity in long term chronic care is recommended  . The PSC provided the interdisciplinary team with a common referral system to use in the reassessment  .
Both formal and spontaneous reassessment continuously occurred in the form of close negotiations between the members of the interdisciplinary team in order to achieve appropriate goals and interventions. Furthermore, unplanned dialogue took place when it became necessary to reconsider agreed goals  . Reassessment should reveal the communication skills of patients with LIS, their adaptation to advanced technology and whether more support is needed to communicate. Moreover, relevant competence should be harmonized with the needs of patients with LIS  .
3.2. Interdisciplinary Teamwork
Interdisciplinary teamwork is a prerequisite for rehabilitation. The included studies highlight the variety of healthcare professionals involved in the rehabilitation of stroke patients with aphasia. The studies refer to SLTs, rehabilitation assistants, physiotherapists, occupational therapists, SCCs, nurses, nurse assistants, senior care assistants, healthcare assistants, dieticians, medical experts/physicians, social workers, a psychologist, an engineer and technical support. Some studies described next to kin as useful collaborative partners.
3.2.1. Rehabilitation Strategies
SLTs suggest that a broader interdisciplinary team is necessary to apply the ICF framework for patients with aphasia. FMs should be included to optimize the assessment of activity and participation. In Portugal, SLTs traditionally focus on linguistic impairments and activity limitations, and have no tradition of involving FMs  . Matos points out that the British National Stroke guidelines suggest that allied health professionals, health or social care workers and volunteers should have an increased role in an interdisciplinary intervention at the chronicstage of aphasia after stroke. The SLTs perceived such an intervention to be more valuable than previously appreciated. Matos stated that the assessment was performed by SLTs  .
The team members’ roles in the rehabilitation process were unclear  . The four main areas of language were assessed by 51 SLTs in acute and rehabilitation in-patient settings  . GPs might make an important contribution by identifying prognostic characteristics  . Psychologists could have a significant role in the interdisciplinary team due to the need to address the impact of the emotional changes that follow stroke and aphasia  .
Clarke’s study conducted at two stroke units in hospitals in Northern England focused on the close collaboration among team members when caring for stroke patients  . The close interdisciplinary collaboration in terms of sharing knowledge and skills facilitated negotiations (opportunistic dialogue) and led to the best problem-solving care in the rehabilitation of stroke patients. The sharing was both planned (i.e., formal meetings) and unplanned (i.e., seizing the moment). This collaboration went beyond the traditional features of teamwork and greatly benefitted the rehabilitation. In the opportunistic dialoguethe team members experienced person-centred assessment and a collective concern about the person with aphasia, which is an absolute prerequisite for successful rehabilitation. All team members were considered valuable for achieving the rehabilitation goals. By including nurses the study demonstrates that rehabilitation is not only the responsibility of therapy experts  .
Nurses are mentioned as an essential part of the team caring for patients with LIS, as their assessment of the daily care is important. The skilled interdisciplinary team set shared goals, organised follow-up and reassessed skills  . Stroke patients need health information in the acute stroke unit, where three out of seven informants described nurses as the main information providers  .
Stroke nurses specialized in long term care after stroke were responsible for monitoring patients in the rehabilitation process. They set goals alone without involving the other healthcare professionals in the interdisciplinary team  .
Nurses and senior care assistants are the main staff categories in the care of persons with stroke  . These nurses experienced working in isolation with few opportunities for teamwork and expressed a strong need for interdisciplinary cooperation to increase the quality of the rehabilitation  .
