Systematic framework to classify the status of research on spinal cord injury and physical activity

Sedentary Behavioral Studies of Young and Middle-Aged Adults with Hypertension in the Framework of Behavioral Epidemiology: A Scoping Review

(1) Background: As times change, the detection rate of hypertension is increasing in the young and middle-aged population due to prevalent sedentary behaviors. The purpose of this study was to conduct a scoping review to identify and summarize the research on sedentary behavior in this population by separating it into five stages: the relationship between sedentary behavior and health; measurement modalities; influencing factors; interventions; and translational research in young and middle-aged adults with hypertension. (2) Methods: Using a scoping review research approach, the PubMed, Web of Science Core Collection, and MEDLINE databases were used to search for the literature on this subject from the date of the database's creation to 14 June 2022, and the behavioral epidemiology framework was used to classify the retrieved articles. (3) Results: A total of eight articles were included. Among them, there were six articles on the relationship between behavior and health, which includes blood pressure, insulin resistance, and the cardiovascular system; one article on the study of measurement methods, which was used for clinical decision making through decision trees; one article on influencing factors, which was divided into intrinsic and extrinsic factors; and no articles on intervention program development or the translation of intervention programs to further practice in this population. (4) Conclusions: Sedentary behavioral studies of young and middle-aged adults with hypertension are scarce and are generally carried out in the early stages of the condition. In the future, in-depth studies can be conducted on the dose-response relationship between sedentary behavior and health in this population; the development of easier and targeted measurement tools; the exploration of more influencing factors; and the effectiveness and translation of intervention programs.

Qualitative analysis of perceived motivators and barriers to exercise in individuals with spinal cord injury enrolled in an exercise study

STUDY DESIGN

Cross-sectional.

OBJECTIVES

Examine exercise perceptions of SCI individuals enrolled in an exercise trial about their: (a) reasons for enrolling, (b) barriers to exercise, and (c) solutions to address barriers.

SETTING

World-wide web.

METHODS

US individuals ≥18 years old with SCI completed password-protected free-response surveys (n = 144) as part of a larger internet-based intervention to promote exercise. Participants' online reporting about their motivations to exercise, barriers, and solutions to identified barriers were analyzed using an inductive thematic qualitative approach. Participants could enter up to 10 responses for each category.

RESULTS

Study staff analyzed 956 participant responses across questions regarding their motivations, barriers, and solutions. Leading reasons reported for enrolling were to improve their physical health (69%), function (61%), and attitude (59%) while commonly reported barriers were time constraints (54%), lack of motivation (31%), accessibility issues (24%), and SCI-specific barriers (23%). Participant-generated solutions were scheduling exercise (47.9%) for time constraints, making exercise more fun (21.8%) to increase motivation, obtaining home exercise equipment (30.3%), and locating accessible facilities (27.3%) to resolve accessibility barriers. Solutions for SCI-specific barriers of temperature control, skin breakdown, and pain included getting adapted equipment or finding exercises they could perform independently (29.3%) and enlisting support from friends or family (24.4%).

CONCLUSIONS

The results offer insights about exercise motivators and barriers reported by people with SCI who enrolled in an exercise intervention program and offer insights regarding topics to address for SCI-tailored exercise programs. Further research should examine what strategies are most useful in helping people with SCI engage in exercise.

Hybrid high-intensity interval training using functional electrical stimulation leg cycling and arm ski ergometer for people with spinal cord injuries: a feasibility study

Aim

The aim was to assess safety and feasibility of Hybrid High-Intensity Interval Training (HIIT) using Functional Electrical Stimulation (FES) leg cycling and arm ski ergometer in people with Spinal Cord Injuries (SCI).

Method

Eight outpatients (mean age 42.8 years; 7 men) with stable SCI paraplegia (mean 14.5 years since injury) participated in hybrid HIIT (90% peak watts; 4 × 4–min intervals), three times a week (over 8 weeks). Primary outcomes were Adverse Events (AE), participant acceptability, shoulder pain, training intensity (% peak watts), and attendance.

Secondary outcomes were effect on peak oxygen uptake (VO₂peak) during FES hybrid poling, mean watts, self-reported leisure time physical activity, quality of life, and fatigue.

