ABSTRACT

Acute dizziness and vertigo are common emergency department presentations (≈4% of annual visits) and sometimes, a life-threatening diagnosis like stroke is missed. Recent literature reviews the challenges in evaluation of these symptoms and offers guidelines for diagnostic approaches. Strong evidence indicates that when well-trained providers perform a high-quality bedside neurovestibular examination, accurate diagnosis of peripheral vestibular disorders and stroke increases. However, it is less clear who can and should be performing these assessments on a routine basis. This article offers a focused debate for and against routine specialty consultation for patients with acute dizziness or vertigo in the emergency department as well as a potential path forward utilizing new portable technologies to quantify eye movements.

ABSTRACT

BACKGROUND: Existing data suggested a rural-urban disparity in thrombolytic utilization for ischemic stroke. Here, we examined the use of guideline-recommended stroke care and outcomes in rural hospitals to identify targets for improvement. METHODS: This retrospective cohort study included patients (aged ≥18 years) treated for acute ischemic stroke at Get With The Guidelines-Stroke hospitals from 2017 to 2019. Multivariable mixed-effect logistic regression was used to compare thrombolysis rates, speed of treatment, secondary stroke prevention metrics, and outcomes after adjusting for patient- and hospital-level characteristics and stroke severity. RESULTS: Among the 1 127 607 patients admitted to Get With The Guidelines-Stroke hospitals in 2017 to 2019, 692 839 patients met the inclusion criteria. Patients who presented within 4.5 hours were less likely to receive thrombolysis in rural stroke centers compared with urban stroke centers (31.7% versus 43.5%; adjusted odds ratio [aOR], 0.72 [95% CI, 0.68-0.76]) but exceeded rural nonstroke centers (22.1%; aOR, 1.26 [95% CI, 1.15-1.37]). Rural stroke centers were less likely than urban stroke centers to achieve door-to-needle times of ≤45 minutes (33% versus 44.7%; aOR, 0.86 [95% CI, 0.76-0.96]) but more likely than rural nonstroke centers (aOR, 1.24 [95% CI, 1.04-1.49]). For secondary stroke prevention metrics, rural stroke centers were comparable to urban stroke centers but exceeded rural nonstroke centers (aOR of 1.66, 1.94, 2.44, 1.5, and 1.72, for antithrombotics within 48 hours of admission, antithrombotics at discharge, anticoagulation for atrial fibrillation/flutter, statin treatment, and smoking cessation, respectively). In-hospital mortality was similar between rural and urban stroke centers (aOR, 1.11 [95% CI, 0.99-1.24]) or nonstroke centers (aOR, 1.00 [95% CI, 0.84-1.18]). CONCLUSIONS: Rural hospitals had lower thrombolysis utilization and slower treatment times than urban hospitals. Rural stroke centers provided comparable secondary stroke prevention treatment to urban stroke centers and exceeded rural nonstroke centers. These results reveal important opportunities and specific targets for rural health equity interventions.

ABSTRACT

Health equity is a fast emerging priority for most healthcare systems around the world. Factors impacting health equity include education level, geographical location, age, gender, employment status and income. However, research examining the effect of these demographic variables on health service utilisation among mid-aged and older post-stroke adults is limited. Data was obtained from a sub-study of the Sax Institute's 45 and Up Study, which is conducted in Australia. The sub-study survey collected demographic, health service utilisation and health status information from 576 participants who had a previous stroke diagnosis. Poisson regression was used to examine the association between demographic characteristics and number of consultations with a doctor and/or an allied health practitioner over a 12 month period. All demographic measures were significantly associated with the number of consultations with doctors and/or allied health practitioners. The number of doctor consultations increased for those who struggled to live on their available income (IRR = 1.41), but decreased for females (IRR = 0.81), those who reside in an inner regional area (IRR = 0.83), those who were separated, divorced or widowed (IRR = 0.61), and for those who completed a trade, apprenticeship or diploma (IRR = 0.83). The number of allied health practitioner consultations increased for those who completed a trade, apprenticeship or diploma (IRR = 1.27), and for those who struggled to live on their available income (IRR = 1.38), but decreased for increasing age (IRR = 0.87), females (IRR = 0.78), and for those who reside in an outer regional or remote area (IRR = 0.49). We identified several demographic factors associated with a lower frequency and type of health care services used by post-stroke adults. These possible barriers need to be explored further, as reduced use of healthcare services may lead to poorer stroke outcomes in these demographics. Specifically, researching strategies to best support individuals facing these additional challenges is necessary to ensure equitable healthcare for all Australians.

