Sedentary Behavior in the First Year After Stroke: A Longitudinal Cohort Study With Objective Measures

Cognition and Activity of Daily Living Function in people with Parkinson's disease

The ability to perform activities of daily living (ADL) function is a multifaceted construct that reflects functionality in different daily life situations. The loss of ADL function due to cognitive impairment is the core feature for the diagnosis of Parkinson's disease dementia (PDD). In contrast to Alzheimer's disease, ADL impairment in PD can be compromised by various factors, including motor and non-motor aspects. This narrative review summarizes the current state of knowledge on the association of cognition and ADL function in people with PD and introduces the concept of "cognitive ADL" impairment for those problems in everyday life that are associated with cognitive deterioration as their primary cause. Assessment of cognitive ADL impairment is challenging because self-ratings, informant-ratings, and performance-based assessments seldomly differentiate between "cognitive" and "motor" aspects of ADL. ADL function in PD is related to multiple cognitive domains, with attention, executive function, and memory being particularly relevant. Cognitive ADL impairment is characterized by behavioral anomalies such as trial-and-error behavior or task step omissions, and is associated with lower engagement in everyday behaviors, as suggested by physical activity levels and prolonged sedentary behavior. First evidence shows that physical and multi-domain interventions may improve ADL function, in general, but the evidence is confounded by motor aspects. Large multicenter randomized controlled trials with cognitive ADL function as primary outcome are needed to investigate which pharmacological and non-pharmacological interventions can effectively prevent or delay deterioration of cognitive ADL function, and ultimately the progression and conversion to PDD.

Association Between Lifestyle Behaviors and Obesity Among Stroke Survivors

AIM

The aim was to investigate factors influencing obesity among stroke survivors based on demographics and lifestyle behaviors.

BACKGROUND

Stroke survivors are more likely to experience stroke recurrence within a few years. As obesity is a traditional risk factor for stroke, obesity should be managed in stroke survivors to prevent stroke recurrence.

METHODS

A cross-sectional secondary data analysis analyzed data from the 2017 United States Behavioral Risk Factor Surveillance System (BRFSS) survey. Demographics, frequency of vegetable and fruit intake, smoking, alcohol use, physical activity, and sleep were examined.

RESULTS

Among 1032 stroke survivors, 57.8% were obese. Advanced age, female sex, veteran status, at least once-daily fruit intake, current smoking, and lack of physical activity were associated with obesity.

CONCLUSION

Stroke survivors should be encouraged to pursue healthy behaviors to manage obesity. Appropriate transitional care, including diet education and tailored exercise, can be an effective strategy.

Yoga in the Rehabilitation of Post-Stroke Sequelae: A Non-Inferiority Randomized Controlled Trial

Introduction: Stroke survivors can experience various consequences that affect their physical and psychological balance. Yoga seems to be relevant for this population as it allows to work on both the body and the mind. The first objective of this study was to investigate the non-inferiority of yoga compared with conventional physical activity in improving physical function in patients with chronic post-stroke sequelae. The secondary objective was to investigate the superiority of yoga in improving the mental health of these patients. Methods: A randomized controlled trial was conducted. Thirty-six patients were randomized into two groups to practice a yoga program (YOG'AVC) or the Fitness and Mobility Exercise (FAME) program. Patients were assessed in a blinding mode pre- (T0) and post-program (T1) and 3-4 months after completion (T2). The physical assessments were the Berg Balance Scale, timed up and go test, 6-minute walk test, and quadriceps strength measured by hand-held dynamometer. Questionnaire assessments were: Activities-specific Balance Confidence Scale-Simplified, State-Trait Anxiety Inventory, Beck's Depression Inventory, and the Reintegration to Normal Living Index. Results: The YOG'AVC program was not inferior to the FAME program in improving balance, functional mobility and muscle strength. Both groups showed significant improvement (p < 0.05) between T0 and T1 in their anxiety, depression, and reintegration to normal life scores, with no significant difference between groups. Discussion: Both programs seem to be valuable in improving the physical abilities and psychological well-being of chronic post-stroke patients. However, further studies are required to confirm the difference between these programs.

The relationship between levels of physical activity and participation in everyday life in stroke survivors: A systematic review and meta-analysis

BACKGROUND

Stroke survivors demonstrate decreased physical activity (PA) and take time to return to participation in everyday life, but the relationship between the two variables is unknown.

OBJECTIVE

To investigate the correlation and trajectory over time between levels of PA and participation in everyday life in stroke survivors.

METHODS

PubMed, Web of Science, Scopus, SPORTDiscus, Rehabilitation&Sport Medicine Source, and PEDro databases were searched from inception to January 2024. Cross-sectional and prospective studies evaluating both levels of PA and participation in stroke survivors were included. Two reviewers independently conducted the study selection, data extraction, and quality assessment. Meta-analyses of pooled correlation coefficients were calculated when at least two studies reported a correlation coefficient between the same PA and participation outcomes.

RESULTS

Of 4962 studies identified, 49 were included in the systematic review. Studies were rated high (55%%) or fair (45%) quality. A wide range of monitoring methodologies for assessing PA and participation were found in the 23 prospective studies. Seven studies were included in the meta-analyses, showing a positive moderate correlation between PA time and participation in activities of daily living (n = 148; r = 0.52; P < 0.01; I2 = 81%) in participants <6 months post-stroke, and between PA time and the participation in all areas (n = 126; r = 0.44; P < 0.01; I2 = 0%) in participants ≥6 months post-stroke. Overall, while PA showed significant improvements over time, participation only showed a tendency.

CONCLUSIONS

Despite the heterogeneity, consistent positive associations were found between PA time and participation levels in some areas. Establishing consensus is crucial to reduce heterogeneity and facilitate data pooling.

Mechanisms and benefits of cardiac rehabilitation in individuals with stroke: emerging role of its impact on improving cardiovascular and neurovascular health

Human and animal studies have demonstrated the mechanisms and benefits of aerobic exercise for both cardiovascular and neurovascular health. Aerobic exercise induces neuroplasticity and neurophysiologic reorganization of brain networks, improves cerebral blood flow, and increases whole-body VO2peak (peak oxygen consumption). The effectiveness of a structured cardiac rehabilitation (CR) program is well established and a vital part of the continuum of care for people with cardiovascular disease. Individuals post stroke exhibit decreased cardiovascular capacity which impacts their neurologic recovery and extends disability. Stroke survivors share the same risk factors as patients with cardiac disease and can therefore benefit significantly from a comprehensive CR program in addition to neurorehabilitation to address their cardiovascular health. The inclusion of individuals with stroke into a CR program, with appropriate adaptations, can significantly improve their cardiovascular health, promote functional recovery, and reduce future cardiovascular and cerebrovascular events thereby reducing the economic burden of stroke.

Top-Down and Bottom-Up Mechanisms of Motor Recovery Poststroke

Stroke remains a leading cause of disability. Motor recovery requires the interaction of top-down and bottom-up mechanisms, which reinforce each other. Injury to the brain initiates a biphasic neuroimmune process, which opens a window for spontaneous recovery during which the brain is particularly sensitive to activity. Physical activity during this sensitive period can lead to rapid recovery by potentiating anti-inflammatory and neuroplastic processes. On the other hand, lack of physical activity can lead to early closure of the sensitive period and downstream changes in muscles, such as sarcopenia, muscle stiffness, and reduced cardiovascular capacity, and blood flow that impede recovery.

Integrating Cardiac Rehabilitation in Stroke Recovery

Stroke remains a top contributor to long-term disability in the United States and substantially limits a person's physical activity. Decreased cardiovascular capacity is a major contributing factor to activity limitations and is a significant health concern. Addressing the cardiovascular capacity of stroke survivors as part of poststroke management results in significant improvements in their endurance, functional recovery, and medical outcomes such as all-cause rehospitalization and mortality. Incorporation of a structured approach similar to the cardiac rehabilitation program, including aerobic exercise and risk factor education, can lead to improved cardiovascular function, health benefits, and quality of life in stroke survivors.

Factors related to high-risk movement behaviour in people with stroke who are highly sedentary and inactive

PURPOSE

To identify Capabilities, Opportunities, and Motivational factors influencing movement behaviour throughout the day in people with stroke who are highly sedentary and inactive to enable intervention development.

METHODS

A qualitative study was conducted using semistructured interviews with people with stroke. The interview guide was based on the Capabilities, Opportunities, and Motivation Behavioural model.

RESULTS

Eleven interviews were conducted. Participants reported a lack of knowledge regarding healthy movement behaviour patterns, a lack of insight into their own movement behaviour, and some physical and cognitive limitations to engage in certain physical activities. Several social and environmental elements affecting movement behaviours were mentioned, their impact on movement behaviour varied among participants. Movement behaviour was mostly driven by habits and daily routine, without conscious regulation.

CONCLUSION

Our findings show that people with stroke are unaware of their own movement behaviour or of the consequences of these behaviours on health. Movement behaviour is, for the most part, based on daily routine and personal habits. This indicates the need for a behaviour change intervention. Such interventions will need to include providing information about healthy movement behaviour, feedback on individual's movement behaviour and individualized support, taking into account the social and environmental context and personal capabilities.

Interventions to Change Movement Behaviors After Stroke: A Systematic Review and Meta-analysis

OBJECTIVE

This systematic review aimed to determine which interventions increase physical activity (PA) and decrease sedentary behavior (SB) based on objective measures of movement behavior in individuals with stroke.

DATA SOURCES

The PubMed (Medline), EMBASE, Scopus, CINAHL (EBSCO), and Web of Science databases were searched for articles published up to January 3, 2023.

STUDY SELECTION

The StArt 3.0.3 BETA software was used to screen titles, abstracts, and full texts for studies with randomized controlled trial designs; individuals with stroke (≥18 years of age); interventions aimed at increasing PA or decreasing SB; and objective measurement instruments.

DATA EXTRACTION

Data extraction was standardized, considering participants and assessments of interest. The risk of bias and quality of evidence of the included studies were assessed.