Results

No serious AE occurred; acceptability with the training modality was high, while shoulder pain increased by 9% (SD 95.2). During training, 50% of the participants reached > 90% peak watts during the intervals, three with the legs (FES cycle) and one with the arms (Ski-Erg). Overall, mean training intensity (% peak watts) was 92% (SD 18.9) for legs and 82% (SD 10.3) for arms. Proportion of fulfilled training minutes was 82% (range 36–100%); one participant dropped out after 6 weeks due to back pain. Mean VO₂peak increased by 17% (SD 17.5). Participants reported increased leisure time physical activity and health-related quality of life, besides reduced fatigue.

Conclusion

Hybrid HIIT was safe for people with SCI paraplegia. The majority of the criteria for feasibility were met with acceptable attendance rate, limited drop out, participants enjoyed training, and increased VO₂peak and mean watts. However, the intensity of 90% peak watts was reached by < 60% of the participants despite high RPE ratings during training. The method of measuring and calculating intensity needs to be studied further before a study using this HIIT protocol is undertaken.

Feasibility of an Internet-Based Intervention to Promote Exercise for People With Spinal Cord Injury: Observational Pilot Study

BACKGROUND

People with spinal cord injury (SCI) are less likely to be physically active and have higher chronic disease risk than those in the general population due to physical and metabolic changes that occur postinjury. Few studies have investigated approaches to promote increased physical activity (PA) for people with SCI despite evidence that they face unique barriers, including lack of accessible transportation and exercise equipment. To address these obstacles, we adapted an evidence-based phone-delivered intervention that promoted increased PA among people with SCI into a web-based platform, titled the Workout on Wheels internet intervention (WOWii). The adapted program provides participants with weekly skill-building information and activities, basic exercise equipment, and ongoing support through weekly group videoconferencing.

OBJECTIVE

This pilot study was conducted to assess the feasibility of using a web-based and virtual format to deliver the WOWii program in a randomized controlled trial.

METHODS

We assessed the feasibility of the web-based program by delivering an abbreviated, 4-week version to 10 participants with SCI. Rates of weekly videoconference attendance, activity completion, and exercise activity as tracked by an arm-based activity monitor were recorded for all participants.

RESULTS

Participants averaged 3.3 of 4 (83%) weekly group videoconferences attended, 3.4 of 4 (85%) web-based module activities completed, and 2.3 of 4 (58%) weeks of using the arm-based activity monitor. The majority of the sample (9/10, 90%) synced their arm-based PA monitor at least once, and overall engagement as an average of each component across the 4 weeks was 75%.

CONCLUSIONS

The intervention had sufficiently high levels of engagement to be used in a full randomized controlled trial to test its effectiveness in improving levels of PA among people with SCI. The knowledge we gained from this pilot study informed improvements that were made in the full randomized controlled trial.

Novel stochastic framework for automatic segmentation of human thigh MRI volumes and its applications in spinal cord injured individuals

Severe spinal cord injury (SCI) leads to skeletal muscle atrophy and adipose tissue infiltration in the skeletal muscle, which can result in compromised muscle mechanical output and lead to health-related complications. In this study, we developed a novel automatic 3-D approach for volumetric segmentation and quantitative assessment of thigh Magnetic Resonance Imaging (MRI) volumes in individuals with chronic SCI as well as non-disabled individuals. In this framework, subcutaneous adipose tissue, inter-muscular adipose tissue and total muscle tissue are segmented using linear combination of discrete Gaussians algorithm. Also, three thigh muscle groups were segmented utilizing the proposed 3-D Joint Markov Gibbs Random Field model that integrates first order appearance model, spatial information, and shape model to localize the muscle groups. The accuracy of the automatic segmentation method was tested both on SCI (N = 16) and on non-disabled (N = 14) individuals, showing an overall 0.93±0.06 accuracy for adipose tissue and muscle compartments segmentation based on Dice Similarity Coefficient. The proposed framework for muscle compartment segmentation showed an overall higher accuracy compared to ANTs and STAPLE, two previously validated atlas-based segmentation methods. Also, the framework proposed in this study showed similar Dice accuracy and better Hausdorff distance measure to that obtained using DeepMedic Convolutional Neural Network structure, a well-known deep learning network for 3-D medical image segmentation. The automatic segmentation method proposed in this study can provide fast and accurate quantification of adipose and muscle tissues, which have important health and functional implications in the SCI population.

A scoping review on interventions to promote physical activity among adults with disabilities

BACKGROUND

Despite the strong evidence that physical activity (PA) is a key determinant of health, there is limited knowledge on the content and outcomes of PA promotion interventions among individuals with disabilities.