3.2.2. Interdisciplinary Cooperation
Patients living at home and their caregivers were referred to different healthcare professionals by the SCCs, but a cooperation strategy in the rehabilitation process was absent  . The rehabilitation team at Sunnaas Hospital in Norway is interdisciplinary and encompasses the different skills needed in the rehabilitation process. The team members considered interdisciplinary teamwork essential for successful rehabilitation. Patients with LIS constitute such a small group that even international teamwork is warranted to facilitate best practice in their rehabilitation  . Joint dialogue-based cooperation strategies are dependent on co-location of core team members, as well as regular meetings with collective thinking and engagement  . Moreover, joint dialogue is problem-oriented and emerges spontaneously due to team members observing problems and seizing the moment to solve them, irrespective of interdisciplinary status. The dialogue is also patient-oriented and closely linked to defined rehabilitation goals. Team members articulate knowledge, values, experiences, perceptions and beliefs  . In this opportunistic dialogue the rehabilitation process is based on negotiations between team members’ perspectives  . One of the benefits of opportunistic dialogue is that teamwork makes it possible to go beyond the traditional focus on structural features. The result is shared competence and effectiveness in the rehabilitation process  . Allied health staff, nurses, health care assistants and therapy assistants worked together in groups of approximately 20 persons. SLTs, a primary care physician and a community continence adviser cooperated and linked the patient to specific referrals by using the PSC  . Interdisciplinary team members interpret patients with aphasia to have a passive role, thus patients with communication impairments are likely to be disadvantaged from the start  .
3.3. Education and Training
There is an unmet need for learning more about interdisciplinary teamwork among senior care assistants and nursing home nurses  . The benefits of interdisciplinary teamwork became more integrated after a staff training programme, which led to team- work competence and job satisfaction  . Allied health staff, nurses, health care assistants and therapy assistants also had formal sessions guided by psychologists, an occupational therapist and SLTs. This training resulted in increased knowledge and confidence, integrated team-working and the holistic management of patients  . An interdisciplinary training programme entitled “Training the trainers” was developed to support fragile communication following stroke and former stroke patients were involved in designing it. The result was less avoidance of communication with patients with aphasia and more support being offered  .
Nursing home staff required more knowledge about interdisciplinary activities  , as well as training and education in stroke assessment, utilizing assessment tools and goal-setting. Senior care assistants needed better skills in communicating with dysphasic patients  , while nursing home nurses requested accredited education  . The interdisciplinary team needs training, while continuity can be ensured by using the same assessment tool and referral system every time. Healthcare professionals require knowledge about how cognition and fatigue influence interventions for persons with aphasia  . Ross’ study developed an interdisciplinary training programme to increase staff knowledge in terms of recognition and basic management of emotional, cognitive and communication problems following stroke  . After completing the programme the interdisciplinary team members reported improved assessment skills and better management of mood, cognition and communication  .
The aim of this review was to investigate the evidence of interdisciplinary teamwork in the rehabilitation of stroke patients with aphasia. The review question addressed was: How is the process of assessment, goal setting, intervention and reassessment applied by interdisciplinary teams in the rehabilitation of stroke patients with aphasia?
As persons with aphasia and their next to kin rate the rehabilitation of communication skills as the most important aspect, it is necessary to identify components and factors that contribute to successful rehabilitation in this area. The goal is to design sustainable and beneficial assessment, goal setting, intervention and reassessment for the rehabilitation of persons suffering from aphasia.
4.1. Making a Difference for Persons with Aphasia
A problem is that healthcare professionals can misinterpret patients who suffer from aphasia after stroke. The aphasia might be understood as a vague response or lack of interest and cooperation  . This misinterpretation on the part of staff members can cause them to devote less attention and interaction time to patients  , and difficulty reaching the point at which to start rehabilitation. Moreover, the emotional stress and social limitation experienced by patients with aphasia can be ignored from the start  . The fact that patients with aphasia are not informed about their status and prognosis might be demotivating for them  . When healthcare professionals’ pattern of care is weak in the area of rehabilitation, it must be strengthened. As communication is a reliable key to social participation, patients with aphasia are dependent on tailored rehabilitation    .