DATA SYNTHESIS

Twenty-eight studies involving 1855 patients were included. Meta-analyses revealed that in the post-stroke acute/subacute phase, exercise interventions combined with behavior change techniques (BCTs) increased both daily steps (standardized mean difference [SMD]=0.65, P=.0002) and time spent on moderate-to-vigorous intensity physical activities (MVPAs) duration of PA (SMD=0.68, P=.0004) with moderate-quality evidence. In addition, interventions based only on BCTs increased PA levels with very low-quality evidence (SMD (low-intensity physical activity)=0.36, P=.02; SMD (MVPA)=0.56, P=.0004) and decreased SB with low-quality evidence (SMD=0.48, P=.03). In the post-stroke chronic phase, there is statistical significance in favor of exercise-only interventions in PA frequency (steps/day) with moderate-quality evidence (SMD=0.68, P=.002). In general, the risk of bias in the included studies was low.

CONCLUSIONS

In the acute/subacute phase after stroke, the use of BCTs combined with exercise can increase the number of daily steps and time spent on MVPA. In contrast, in the post-stroke chronic phase, exercise-only interventions resulted in a significant increase in daily steps.

Reduced physical activity level was associated with poorer quality of life during the early phase of the COVID-19 pandemic: a sub-study of the last-long trial

OBJECTIVES

To assess how physical activity levels changed in a stroke cohort during the COVID-19 (SARS-CoV-2) pandemic, and how these changes were associated with quality of life (QoL).

METHODS

Between March and July 2021, 150 patients with stroke already included in the Life after Stroke (LAST-long) trial in Norway were invited to participate in this cross-sectional survey. Participants were asked to complete a questionnaire assessing changes in physical activity and self-reported health following the pandemic. Univariate and multivariate logistic regression analyses were used to explore the association between physical activity, loneliness, mental health, social activity and QoL.

RESULTS

In all, 118 (79%) participants completed the questionnaire. A total of 80 (68%) reported less physical activity, 46 (39%) felt lonelier, and 43 (37%) reported worse mental health, while 50 (42%) reported reduced QoL compared with before the lockdown. In the univariate analyses less physical activity, feeling lonelier and changes in mental health were associated with reduced QoL. In the multivariate analysis only less physical activity odds ratio (OR) = 4.04 (95% confidence interval (95% CI) 1.44-11.34, p = 0.008) was significantly associated with reduced QoL.

CONCLUSION

More than two-thirds of patients with stroke reported reduced physical activity during the COVID-19 pandemic, and less physical activity was strongly associated with reduced QoL.

Accelerometer-measured physical activity at 3 months as a predictor of symptoms of depression and anxiety 1 year after stroke: a multicentre prospective cohort study in central Norway

OBJECTIVES

To study sedentary behaviour and physical activity at 3 months as predictors for symptoms of depression and anxiety at 1-year post-stroke.

DESIGN

A prospective cohort study.

PATIENTS

Patients with first-ever ischaemic stroke.

METHODS

Mood was assessed 3- and 12-months post-stroke using the Hospital Anxiety and Depression Scale. Sedentary behaviour and physical activity were measured using accelerometry 3 months post-stroke.

RESULTS

A total of 292 participants (116 (39.7%) females; mean age 71.7 (standard deviation 11.3) years) were included. At 12 months, 16.7% experienced depression and 19.5% anxiety, respectively. Adjusting for age and sex, regression analysis showed that comorbidity burden (β 0.26; 95% confidence interval (95% CI) 0.02, 0.51; p = 0.038), stroke severity (β 0.22; 95% CI 0.10, 0.35; p = 0.001), functional disability (β 0.89, 95% CI 0.49, 1.30; p = 0.000), and global cognition (β-0.15; 95% CI -0.25, -0.05; p = 0.004) predicted depression. Multi-adjusted analysis showed sedentary behaviour and physical activity did not significantly predict depression or anxiety (p > 0.05).

CONCLUSION

Sedentary behaviour and physical activity did not significantly predict mood after stroke. Comorbidity burden, stroke severity, functional disability, and global cognition were identified as possible predictors of depression. More research is needed to determine the impact of physical activity on depression and anxiety symptoms.

Intervention to reduce sedentary behaviour and improve outcomes after stroke (Get Set Go): a study protocol for the process evaluation of a pilot cluster randomised controlled trial (RECREATE)

INTRODUCTION

Stroke survivors spend long periods of time engaging in sedentary behaviour (SB) even when their functional recovery is good. In the RECREATE programme, an intervention aimed at reducing SB ('Get Set Go') will be implemented and evaluated in a pragmatic external pilot cluster randomised controlled trial with embedded process and economic evaluations. We report the protocol for the process evaluation which will address the following objectives: (1) describe and clarify causal assumptions about the intervention, and its mechanisms of impact; (2) assess implementation fidelity; (3) explore views, perceptions and acceptability of the intervention to staff, stroke survivors and their carers; (4) establish the contextual factors that influence implementation, intervention mechanisms and outcomes.

METHODS AND ANALYSIS

This pilot trial will be conducted in 15 UK-based National Health Service stroke services. This process evaluation study, underpinned by the Medical Research Council guidance, will be undertaken in six of the randomised services (four intervention, two control). Data collection includes the following: observations of staff training sessions, non-participant observations in inpatient and community settings, semi-structured interviews with staff, patients and carers, and documentary analysis of key intervention components. Additional quantitative implementation data will be collected in all sites. Training observations and documentary analysis data will be summarised, with other observational and interview data analysed using thematic analysis. Relevant theories will be used to interpret the findings, including the theoretical domains framework, normalisation process theory and the theoretical framework of acceptability. Anticipated outputs include the following: recommendations for intervention refinements (both content and implementation); a revised implementation plan and a refined logic model.

ETHICS AND DISSEMINATION

The study was approved by Yorkshire & The Humber - Bradford Leeds Research Ethics Committee (REC reference: 19/YH/0403). Findings will be disseminated via peer review publications, and national and international conference presentations.

Physical activity for obstructive sleep apnea after stroke? A pilot study assessing the contribution of body fluids

PURPOSE

Obstructive sleep apnea (OSA) and physical inactivity are common after stroke. Physical inactivity can lead to/or exacerbate edema following stroke, and the resultant overnight fluid shift may increase the risk of OSA. We aimed to investigate the effect of physical activity on nocturnal rostral fluid shift, sleep pattern, and edematous state of hemiparetic patients.

METHODS

Neck circumference (tape measured) and arms, legs, and trunk fluid volume (bioelectrical impedance spectrum analyzer) were measured before and after 2 polysomnography (PSG) examinations. In the lab, a whole night PSG was performed after the intervention. The intervention consisted of inactivity (lying down and sitting) or activity (standing, performing calf muscle contractions while standing, walking, and climbing stairs) between 13 and 21 h, after the randomization of the participants. With a 7-day interval, participants crossed over to the other group.

RESULTS

From 126 eligible participants, 8 with hemiparetic post-first-ever ischemic stroke at the subacute phase were recruited (age: 53.2 ± 16.2; 6 women). Physical activity reduced AHI from 19 to 13 n°/h and wake after sleep onset from 76.5 to 60.3 min and increased fluid volume of paretic and non-paretic arms and trunk before sleep compared to inactivity.

CONCLUSION

An acute bout of physical activity reduced OSA classification based on AHI (from moderate to mild) and sleep fragmentation. Our results provide preliminary evidence of a possible link between physical activity in patients after stroke as an intervention to counteract OSA severity and improve sleep.

Keeping Active with Texting after Stroke (KATS): development of a text message intervention to promote physical activity and exercise after stroke

BACKGROUND

Post-stroke physical activity reduces disability and risk of further stroke. When stroke rehabilitation ends, some people feel abandoned by services and struggle to undertake physical activities that support recovery and health. The aim of this study was to codesign a novel text message intervention to promote physical activity among people with stroke and provide support when formal rehabilitation ends. This manuscript describes the intervention development processes that will inform future pilot and feasibility studies.

METHODS

The planned intervention was a series of text messages to be sent in a predetermined sequence to people with stroke at the end of rehabilitation. The intervention, underpinned by behaviour change theory and using salient behaviour change techniques, would provide daily messages offering encouragement and support for the uptake and maintenance of physical activity following stroke. The intervention was codesigned by a Collaborative Working Group, comprised of people with stroke, rehabilitation therapists, representatives from stroke charities and academics. A four-step framework was used to design the intervention: formative research on physical activity post-stroke, creation of the behaviour change text message intervention, pre-testing and refinement. Formative research included a review of the scientific evidence and interviews with community-dwelling people with stroke. Data generated were used by the Collaborative Working Group to identify topics to be addressed in the intervention. These were mapped to constructs of the Health Action Process Approach, and salient behaviour change techniques to deliver the intervention were identified. The intervention was rendered into a series of text messages to be delivered over 12 weeks. The draft intervention was revised and refined through an iterative process including review by people with stroke, their spouses, rehabilitation therapists and experts in the field of stroke. The messages encourage regular physical activity but do not prescribe exercise or provide reminders to exercise at specific times. They use conversational language to encourage engagement, and some are personalised for participants. Quotes from people with stroke provide encouragement and support and model key behaviour change techniques such as goal setting and coping planning.

DISCUSSION

Co-design processes were critical in systematically developing this theory and evidence-based intervention. People with stroke and rehabilitation therapists provided insights into perceived barriers post-rehabilitation and identified strategies to overcome them. The structured multistep approach highlighted areas for improvement through successive rounds of review. The intervention will be tested for acceptability, feasibility and effectiveness in future studies. This co-design approach could be used for interventions for other heath behaviours and with different populations.

Multidimensional analysis of sedentary behaviour and participation in Spanish stroke survivors (Part&Sed-Stroke): a protocol for a longitudinal multicentre study

INTRODUCTION

Stroke survivors usually experience long-lasting functional, emotional and social consequences that might contribute to sedentary behaviour and participation restrictions, which are important targets to address during rehabilitation. However, the trajectory and inter-relationship between these factors are unknown.