OBJECTIVE

To conduct a scoping review in order to examine the published literature on PA promotion interventions among adults with disabilities.

METHODS

A scoping review following the methodological framework provided by Arksey and O'Malley used electronic databases (MEDLINE, PsycINFO, and CINAHL), reference lists, and journals to locate studies. Inclusion criteria were based on study aim, outcome measures, and a disability definition by the WHO International Classification of Functioning, Disability and Health. The Behavior Change Techniques Taxonomy version 1 and Furlan and collaborators' risk of bias assessment were utilized during the data charting stage.

RESULTS

Thirty-eight articles met the inclusion criteria. Most of the studies (70%) reported a significant increase in PA behavior immediately following intervention. However, less than half of the studies (46%) examined the maintenance of pre-/post-test differences. The number of identified behavior change techniques was significantly higher for successful PA promotion interventions than for interventions with no effects on PA. Approximately one-third of studies (32%) were rated as having a high risk of bias.

CONCLUSIONS

Although findings support the idea that PA promotion interventions produce positive changes in PA behavior for a variety of disability conditions, risk of bias assessment calls for prudence. There are opportunities for continued development of the area of PA promotion among individuals with disabilities through systematic reviews and meta-analyses.

Reducing barriers to healthy weight: Planned and responsive adaptations to a lifestyle intervention to serve people with impaired mobility

BACKGROUND

People with impaired mobility (IM) disabilities have a higher prevalence of obesity and obesity-related chronic conditions; however, lifestyle interventions that address the unique needs of people with IM are lacking.

OBJECTIVE

This paper describes an adapted evidence-based lifestyle intervention developed through community-based participatory research (CBPR).

METHODS

Individuals with IM, health professionals, disability group representatives, and researchers formed an advisory board to guide the process of thoroughly adapting the Diabetes Prevention Program Group Lifestyle Balance (DPP GLB) intervention after a successful pilot in people with IM. The process involved two phases: 1) planned adaptations to DPP GLB content and delivery, and 2) responsive adaptations to address issues that emerged during intervention delivery.

RESULTS

Planned adaptations included combining in-person sessions with conference calls, providing arm-based activity trackers, and adding content on adaptive cooking, adaptive physical activity, injury prevention, unique health considerations, self-advocacy, and caregiver support. During the intervention, participants encountered numerous barriers, including health and mental health issues, transportation, caregivers, employment, adjusting to disability, and functional limitations. We addressed barriers with responsive adaptations, such as supporting electronic self-monitoring, offering make up sessions, and adding content and activities on goal setting, problem solving, planning, peer support, reflection, and motivation.

CONCLUSIONS

Given the lack of evidence on lifestyle change in people with disabilities, it is critical to involve the community in intervention planning and respond to real-time barriers as participants engage in change. A randomized controlled trial (RCT) is underway to examine the usability, feasibility, and preliminary effectiveness of the adapted intervention.

Physical Activity Research in Intellectual Disability: A Scoping Review Using the Behavioral Epidemiological Framework

Through a scoping review, the current state of physical activity research in people with intellectual disability was examined. A search of publications between 2000 and 2014 retrieved 362 articles that met inclusion criteria. Eligible studies were coded according to the Behavioral Epidemiological Framework. Of the articles identified, 48% examined associations between physical activity and health outcomes, 9% developed or tested methodology to measure physical activity, 34% examined factors that influence physical activity, 8% evaluated interventions to change physical activity, and 1% examined the dissemination of physical activity/health promotion programming. The categories with lower proportions of studies represent the need for greater population-specific research in physical activity measurement, interventional designs, and translational programs.

Health status of regularly physically active persons with spinal cord injury

Study design

A non-controlled cross-sectional study.

Objectives

To make a descriptive examination of health status in persons with paraplegia and tetraplegia who exercise regularly according to Canadian guidelines.

Settings

Sunnaas Rehabilitation Hospital and the Norwegian School of Sport Sciences.

Methods

Eighteen persons (men/women = 9/9), aged 41‒72 years with spinal cord injury (SCI), who exercise regularly were included. Post-injury years ranged from 4 to 48 years. Clinical examination of body composition, bone mineral density (BMD), forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), diffusion capacity (DL_CO), cardiorespiratory fitness (VO_2max), and self-reported quality of life (QOL) obtained by questionnaire was performed. Lung function results are presented as % predicted and VO_2max as absolute values relative to body weight. All results are given as median and range.