ABSTRACT

BACKGROUND: Neurological emergencies are one of the major diagnosis groups in the Emergency Medical Services (EMS) with the highest rate of misdiagnosis. Despite the knowledge of time sensitivity and the importance of prehospital factors, prehospital delay is common. Although several stroke triage scales have been developed, a gold standard in the prehospital setting is lacking. OBJECTIVES: Our aim was to evaluate the perception of neurological emergencies by EMS personnel and to identify current problems, difficulties and opportunities for improvement in the prehospital management of stroke, seizure, non-specific neurological symptoms, and paediatric neurological emergencies. METHODS: The study was conducted as an online survey through SoSci Survey and was made available from March 1st to June 30th 2023 to all personnel working in emergency medical services. The access link was distributed through snowballing, social media, and through a QR code on a promotional poster. The survey was completed anonymously. The final survey consisted of 30 questions in German on the topics of neurological emergencies, general neurological assessment, specific neurological examination including paediatric assessment, stroke, and seizures, and finally suggestions for improvement. RESULTS: The largest group of participants were paramedics, who estimated to encounter neurological emergencies at a general rate of 20-60%. When unease was felt, the main reasons were ambiguity of symptoms and insufficient admission capacity of hospitals. The biggest challenges were highly varied. Almost 80% of participants assumed that the neurological assessment would be omitted in difficult patient groups such as demented, intoxicated or children. 75% felt uncomfortable making a paediatric assessment, 50% were unfamiliar with the Paediatric Glasgow Coma Scale. CONCLUSIONS: Support through more standardized practical training and defined, uniform guidelines is needed. There was also a clear need for peer collaboration, feedback and case sharing. Digitalization, the usage of telemedicine and updated versions of the documentation protocols including paediatric adaptations to current guidelines could further improve current neurological assessment in the prehospital setting.

ABSTRACT

The nervous, endocrine and immune systems are interconnected through neurotransmitters, endocrine hormones and cytokines, forming a neuro-endocrine-immune (NEI) network that outputs effect information to target organs in a multi-level and multi-system manner. The effects of acupuncture can be amplified through the NEI network, causing local microenvironment responses at acupoints to treat post-stroke depression (PSD). This paper systematically elucidates the mechanisms of acupuncture treatment for PSD from three aspects: nervous, endocrine and immune, and reveals the potential mechanisms and biological pathways of acupuncture treatment for PSD from an overall perspective based on the NEI network, aiming to provide a reliable theoretical basis for fundamental research on acupuncture treatment for PSD.

