Non-pharmacological interventions for preventing secondary vascular events after stroke or transient ischemic attack.

BACKGROUND: Stroke is the second leading cause of death among adults worldwide. Individuals who have suffered a stroke are at high risk of having another stroke likely leading to greater disability and institutionalization. Non-pharmacological interventions may have a role to play in averting a second stroke. OBJECTIVES: To determine the effectiveness of multi-modal programs of non-pharmacological interventions compared with usual care in preventing secondary vascular events and reducing vascular risk factors after stroke or transient ischemic attack (TIA). SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (September 2012); The Cochrane Library databases CENTRAL, CDSR, DARE, HTA and NHS EED (2012 Issue 2); MEDLINE (1950 to February 2012); EMBASE (1974 to February 2012); CINAHL (1982 to February 2012); SPORTDiscus (1800 to February 2012); PsycINFO (1887 to February 2012) and Web of Science (1900 to February 2012). We also searched PEDro, OT Seeker, OpenSIGLE, REHABDATA and Dissertation Abstracts (February 2012). In an effort to identify further published, unpublished and ongoing trials we searched trials registers, scanned reference lists, and contacted authors and researchers. SELECTION CRITERIA: We included randomized controlled trials evaluating the use of non-pharmacological interventions that included components traditionally used in cardiac rehabilitation (CR) programs in adults with stroke or TIA. Primary outcomes were a cluster of second stroke or myocardial infarction or vascular death. Secondary outcomes were (1) secondary vascular events: second stroke, myocardial infarction, and vascular death, as well as (2) vascular risk factors: blood pressure, body weight, lipid profile, insulin resistance and tobacco use. We also recorded adverse events such as exercise-related musculoskeletal injuries or cardiovascular events. DATA COLLECTION AND ANALYSIS: Two review authors independently scanned titles and abstracts and independently screened full reports of studies that were potentially relevant. At each stage, we compared results. The two review authors resolved disagreements through discussion or by involving a third review author. MAIN RESULTS: We identified one study, involving 48 participants, of a 10-week CR program for patients post-stroke that met the inclusion criteria. The results of this completed pilot trial show that patients post-stroke had significantly greater improvement in cardiac risk score in the CR group (13.4 ± 10.1 to 12.4 ± 10.5, P value < 0.05) when compared with usual care (9.4 ± 6.7 to 15.0 ± 6.1, P value < 0.05). In addition, five trials, which are ongoing, will likely meet the inclusion criteria for this review once completed. AUTHORS' CONCLUSIONS: There is limited applicable evidence. Therefore, no implications for practice can be drawn. Further research is required and several trials are underway, the findings of which are anticipated to contribute to the body of evidence.

Development of a digital learning program for physiotherapists to enhance clinical implementation of aerobic exercise in stroke rehabilitation.

BACKGROUND: This paper describes the initial development process of an eLearning continuing professional education program primarily for post-licensure physiotherapists -"Electronic Aerobic Exercise Recommendations to Optimize Best Practices in Care after Stroke" (eAEROBICS). Our objective was to develop an evidence-based, clinically relevant, user-friendly eLearning program for online delivery tailored to facilitate prescription of aerobic exercise post-stroke by physiotherapists. The Demand Driven Learning Model guided curriculum design, delivery, and evaluation. Based on previously identified gaps in physiotherapists' knowledge of aerobic exercise, four learning modules were developed and delivered using an eLearning platform to maximize cost-effectiveness and flexibility. Five physiotherapists volunteered to pilot eAEROBICS, providing preliminary feedback on strengths and suggestions for improvement. RESULTS: Theoretical information and clinical applications addressed the learning objectives of each module in a logical manner. All technical or administrative issues encountered during program delivery were addressed. The feedback from the pilot end-users informed modifications to the eAEROBICS program. CONCLUSIONS: Processes used in developing eAEROBICS have the potential to serve as a model of electronic continuing professional education for other areas of physiotherapy practice. Further investigation of end-user perspectives and clinical impact of the program is warranted to determine the overall effectiveness of the program.

Program of rehabilitative exercise and education to avert vascular events after non-disabling stroke or transient ischemic attack (PREVENT Trial): a multi-centred, randomised controlled trial.