METHODS AND ANALYSIS

Part&Sed is a research project based on an observational study design with 6 and 12 months of follow-ups in stroke survivors. In addition, a qualitative analysis of the impact of the stroke on the stroke survivor, validation of the Satisfaction with Daily Occupation-Occupational Balance assessment tool and analysis of the reliability of the Fitbit Inspire 2 activity tracker wristband will be carried out. Participants will be chronic stroke survivors with independent walking capacity. Sociodemographic and clinical data, physical activity, ambulation, sleep, quality of life, anxiety and depression, community participation, and occupational satisfaction and balance, as well as data provided by the activity tracker wristband, will be collected. In addition, if the participant has a primary caregiver, the caregiver will also be monitored. A minimum of 130 participants will be recruited to conduct a random-effects multiple regression model. Mixed models for repeated measures will assess the variation over time of the different variables associated with participation and sedentary behaviour. Psychometric properties (eg, internal consistency, construct validity, test-retest reliability) of the Satisfaction with Daily Occupation-Occupational Balance will be determined. Additionally, intraclass correlation coefficients and minimum detectable change will be calculated to assess intrasubject reliability of physical activity and sleep parameters recorded by the Fitbit Inspire 2. The qualitative analysis process will be carried out using the analysis proposed by Giorgi.

ETHICS AND DISSEMINATION

The study received ethical approval from the Spanish Regional Ethics Committee 'Comité de Ética de la Investigación de la Comunidad de Aragón' (PI21/333). The results will be made available via peer-reviewed publications, international conferences and official channels.

Online neuropilates classes in chronic stroke patients: Protocol for a randomised controlled feasibility study

Introduction

Stroke survivors often demonstrate low physical activity levels and experience barriers to physical exercise including embarrassment, low self-efficacy and a shortage of tailored community exercise programmes. Access to physical activity programmes for stroke survivors could be improved by providing tailored, online programmes, although little is known about the safety and feasibility of online exercise classes for stroke survivors. One such programme of exercise which has received little attention in the literature is neuropilates. Neuropilates is the practice of a modified pilates programme in those with neurological conditions and is theorised to have beneficial effects on strength, balance and proprioception in stroke survivors. No previous study has been conducted to investigate online, remotely supervised neuropilates exercise classes in the stroke survivors.

Method and Analysis

This single assessor blinded randomised controlled feasibility study will compare a 6-week online, remotely instructed neuropilates programme to a 6-week online, remotely instructed generalised exercise programme and a 6-week unsupervised generalised home exercise programme in chronic stroke patients. Twenty adults, at least 6 months post stroke, and finished their formal rehabilitation will be recruited to the study. Primary feasibility outcome measures will include patient tolerance of the programme, adherence rates, adverse events, recruitment and retention. Secondary clinical outcomes will include; balance, gait, tone and quality of life. Assessments will be completed at baseline, on programme completion and 3 months post completion by a Physiotherapist blinded to the group allocation.

Ethics and dissemination

This study has received ethical approval from the Sligo University Hospital Ethics committee and ATU ethics board. Results will be published in peer-reviewed journals and presented at national and international conferences.The trial has been registered on clinicaltrials.gov (Identifier: NCT04491279).

WeWalk: walking with a buddy after stroke-a pilot study evaluating feasibility and acceptability of a person-centred dyadic behaviour change intervention

BACKGROUND

Evidence for benefits of physical activity after stroke is unequivocal. However, many people with stroke are inactive, spending > 80% of waking hours sedentary even when they have physical capacity for activity, indicating barriers to physical activity participation that are not physical. WeWalk is a 12-week person-centred dyadic behaviour change intervention in which a person with stroke (PWS) and a walking buddy form a dyad to work together to support the PWS to increase their physical activity by walking outdoors. This pilot study examined the feasibility of recruiting dyads, explored their perceptions of acceptability and their experiences using WeWalk, to identify required refinements before progression to a clinical trial.

METHODS

Design: A single-arm observational pilot study with qualitative evaluation.

INTERVENTION

WeWalk involved facilitated face-to-face and telephone sessions with a researcher who was also a behaviour change practitioner, supported by intervention handbooks and diaries, in which dyads agreed walking goals and plans, monitored progress, and developed strategies for maintaining walking.

EVALUATION

Descriptive data on recruitment and retention were collected. Interview data were collected through semi-structured interviews and analysed using thematic analysis, guided by a theoretical framework of acceptability.

RESULTS

We recruited 21 dyads comprising community dwelling PWS and their walking buddies. Ten dyads fully completed WeWalk before government-imposed COVID-19 lockdown. Despite lockdown, 18 dyads completed exit interviews. We identified three themes: acceptability evolves with experience, mutuality, and person-centredness with personally relevant tailoring. As dyads recognised how WeWalk components supported walking, perceptions of acceptability grew. Effort receded as goals and enjoyment of walking together were realised. The dyadic structure provided accountability, and participants' confidence developed as they experienced physical and psychological benefits of walking. WeWalk worked best when dyads exhibited relational connectivity and mutuality in setting and achieving goals. Tailoring intervention components to individual circumstances and values supported dyads in participation and achieving meaningful goals.

CONCLUSION

Recruiting dyads was feasible and most engaged with WeWalk. Participants viewed the dyadic structure and intervention components as acceptable for promoting outdoor walking and valued the personally tailored nature of WeWalk. Developing buddy support skills and community delivery pathways are required refinements. ISCTRN number: 34488928.

What are the effects of pilates in the post stroke population? A systematic literature review & meta-analysis of randomised controlled trials

OBJECTIVE

Stroke is a leading cause of death and disability worldwide. Pilates, a programme of mind-body exercises is theorised to have beneficial effects on strength, postural control, balance, proprioception, coordination and gait in people with deficits due to a neurological condition. However, the evidence of pilates in stroke patients has never been systemised. The objectives of this systematic literature review are to investigate the effects of pilates in post stroke individuals and compare this intervention to other forms of exercise, standard care and/or physiotherapy.

DATA SOURCES

A comprehensive search was conducted in the following databases: Pubmed (including MEDline), Web of Science, the Cochrane library, Science Direct, Embase and PEDro.

STUDY SELECTION

Studies were selected, screened, filtered and reviewed in detail to identify those that met the inclusion criteria.

DATA EXTRACTION

Data was extracted to a table with specific headings for analysis and studies were rated using the Physiotherapy Evidence Database (PEDro) scale.

DATA SYNTHESIS

Data from a total of 5 included studies with 122 participants was pooled and analysed using the Revman 5 software. Significant findings were found in favour of the pilates intervention groups on balance (P<0.00001), quality of Life (P=0.0002), and gait parameters (P=0.001), when results from the studies were combined and analysed.

CONCLUSIONS

This review found moderate evidence for pilates exercises improving balance in post stroke individuals and limited evidence for improvements in quality of life, cardiopulmonary function and gait. Future studies should examine long term follow up, home programmes and comparisons with other forms of exercise in post stroke patients.

Beyond steps per day: other measures of real-world walking after stroke related to cardiovascular risk

Background

Significant variability exists in how real-world walking has been measured in prior studies in individuals with stroke and it is unknown which measures are most important for cardiovascular risk. It is also unknown whether real-world monitoring is more informative than laboratory-based measures of walking capacity in the context of cardiovascular risk. The purpose of this study was to determine a subset of real-world walking activity measures most strongly associated with systolic blood pressure (SBP), a measure of cardiovascular risk, in people with stroke and if these measures are associated with SBP after accounting for laboratory-based measures of walking capacity.

Methods

This was a cross-sectional analysis of 276 individuals with chronic (≥ 6 months) stroke. Participants wore an activity monitor for ≥ 3 days. Measures of activity volume, activity frequency, activity intensity, and sedentary behavior were calculated. Best subset selection and lasso regression were used to determine which activity measures were most strongly associated with systolic blood pressure. Sequential linear regression was used to determine if these activity measures were associated with systolic blood pressure after accounting for walking capacity (6-Minute Walk Test).

Results

Average bout cadence (i.e., the average steps/minute across all bouts of walking) and the number of long (≥ 30 min) sedentary bouts were most strongly associated with systolic blood pressure. After accounting for covariates (ΔR² = 0.089, p < 0.001) and walking capacity (ΔR² = 0.002, p = 0.48), these activity measures were significantly associated with systolic blood pressure (ΔR² = 0.027, p = 0.02). Higher systolic blood pressure was associated with older age (β = 0.219, p < 0.001), male gender (β = − 0.121, p = 0.046), black race (β = 0.165, p = 0.008), and a slower average bout cadence (β = − 0.159, p = 0.022).

Conclusions

Measures of activity intensity and sedentary behavior may be superior to commonly used measures, such as steps/day, when the outcome of interest is cardiovascular risk. The relationship between walking activity and cardiovascular risk cannot be inferred through laboratory-based assessments of walking capacity.

Feasibility, acceptability, and fidelity of Physical Activity Routines After Stroke (PARAS): a multifaceted behaviour change intervention targeting free-living physical activity and sedentary behaviour in community-dwelling adult stroke survivors

BACKGROUND

Low levels of habitual physical activity and high levels of sedentary behaviour are commonly observed post-stroke. We aimed to assess the feasibility, acceptability and fidelity of a multifaceted, theory- and evidence-informed supported self-management intervention targeting physical activity and sedentary behaviour after stroke: Physical Activity Routines After Stroke (PARAS).

METHODS

Adult stroke survivors and healthcare professionals were recruited from North East England stroke services. Stroke survivor physical activity and sedentary behaviour were targeted by a self-management behavioural intervention supported by healthcare professionals trained in intervention delivery. The main outcomes were protocol and intervention acceptability and feasibility and fidelity of intervention delivery.

RESULTS

Eleven healthcare professionals (9 physiotherapists; 2 occupational therapists) participated in the study. Stroke survivor recruitment was lower than anticipated (19 versus target of up to 35). The healthcare professional training programme was feasible, with fidelity assessment of delivery supporting this finding. Data completeness was acceptable according to a priori criteria (>60%), except for stroke survivor questionnaire return rate (59%) and interview uptake (52%). No serious adverse events occurred. Healthcare professionals and stroke survivors perceived intervention delivery to be feasible and acceptable with minor modifications highlighted including the potential for earlier delivery in the stroke pathway.