ABSTRACT

OBJECTIVES: To observe the effect of electroacupuncture on miR-142-5p and ADAMTS1/PI3K/AKT pathway in rats with ischemic stroke, so as to explore the regulatory mechanism of electroacupuncture on angiogenesis after ischemic stroke. METHODS: This study was divided into two parts. The first part of the experiment:SD rats were randomly divided into sham operation group, model group and electroacupuncture group. There were 20 rats in each group. The middle cerebral artery occlusion (MCAO) rat model was prepared using a modified Longa's method. In the electroacupuncture group, "Shuigou" (GV26) was selected for electroacupuncture intervention (4 Hz/20 Hz) for 30 min each time. The rats in the electroacupuncture group were given electroacupuncture immediately after successful modeling, once a day for 4 times. Hunter score and TTC staining were used to observe the neurological deficits and infarct volumes respectively;HE staining was used to observe the cortical pathological changes;immunohistochemistry was used to determine the changes of cerebral microvascular density. Real-time quantitative PCR and Western blot were used to observe the miR-142-5p expression, mRNA and protein expression levels of ADAMTS1, VEGF, PI3K, AKT, eNOS in ischemic cortex. The second part of the experiment:The rats were randomly divided into electroacupuncture+control group and electroacupuncture+miR-142-5p Antagomir group with 8 rats in each group. MCAO model was established after injection. Electroacupuncture+control group was given 0.9% sodium chloride solution injected into the right ventricle.The rats in the electroacupuncture+miR-142-5p Antagomir group were injected with miR-142-5p inhibitor into the right ventricle 30 min before modeling. Rats in electroacupuncture+control group and electroacupuncture+miR-142-5p Antagomir group were all given the same electroacupuncture treatment. Real-time fluorescence quantitative PCR was used to observe the effect of miR-142-5p Antagomir on the expression of miR-142-5p and ADAMTS1 mRNA. The effect of miR-142-5p Antagomir on ADAMTS1 protein was observed by Western blot. RESULTS: In the first part of the experiment, compared with the sham operation group, the Hunter score in the model group was significantly increased (P<0.01);the volume of cerebral infarction in the model group was significantly increased (P<0.01);the degree of brain edema and neuronal necrosis and the density of cerebral microvessels was increased;the cerebral microvascular density was significantly increased (P<0.01);the expression levels of miR-142-5p and the mRNA expression levels of VEGF, AKT and eNOS were significantly decreased (P<0.01, P<0.05), and the protein expression levels of VEGF, p-AKT and eNOS were significantly down-regulated (P<0.01), while the mRNA expression levels of ADAMTS1 and PI3K, and the protein expression levels of ADAMTS1 and p-PI3K were all up-regulated (P<0.01, P<0.05) in the model group. Compared with the model group, after intervention, the Hunter score in the electroacupuncture group was decreased (P<0.01), the volume of cerebral infarction was significantly decreased (P<0.01);the degree of brain edema and neuronal necrosis were alleviated;the cerebral microvascular density was significantly increased (P<0.01);the expression of miR-142-5p and the mRNA expression of VEGF, PI3K, AKT and eNOS were increased (P<0.01), the protein expressions of VEGF, p-PI3K, p-AKT and eNOS were increased (P<0.01, P<0.05), while the mRNA and protein expression of ADAMTS1 were decreased (P<0.05, P<0.01). After injection of miR-142-5p inhibitor, compared with electroacupuncture+control group, the expression of miR-142-5p in electroacupuncture+miR-142-5p Antagomir group was decreased(P<0.05), while the mRNA and protein expression of ADAMTS1 were increased (P<0.01, P<0.05). CONCLUSIONS: Electroacupuncture at GV26 can improve the neurological damage of ischemic stroke rats, reduce the volume of cerebral infarction and promote angiogenesis. The mechanism may be associated with the function of electroacupuncture in promoting the expression of miR-142-5p, so as to inhibit the expression of its target gene ADAMTS1, mediate the up-regulation of VEGF expression, activate PI3K/AKT pathway, promote the release of eNOS, and participate in promoting angiogenesis in ischemic stroke rats.

ABSTRACT

BACKGROUND: Post-stroke depression (PSD) is a prevalent complication of stroke that adversely affects patient outcomes. The etiology of PSD is complex, and no universally effective treatment exists. Acupuncture, with its historical use, combined with music therapy, presents a novel approach for PSD treatment. This study aims to systematically evaluate the clinical efficacy of combining acupuncture with music therapy for PSD through a meta-analysis. METHODS: We systematically searched both Chinese and English literature in PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and the Chinese Science and Technology Periodical Database (VIP Database) for randomized controlled trials evaluating acupuncture combined with music therapy for PSD. Two independent evaluators conducted quality assessments and data extraction. Statistical analyses were performed using RevMan 5.4 and Stata 18.0 software. RESULTS: This article contains 11 studies, involving a total of 698 patients. The results of the meta-analysis showed that, compared with the control group, the test group showed significant improvement on multiple outcome measures: HAMD score [mean difference (MD) = -3.18, 95% confidence interval (CI) (-3.61, -2.76), P < .00001], Self-Rating Depression Scale score [MD = -5.12, 95% CI (-6.61, -3.63), P < .00001], Pittsburgh sleep quality index score [MD = -2.40, 95% CI (-2.96, -1.84), P < .00001], BI score [MD = 14.16, 95% CI (4.37, 23.94), P = .005] were all significantly lower, significantly higher effectiveness [risk ratio = 1.21, 95% CI (1.11, 1.33), P < .0001]. These differences were also statistically significant. CONCLUSION: The use of acupuncture combined with music therapy is effective in reducing depression in PSD patients.