4.2. The Starting Point and the Process of Rehabilitation
Without an appropriate assessment there is no basis for rehabilitation, thus all approaches will be random. As time is a crucial factor, the assessment must start as soon as possible for in-patients  . Competence and confidence are required to make optimal use of the wide variety of available assessment tools. Evidence reveals that knowledge and training are essential for enabling staff members to utilize assessment tools  . Existing assessment tools and the ACAS were not always considered appropriate for stroke patients with aphasia or severe aphasia   . The ICF seems to incorporate relevant factors for the assessment procedure, thus it is necessary to develop a new sustainable assessment tool based on the ICF   . It is challenging to construct a user-friendly tool based on the ICF   . The PSC was intended to focus on long-term assessment with an interdisciplinary approach based on the 11 relevant ICF areas for persons with impairment after stroke  . A prerequisite for successful rehabilitation of persons suffering from aphasia appears to be employing the ICF framework as a base for assessment by operationalizing the main components of functioning, disability and health. There is no doubt that for patients with aphasia, SLTs are the most competent professional category to carry out the assessment, set goals and decide how to intervene. The core improvements for persons with aphasia concern how language is transferred and applied to their real life  . Threats state that the question is how the ICF can contribute to improving the quality of life for persons with aphasia. Environmental factors influence patients’ situation and have an impact on the assessment. The patient’s condition can hinder or promote a successful assessment. Fatigue, depression, hunger, lack of sleep, pain, etc. can make a valid assessment impossible  . As patients with aphasia spend most of their time with nurses and senior care assistants, members of these two professional categories are essential for detecting such factors, thus facilitating a valid assessment.
4.3. Interdisciplinary Team Work
Impairments following a stroke are complex and require a highly complicated and specific rehabilitation, which must be provided by an interdisciplinary care team  . Of the healthcare professionals mentioned as part of the interdisciplinary teams that provide care to stroke patients, SLTs have the highest competence in the area of speech and language impairments. As nurses and nurse assistants spend a great deal of time close to patients with aphasia  , they can facilitate continuity in the assessments, intervention and reassessment. Patients with aphasia receive less attention and are often negatively labelled  . This demands improved awareness and attention on the part of the nurses and nurse assistants to ensure that the patients are seen and communicated with.
This close relationship means that nurses are in a special position to assess the patients and conduct interventions in daily care situations  , thus they have a central role inthe interdisciplinary team. However, stroke unit nurses did not appear to be well integrated in the interdisciplinary team  . There is an urgent need to re-examine the role of nurses in stroke rehabilitation to enable them to make a substantial contribution to the interdisciplinary work  . Nurses are not always aware of this responsibility. In-patients with stroke expected nurses to be the main information provider  . The fact that this is not the case means that there is unused potential in the rehabilitation process.
Different professional categories have a role in supporting the rehabilitation of patients with stroke  . However, the care team does not always function as an operational interdisciplinary team   . While the interdisciplinary approach appears to function for patients with severe sequelae, our findings reveal that it tends not to function as well for patients with milder complications      . The question is which priority is given to active interdisciplinary rehabilitation for the group with milder complications and whether the team is designed to be goal oriented. Inefficient rehabilitation strategies could result in unused potential and reduce the patients’ chances of regaining their ability to communicate. The time at which the intervention takes place and the amount of training are important for successful rehabilitation of aphasia after stroke. To achieve the best possible result, the whole team, including nurses and nursing assistants, must collaborate closely with each other and actively motivate, guide and stimulate the patient. Utilizing periods when the patient is awake, alert and motivated is crucial for success as it enables the amount of training to be increased and exercises to be transferred to different situations.
In our opinion, a successful rehabilitation team for persons with complications after stroke, especially those who suffer from aphasia, is one that collaborates closely and is co-located. Being unable to express oneself must be so full of hopelessness and fear that interpreting and facilitating rehabilitation best practice in stroke units and the community health services should be a high priority for closely collaborating interdisciplinary teams. To achieve this all health professionals, including nurses, must be integrated in the team, seize the right moments, take responsibility and interpret their role as important for the rehabilitation. A prerequisite for successful further rehabilitation in the community health service is the design of functional interdisciplinary teams that include nurses and nursing assistants.