CONCLUSIONS

The study protocol and intervention delivery were feasible and acceptable to stroke survivors and healthcare professionals with modifications required before large-scale evaluation.

Predictors of non-stepping time in people with chronic stroke

BACKGROUND

Sedentary time is an independent construct from active time. Previous studies have examined variables associated with sedentary time to inform behavior change programs; however, these studies have lacked data sets that encompass potentially important domains.

OBJECTIVES

The purpose of this study was to build a more comprehensive model containing previously theorized important predictors of sedentary time and new predictors that have not been explored. We hypothesized that variables representing the domains of physical capacity, psychosocial, physical health, cognition, and environmental would be significantly related to sedentary time in individuals post-stroke.

METHODS

This was a cross-sectional analysis of 280 individuals with chronic stroke. An activity monitor was used to measure sedentary (i.e. non-stepping) time. Five domains (8 predictors) were entered into a sequential linear regression model: physical capacity (6-Minute Walk Test, assistive device use), psychosocial (Activities Specific Balance Confidence Scale and Patient Health Questionnaire-9), physical health (Charlson Comorbidity Index and body mass index), cognition (Montreal Cognitive Assessment), and environmental (Area Deprivation Index).

RESULTS

The 6-Minute Walk Test (β = -0.39, p < .001), assistive device use (β = 0.15, p = .03), Patient Health Questionnaire-9 (β = 0.16, p = .01), and body mass index (β = 0.11, p = .04) were significantly related to non-stepping time in individuals with chronic stroke. The model explained 28.5% of the variability in non-stepping time.

CONCLUSIONS

This work provides new perspective on which variables may need to be addressed in programs targeting sedentary time in stroke. Such programs should consider physical capacity, depressive symptoms, and physical health.

We Walk: a person-centred, dyadic behaviour change intervention to promote physical activity through outdoor walking after stroke-an intervention development study

OBJECTIVES

To develop We Walk, a theoretically informed, 12-week person-centred dyadic behaviour change intervention to increase physical activity (PA) in community-dwelling people with stroke (PWS) through outdoor walking.

DESIGN

Three-phase intervention development study. Phase 1: we reviewed literature on barriers and facilitators to PA after stroke and mapped them to the Behaviour Change Wheel and Theoretical Domains Framework to define intervention components. The Health Action Process Approach determined intervention structure underpinned by person-centred principles. Phase 2: stakeholder focus groups involving PWS, their companions and health professionals reviewed the draft intervention, and experts in behaviour change were consulted. Phase 3: informed by phases 1 and 2, the intervention and form of delivery were refined, with final review through patient and public involvement.

SETTING

Three Scottish community rehabilitation stroke services.

PARTICIPANTS

Twenty-three ambulatory community-dwelling PWS and their companions, thirty-seven health and exercise professionals, seven behaviour change experts.

RESULTS

Phase 1 determined key intervention components: information about benefits of walking; developing motivation and confidence to walk; facilitating dyadic goal setting and making plans together; monitoring walking, overcoming challenges; and maintaining walking behaviour. Phase 2 review by stakeholder focus groups and behaviour change experts endorsed intervention components and structure, emphasising dyadic relational aspects as central to potential success. In phase 3, intervention content and handbooks for PWS and buddies were finalised. Healthcare professionals proposed third-sector delivery as most appropriate for intervention delivery. A detailed delivery manual was developed. Participants preferred facilitated face-to-face and telephone delivery.

CONCLUSIONS

Our multilens intervention development approach ensured this novel intervention was evidence-informed, person-centred, theoretically coherent provided appropriate social support, and addressed issues of concern to PWS. This study established intervention components and structure and identified operational issues critical to future success. Future research will pilot and refine We Walk and evaluate acceptability, feasibility, effectiveness and cost-effectiveness.

Physical Activity Behavior of Patients at a Skilled Nursing Facility: Longitudinal Cohort Study

BACKGROUND

On-body wearable sensors have been used to predict adverse outcomes such as hospitalizations or fall, thereby enabling clinicians to develop better intervention guidelines and personalized models of care to prevent harmful outcomes. In our previous work, we introduced a generic remote patient monitoring framework (Sensing At-Risk Population) that draws on the classification of human movements using a 3-axial accelerometer and the extraction of indoor localization using Bluetooth low energy beacons, in concert. Using the same framework, this paper addresses the longitudinal analyses of a group of patients in a skilled nursing facility. We try to investigate if the metrics derived from a remote patient monitoring system comprised of physical activity and indoor localization sensors, as well as their association with therapist assessments, provide additional insight into the recovery process of patients receiving rehabilitation.

OBJECTIVE

The aim of this paper is twofold: (1) to observe longitudinal changes of sensor-based physical activity and indoor localization features of patients receiving rehabilitation at a skilled nursing facility and (2) to investigate if the sensor-based longitudinal changes can complement patients' changes captured by therapist assessments over the course of rehabilitation in the skilled nursing facility.

METHODS

From June 2016 to November 2017, patients were recruited after admission to a subacute rehabilitation center in Los Angeles, CA. Longitudinal cohort study of patients at a skilled nursing facility was followed over the course of 21 days. At the time of discharge from the skilled nursing facility, the patients were either readmitted to the hospital for continued care or discharged to a community setting. A longitudinal study of the physical therapy, occupational therapy, and sensor-based data assessments was performed. A generalized linear mixed model was used to find associations between functional measures with sensor-based features. Occupational therapy and physical therapy assessments were performed at the time of admission and once a week during the skilled nursing facility admission.

RESULTS

Of the 110 individuals in the analytic sample with mean age of 79.4 (SD 5.9) years, 79 (72%) were female and 31 (28%) were male participants. The energy intensity of an individual while in the therapy area was positively associated with transfer activities (β=.22; SE 0.08; P=.02). Sitting energy intensity showed positive association with transfer activities (β=.16; SE 0.07; P=.02). Lying down energy intensity was negatively associated with hygiene activities (β=-.27; SE 0.14; P=.04). The interaction of sitting energy intensity with time (β=-.13; SE 0.06; P=.04) was associated with toileting activities.

CONCLUSIONS

This study demonstrates that a combination of indoor localization and physical activity tracking produces a series of features, a subset of which can provide crucial information to the story line of daily and longitudinal activity patterns of patients receiving rehabilitation at a skilled nursing facility. The findings suggest that detecting physical activity changes within locations may offer some insight into better characterizing patients' progress or decline.

Stroke Recovery During the COVID-19 Pandemic: A Position Paper on Recommendations for Rehabilitation

Health care delivery shifted and adapted with the COVID-19 pandemic caused by the novel severe acute respiratory syndrome coronavirus 2. Stroke care was negatively affected across the care continuum and may lead to poor community living outcomes in those who survived a stroke during the ongoing pandemic. For instance, delays in seeking care, changes in length of stays, and shifts in discharge patterns were observed during the pandemic. Those seeking care were younger and had more severe neurologic effects from stroke. Increased strain was placed on caregivers and public health efforts, and community-wide lockdowns, albeit necessary to reduce the spread of COVID-19, had detrimental effects on treatment and recommendations to support community living outcomes. The American Congress of Rehabilitation Medicine Stroke Interdisciplinary Special Interest Group Health and Wellness Task Force convened to (1) discuss international experiences in stroke care and rehabilitation and (2) review recently published literature on stroke care and outcomes during the pandemic. Based on the findings in the literature, the task force proposes recommendations and interdisciplinary approaches at the (1) institutional and societal level; (2) health care delivery level; and (3) individual and interpersonal level spanning across the care continuum and into the community.

Movement behavior patterns composition remains stable, but individuals change their movement behavior pattern over time in people with a first-ever stroke

BACKGROUND

Movement behaviors (i.e., physical activity levels, sedentary behavior) in people with stroke are not self-contained but cluster in patterns. Recent research identified three commonly distinct movement behavior patterns in people with stroke. However, it remains unknown if movement behavior patterns remain stable and if individuals change in movement behavior pattern over time.

OBJECTIVES

1) To investigate the stability of the composition of movement behavior patterns over time, and 2) determine if individuals change their movement behavior resulting in allocation to another movement behavior pattern within the first two years after discharge to home in people with a first-ever stroke.

METHODS

Accelerometer data of 200 people with stroke of the RISE-cohort study were analyzed. Ten movement behavior variables were compressed using Principal Componence Analysis and K-means clustering was used to identify movement behavior patterns at three weeks, six months, one year, and two years after home discharge. The stability of the components within movement behavior patterns was investigated. Frequencies of individuals' movement behavior pattern and changes in movement behavior pattern allocation were objectified.

RESULTS

The composition of the movement behavior patterns at discharge did not change over time. At baseline, there were 22% sedentary exercisers (active/sedentary), 45% sedentary movers (inactive/sedentary) and 33% sedentary prolongers (inactive/highly sedentary). Thirty-five percent of the stroke survivors allocated to another movement behavior pattern within the first two years, of whom 63% deteriorated to a movement behavior pattern with higher health risks. After two years there were, 19% sedentary exercisers, 42% sedentary movers, and 39% sedentary prolongers.

CONCLUSIONS

The composition of movement behavior patterns remains stable over time. However, individuals change their movement behavior. Significantly more people allocated to a movement behavior pattern with higher health risks. The increase of people allocated to sedentary movers and sedentary prolongers is of great concern. It underlines the importance of improving or maintaining healthy movement behavior to prevent future health risks after stroke.

The Active Hospital pilot: A qualitative study exploring the implementation of a Trust-wide Sport and Exercise Medicine-led physical activity intervention

BACKGROUND

In 2017 Public Health England and Sport England commissioned a Consultant-led Sport and Exercise Medicine (SEM) pilot to test the feasibility and acceptability of embedding physical activity interventions in secondary care clinical pathways. The aim of this paper is to report qualitative findings exploring the experience of healthcare professionals (HCPs) and patients involved in the Active Hospital pilot.