ABSTRACT

INTRODUCTION: Several systematic reviews and meta-analyses (SRs/MAs) of clinical trials showed the efficacy of acupuncture for post-stroke motor impairment. To systematically estimate and synthesise these results, we aimed to conduct an overview of SRs/MAs to summarise the evidence and evaluate the methodological quality regarding the effectiveness and safety of acupuncture for post-stroke motor impairment. METHODS AND ANALYSIS: This is a protocol for an overview of SRs/MAs. A literature search will be conducted in PubMed, Embase, Web of Science and Cochrane Central Registry of Controlled Trials from the construction of the database to March 2024. SRs/MAs evaluating the efficacy of acupuncture in post-stroke motor impairment patients will be included. Two independent investigators will screen and evaluate related SRs/MAs back-to-back. We will extract data into a predefined form designed to summarise the key characteristics of each study. The evaluation of methodological quality of the included SRs/MAs will be assessed using AMSTAR-2, the PRISMA 2020 checklist and the GRADE grading system. ETHICS AND DISSEMINATION: Ethics approval is not required for this overview as we will only analyse published literature. The results will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42024502006.

ABSTRACT

INTRODUCTION: Stroke is a common cause of death and disability in the older adult and increases the risk and severity of cognitive impairment, which is a factor for long-term death among stroke survivors. Some studies have focused on the effects of reminiscence therapy with different media on stroke survivors. It is currently unclear which is the best medium. This protocol aims to deal with this problem by using a network meta-analysis. METHODS AND ANALYSIS: Published randomised controlled trials will be included if reminiscence therapy plus usual care was applied in older adult patients who had a stroke in the experimental group and usual care was applied in the control group. Six electronic databases will be searched from their inception to August 2023, including the Cochrane Library, CINAHL, PubMed, Web of Science, Medline and Embase. The media of reminiscence therapy may include (but not restricted to) old photos, music or movies. Outcomes will be cognitive function and negative moods. Study selection, data extraction and quality assessment will be performed independently by two reviewers. The risk of bias (RoB) of the included studies will be evaluated in accordance with the Cochrane Collaboration's RoB tool. The evidence quality will be measured based on the Grading of Recommendations Assessment, Development and Evaluation. To compare the efficacy of reminiscence therapy with different media, standard pairwise meta-analysis and Bayesian network meta-analysis will be conducted. The probabilities of intervention for all outcomes will be ranked based on the surface under the cumulative ranking curve. ETHICS AND DISSEMINATION: Ethical approval is not required for reviewing published studies. The findings will be submitted to a peer-reviewed journal for review and publication to provide important evidence for clinicians and guideline developers to determine interventions for older adult patients who had a stroke.

ABSTRACT

BACKGROUND: Currently, there are no agreed quality standards for post-stroke aphasia services. Therefore, it is unknown if care reflects best practices or meets the expectations of people living with aphasia. We aimed to (1) shortlist, (2) operationalise and (3) prioritise best practice recommendations for post-stroke aphasia care. METHODS: Three phases of research were conducted. In Phase 1, recommendations with strong evidence and/or known to be important to people with lived experience of aphasia were identified. People with lived experience and health professionals rated the importance of each recommendation through a two-round e-Delphi exercise. Recommendations were then ranked for importance and feasibility and analysed using a graph theory-based voting system. In Phase 2, shortlisted recommendations from Phase 1 were converted into quality indicators for appraisal and voting in consensus meetings. In Phase 3, priorities for implementation were established by people with lived experience and health professionals following discussion and anonymous voting. FINDINGS: In Phase 1, 23 best practice recommendations were identified and rated by people with lived experience (n = 26) and health professionals (n = 81). Ten recommendations were shortlisted. In Phase 2, people with lived experience (n = 4) and health professionals (n = 17) reached a consensus on 11 quality indicators, relating to assessment (n = 2), information provision (n = 3), communication partner training (n = 3), goal setting (n = 1), person and family-centred care (n = 1) and provision of treatment (n = 1). In Phase 3, people with lived experience (n = 5) and health professionals (n = 7) identified three implementation priorities: assessment of aphasia, provision of aphasia-friendly information and provision of therapy. INTERPRETATION: Our 11 quality indicators and 3 implementation priorities are the first step to enabling systematic, efficient and person-centred measurement and quality improvement in post-stroke aphasia services. Quality indicators will be embedded in routine data collection systems, and strategies will be developed to address implementation priorities. PATIENT AND PUBLIC CONTRIBUTION: Protocol development was informed by our previous research, which explored the perspectives of 23 people living with aphasia about best practice aphasia services. Individuals with lived experience of aphasia participated as expert panel members in our three consensus meetings. We received support from consumer advisory networks associated with the Centre for Research Excellence in Aphasia Rehabilitation and Recovery and the Queensland Aphasia Research Centre.

