A Scoping Review of Patient and Public Involvement (PPI) in Empirical Stroke Research.

BACKGROUND: Impactful, evidence-based solutions in surveillance, prevention, acute care, and rehabilitation for stroke survivors are required to address the high global burden of stroke. Patient and Public Involvement (PPI), where patients, their families, and the public are actively involved as research partners, enhances the relevance, credibility, and impact of stroke-related research. AIMS: This scoping review, adhering to the PRISMA Scoping Review guidelines, aims to identify and summarize how PPI is currently implemented and reported in empirical stroke research using a participatory approach. SUMMARY OF REVIEW: A comprehensive search strategy was developed and implemented across Medline, CINAHL, EMBASE, PsynchINFO and Cochrane electronic databases, supplemented by grey literature searches. Empirical stroke research papers in the English language, published from 2014 up to 2023 and documenting PPI activity were included. Of the 18,143 original papers identified, 2,824 full text manuscripts matching from this time window were screened. Only 2% (n=72) of these directly reported embedded PPI activity in empirical research. The majority were qualitative in design (60%) and were conducted in high-income countries (96%). Only one included study originated from a developing country, where the burden of stroke is highest. Most studies (94%) provided some information about the activities carried out with their PPI partners, mainly centered on the study design (57%) and management (64%), with only 4% of studies integrating PPI across all research cycle phases from funding application through to dissemination. When studies were examined for compliance with the Guidance for Reporting Involvement of Patients and the Public (GRIPP2) short form checklist, only 11% of included studies were 100% compliant. Twenty-one studies (29%) reported barriers and facilitators to including PPI in stroke research. Organization, authentic partnership and experienced PPI representatives were common facilitators and identified barriers reflected concerns around adequate funding, time required and diversity in perspectives. A positive reporting bias for PPI impact was observed, summarized as keeping the patient perspective central to the research process, improved care of study participants, validation of study findings, and improved communication / lay-summaries of complex research concepts. CONCLUSIONS: PPI is underutilised and inconsistently reported in current empirical stroke research. PPI must become more widely adopted, and notably in low- and middle-income countries. Consensus-driven standards for inclusion of PPI by funding organisations and publishers is required to support its widespread adoption.

Effectiveness of behavior change and self-management theoretically-informed telehealth interventions for stroke secondary prevention: An overview of systematic reviews.

INTRODUCTION: Despite the increased use of telehealth interventions, low-level evidence supports their use for behavior change and self-management in stroke secondary prevention. Therefore, this overview of systematic reviews (SRs) critically appraises and consolidates the evidence about theoretically-informed telehealth interventions in stroke secondary prevention. METHODS: Two phases were conducted independently by two reviewers. Phase-1 included SRs contemplating randomized controlled trials (RCTs) implementing telehealth interventions with individuals post-stroke, targeting cardiovascular events, risk-reducing health behaviors or physiological risk factors. Phase-2 interrogated RCTs from these SRs that implemented theoretically-informed interventions. Best-evidence synthesis of published meta-analyses and new meta-analyses of theoretically-informed interventions were conducted. GRADE evidence was applied. RESULTS: In Phase-1 (15 SRs), best-evidence synthesis identified telehealth interventions as effective in reducing recurrent angina and recurrent stroke rates (both with very low GRADE), improving medication adherence (low GRADE), physical activity participation (very low GRADE), and blood pressure targets (very low GRADE), reducing systolic blood pressure (SBP) (moderate GRADE) and low-density lipoprotein levels (very low GRADE). In Phase-2 (14 RCTs), new meta-analyses identified theoretically-informed telehealth interventions as effective in improving medication adherence (SMD: 0.38; 95%CI: 0.13-0.64; I²: 72%, low GRADE) and healthy eating (SMD: 0.38; 95%CI: 0.15-0.60; I²: 38%, low GRADE), and decreasing SBP (MD: -9.19; 95%CI: -5.49 to -12.89; I²: 0%, moderate GRADE). DISCUSSION: Telehealth demonstrates utility in stroke secondary prevention, notably in SBP reduction. High-quality RCTs are required given the lack of current evidence supporting theoretically-informed telehealth interventions addressing primary outcomes of secondary prevention, and the low certainty evidence identified for health behavior change.

Reducing risk behaviours after stroke: An overview of reviews interrogating primary study data using the Theoretical Domains Framework.