METHODS

Qualitative data was collected by semi-structured interviews with Active Hospital pilot SEM Consultants, and staff and patients involved in three clinical pathways. Interviews with SEM Consultants explored the experience of developing and implementing the pilot. Interviews with staff and patients explored the experience of delivering and receiving Active Hospital interventions. Data were analysed thematically.

RESULTS

Interviews identified the importance of the Active Hospital pilot being Consultant-led for the following reasons; i) having trusting relationships with decision makers, ii) having sufficient influence to effect change, iii) identifying champions within the system, and iv) being adaptable to change and ensuring the programme fits within the wider strategic frameworks. HCPs emphasised the importance of the Active Hospital interventions fitting easily within existing work practices, the need for staff training and to tailor interventions for individual patient needs. The Active Hospital pilot was well received by patients, however a lack of dedicated resource and capacity to deliver the intervention was highlighted as a challenge by both patients and HCPs.

CONCLUSION

The SEM Consultants' ability to navigate the political climate of a large National Health Service (NHS) Trust with competing agendas and limited resource was valuable. The interventions were well received and a valued addition to usual clinical care. However, implementation and ongoing delivery of the pilot encountered challenges including lack of capacity within the system and delays with recruiting to the delivery teams in each pathway.

Approaches to Promote Reduction in Sedentary Behavior in Patients With Minor Ischemic Stroke: A Randomized Controlled Trial

OBJECTIVE

The purpose of this study was to determine whether an approach that promotes reduction in sedentary behavior (SB) during hospitalization and after hospital discharge reduces SB in patients with minor ischemic stroke (MIS) compared with an approach that promotes an increase in physical activity levels.

DESIGN

Randomized controlled trial design.

SETTING

During hospitalization and after hospital discharge.

PARTICIPANTS

We randomly assigned patients (N=61) with MIS (average age, 71.3±8.3y; 65.6% men) admitted to an acute hospital to either the intervention group (reduced SB, n=31) or the control group (increased physical activity levels, n=30).

INTERVENTIONS

During hospitalization, the intervention group received education on reducing SB, goal setting for SB after hospital discharge, and self-monitoring of SB and step count. In contrast, the control group received education on increasing physical activity levels and self-monitoring of step count. Patients in both groups wore an accelerometer during hospitalization until 3 months after hospital discharge. The intervention group received self-monitoring of SB and step count, stickers including information about reducing their SB, and phone calls once every 2 weeks for encouragement and feedback. The control group only wore the accelerometer.

MAIN OUTCOME MEASURES

The primary outcome was SB (in percentage) at 3 months after hospital discharge.

RESULTS

There was an interaction between the 2 groups for SB. Compared with the control group, the intervention group showed a significantly reduced SB (intervention group: baseline, 70.5%; 3 months after hospital discharge, 48.6%; control group: baseline, 71.5%; 3 months after hospital discharge, 57.5%; F value=5.981; P=.018).

CONCLUSIONS

The results suggested that an approach that promotes SB reduction during hospitalization and after hospital discharge is effective in reducing SB in patients with MIS 3 months after hospital discharge.

Using Intervention Mapping to develop and implement a home-based sedentary behavior change intervention after stroke

Prolonged sedentary behavior is a problem immediately following a stroke and it persists from the acute to chronic phases of recovery. Frequently interrupting sedentary time might help to mitigate the associated detrimental health consequences. The purpose of this article was to describe the process followed in the systematic development and implementation of a theory- and home-based sedentary behavior change intervention for people with stroke. The Intervention Mapping protocol was used to design, develop and implement a STand Up Frequently From Stroke (STUFFS) program aimed at reducing prolonged sedentary behavior after stroke. A qualitative inquiry with people with stroke (n = 13) informed the development of the intervention. The systematic approach followed in the development process including the theoretical basis, content development, and evaluation planning were described. Program reception was assessed using thematic content analysis of exit-interview data (n = 25). The 8-weeks STUFFS intervention is a home-based sedentary behavior change program that provides education about the risks of prolonged sedentary behavior and facilitates behavior change, including the use of motivational tools to empower people with stroke to reduce sedentary behavior. The program was well-received and acceptable to people with stroke (89% satisfaction). This article provides information that furthers knowledge about theory-based strategies to reduce sedentary behavior in the home environment after stroke and facilitates implementation of this type of intervention.

Serum activity of matrix metalloproteinase-2 and -9 is increased in chronic post-stroke individuals: a cross-sectional exploratory study

BACKGROUND

High concentrations of matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) are associated with inflammation early after stroke. In chronic stages, the elevation of some cytokines is related to the presence of co-morbid conditions in these individuals. In addition to this, some characteristics such as sensorimotor impairment, atrophy, and sedentary lifestyle predispose the system to an inflammatory response.

OBJECTIVE

To quantify MMP-2 and -9 serum activity in chronic post-stroke individuals and correlate it with variables of physical activity level, body composition, functional and walking capacity, and with inflammatory biomarkers. Additionally, gelatinase activity was characterized according to motor impairment.

METHODS

Fourteen patients with stroke onset >6 months and seven healthy individuals were enrolled in this study. The clinical assessment included: body composition, measure by bioelectrical impedance analyzer; Fugl-Meyer Motor Assessment Scale; six-minute and ten-meter walk tests, and physical activity level assessed by the StepWatch® Activity Monitor. Blood samples were collected from antecubital vein and serum MMP-2 and -9 activity was analyzed using gelatin Zymography, and the TNFα, IL-6, IL-1β, IL-10 biomarkers using ELISA kits.

RESULTS

Chronic post-stroke individuals presented an increased activity of MMP-2 and -9 compared to healthy individuals. Positive correlations with time and steps in low cadence and negative ones with medium cadence and peak activity index were observed. According to the motor impairment, the MMP-2 activity was increased in the mild-moderate group compared to the control group.

CONCLUSION

Increased gelatinases in chronic post-stroke individuals could describe an inflammation process related to the limited capacity of walking in high intensities.

Recent Trends in Sedentary Time: A Systematic Literature Review

This paper systematically reviews and synthesizes the relevant literature on sedentary time research. A bibliometric analysis was conducted to evaluate the publications from 2010 to 2020 in the Web of Science (WoS) core collection database. Derwent Data Analyzer software was used for the cleaning, mining, and visualization of the data. Historical trends of the topics, main contributors, leading countries, leading institutions, leading research areas, and journals were explored. A total of 3020 publications were studied. The United States, the United Kingdom, and Australia are the three most productive countries. The Australian institution Baker Heart and Diabetes Institute led the list of productive institutions, and Ekelund U published the most papers. Sedentary time raised the concerns of scholars from 106 research areas, and public health was the dominant field. Physical activity, accelerometer, children, and obesity were the most frequently used keywords. The findings suggest that sedentary time is rapidly emerging as a global issue that has detrimental effects on public health. The hotspots shifted in the past 10 years, and COVID-19 was the most popular topic of sedentary time research.

A qualitative study of sedentary behaviours in stroke survivors: non-participant observations and interviews with stroke service staff in stroke units and community services

PURPOSE

Sedentary behaviour (SB) is associated with negative health outcomes and is prevalent post-stroke. This study explored SB after stroke from the perspective of stroke service staff.

METHODS

Qualitative mixed-methods study. Non-participant observations in two stroke services (England/Scotland) and semi-structured interviews with staff underpinned by the COM-B model of behaviour change. Observations were analysed thematically; interviews were analysed using the Framework approach.

RESULTS

One hundred and thirty-two observation hours (October - December 2017), and 31 staff interviewed (January -June 2018). Four themes were identified: (1) Opportunities for staff to support stroke survivors to reduce SB; (2) Physical and psychological capability of staff to support stroke survivors to reduce SB; (3) Motivating factors influencing staff behaviour to support stroke survivors to reduce SB; (4) Staff suggestions for a future intervention to support stroke survivors to reduce SB.

CONCLUSIONS

Staff are aware of the consequences of prolonged sitting but did not relate to SB. Explicit knowledge of SB was limited. Staff need training to support stroke survivors to reduce SB. Sedentary behaviour in the community was not reported to change markedly, highlighting the need to engage stroke survivors in movement from when capable in hospital, following through to home.Implications for rehabilitationStroke survivor sedentary behaviour is influenced, directly and indirectly, by the actions and instructions of stroke service staff in the inpatient and community setting.The built and social environment, both in the inpatient and community settings, may limit opportunities for safe movement and can result in stroke survivors spending more time sedentary.Stroke service staff appreciate the benefit of encouraging stroke survivors to stand and move more, if it is safe for them to do so.Staff would be amenable to encourage stroke survivors to reduce sedentary behaviour, provided they have the knowledge and resources to equip them to support this.

Comparing the physical activity of stroke survivors in high-income countries and low to middle-income countries

BACKGROUND

Low physical activity levels in people with stroke may contribute to higher risk of cardiovascular disease morbidity and mortality. Differences in economic status, culture and the built environment may influence the applicability of interventions developed in high income countries (HIC) for stroke survivors in low to middle-income countries (LMIC).

PURPOSE

To compare physical activity levels of stroke survivors in HIC and LMIC and to explore the influence of lower limb impairment on physical activity levels.

METHODS AND MATERIALS

An exploratory secondary analysis of observational data on physical activity levels of stroke survivors from Australia (HIC) and India (LMIC). Physical activity variables (step count, light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA)) were measured by accelerometery. Comparisons of physical activity levels between (a) Australian and Indian stroke survivors and (b) participants with and without lower limb impairments were performed using independent t-tests or Mann-Whitney U tests.

RESULTS

There were no significant differences in physical activity levels between (i) Australian and Indian stroke survivors (step count mean difference 201 steps [-1375 to 974], LPA mean difference -24 min [-22 to 69], MVPA mean difference 2 min [-8 to 3]), and (ii) stroke survivors with and without lower limb impairments in either country.

CONCLUSION

Stroke survivors were highly inactive in both countries. Despite differences in economic status, cultural influences and the built environment, the physical activity of stroke survivors in Australia and India did not differ. People with and without lower limb impairment also had similar physical activity levels.