ABSTRACT

In the 2024 David G. Sherman Lecture, Steven J. Warach, illustrating with examples from his research, walks through the history of magnetic resonance imaging in acute stroke from the 1990s and early 2000s with the introduction, validation, and application of diffusion-weighted imaging, penumbral imaging (the diffusion-perfusion mismatch), and other imaging markers of the acute stroke pathology into routine clinical practice and stroke trials. The adaptation of diffusion-weighted imaging for clinical scanners in the acute hospital setting began a revolution in ischemic stroke diagnosis as the presence, location, and size of ischemic lesions could now be visualized at the earliest times after stroke onset when computed tomography and conventional magnetic resonance imaging still appeared normal. In combination with perfusion magnetic resonance imaging, diffusion-weighted imaging made imaging of the ischemic penumbra a practical reality for routine clinical use and feasible for integration as a selection tool into clinical trials. It was apparent from the initial use of diffusion-perfusion imaging in acute stroke that many patients had persistence of penumbra as late as 24 hours after stroke onset although the probability of penumbra decreased over time. The therapeutic time window for ischemic stroke selected by clinical and temporal criteria reflected the decreased proportion of patients with the therapeutic target over time rather than the absence of the penumbral target in all patients at later times. This work provided the empirical and conceptual framework for the shift toward selection and evaluation of patients for acute stroke therapies based on direct observation of the target pathology and away from the exclusive dependence on clinical and temporal surrogates to infer the presence of stroke therapeutic targets, a shift that has expanded the indications for acute reperfusion therapies over the last 10 years.

ABSTRACT

BACKGROUND: The discrepancy between experimental research and clinical trial outcomes is a persistent challenge in preclinical studies, particularly in stroke research. A possible factor contributing to this issue is the lack of standardization across experimental stroke models, leading to poor reproducibility in multicenter studies. This study addresses this gap by aiming to enhance reproducibility and the efficacy of multicenter studies through the harmonization of protocols and training of involved personnel. METHODS: We established a set of standard operating procedures for various stroke models and the Neuroscore. These standard operating procedures were implemented across multiple research centers, followed by specialized, in-person training for all participants. We measured the variability in infarct volume both before and after the implementation of these standardized protocols and training sessions. RESULTS: The standardization process led to a significant reduction in variability of infarct volume across different stroke models (40%-50% reduction), demonstrating the effectiveness of our harmonized protocols and training. Additionally, the implementation of the Neuroscore system across centers showed low variability and consistent results up to 28 days poststroke, underscoring its utility in chronic phase evaluations. CONCLUSIONS: The harmonization of protocols and surgeon training significantly reduced variability in experimental outcomes across different centers. This improvement can increase the comparability of data between research groups and enhance the statistical power of multicenter studies. Our findings also establish the Neuroscore as a reliable tool for long-term assessment in stroke research, paving the way for more consistent and impactful multicenter preclinical studies.

ABSTRACT

INTRODUCTION: Hospital overcrowding where patient admissions exceed capacity is associated with worse outcomes in Emergency Department. Developments in emergency stroke care have been associated with improvements in stroke outcome but are dependent on effective, organised care. We examined if overcrowding in the hospital system was associated with negative changes in stroke outcome. METHODS: Data on overcrowding were obtained from the Irish Nurses and Midwives Organisation (INMO) 'Trolley Count' database recording the number of patients cared for on trolleys/chairs in all acute hospitals each midnight. These were compared with quarterly data from the Irish National Audit of Stroke from 2013 to 2021 inclusive. Variables analysed were inpatient mortality rate, thrombolysis rate for ischaemic stroke, median door to needle time and median length of stay. RESULTS: 579449 patient episodes were recorded by Trolley Watch over the period, (Quarterly Median 16719.5, range 3389-27015). Average Quarterly Thrombolysis rate was 11.3% (sd 1.3%) Median Quarterly Inpatient Mortality rate was 11.8% (Range 8.9-14.0%). Median Quarterly Length of stay was 9 days (8-11 days). Median quarterly door to needle was 65 min (45-80 min). Q1 was typically the worst for overcrowding with on average 19777 incidences (sd 4786). This was significantly higher than for Q2 (mean 13540 (sd 4785) p = 0.005 t-test) and for Q3 (mean 14542 (sd 4753) p = 0.03). No significant correlation was found between quarterly Trolley watch episodes and inpatient mortality (r = 0.084, p = 0.63), median length of stay r=-0.15, p = 0.37) or thrombolysis rate (r = 0.089 p = 0.61). There was an unexpected significant negative correlation between trolley watch data and median door to needle time (r=-0.36, p = 0.03). CONCLUSION: Despite increasing hospital overcrowding, stroke services still managed to preserve standard of care. We could find no association between levels of overcrowding and deterioration in selected indices of patient care.