BACKGROUND: Lifestyle changes, in addition to preventive medications, optimise stroke secondary prevention. Evidence from systematic reviews support behaviour-change interventions post-stroke to address lifestyle-related risk. However, understanding of the theory-driven mediators that affect behaviour-change post-stroke is lacking. METHODS: Electronic databases MEDLINE, Embase, Epistemonikos and Cochrane Library of Systematic Reviews were searched to March 2023 for systematic reviews addressing behaviour-change after stroke. Primary studies from identified systematic reviews were interrogated for evidence supporting theoretically-grounded interventions. Data were synthesized in new meta-analyses examining behaviour-change domains of the Theoretical Domains Framework (TDF) and secondary prevention outcomes. RESULTS: From 71 identified SRs, 246 primary studies were screened. Only 19 trials (N = 2530 participants) were identified that employed theoretically-grounded interventions and measured associated mediators for behaviour-change. Identified mediators mapped to 5 of 14 possible TDF domains. Trial follow-up ranged between 1-12 months and no studies addressed primary outcomes of recurrent stroke or cardiovascular mortality and/or morbidity. Lifestyle interventions targeting mediators mapped to the TDF Knowledge domain may improve the likelihood of medication adherence (OR 6.08 [2.79, 13.26], I2 = 0%); physical activity participation (OR 2.97 [1.73, 5.12], I2 = 0%) and smoking cessation (OR 10.37 [3.22, 33.39], I2 = 20%) post-stroke, supported by low certainty evidence; Lifestyle interventions targeting mediators mapping to both TDF domains of Knowledge and Beliefs about Consequences may improve medication adherence post-stroke (SMD 0.36 [0.07, 0.64], I2 = 13%, very low certainty evidence); Lifestyle interventions targeting mediators mapped to Beliefs about Capabilities and Emotions domains may modulate low mood post-stroke (SMD -0.70 [-1.28, -0.12], I2 = 81%, low certainty evidence). CONCLUSION: Limited theory-based research and use of behaviour-change mediators exists within stroke secondary prevention trials. Knowledge, Beliefs about Consequences, and Emotions are the domains which positively influence risk-reducing behaviours post-stroke. Behaviour-change interventions should include these evidence-based constructs known to be effective. Future trials should address cardiovascular outcomes and ensure adequate follow-up time.

Responsiveness of respiratory function in Parkinson's Disease to an integrative exercise programme: A prospective cohort study.

INTRODUCTION: Respiratory disorders are the most common cause of death in Parkinson's Disease (PD). Conflicting data exist on the aetiology of respiratory dysfunction in PD and few studies examine the effects of exercise-based interventions on respiratory measures. This study was conducted to better understand respiratory dysfunction in PD and to identify measures of dysfunction responsive to an integrative exercise programme. OBJECTIVES: The objectives were to compare baseline respiratory measures with matched, published population norms and to examine immediate and longer-term effects of a 12-week integrated exercise programme on these measures. DESIGN: Twenty-three people with mild PD (median Hoehn & Yahr = 2) self-selected to participate in this exploratory prospective cohort study. Evaluation of participants occurred at three time points: at baseline; following the 12-week exercise programme and at 4-month follow-up. OUTCOME MEASURES: Outcome measures included: Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), FEV1/FVC ratio, Peak Expiratory Flow (PEF), Inspiratory Muscle Strength (MIP), Expiratory Muscle Strength (MEP), Peak Cough Flow (PCF), and Cardiovascular Fitness measures of estimated VO2 max and 6-Minute Walk Test (6MWT). RESULTS: Compared to published norms, participants had impaired cough, reduced respiratory muscle strength, FEV, FVC, PEF and cardiovascular fitness. Post exercise intervention, statistically significant improvements were noted in MEP, cardiovascular fitness, and PEF. However only gains in PEF were maintained at 4-month follow-up. CONCLUSIONS: Significant respiratory dysfunction exists, even in the early stages of PD. Metrics of respiratory muscle strength, peak expiratory flow and cardiovascular fitness appear responsive to an integrative exercise programme.

Interventions for Behaviour Change and Self-Management of Risk in Stroke Secondary Prevention: An Overview of Reviews.