An Exploration of Sedentary Behavior Patterns in Community-Dwelling People With Stroke: A Cluster-Based Analysis

BACKGROUND AND PURPOSE

Long periods of daily sedentary time, particularly accumulated in long uninterrupted bouts, are a risk factor for cardiovascular disease. People with stroke are at high risk of recurrent events and prolonged sedentary time may increase this risk. We aimed to explore how people with stroke distribute their periods of sedentary behavior, which factors influence this distribution, and whether sedentary behavior clusters can be distinguished?

METHODS

This was a secondary analysis of original accelerometry data from adults with stroke living in the community. We conducted data-driven clustering analyses to identify unique accumulation patterns of sedentary time across participants, followed by multinomial logistical regression to determine the association between the clusters, and the total amount of sedentary time, age, gender, body mass index (BMI), walking speed, and wake time.

RESULTS

Participants in the highest quartile of total sedentary time accumulated a significantly higher proportion of their sedentary time in prolonged bouts (P < 0.001). Six unique accumulation patterns were identified, all of which were characterized by high sedentary time. Total sedentary time, age, gender, BMI, and walking speed were significantly associated with the probability of a person being in a specific accumulation pattern cluster, P < 0.001 - P = 0.002.

DISCUSSION AND CONCLUSIONS

Although unique accumulation patterns were identified, there is not just one accumulation pattern for high sedentary time. This suggests that interventions to reduce sedentary time must be individually tailored.Video Abstract available for more insight from the authors (see the Video Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A343).

The Effects of Interrupting Prolonged Sitting With Frequent Bouts of Light-Intensity Standing Exercises on Blood Pressure in Stroke Survivors: A Dose Escalation Trial

BACKGROUND

Interrupting prolonged sitting acutely lowers blood pressure in nonstroke populations. However, the dose-response effect in stroke survivors is unknown. The authors investigated different doses of light-intensity standing exercises that interrupt prolonged sitting and reduce blood pressure immediately and over 24 hours in stroke survivors.

METHODS

Within-participant, laboratory-based, dose escalation trial. Conditions (8 h) were prolonged sitting and 2 experimental conditions of standing exercises with increasing frequency (3 cohorts, 2 × 5 min to 6 × 5 min). The primary outcome is the mean systolic blood pressure.

RESULTS

Twenty-nine stroke survivors (aged 66 [12] y) participated. Frequent bouts of standing exercises lowered the mean systolic blood pressure following the 4 × 5-minute (-2.1 mm Hg; 95% confidence interval [CI], -3.6 to -0.6) and 6 × 5-minute conditions (-2.3 mm Hg; 95% CI, -4.2 to -0.5) compared with prolonged sitting. Diastolic blood pressure was lowered following the 6 × 5-minute condition (-1.4 mm Hg; 95% CI, -2.7 to -0.2). The 24-hour systolic blood pressure increased following the 2 × 5-minute condition (6.9 mm Hg; 95% CI, 3.1 to 10.6).

CONCLUSIONS

Interrupting prolonged sitting with more frequent bouts of standing exercises lowers systolic and diastolic blood pressure in stroke survivors. However, reductions may only be short term, and investigations on sustained effects are warranted.

Interventions for reducing sedentary behaviour in people with stroke

BACKGROUND

Stroke survivors are often physically inactive as well as sedentary,and may sit for long periods of time each day. This increases cardiometabolic risk and has impacts on physical and other functions. Interventions to reduce or interrupt periods of sedentary time, as well as to increase physical activity after stroke, could reduce the risk of secondary cardiovascular events and mortality during life after stroke.

OBJECTIVES

To determine whether interventions designed to reduce sedentary behaviour after stroke, or interventions with the potential to do so, can reduce the risk of death or secondary vascular events, modify cardiovascular risk, and reduce sedentary behaviour.

SEARCH METHODS

In December 2019, we searched the Cochrane Stroke Trials Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, Conference Proceedings Citation Index, and PEDro. We also searched registers of ongoing trials, screened reference lists, and contacted experts in the field.

SELECTION CRITERIA

Randomised trials comparing interventions to reduce sedentary time with usual care, no intervention, or waiting-list control, attention control, sham intervention or adjunct intervention. We also included interventions intended to fragment or interrupt periods of sedentary behaviour.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies and performed 'Risk of bias' assessments. We analyzed data using random-effects meta-analyses and assessed the certainty of the evidence with the GRADE approach.

MAIN RESULTS

We included 10 studies with 753 people with stroke. Five studies used physical activity interventions, four studies used a multicomponent lifestyle intervention, and one study used an intervention to reduce and interrupt sedentary behaviour. In all studies, the risk of bias was high or unclear in two or more domains. Nine studies had high risk of bias in at least one domain. The interventions did not increase or reduce deaths (risk difference (RD) 0.00, 95% confidence interval (CI) -0.02 to 0.03; 10 studies, 753 participants; low-certainty evidence), the incidence of recurrent cardiovascular or cerebrovascular events (RD -0.01, 95% CI -0.04 to 0.01; 10 studies, 753 participants; low-certainty evidence), the incidence of falls (and injuries) (RD 0.00, 95% CI -0.02 to 0.02; 10 studies, 753 participants; low-certainty evidence), or incidence of other adverse events (moderate-certainty evidence). Interventions did not increase or reduce the amount of sedentary behaviour time (mean difference (MD) +0.13 hours/day, 95% CI -0.42 to 0.68; 7 studies, 300 participants; very low-certainty evidence). There were too few data to examine effects on patterns of sedentary behaviour. The effect of interventions on cardiometabolic risk factors allowed very limited meta-analysis.

AUTHORS' CONCLUSIONS

Sedentary behaviour research in stroke seems important, yet the evidence is currently incomplete, and we found no evidence for beneficial effects. Current World Health Organization (WHO) guidelines recommend reducing the amount of sedentary time in people with disabilities, in general. The evidence is currently not strong enough to guide practice on how best to reduce sedentariness specifically in people with stroke. More high-quality randomised trials are needed, particularly involving participants with mobility limitations. Trials should include longer-term interventions specifically targeted at reducing time spent sedentary, risk factor outcomes, objective measures of sedentary behaviour (and physical activity), and long-term follow-up.

Ambulatory activity in stroke survivors associated with functional outcome and quality of life: an observational cohort study

BACKGROUND

Physical activity is beneficial in stroke prevention and recovery. Understanding activity dynamics and its effect on outcome after stroke is important to improve recommendations and develop interventions.

OBJECTIVES

We examined serial changes in daily ambulatory activity (AA) averaged over 1 week in people with subacute to chronic stroke and its association with functional outcome (modified Rankin scale [mRS]) and quality of life (EQ-5D-3L).

METHODS

This observational study examined AA in stroke survivors with no to moderate disability (US National Institute of Stroke Scale [NIHSS] score) who were mostly community dwelling and had cryptogenic stroke based on data from the Continuous Cardiac Monitoring to Assess Atrial Fibrillation After Cryptogenic Stroke study. The participants underwent long-term AA monitoring by accelerometric activity data obtained from an insertable cardiac monitor without receiving any specific encouragement regarding physical activity. We analysed AA changes and assessed the association between baseline AA and mRS/EQ-5D-3L scores. A small group of participants had follow-up data for 2 years, which allowed for analysing long-term serial changes.

RESULTS

We included 186 participants (mean [SD] age 61.3 [11.2] years, 67% male, mean 39 [28] days after stroke). AA increased during the subacute phase in individuals with mild (NIHSS score 1-4, p<0.001) and moderate (NIHSS score 5-10, p=0.013) disability but not in the non-impaired group. Baseline AA was inversely associated with NIHSS score (p<0.001) and was associated with mRS score (p=0.001) and weakly correlated with EQ-5D-3L score at 6 months (p=0.032, r=0.22). For the 45 participants with follow-up data (mean age 64.5 [9.7] years, 80% male, mean 34 [21] days after stroke), AA remained stable.

CONCLUSION

AA increased in stroke survivors with impairments but remained stable in those whose symptoms had resolved. AA during the early subacute period was associated with mRS and EQ-5D-3L scores at 6 months. Insertable cardiac monitoring offers a feasible method for monitoring activity over prolonged periods in people after stroke. Its increased use may offer an opportunity to overcome the limited reliability and validity of many existing measures.

The course of physical functioning in the first two years after stroke depends on peoples' individual movement behavior patterns

BACKGROUND AND PURPOSE

Deterioration of physical functioning after stroke in the long term is regarded as a major problem. Currently, the relationship between "peoples'" movement behavior patterns (the composition of sedentary behavior and physical activity during waking hours) directly after stroke and the development of physical functioning over time is unknown. Therefore, the objectives of this study were to investigate (1) the course of physical functioning within the first two years after returning home after stroke, and (2) the association between physical functioning and baseline movement behavior patterns.

METHOD

In the longitudinal RISE cohort study, 200 persons with a first-ever stroke discharged to the home-setting were included. Participants' physical functioning was assessed within three weeks, at six months, and one and two years after discharge using the Stroke Impact Scale (SIS) 3.0 subscale physical and the five-meter walk test (5MWT). Three distinct movement behavior patterns were identified in a previous study at baseline and were used in the current study: (1) sedentary exercisers (sufficiently active and 64% of waking hours sedentary), (2) sedentary movers' (inactive and 63% of waking hours sedentary), and (3) sedentary prolongers (inactive and >78% of waking hours sedentary accumulated in long prolonged bouts). The association between movement behavior patterns and the course of physical functioning was determined using longitudinal generalized estimating equations analyses.

RESULTS

Overall participants' physical functioning increased between discharge and six months and declined from six months up to two years. Physical functioning remained stable during the first two years after stroke in sedentary exercisers. Physical functioning improved during the first six months after discharge in sedentary movers and sedentary prolongers and deteriorated in the following six months. Only physical functioning (SIS) of sedentary prolongers further declined from one up to two years. A similar pattern was observed in the 5MWT.

CONCLUSION

Movement behavior patterns identified directly after returning home in people with stroke are associated with and are predictive of the course of physical functioning. Highly sedentary and inactive people with stroke have unfavorable outcomes over time than individuals with higher amounts of physical activity.