BACKGROUND: Despite lack of outward signs, most individuals after non-disabling stroke (NDS) and transient ischemic attack (TIA) have significant cardiovascular and cerebrovascular disease and are at high risk of a major stroke, hospitalization for other vascular events, or death. Most have multiple modifiable risk factors (e.g., hypertension, physical inactivity, hyperlipidaemia, diabetes, tobacco consumption, psychological stress). In addition, accelerated rates of depression, cognitive decline, and poor quality of sleep have been reported following TIA, which correlate with poor functional outcomes and reduced quality of life. Thus, NSD and TIA are important warning signs that should not be overlooked. The challenge is not unlike that facing other 'silent' conditions - to identify a model of care that is effective in changing people's current behaviors in order to avert further morbidity. METHODS/DESIGN: A single blind, randomized controlled trial will be conducted at two sites to compare the effectiveness of a program of rehabilitative exercise and education versus usual care in modifying vascular risk factors in adults after NDS/TIA. 250 adults within 90 days of being diagnosed with NDS/TIA will be randomly allocated to a 12-week program of exercise and education (PREVENT) or to an outpatient clinic assessment and discussion of secondary prevention recommendations with return clinic visits as indicated (USUAL CARE). Primary outcome measures will include blood pressure, waist circumference, 12-hour fasting lipid profile, and 12-hour fasting glucose/hemoglobin A1c. Secondary measures will include exercise capacity, walking endurance, physical activity, cognitive function, depression, goal attainment and health-related quality of life. Outcome assessment will be conducted at baseline, post-intervention, and 6- and 12-month follow-ups. Direct health care costs incurred over one year by PREVENT versus USUAL CARE participants will also be compared. Ethical approval for the trial has been obtained from the relevant Human Research Ethics Boards. DISCUSSION: Whether timely delivery of an adapted cardiac rehabilitation model is effective in attaining and maintaining vascular risk reduction targets in adults after NDS/TIA is not yet known. We anticipate that the findings of this trial will make a meaningful contribution to the knowledge base regarding secondary stroke prevention.

Aerobic Exercise Recommendations to Optimize Best Practices in Care After Stroke: AEROBICS 2019 Update.

Most stroke survivors have very low levels of cardiovascular fitness, which limits mobility and leads to further physical deconditioning, increased sedentary behavior, and heightened risk of recurrent stroke. Although clinical guidelines recommend that aerobic exercise be a part of routine stroke rehabilitation, clinical uptake has been suboptimal. In 2013, an international group of stroke rehabilitation experts developed a user-friendly set of recommendations to guide screening and prescription-the Aerobic Exercise Recommendations to Optimize Best Practices in Care after Stroke (AEROBICS 2013). The objective of this project was to update AEROBICS 2013 using the highest quality of evidence currently available. The first step was to conduct a comprehensive review of literature from 2012 to 2018 related to aerobic exercise poststroke. A working group of the original consensus panel members drafted revisions based on synthesis. An iterative process was used to achieve agreement among all panel members. Final revisions included: (1) addition of 115 new references to replace or augment those in the original AEROBICS document, (2) rewording of the original recommendations and supporting material, and (3) addition of 2 new recommendations regarding prescription. The quality of evidence from which these recommendations were derived ranged from low to high. The AEROBICS 2019 Update should make it easier for clinicians to screen for, and prescribe, aerobic exercise in stroke rehabilitation. Clinical implementation will not only help to narrow the gap between evidence and practice but also reduce current variability and uncertainty regarding the role of aerobic exercise in recovery after stroke.

Experimental studies of virtual reality-delivered compared to conventional exercise programs for rehabilitation.

This paper presents preliminary data from two clinical trials currently underway using flat screen virtual reality (VR) technology for physical rehabilitation. In the first study, we are comparing a VR-delivered exercise program to a conventional exercise program for the rehabilitation of shoulder joint range-of-motion in patients with chronic frozen shoulder. In the second study, we are comparing two exercise programs, VR and conventional, for balance retraining in subjects post-traumatic brain injury. Effective VR-based rehabilitation that is easily adapted for individuals to use both in inpatient, outpatient and home-based care could be used as a supplement or alternative to conventional therapy. If this new treatment approach is found to be effective, it could provide a way to encourage exercise and treatment compliance, provide safe and motivating therapy and could lead to the ability to provide exercises to clients in distant locations through telehealth applications of VR treatment. VR is a new technology and the possibilities for rehabilitation are only just beginning to be assessed.

Intra- and inter-rater reliability and validity of the Ottawa Sitting Scale: a new tool to characterise sitting balance in acute care patients.

PURPOSE: We present the new Ottawa Sitting Scale (OSS) developed to characterise sitting balance in the acute care setting with slow to recover patients. We provide intra- and inter-rater reliability measures of the OSS as well as a factor analysis of scale items. METHOD: Seventy-one subjects aged 21-92 years participated in this study. Original scores were compared to scores from videotaped original sessions. Performance on the OSS was compared to performance on the Berg Balance Scale (BBS) and the Physiotherapy Functional Mobility Profile (PFMP). RESULTS: The intra-class correlation coefficient (ICC) obtained for intra-rater reliability was excellent at 0.99 with individual item ICCs ranging from 0.746 to 0.997. Similarly, the ICCs for inter-rater reliability were also excellent at 0.96 to 0.98 with individual item ICCs ranging from 0.723 to 0.985. In the factor analysis, two main factors accounted for 77.8% of the total item variance and could be reasonably identified as movement within base of support (BOS) and movement outside BOS. The BBS and the PFMP had floor effects for the subjects with the lowest OSS scores while there was an OSS ceiling effect corresponding to those with BBS scores of approximately 10 or more. CONCLUSIONS: The OSS discriminates between those subjects with low levels of sitting balance. Further studies will determine responsiveness to change, and compare the OSS with other postural control measures to identify the unique application of the OSS through the stages of recovery and rehabilitation.