INTRODUCTION: Optimised secondary prevention strategies that include lifestyle change are recommended after stroke. While multiple systematic reviews (SRs) address behaviour change interventions, intervention definitions, and associated outcomes differ between reviews. This overview of reviews addresses the pressing need to synthesise high-level evidence for lifestyle-based behavioural and/or self-management interventions to reduce risk in stroke secondary prevention in a structured, consistent way. METHODS: Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria were applied to meta-analyses, demonstrating statistically significant effect sizes to establish the certainty of existing evidence. Electronic databases MEDLINE, Embase, Epistemonikos, and the Cochrane Library of Systematic Reviews were systematically searched, current to March 2023. RESULTS: Fifteen SRs were identified following screening, with moderate overlap of primary studies demonstrated (5.84% degree of corrected covered area). Interventions identified could be broadly categorised as multimodal; behavioural change; self-management; psychological talk therapies, albeit with overlap between some theoretical domains. Seventy-two meta-analyses addressing twenty-one preventive outcomes of interest were reported. Best-evidence synthesis identifies that for primary outcomes of mortality and future cardiovascular events post-stroke, moderate certainty GRADE evidence supports multimodal interventions to reduce cardiac events, with no available evidence for outcomes of mortality (all-cause or cardiovascular) or recurrent stroke events. For secondary outcomes addressing risk-reducing behaviours, best-evidence synthesis identifies moderate certainty GRADE evidence for multimodal lifestyle-based interventions to increase physical activity participation, and low certainty GRADE evidence for behavioural change interventions to improve healthy eating post-stroke. Similarly, low certainty GRADE evidence supports self-management interventions to improve preventive medication adherence. For mood self-management post-stroke, moderate GRADE evidence supports psychological therapies for remission and/or reduction of depression and low/very low certainty GRADE evidence for reduction of psychological distress and anxiety. Best-evidence for outcomes addressing proxy physiological measures identified low GRADE evidence supporting multimodal interventions to improve blood pressure, waist circumference, and LDL cholesterol. CONCLUSION: Effective strategies to redress risk-related health behaviours are required in stroke survivors to complement current pharmacological secondary prevention. Inclusion of multimodal interventions and psychological talk therapies in evidence-based stroke secondary prevention programmes is warranted given the moderate GRADE of evidence that supports their role in risk reduction. Given the overlap in primary studies across reviews, often with overlapping theoretical domains between broad intervention categories, further research is required to identify optimal intervention behavioural change theories and techniques employed in behavioural/self-management interventions.

Prediction of Gait Kinematics and Kinetics: A Systematic Review of EMG and EEG Signal Use and Their Contribution to Prediction Accuracy.

Human-machine interfaces hold promise in enhancing rehabilitation by predicting and responding to subjects' movement intent. In gait rehabilitation, neural network architectures utilize lower-limb muscle and brain activity to predict continuous kinematics and kinetics during stepping and walking. This systematic review, spanning five databases, assessed 16 papers meeting inclusion criteria. Studies predicted lower-limb kinematics and kinetics using electroencephalograms (EEGs), electromyograms (EMGs), or a combination with kinematic data and anthropological parameters. Long short-term memory (LSTM) and convolutional neural network (CNN) tools demonstrated highest accuracies. EEG focused on joint angles, while EMG predicted moments and torque joints. Useful EEG electrode locations included C3, C4, Cz, P3, F4, and F8. Vastus Lateralis, Rectus Femoris, and Gastrocnemius were the most commonly accessed muscles for kinematic and kinetic prediction using EMGs. No studies combining EEGs and EMGs to predict lower-limb kinematics and kinetics during stepping or walking were found, suggesting a potential avenue for future development in this technology.

Effect of Lower Limb Exoskeleton on the Modulation of Neural Activity and Gait Classification.

