Systematic review of rehabilitation programmes initiated within 90 days of a transient ischaemic attack or 'minor' stroke: a protocol

Lasting impairments following transient ischemic attack and minor stroke: a systematic review protocol

Introduction

The focus on medical management and secondary prevention following Transient Ischemic Attack (TIA) and minor stroke is well-established. Evidence is emerging that people with TIA and minor stroke can experience lasting impairments as fatigue, depression, anxiety, cognitive impairment, and communication difficulties. These impairments are often underrecognized and inconsistently treated. Research in this area is developing rapidly and an updated systematic review is required to evaluate new evidence as it emerges. This living systematic review aims to describe the prevalence of lasting impairments and how they affect the lives of people with TIA and minor stroke. Furthermore, we will explore whether there are differences in impairments experienced by people with TIA compared to minor stroke.

Methods

Systematic searches of PubMed, EMBASE, CINAHL, PsycINFO, Cochrane Libraries will be undertaken. The protocol will follow the Cochrane living systematic review guideline with an update annually. A team of interdisciplinary reviewers will independently screen search results, identify relevant studies based on the defined criteria, conduct quality assessments, and extract data. This systematic review will include quantitative studies on people with TIA and/or minor stroke that report on outcomes in relation to fatigue, cognitive and communication impairments, depression, anxiety, quality of life, return to work/education, or social participation. Where possible, findings will be grouped for TIA and minor stroke and collated according to the time that follow-up occurred (short-term < 3 months, medium-term 3-12 months, and long-term > 12 months). Sub-group analysis on TIA and minor stroke will be performed based on results from the included studies. Data from individual studies will be pooled to perform meta-analysis where possible. Reporting will follow the Preferred Reporting Items for Systematic review and Meta-Analysis Protocol (PRISMA-P) guideline.

Perspectives

This living systematic review will collate the latest knowledge on lasting impairments and how these affect the lives of people with TIA and minor stroke. It will seek to guide and support future research on impairments emphasizing distinctions between TIA and minor stroke. Finally, this evidence will allow healthcare professionals to improve follow-up care for people with TIA and minor stroke by supporting them to identify and address lasting impairments.

B-Type Natriuretic Peptide as a Significant Brain Biomarker for Stroke Triaging Using a Bedside Point-of-Care Monitoring Biosensor

Stroke is a widespread condition that causes 7 million deaths globally. Survivors suffer from a range of disabilities that affect their everyday life. It is a complex condition and there is a need to monitor the different signals that are associated with it. Stroke patients need to be rapidly diagnosed in the emergency department in order to allow the admission of the time-limited treatment of tissue plasminogen activator (tPA). Stroke diagnostics show the use of sophisticated technologies; however, they still contain limitations. The hidden information and technological advancements behind the utilization of biomarkers for stroke triaging are significant. Stroke biomarkers can revolutionize the way stroke patients are diagnosed, monitored, and how they recover. Different biomarkers indicate different cascades and exhibit unique expression patterns which are connected to certain pathologies in the human body. Over the past decades, B-type natriuretic peptide (BNP) and its derivative N-terminal fragment (NT-proBNP) have been increasingly investigated and highlighted as significant cardiovascular biomarkers. This work reviews the recent studies that have reported on the usefulness of BNP and NT-proBNP for stroke triaging. Their classification association is also presented, with increased mortality in stroke, correlation with cardioembolic stroke, and an indication of a second stroke recurrence. Moreover, recent scientific efforts conducted for the technological advancement of a bedside point-of-care (POC) device for BNP and NT-proBNP measurements are discussed. The conclusions presented in this review may hopefully assist in the major efforts that are currently being conducted in order to improve the care of stroke patients.

The Impact of Home-Based Exercise Rehabilitation on Functional Capacity in Patients With Acute Ischemic Stroke: A Randomized Controlled Trial

One of the major consequences of stroke impairments is hemiparesis, which affects activities of daily living and contributes sedentary lifestyle. The purpose of this study was evaluation of the effectiveness of home-based exercise rehabilitation incentive on daily living activities and functional capacity among acute ischemic patients. This randomized controlled trial was done from August 2017 to September 2018. Iranian subjects with unilateral ischemic stroke were recruited from inpatient wards at educational hospital. Patients were randomly assigned to the home-based rehabilitation program (intervention group) or usual care (control group). National Institute of Health Stroke Scale (NIHSS), Barthel Index Score (BI), Modified Rankin Scale (MRS), and Fugl-Meyer Upper and Lower Extremity Sensorimotor Score were evaluated in both groups at baseline and 3 months later. Intervention group received home-based rehabilitation exercise program for 3 months. Control group did not receive home-based rehabilitation program and incentive telephone call. All data were collected and analyzed by SPSS software (Version 20.0; SPSS Inc., Chicago, Illinois) using chi-square test to compare demographic variables, and independent and paired t-tests to between- and within-group assessment, respectively. Forty ischemic stroke patients (20 intervention group and 20 control group) were examined. Results showed BI, Fugl-Meyer Upper and Lower Extremity Score, and MRS score in the interventional group were significantly higher than the control group after 3-month home-based exercise rehabilitation ( p < .001). Providing a home rehabilitation program in this study resulted in a motor recovery on ischemic stroke survivors in the acute phase of recovery. This was assumed to be cost-effective intervention in low-income countries

Randomized Controlled Trial of the Lateral Push-Off Skater Exercise for High-Intensity Interval Training vs Conventional Treadmill Training

OBJECTIVE

To examine the therapeutic effects of the lateral push-off skater exercise vs conventional treadmill training on health-related quality of life, cardiorespiratory fitness (CRF), and balance.