Nonleisure-Time Physical Activity Guidance Following Minor Ischemic Stroke: A Randomized Clinical Trial

The purpose of this single-masked randomized clinical trial was to examine whether nonleisure-time physical activity guidance (NLTPAG) improves physical activity levels in patients after minor ischemic stroke. Patients who had been hospitalized for minor ischemic stroke in an acute care hospital (National Health Institute Stroke Scale ≤ 5) were randomized to either an NLTPAG group (n = 17) or a leisure-time physical activity guidance group (n = 16). NLTPAG focused on reducing sedentary behavior and increasing the frequency of walking for shopping and household activities to improve physical activity levels in daily life. Physical activity levels significantly improved only in participants in the NLTPAG group (initial assessment: metabolic equivalents of task = 12.6; final assessment: metabolic equivalents of task = 14.8; p = .035, r = .51). These results suggest that NLTPAG may be effective for improving physical activity levels in patients after minor ischemic stroke.

Longer-term health and social care strategies for stroke survivors and their carers: the LoTS2Care research programme including cluster feasibility RCT

Background

It is reported that the longer-term outcomes for stroke survivors are poor, with a range of unmet needs identified.

Objectives

The aims were to develop and test a longer-term stroke care strategy focused on improving the quality of life of stroke survivors and their carers by addressing unmet needs, and maintenance and enhancement of participation (i.e. involvement in life situations).

Design

Five overlapping workstreams were undertaken – (1) refinement of content by semistructured interviews with stroke survivors and their carers and by a review of the literature to inform content and delivery of the care strategy; (2) exploration of service models by national survey and focus groups with purposely selected services; (3) intervention development by interaction with a reference group of stroke survivors, carers, and health and social care professionals; (4) refinement and pilot implementation of the developed intervention in three stroke services (case studies); and (5) a cluster randomised controlled feasibility trial in 10 stroke services across England and Wales.

Setting

The intervention development work and feasibility trial were in stroke services (inclusive of primary, secondary, community and social care provision) across England and Wales.

Participants

Participants were stroke survivors resident in the community and their carers, and health and social care professionals in the included stroke services.

Data sources

Interviews with 28 stroke survivors and their carers at least 9 months post stroke ascertained their needs and the barriers to and facilitators of addressing those needs. Additional literature reviews identified 23 needs. No evidence-based interventions to address these needs were reported; self-management was highlighted as a possible delivery mechanism. In workstream 2, a national survey revealed that the most common model of stroke service provision was care up to 12 months post stroke, reported by 46 (40%) services. Thirty-five (30%) services provided care up to 6 months post stroke and 35 (30%) provided care beyond 12 months, thus identifying 6 months post stroke as an appropriate delivery point for a new intervention. Through focus groups in a range of services, stroke survivors’ perceived unmet needs and the barriers to and enablers of service provision were identified.

Intervention

Using information obtained in workstreams 1 and 2 and working closely with a stakeholder reference group, we developed an intervention based on the unmet needs prioritised by stroke survivors and their carers (workstream 3). In workstream 4, action groups (clinicians, stroke survivors and researchers) were established in three stroke services that led implementation in their service and contributed to the iterative refinement of the intervention, associated training programme and implementation materials. The intervention (called New Start) was delivered at 6 months post stroke. Key components were problem-solving self-management with survivors and carers, help with obtaining usable information, and helping survivors and their carers build sustainable, flexible support networks.

Results

A cluster randomised feasibility trial (workstream 5) was successfully implemented in 10 stroke services across England and Wales, with associated process and health economic evaluations. Five services were randomised to provide New Start, while five continued with usual care; 269 participants were recruited. Progression criteria – in terms of our pre-determined (red, amber, green) criteria for progress to a full trial: target stroke survivor recruitment rates were achieved, on average, across sites (24.1 per site over 6 months, green); 216 (80.3%) registered stroke survivors returned follow-up questionnaires at 9 months (84.1% in the intervention arm and 75.8% in the usual care arm, green); according to data reported by sites, overall, 95.2% of registered stroke survivors were offered at least one session of the intervention (green); all five intervention sites had at least two facilitators deemed competent, delivered the New Start intervention and provided it to stroke survivors (green). However, at some sites, there were concerns regarding the number of stroke survivors being offered, accepting and receiving the intervention. Only small differences in outcomes and costs were observed between the New Start and usual care groups, and considerable uncertainty around the cost-effectiveness remains.

Conclusions

We report a complex programme of work that has described the longer-term needs of stroke survivors and highlighted evidence and service gaps. Working closely with stroke survivors, an intervention was developed that has been refined in three services and feasibility tested in a cluster randomised controlled trial. Further refinement of the target population and optimisation of the intervention materials is required prior to a full randomised controlled trial evaluation.

Future work

Optimisation of the intervention, and clearer specification of recipients, are required prior to a full trial evaluation.

Concurrent validity and reliability of an activity monitoring for rehabilitation (AMoR) platform for step counting and sitting/lying time in post-stroke individuals

BACKGROUND

Objective and reliable measurements to investigate daily behavior patterns in people with stroke could help therapeutic interventions after a stroke.

OBJECTIVE

To evaluate whether the Activity Monitoring for Rehabilitation (AMoR) platform has adequate concurrent validity and reliability for step counting and time spent sitting/lying in people post-stroke and to investigate its percentage accuracy for step counting at different walking speeds.

METHODS

Cross-sectional observational study. Fifty chronic post-stroke subjects used the AMoR platform and SAM simultaneously while a Video camera recorded the same activities during clinical trials. Spearman's correlation coefficient, the mean absolute percentage error, the intraclass correlation coefficient and Bland-Altman plot analyses were used to estimate the validity and reliability of the AMoR platform and StepWatch^TM Activity Monitor (SAM). The accuracy percentage was calculated for each device and plotted as a function of the walking speed during the 10-meter walk test (10MWT).

RESULTS

There was a very high correlation for step counting in all tests and a high correlation for time spent sitting/lying. The mean absolute percentage error values remained below 4% for step counting and time sitting/lying. The AMoR platform also showed excellent reliability for step counting and sitting/lying time, with values within the limit of agreement in the Bland-Altman plots. A high percentage of accuracy for step counting in the AMoR platform was observed during the 10MWT.

CONCLUSION

The AMoR platform is valid and reliable for step counting and time spent sitting/lying, with a high percentage of accuracy at different walking speeds in the post-stroke population.

Physical activity and sedentary behaviour in secondary prevention of coronary artery disease: A review

Comprehensive management of coronary artery disease (CAD) includes physical exercise as a part of daily lifestyle therapy. Still CAD patients generally have low physical activity (PA) and high sedentary behaviour (SB). This review summarizes the effect of exercise training and habitual PA and SB on physical fitness and quality of life (QoL) as well as on rehospitalizations and mortality in patients with stable CAD, recent acute coronary syndrome (ACS) or recent revascularization. A literature review of the influence of exercise, and PA and SB profiles in secondary prevention of CAD was performed using PubMed. All articles published between January 2001 and April 2019, meeting the inclusion criteria were considered. A total of 25 cross-sectional or prospective studies or randomized controlled trials (RCT) were included to this review. Exercise training was found to improve maximal oxygen consumption, QoL, and to reduce rehospitalizations and mortality among patients with established CAD. Remote PA interventions have not been as effective as the supervised exercise sessions in reducing the clinical endpoints. High SB, especially when combined to low PA, is associated with poor cardiorespiratory fitness and worse long-term prognosis among patients with ACS. In conclusion, exercise training and high PA are beneficial for patients with stable CAD, recent ACS or recent revascularization. High SB is associated with poor cardiopulmonary fitness and increased mortality in ACS patients. Novel tools using online applications and smart devices are promising means to offer remote guidance for PA among patients unable to participate in regular exercise sessions.

"Factors influencing sedentary time and physical activity early after stroke: a qualitative study"

PURPOSE

We aimed to understand from the perspective of stroke survivors and their carers (1) factors contributing to sedentary time and physical activity during inpatient rehabilitation and the transition home, and (2) actual and perceived opportunities to reduce sedentary time and increase physical activity.

MATERIAL AND METHODS

Qualitative study with 7 stroke survivor/carer dyads and 8 stroke survivors. Semi-structured interviews were conducted 2-4 weeks after hospital discharge, audio recorded and transcribed prior to thematic analysis.

RESULTS

Stroke survivors were mean age 69 [SD15] years (53% male). Carers were mean age 62 [SD15] years (86% were female). Five themes were identified: (1) Education and guidance about physical activity and sedentary behaviour after stroke is important to build understanding of recovery and secondary prevention, (2) Stroke survivors need clear communication about safety and risk, (3) Return to life participation supports motivation for and engagement in physical activity, 4) Social and professional influences and 5) Opportunities to be physically active.

CONCLUSION

Stroke survivors and their carers need a clearer understanding of the role of physical activity and risks of sedentary time during stroke recovery. Physical activity enablers included consistent communication, building confidence and skills to self-manage activity before discharge.Implications for RehabilitationInpatient rehabilitation and early after discharge may be an important time-point to support stroke survivors to establish long term physical activity behaviours before contact with healthcare professionals reduces.To reduce sedentary behaviour, people need to understand the health benefits of breaking up sedentary time and people who need physical support to stand up will need greater support from health professionals.Being able to imagine a future post-stroke self is important motivation to get up and move. Rehabilitation should help develop a person's vision of their post-stroke self.Managing potential risks in hospital without overly restricting physical activity is important and requires consistent communication from the multi-disciplinary team.Building a person's confidence and skills to self-manage physical activity in the community prior to discharge home may be another key enabler for activity.

Noninvasive Intracranial Pressure Monitoring in Chronic Stroke Patients with Sedentary Behavior: A Pilot Study

OBJECTIVE

This study aimed to correlate the P2/P1 ratio of intracranial pressure waveforms with sedentary behavior during the chronic stage of stroke.

MATERIALS AND METHODS

Eight patients from São Carlos, Brazil, who had hemiparesis and stroke onset within the previous 6 months, participated in this study. To monitor their intracranial pressure, we used noninvasive Brain4Care^® intracranial pressure monitoring during a postural change maneuver involving 15 min in a supine position and 15 min in an orthostatic position. The patients' sedentary behavior was continually monitored at home using a StepWatch Activity Monitor™ for 1 week. Moreover, the patients completed the International Physical Activity Questionnaire before and after using the StepWatch Activity Monitor™.