Neurorehabilitation with robotic devices requires a paradigm shift to enhance human-robot interaction. The coupling of robot assisted gait training (RAGT) with a brain-machine interface (BMI) represents an important step in this direction but requires better elucidation of the effect of RAGT on the user's neural modulation. Here, we investigated how different exoskeleton walking modes modify brain and muscular activity during exoskeleton assisted gait. We recorded electroencephalographic (EEG) and electromyographic (EMG) activity from ten healthy volunteers walking with an exoskeleton with three modes of user assistance (i.e., transparent, adaptive and full assistance) and during free overground gait. Results identified that exoskeleton walking (irrespective of the exoskeleton mode) induces a stronger modulation of central mid-line mu (8-13 Hz) and low-beta (14-20 Hz) rhythms compared to free overground walking. These modifications are accompanied by a significant re-organization of the EMG patterns in exoskeleton walking. On the other hand, we observed no significant differences in neural activity during exoskeleton walking with the different assistance levels. We subsequently implemented four gait classifiers based on deep neural networks trained on the EEG data during the different walking conditions. Our hypothesis was that exoskeleton modes could impact the creation of a BMI-driven RAGT. We demonstrated that all classifiers achieved an average accuracy of 84.13±3.49% in classifying swing and stance phases on their respective datasets. In addition, we demonstrated that the classifier trained on the transparent mode exoskeleton data can classify gait phases during adaptive and full modes with an accuracy of 78.3±4.8% , while the classifier trained on free overground walking data fails to classify the gait during exoskeleton walking (accuracy of 59.4±11.8% ). These findings provide important insights into the effect of robotic training on neural activity and contribute to the advancement of BMI technology for improving robotic gait rehabilitation therapy.

Exoskeleton Training Modulates Complexity in Movement Patterns and Cortical Activity in Able-Bodied Volunteers.

Robot-aided gait training (RAGT) plays a crucial role in providing high-dose and high-intensity task-oriented physical therapy. The human-robot interaction during RAGT remains technically challenging. To achieve this aim, it is necessary to quantify how RAGT impacts brain activity and motor learning. This work quantifies the neuromuscular effect induced by a single RAGT session in healthy middle-aged individuals. Electromyographic (EMG) and motion (IMU) data were recorded and processed during walking trials before and after RAGT. Electroencephalographic (EEG) data were recorded during rest before and after the entire walking session. Linear and nonlinear analyses detected changes in the walking pattern, paralleled by a modulation of cortical activity in the motor, attentive, and visual cortices immediately after RAGT. Increases in alpha and beta EEG spectral power and pattern regularity of the EEG match the increased regularity of body oscillations in the frontal plane, and the loss of alternating muscle activation during the gait cycle, when walking after a RAGT session. These preliminary results improve the understanding of human-machine interaction mechanisms and motor learning and may contribute to more efficient exoskeleton development for assisted walking.

A systematic review and meta-analysis of respiratory dysfunction in Parkinson's disease.

INTRODUCTION: Respiratory dysfunction in Parkinson's disease (PD) is common and associated with increased hospital admission and mortality rates. Central and peripheral mechanisms have been proposed in PD. To date no systematic review identifies the extent and type of respiratory impairments in PD compared with healthy controls. METHODS: PubMed, EMBASE, CINAHL, Web of Science, Pedro, MEDLINE, Cochrane Library and OpenGrey were searched from inception to December 2021 to identify case-control studies reporting respiratory measures in PD and matched controls. RESULTS: Thirty-nine studies met inclusion criteria, the majority with low risk of bias across Risk of Bias Assessment tool for Non-randomized Studies (RoBANS) domains. Data permitted pooled analysis for 26 distinct respiratory measures. High-to-moderate certainty evidence of impairment in PD was identified for vital capacity (standardised mean difference [SMD] 0.75; 95% CI 0.45-1.05; p < 0.00001; I2  = 10%), total chest wall volume (SMD 0.38; 95% CI 0.09-0.68; p = 0.01; I2  = 0%), maximum inspiratory pressure (SMD 0.91; 95% CI 0.64-1.19; p < 0.00001; I2  = 43%) and sniff nasal inspiratory pressure (SMD 0.58; 95% CI 0.30-0.87; p < 0.00001; I2  = 0%). Sensitivity analysis provided high-moderate certainty evidence of impairment for forced vital capacity and forced expiratory volume in 1 s during medication ON phases and increased respiratory rate during OFF phases. Lower certainty evidence identified impairments in PD for maximum expiratory pressure, tidal volume, maximum voluntary ventilation and peak cough flow. CONCLUSIONS: Strong evidence supports a restrictive pattern with inspiratory muscle weakness in PD compared with healthy controls. Limited data for central impairment were identified with inconclusive findings.

Stroke Secondary Prevention: Everyone's Business.

A protocol to evaluate the impact of embedding Public and Patient Involvement in a structured PhD program for stroke care.