DESIGN

Single-blinded, randomized controlled trial.

SETTING

Outpatient clinic at a tertiary hospital.

PARTICIPANTS

Patients after minor stroke (N=36) with National Institutes of Health Stroke Scale scores≤3 between 20 and 65 years of age were randomly assigned to the intervention group (n=18) or the control group (n=18).

INTERVENTIONS

Thirty-minute sessions of the skater exercise were performed 3 times weekly for 12 weeks in the intervention group. Conventional treadmill aerobic exercise was conducted in the control group at the same frequency and duration as the experimental group exercise.

MAIN OUTCOME MEASURES

The primary outcome was measured using the European Quality of Life-5 Dimension (EQ-5D). Secondary outcomes included CRF and balance indicators. Assessments were performed at baseline (T0), 12 weeks from T0 (T1), and 16 weeks from T0 (T2).

RESULTS

Significant improvements in EQ-5D, peak oxygen uptake (VO₂peak), peak oxygen pulse, peak minute ventilation (VE), Dynamic Gait Index (DGI), and Berg Balance Scale (BBS) were found in the intervention group after performing the skater exercise (P<.05, all), and these improvements were sustained at T2 (P<.05, all). Between-group comparisons demonstrated greater improvements in EQ-5D, VO₂peak, peak oxygen pulse, peak VE, DGI, and BBS in the intervention group than those in the control group at both T1 (P<.05, all) and T2 (P<0.05, all). Correlation analysis showed significant relationships between EQ-5D and VO₂peak, peak VE, DGI, and BBS (P<.05, all).

CONCLUSIONS

The skater exercise improved health-related quality of life, CRF, and balance in patients after minor stroke more effectively than conventional treadmill-based aerobic exercise. We recommend the skater exercise as a high-intensity interval training program for patients after minor stroke.

Secondary prevention lifestyle interventions initiated within 90 days after TIA or 'minor' stroke: a systematic review and meta-analysis of rehabilitation programmes

Background

Strokes are often preceded by a transient ischaemic attack (TIA) or ‘minor’ stroke. The immediate period after a TIA/minor stroke is a crucial time to initiate secondary prevention. However, the optimal approach to prevention, including non-pharmacological measures, after TIA is not clear.

Aim

To systematically review evidence about the effectiveness of delivering secondary prevention, with lifestyle interventions, in comprehensive rehabilitation programmes, initiated within 90 days of a TIA/minor stroke. Also, to categorise the specific behaviour change techniques used.

Design and setting

The review identified randomised controlled trials by searching the Cochrane Library, Ovid MEDLINE, Ovid EMBASE, Web of Science, EBSCO CINAHL and Ovid PsycINFO.

Method

Two review authors independently screened titles and abstracts for eligibility (programmes initiated within 90 days of event; outcomes reported for TIA/minor stroke) and extracted relevant data from appraised studies; a meta-analysis was used to synthesise the results.

Results

A total of 31 potentially eligible papers were identified and four studies, comprising 774 patients post-TIA or minor stroke, met the inclusion criteria; two had poor methodological quality. Individual studies reported increased aerobic capacity but meta-analysis found no significant change in resting and peak systolic blood pressure, resting heart rate, aerobic capacity, falls, or mortality. The main behaviour change techniques were goal setting and instructions about how to perform given behaviours.

Conclusion

There is limited evidence of the effectiveness of early post-TIA rehabilitation programmes with preventive lifestyle interventions. Further robust randomised controlled trials of comprehensive rehabilitation programmes that promote secondary prevention and lifestyle modification immediately after a TIA are needed.

An Analysis of Transient Ischemic Attack Practices: Does Hospital Admission Improve Patient Outcomes?

INTRODUCTION

Immediate treatment has been shown to decrease the recurrence of cerebrovascular accidents following transient ischemic attacks (TIA), prompting the use of a specialized neurologic emergency department (Neuro ED) to triage patients. Despite these findings, there is little evidence supporting the notion that hospital admission improves post-TIA outcomes. Through the lens of a Neuro ED, this retrospective chart review of TIA patients examines whether hospital admission improves 90-day outcomes.

MATERIALS AND METHODS

Two hundred sixty charts of patients discharged with TIA diagnosis were reviewed. These charts encompassed patients with TIA who presented to a main emergency department (ED) or Neuro ED from January 2014 to April 2015. Demographic information, admission ABCD(2) scores, admission National Institutes of Health Stroke Scale scores, and admission Modified Rankin Scale, and reason for any return visits within 90 days were collected.

RESULTS

This review shows that patients triaged by the Neuro ED were admitted at a lower rate than those seen by the standard ED. Further, patients triaged by the Neuro ED experienced lower readmission and recurrence of stroke or TIA within 90 days.

CONCLUSIONS

These results provide preliminary support for the notion that discharging appropriate TIA patients, with adequate follow-up, will not adversely affect the recurrence of TIA or stroke within 90 days.