RESULTS

In the supine and orthostatic positions, the P2/P1 ratios were 0.84 ± 0.14 and 0.98 ± 0.17, respectively. The percentage of time spent in inactivity was 71 ± 11%, and the number of steps walked per day was 4220 ± 2239. We found a high positive correlation (r = 0.881, p = 0.004) between the P2/P1 ratio and the percentage of time spent in inactivity.

CONCLUSION

This preliminary study showed a correlation between sedentary behavior and cerebral compliance. Thus, monitoring of intracranial pressure during the late stage of a stroke could guide the clinician's treatment to reduce sedentary behavior and the risks of recurrent stroke and cardiovascular diseases.

Adherence to physical activity and cardiovascular recommendations during the 2years after stroke rehabilitation discharge

BACKGROUND

Objective measurement is essential to represent habitual physical activity. To date only one study has objectively measured physical activity for>12months after stroke.

OBJECTIVES

This study aimed to measure physical activity, cardiovascular risk factors, mobility, mood, fatigue and cognition during the 2years after rehabilitation discharge and to investigate whether stroke survivors meet physical activity and cardiovascular risk recommendations.

METHODS

This was a longitudinal observational study. Survivors of a first-ever stroke admitted to a large metropolitan rehabilitation hospital were recruited. Outcomes were measured at rehabilitation discharge and 6, 12 and 24months later. Outcomes were physical activity measured by the SenseWear Armband (e.g., moderate-vigorous physical activity, steps/day) and cardiovascular risk factors (e.g., blood pressure, fasting lipid profile and plasma glucose, waist circumference, body mass index), mobility, mood, fatigue and cognition. Changes over time were evaluated with random-effects regression modelling.

RESULTS

Participants (n=79, 33% female) had mean (SD) age of 65 (14) years and median gait speed 1.2m/s (interquartile range: 0.8-1.4) at baseline. We found no change in physical activity levels over time. Step count and time spent in bouts of moderate-vigorous physical activity remained low. Many participants achieved the recommended 30min of daily moderate-vigorous physical activity at baseline, but this was decreased at 2years (72% [57/79] versus 65% [37/57]). Adherence to cardiovascular recommendations decreased over time, notably for body mass index, plasma glucose and triglyceride levels. Waist circumference and body mass index increased at each time point relative to baseline (by a mean of 3.2cm and 1.2kg.m², respectively, at 2years, P<0.01).

CONCLUSIONS

This is the largest longitudinal study of objectively measured physical activity after stroke. Adherence to cardiovascular risk recommendations decreased over time post-stroke, and physical activity levels remained low. Stroke survivors may benefit from annual multidisciplinary reviews to identify increasing risk and initiate appropriate interventions.

Is long-bout sedentary behaviour associated with long-term glucose levels 3 months after acute ischaemic stroke? A prospective observational cohort study

BACKGROUND AND PURPOSE

Sedentary behaviour is a risk factor for vascular disease and stroke patients are more sedentary than their age-matched peers. The association with glucose levels, as a potential mediator, is unclear, and we have investigated the association between long-bout sedentary behaviour and long-term glucose levels in stroke survivors.

METHODS

This study uses data from the Norwegian Cognitive Impairment After Stroke study, a multicentre cohort study. The patients were recruited at hospital admission for acute stroke, and the follow-up was done at the outpatient clinic. Sedentary behaviour-being in a sitting or reclining position-was registered 3 months after stroke using position transition data from the body-worn sensor activPAL attached to the unaffected thigh. A MATLAB script was developed to extract activity data from 08:00 to 10:00 for 4 days and to categorise the data into four bout-length categories. The primary outcome was glycated haemoglobin (HbA1c), analysed at 3 months. Regression models were used to analyse the association between HbA1c and sedentary behaviour in the whole population and stratified based on a diagnosis of diabetes mellitus (DM). Age, body mass index and the use of antidiabetic drugs were added as covariates into the models.

RESULTS

From a total of 815 included patients, 379 patients fulfilled the inclusion criteria for this study. We found no association between time in sedentary behaviour and HbA1c in the whole stroke population. We found time in sedentary behaviour in bouts of ≥90 min to be associated with a higher HbA1c in patients with DM.

CONCLUSION

Long-bout sedentary time is associated with a higher HbA1c in patients with DM 3 months after ischaemic stroke. Future research should investigate the benefit of breaking up sedentary time as a secondary preventive measure.

Telerehabilitation After Stroke Using Readily Available Technology: A Randomized Controlled Trial

Background

The number of people living with stroke has increased demand for rehabilitation. A potential solution is telerehabilitation for health care delivery to promote self-management. One such approach is the Augmented Community Telerehabilitation Intervention (ACTIV). This structured 6-month program uses limited face-to-face sessions, telephone contact, and text messages to augment stroke rehabilitation.

Objective

To investigate whether ACTIV improved physical function compared with usual care.

Methods

This 2-arm, parallel randomized controlled trial was conducted in 4 New Zealand centers. Inclusion criteria were patients with first-ever stroke, age >20 years, and discharged home. A blinded assessor completed outcome measurement in participants’ homes at baseline, postintervention, and 6 months postintervention. Stratified block randomization occurred after baseline assessment, with participants allocated to ACTIV or usual care control.

Results

A total of 95 people were recruited (ACTIV: n = 47; control: n = 48). Postintervention intention-to-treat analysis found a nonsignificant difference between the groups in scores (4·51; P = .07) for physical function (measured by the physical subcomponent of the Stroke Impact Scale). The planned per-protocol analysis (ACTIV: n = 43; control: n = 48) found a significant difference in physical function between the groups (5·28; P = .04). Improvements in physical function were not maintained at the 12-month follow-up.

Conclusions

ACTIV was not effective in improving physical function in the ACTIV group compared with the usual care group. The per-protocol analysis raises the possibility that for those who receive more than 50% of the intervention, ACTIV may be effective in preventing deterioration or even improving physical function in people with stroke, in the period immediately following discharge from hospital.

Sedentary behavior patterns over 6 weeks among ambulatory people with stroke

Objective: To describe patterns of sedentary behavior over 6 weeks among ambulatory people with subacute and chronic stroke.Design: Observational longitudinal study with assessments at baseline (T0) and week 6 (T1).Methods: Community-dwelling people with stroke (n = 39) pooled from two studies who were ≥18 years of age were assessed for sedentary behavior at 2 timepoints (T0, T1). Sedentary behavior was measured with the activPAL micro3 following a 7-day wear protocol to obtain mean daily: total sitting time, sitting time accumulated in bouts ≥30 minutes, number of sit-to-stand transitions, and fragmentation index (sit-to-stand transitions/total sitting hours). Paired samples t-tests were used to calculate mean group differences in sedentary behavior metrics between T0 and T1 (α =.05). Cohen's d was calculated to describe the magnitude of within-person change between T0 and T1.Results: There were no statistically significant within-person differences between T0 and T1 on mean daily sitting time (Cohen's d= -0.21, p=.19), sitting time accumulated in bouts ≥30 minutes (d= -0.27, p=.11), number of sit-to-stand transitions (d= -0.02, p=.53), or the fragmentation index (d= -0.11, p=.92).Conclusions: Sedentary behavior metrics were stable for over 6 weeks. The number of sit-to-stand transitions per day and the fragmentation index appeared to be the most stable indicators over 6 weeks. Future research should confirm these findings and identify correlates of sedentary behavior among people with stroke.

Subgrouping patients with chronic low back pain: What are the differences in actual daily life behavior between patients classified as avoider or persister?

BACKGROUND AND OBJECTIVE

The purpose of this study is to determine whether patients, classified by their treating consultant in rehabilitation medicine as avoider or persister, show differences in a large set of detailed outcomes of actual, objectively measured daily physical behaviour.

METHODS

In this explorative cross-sectional study, 16 patients were included; 9 patients were categorized as avoider and 7 patients as persister. Subjects wore the VitaMove activity monitor, a high-end accelerometry-based device that allowed automatic detection of a large set of body postures and motions. Physical behaviour was assessed in detail by total duration of body postures and motions as percentages of 24 hours, as well as by the number of sit-to-stand transfers, overall activity level, walking speed, and the distribution of bouts of physical activity and sedentary behaviour. Differences between groups were tested with the Mann Whitney U test.

RESULTS

There were no significant differences between groups in any of the physical behaviour outcomes.

CONCLUSIONS

Our study showed that activity-related behavioural style categorization by consultants in rehabilitation medicine is not expressed in objectively measured detailed outcomes of daily physical behaviour.

Factors related to post-stroke depression during the first 2 weeks after stroke

Introduction

This study aimed to clarify factors associated with post-stroke depression in patients with acute stroke within 2 weeks of onset.

Method

Eighty-eight patients with stroke were divided into post-stroke depression ( n = 49) and non-post-stroke depression ( n = 39) groups based on their Hamilton Depression Rating Scale scores. We evaluated stroke severity, upper limb function, activities of daily living, frontal lobe/cognitive function, and level of apathy. Activity levels were measured using an ActiGraph GT9X Link system. Mann–Whitney U-tests were used to determine differences between the two groups. Spearman’s rank correlation and logistic regression analyses were also performed.

Results

The post-stroke depression and non-post-stroke depression groups exhibited significant differences in National Institutes of Health Stroke Scale scores at admission and discharge; Functional Independence Measure exercise items, cognitive items, and total items at admission; Fugl-Meyer Assessment scores; and Apathy Rating Scale scores. Logistic regression indicated that Fugl-Meyer Assessment scores were associated with post-stroke depression.

Conclusion

Stroke severity, paralysis, and physical function/activities of daily living ability are associated with post-stroke depression in the acute phase. Our findings suggest that increases in physical impairment severity are associated with increased post-stroke depression risks. Rehabilitation professionals should focus on identifying post-stroke depression in early post-stroke stages.