Background: Embedding Public and Patient Involvement (PPI) in postgraduate research has been recognized as an important component of post-graduate training, providing research scholars with an awareness and a skillset in an area which prepares them for future roles as healthcare researchers. Improving Pathways for Acute STroke And Rehabilitation (iPASTAR) is a structured PhD training program [Collaborative Doctoral Award (CDA)] which aims to design a person-centered stroke pathway throughout the trajectory of stroke care, to optimize post-stroke health and wellbeing. PPI is embedded at all stages. Purpose: The iPASTAR research programme was strongly informed by a round-table PPI consultation process with individuals who experienced stroke and who provided broad representation across ages, gender, geographical locations (urban and rural) and the PhD themed areas of acute care, early supported discharge and lifestyle-based interventions after stroke. Four PhD scholars taking part in the CDA-iPASTAR now work collaboratively with four stroke champions, supported by a wider PPI advisory panel. Methods: This study will evaluate the process and impact of embedding PPI during a PhD program. We will conduct a longitudinal mixed-methods evaluation, conducting focus groups at 24, 36, and 48 months to explore the experiences of the key stakeholders involved. The participants will include PhD scholars, PPI partners (PPI Advisory Group and PPI Champions), PhD supervisors and a PPI manager. An independent researcher will conduct the evaluation. We will include focus groups, individual interviews and participant reflections. Qualitative data will be analyzed using thematic and content analysis, quantitative data will be analyzed using descriptive statistics. Discussion: PPI and patient voice initiatives bring together researchers, family, and people with health care issues into meaningful dialogue and allow the development of a patient-voice learning network. Embedding PPI training within a PhD program can build meaningful capacity in PPI partnerships in stroke research.

Stroke survivor perceptions of using an exoskeleton during acute gait rehabilitation.

Robotic-assisted gait training (RAGT) devices allow intensive high repetition of the gait cycle in individuals with locomotor disability, with reduced therapist effort. In addition to usual rehabilitation, RAGT post-stroke improves the likelihood of regaining independent walking, with maximum efficacy identified in the acute and subacute phases of stroke. This study explores the usability and acceptance of RAGT among persons with stroke in an acute hospital setting and examines users' perceptions of two different modes of robotic assistance provided during rehabilitation. A mixed-methods approach comprised semi-structed interviews of end-user perspectives of RAGT in an acute hospital setting following stroke and two 10-point Likert scales rating how comfortable and how natural robotic gait felt using different assistance modes. Content analysis of qualitative data was undertaken with results synthesised by common meaning units. Quantitative data were reported using summary statistics, with Spearmann's correlation co-efficient examining the relationship between Likert scale ratings and measures of participants' stroke related disability. Ten individuals (6 men; 4 women; mean age of 64.5. ± 13 years) were recruited in an acute hospital setting following admission with a stroke diagnosis. Content analysis of interview transcripts identified discussion units centring around positive aspects of how helpful the device was, negative aspects related to set-up time, weight of the device and multiple instructions delivered during use. Initially participants identified that the device could look intimidating, and they feared falling in the device but they subsequently identified the correct mindset for using the device is to trust the technology and not be afraid. Mean ratings for device comfort (7.94 ± 1.4) and how natural walking felt (7.05 ± 1.9) were favourable. Interestingly, a strong relationship was identified, whereby the higher the level of disability, the more natural participants rated walking in the device during maximal assistance mode (rho = 0.62; p = 0.138). This study suggests individuals in the early phases of stroke perceive RAGT to be acceptable and helpful in the main, with some associated negative aspects. Walking in the device was rated as comfortable and natural. Those with greater disability rated the assisted walking as more natural.

Perspectives and Experiences of Cardiac Rehabilitation after Stroke-A Qualitative Study.

Cardiac rehabilitation (CR) after stroke has been proven to be a safe and feasible secondary prevention intervention. Limited qualitative data capture people's experiences and perceptions of attending CR following stroke, but with none addressing translational aspects when CR is delivered as routine clinical care. Using a phenomenological, qualitative approach, four semi-structured focus groups were conducted with 15 individuals (60% male) who had completed CR during their stroke care pathway. Our inductive thematic analysis identified five themes. The first centred on recognising stroke as a cardiovascular disease and the applicability of CR post-stroke. The second addressed how peer understanding, camaraderie, and medical supervision created a safe and supportive environment. The third identified how the programme-built confidence supported longer-term healthy lifestyle choices in physical activity, diet, and smoking. The penultimate theme addressed the period from hospital discharge to attending CR as a time of uncertainty where many participants experienced cognitive difficulties, mood disturbances, and mental fatigue without adequate support. Lastly, participants identified unmet needs in their care pathway that included a lack of information about their referral to CR, the programme content, and accessing local supports ahead of CR. Ongoing and unmet needs both during and after CR related to self-management of secondary prevention medications, neurological issues, post-stroke fatigue, and the lack of structured support following CR completion.