4.4. Education and Training
A need for more education and training was one of the major findings in this review      . Studies show that the level of staff competence influences how patients with aphasia are communicated with  -  . A skilled team increases confidence and safeguards the quality of the rehabilitation process for stroke patients    . Results reveal greater confidence in communication with patients, use of assessment tools and in interdisciplinary collaboration after completion of a training programme   . Staff members exhibited greater recognition and acceptance of the patients’ speech problems, frustration and distress. Care for families and next of kin strengthened mutual collaboration and improved rehabilitation   . Competence in using devices and confidence in the shared goals and strategies facilitated collaborative practice and improved the overall outcome for the person with aphasia  .
Another way of increasing competence involves sharing professional knowledge by working in opportunistic dialogue  . In the team, the effect of learning and working together by sharing core skills led to a common understanding instead of professional defence. The whole team was aware of and shared the patients’ goals, thus the members made a concerted effort to work towards them together, leading to successful rehabilitation. Sharing knowledge in the team increased motivation and engagement, while alternative ways of conceptualizing the rehabilitation interventions proved beneficial for patients  . Work satisfaction and enthusiasm make staff desirous for training  .
Some studies mentioned experiences of designing and running training programmes  . To achieve a really practical and useful content, one study described how former stroke patients were recruited to assist in designing the training programme, as well as presenting some parts of it  . This was evaluated as a success.
5. Limitations of the Study
This systematic review has some limitations. The number of included studies is few. After reviewing the literature search it turned out that our research question limited the amount of research that could be included due to the need for research on persons with aphasia. Although this review has been thoroughly evaluated by two of the authors (SV and TKO) who read the studies several times from different perspectives, there is still a possibility that we might have missed out on or misunderstood some of the information presented. To counter the possibility of undetected bias, differences in understanding and judgment were resolved by discussions between the authors, leading to a common understanding of, as well as consensus on, the interpretation of the analysed studies. Although some of the included qualitative studies have a small sample, we consider that it would be difficult to perform large studies on this topic as persons with aphasia constitute such a limited research field. The stroke research field is strong in terms of research from a neuroscience perspective, but poor from the perspective of aphasia rehabilitation. In our opinion, smaller in-depth studies can produce valuable and easily transferable information in this area.
Ignoring the rehabilitation of communication for patients with aphasia could influence the quality of the rest of their lives and become the difference between boredom or interest, inactivity or activity, social isolation or participation, dependence or independence and apathy or hope. This study highlights the need for one valid and reliable assessment tool that incorporates communication problems. Successful rehabilitation starts with the application of a relevant assessment tool. Assessment tools require tailored competence in order to fully exploit the starting point and subsequent steps of the rehabilitation process. Interdisciplinary collaboration towards shared goals in the rehabilitation of language is decisive for success. Each professional category in a successful rehabilitation team has a defined role. To perform as a successful team, co-location and close collaboration are crucial.
The studies in this review reveal that nurses’ position in post-stroke care is unclear and limited. To achieve a valid assessment and successful rehabilitation, the roles of interdisciplinary team members and their collaboration strategies must be reorganized. The contribution of nurses and senior care assistants must be acknowledged as important for continuity, successful assessment and rehabilitation as a whole.
A need for formal and informal education, both on site and accredited, was detected. The design of relevant educational programmes should be the responsibility of universities and other educational institutions. Community health services, hospital stroke units and educational organisations should collaborate to design relevant training programmes. In addition, this review revealed a need for increased knowledge and skills among interdisciplinary team members in terms of interdisciplinary team work. Persons with aphasia should be more involved in their own rehabilitation process, which implies the necessity of educating interdisciplinary team members to communicate with them.