ABSTRACT

The research team assessed community acceptability of prehospital stroke telemedicine services in rural O'ahu communities. Tools were developed to evaluate patient-centered goals about implementing ambulance-based telemedicine which aimed to retain appropriate patients in community hospitals and improve thrombolytic treatment times. Using a mixed methods approach, the team surveyed well-appearing adults (ie, able to complete survey and interview) at O'ahu community events. Participants were asked to complete a short Likert-scale questionnaire (n=263) followed by a semi-structured interview (n=29). Data were summarized by descriptive and inferential statistics. Comparisons between rural and urban groups were made by chi-square analysis and Wilcoxon rank-sum 2-tailed test. Interviews were transcribed, coded, and analyzed using inductive and deductive methods. The findings suggest that use of prehospital telemedicine for specialty care is viewed favorably by both rural and urban respondents. Additionally, most respondents felt comfortable staying at their local hospital if they had access to a specialist by telemedicine. However, mistrust in rural hospitals may be a potential barrier to implementation. Compared to urban respondents, rural respondents were less confident in their local hospital's resources and capabilities for stroke care. The findings identified a potential misalignment of the project's goal with some patients' goal to use emergency medical services (EMS) to bypass rural hospitals for stroke care. Future community outreach efforts are needed to encourage activation of EMS and highlight the advantages of utilizing prehospital telemedicine for accessing specialty care thereby improving treatment times.

ABSTRACT

BACKGROUND: People with stroke and their families face numerous challenges as they leave hospital to return home, often experiencing multifaceted unmet needs and feelings of abandonment. The essential elements of an intervention intended to support transition-to-home after stroke are unclear. OBJECTIVE: The aim of the project was to engage in a co-design process to identify the key components of a pragmatic intervention to inform a transition-to-home support pathway following stroke. MATERIALS AND METHODS: The study was conducted using a co-design process engaging multiple stakeholders, including 12 people with stroke, 6 caregivers, 26 healthcare professionals and 6 individuals from stroke organisations in a series of three workshops, facilitated by the primary researcher, a wider team of researchers and an individual with lived experience of stroke. World Café methodology and Liberating Structures facilitation techniques were adapted to meet the aim of the workshops. Data collection involved observations during workshops, followed by summarising of findings and reaching group consensus agreement on outputs. Facilitated consensus on a prioritisation task resulted in the final output. RESULTS: The co-design group identified 10 key intervention components of a transition-to-home support pathway following stroke. These components focussed on enhancing collaboration, streamlining transition processes and facilitating post-discharge support. While a stroke coordinator was considered a top priority, increased cross-setting information sharing and community in-reach, where community-based healthcare staff extended their services into hospital settings to provide continuity care, were considered most feasible to implement. CONCLUSION: The co-design approach, involving a multi-stakeholder group and strengthened by patient and public involvement, ensured that the identified transition-to-home intervention components are meaningful and relevant for people with stroke and their families. Further co-design workshops are required to refine, and feasibility test the components for generalisability within the wider Irish healthcare setting. PATIENT OR PUBLIC CONTRIBUTION: Individuals who have experienced a stroke actively contributed to shaping the methodological design of this study and the ethics process. They engaged in the analysis of co-design outputs and provided input for the discussion and recommendations regarding future research. An individual who had experienced a stroke formed part of the research team, co-facilitating the co-design workshops and co-authoring this article.