A Scoping Review of Non-Pharmacological, Non-Surgical Secondary Prevention Strategies in Ischaemic Stroke and TIA in National Stroke Guidelines and Clinical Audit Documents.

The Stroke Action Plan for Europe (2018-2030) calls for national-level secondary prevention plans that address lifestyle, in addition to prevention medications and surgical interventions. This scoping review examines national stroke care guideline and audit documents across WHO regions to identify non-pharmacological, non-surgical stroke secondary prevention recommendations and associated performance indicators. Using a snowballing methodology, 27 guideline documents met the inclusion criteria. Sixteen (59%) detailed, non-pharmacological, non-surgical stroke secondary prevention-addressing known, modifiable population attributable risk factors, of physical inactivity (N = 11), smoking (N = 11), unsafe alcohol consumption (N = 10), diet (N = 8), weight (N = 5), stress (N = 4) and depression (N = 2). Strategies recommended to address these risk factors were: assessment of stroke risk/risk factors (N = 4); provision of advice and information on reducing lifestyle related risk (N = 16); education and counselling for lifestyle behaviour change (N = 8) and onward referral for specialist management of risk (N = 4). Of the nine stroke audits/registries identified, only three (33%) included non-pharmacological, non-surgical quality indicators of documented provision of advice or information on the following: general lifestyle (N = 2); smoking cessation for current smokers (N = 2); reduction in alcohol consumption, where relevant (N = 1), exercise participation (N = 1) and diet (N = 1). Preventive quality indicators addressing the management of weight, stress or depression were absent. This review highlights current gaps in optimal stroke secondary prevention recommendations and their implementation.

Fit for life after cancer: does exercise timing matter?

OBJECTIVES: To assess the effects of a single exercise session per week for 6 weeks on quality of life (QoL), fatigue and exercise participation in male and female cancer survivors with follow-up at 6 months. A secondary aim was to identify if the timing of exercise delivery determined its effect. METHODS: An exploratory prospective cohort study design was implemented. Twenty-five patients undergoing or who had completed cancer treatment (11 active treatment; 14 completed treatment) undertook exercise and educational sessions (Fit for Life) 1×/week. The Brief Fatigue Inventory (BFI), the European Organisation for Research and Treatment of Cancer QoL C-30 (EORTC QLQ C-30) and the Godin Leisure Time Exercise Questionnaire (GLTEQ) were used to assess fatigue, QoL and exercise levels, respectively. Participants were evaluated before and after the intervention, and after 6 months. RESULTS: There was a significant group × time interaction for the GLTEQ at 6 months post in favour of exercising during active treatment (p=0.01). No other group × time interactions were observed across the EORTC QLQ C-30 or BFI. There was a significant main effect for time for EORTC QLQ C-30 Global with a significant increase observed between pre and 6 months post. CONCLUSIONS: Exercise 1×/week delivered during treatment may impact on long-term exercise participation in adult cancer survivors. This lower volume programme may improve QoL, but has minimal effect on fatigue suggesting an insufficient exercise dosage to impact this variable. This study generates interesting proof of concept results and may be helpful in the development of larger randomised controlled trials.

Experimental Protocol to Assess Neuromuscular Plasticity Induced by an Exoskeleton Training Session.

Exoskeleton gait rehabilitation is an emerging area of research, with potential applications in the elderly and in people with central nervous system lesions, e.g., stroke, traumatic brain/spinal cord injury. However, adaptability of such technologies to the user is still an unmet goal. Despite important technological advances, these robotic systems still lack the fine tuning necessary to adapt to the physiological modification of the user and are not yet capable of a proper human-machine interaction. Interfaces based on physiological signals, e.g., recorded by electroencephalography (EEG) and/or electromyography (EMG), could contribute to solving this technological challenge. This protocol aims to: (1) quantify neuro-muscular plasticity induced by a single training session with a robotic exoskeleton on post-stroke people and on a group of age and sex-matched controls; (2) test the feasibility of predicting lower limb motor trajectory from physiological signals for future use as control signal for the robot. An active exoskeleton that can be set in full mode (i.e., the robot fully replaces and drives the user motion), adaptive mode (i.e., assistance to the user can be tuned according to his/her needs), and free mode (i.e., the robot completely follows the user movements) will be used. Participants will undergo a preparation session, i.e., EMG sensors and EEG cap placement and inertial sensors attachment to measure, respectively, muscular and cortical activity, and motion. They will then be asked to walk in a 15 m corridor: (i) self-paced without the exoskeleton (pre-training session); (ii) wearing the exoskeleton and walking with the three modes of use; (iii) self-paced without the exoskeleton (post-training session). From this dataset, we will: (1) quantitatively estimate short-term neuroplasticity of brain connectivity in chronic stroke survivors after a single session of gait training; (2) compare muscle activation patterns during exoskeleton-gait between stroke survivors and age and sex-matched controls; and (3) perform a feasibility analysis on the use of physiological signals to decode gait intentions.

Predictors of Adherence to Lifestyle Recommendations in Stroke Secondary Prevention.

The risk of recurrent vascular events is high following ischaemic stroke or transient ischaemic attack (TIA). Unmanaged modifiable risk factors present opportunities for enhanced secondary prevention. This cross-sectional study (n = 142 individuals post-ischaemic stroke/TIA; mean age 63 years, 70% male) describes adherence rates with risk-reducing behaviours and logistical regression models of behaviour adherence. Predictor variables used in the models com-prised age, sex, stroke/TIA status, aetiology (TOAST), modified Rankin Scale, cardiovascular fit-ness (VO2peak) measured as peak oxygen uptake during incremental exercise (L/min) and Hospital Anxiety and Depression Score (HADS). Of the study participants, 84% abstained from smoking; 54% consumed ≥ 5 portions of fruit and vegetables/day; 31% engaged in 30 min moderate-to-vigorous physical activity (MVPA) at least 3 times/week and 18% were adherent to all three behaviours. VO2peak was the only variable predictive of adherence to all three health behaviours (aOR 12.1; p = 0.01) and to MVPA participation (aOR 7.5; p = 0.01). Increased age (aOR 1.1; p = 0.03) and lower HADS scores (aOR 0.9; p = 0.02) were predictive of smoking abstinence. Men were less likely to consume fruit and vegetables (aOR 0.36; p = 0.04). Targeted secondary prevention interventions after stroke should address cardiovascular fitness training for MVPA and combined health behaviours; management of psychological distress in persistent smokers and consider environmental and social factors in dietary interventions, notably in men.

Patient and public involvement in stroke research: a scoping review protocol.

Background: Growing consensus supports public and patient involvement (PPI) in research as the lived experience of patients, family carers and users of health and social care services bring unique insights to healthcare research. The impact and burden of stroke present ongoing challenges for those living with its consequences and could potentially limit PPI activity. This review aims to explore PPI in published stroke research to identify and describe the extent, nature and design of PPI activities, the type/s of studies involved and the profile of PPI participants engaged in stroke research. Methods: This systematic scoping review, guided by the Arksey & O'Malley five step framework, will be reported according to the PRISMA-ScR reporting guidelines. PPI is embedded at each stage of this proposed scoping review from conceptualisation, participation, contribution and collaboration. The Population, Concept, Context (PCC) structure defines the research question which asks - How is PPI in stroke research currently being conducted and how do the study authors report their PPI activities and its impact? A comprehensive range of electronic databases including PubMed, CINAHL, EMBASE, PsychINFO and the Cochrane Database of Systematic Reviews will generate a broad range of studies. Grey literature (e.g. OpenGrey, Leanus) and internationally recognised stroke organisation websites will be searched for additional research reports. Data extraction will adhere to the Joanna Briggs Institute guidelines, with results collated and mapped to the research cycle stage/s. Conclusions: The outlined scoping review protocol will comprehensively identify and map the existing scientific literature that reports PPI in stroke research. Findings will be presented in relation to PPI conceptualisation, participant profiles and activities in stroke research, volume, type and range of approaches. Knowledge gaps and future priorities for PPI in stroke research will be identified.