Results

Persons with paraplegia (n = 13) were defined as overweight with fat mass 42% (25‒51). BMD 1.047 g cm⁻² (0.885‒1.312) was within normal range. FVC 95% predicted (60‒131), FEV₁ 90% predicted (61‒119), DL_CO 77% predicted (56‒103), and VO_2max 16.66 ml kg⁻¹ min⁻¹ (12.15‒25.28) defined good aerobic capacity according to age controlled reference values (18). Persons with tetraplegia (n = 5) were slightly overweight with fat mass 35% (26‒47). BMD 1.122 g cm⁻² (1.095‒1.299) was within normal range. FVC 72% predicted (46‒91), FEV₁ 75% predicted (43‒83), DL_CO 67% predicted (56‒84), and VO_2max 16.70 ml kg⁻¹ min⁻¹ (9.91‒21.01) defined excellent aerobic capacity according to reference values (18). QOL was ranked as median 7.5 (0‒10 scale).

Conclusions

Persons with SCI who exercise regularly following the Canadian guidelines responded with rather positive associations for health outcomes. Additional research is needed to strengthen our findings.

A Telerehabilitation Approach to Enhance Quality of Life Through Exercise Among Adults With Paraplegia: Study Protocol

Background

Despite compelling evidence linking physical activity and quality of life among adults with spinal cord injury (SCI), exercise participation rates are extremely low in this population. Unfortunately, a lack of behavioral exercise interventions, in particular theory-based randomized controlled trials (RCT), exists within the SCI literature. A pilot RCT is needed to first examine the feasibility to conduct such interventions and determine the appropriate effect size to inform future full-scale interventions.

Objective

The overall goal of this pilot RCT is to test an 8-week innovative, video-based telerehabilitation intervention based on self-determination theory and aimed at enhancing the basic psychological needs, motivation, exercise participation, and quality of life‒related outcomes of adults with paraplegia. The objectives are to (1) determine if individuals in the intervention group have greater increases in their basic psychological needs and autonomous motivation and a decrease in controlled motivation compared to the control group, (2) determine whether the intervention group reports greater increases in exercise participation and quality of life‒related variables (eg, life satisfaction, participation in daily/social activities, depressive symptoms) compared to the control group, and (3) examine if adults with paraplegia who received the intervention report improved scores on psychosocial predictors of exercise (eg, action planning) and well-being (eg, positive affect) compared to the control group. We also aimed to examine the implementation characteristics of the intervention (eg, satisfaction with the technology, counselor’s ability to foster the psychological needs).

Methods

Adults with paraplegia (N=24) living in the community will be recruited. All participants will be invited to complete assessments of their psychological needs, motivation, exercise, and quality of life‒related variables at three time points (baseline, 6, and 10 weeks). Following the baseline assessment, participants will be randomly assigned to the intervention or control group. Participants in the intervention group will participate in 8 weekly, 1-hour video-based telerehabilitation sessions with a trained physical activity counselor, while participants in the control group will be asked to continue with their regular routine.

Results

We expect higher ratings of the basic psychological needs and autonomous motivation and lower scores for controlled motivation for the intervention group compared to the control group (Objective 1). We also expect that our video-based intervention will have moderate effects on exercise participation, as well as small-to-moderate positive effects on the quality of life‒related variables (Objective 2). Finally, we expect the intervention to have a small positive effect on psychosocial predictors of physical activity and well-being (Objective 3).

Conclusions

We anticipate that the results will show that the intervention is appropriate for adults with paraplegia and feasible to test in a full-scale RCT.

Stakeholder evaluation of an online program to promote physical activity and workplace safety for individuals with disability

Individuals with disabilities face increasing health and employment disparities, including increased risk of morbidity and mortality and decreased earnings, occupational roles, and greater risk of injury at work. Thus, there is a need to improve workplace safety and health promotion efforts for people with disability. The purpose of this study was to obtain stakeholder feedback about an online program, Be Active, Work Safe, which was developed to increase the physical activity and workplace safety practices of individuals with disability. Eight stakeholders (content experts and individuals with disability) evaluated the 8-week online program and provided feedback on accessibility, usability, and content using quantitative and qualitative approaches. Stakeholders suggested changes to the organization, layout and accessibility, and content. This included making a stronger connection between the physical activity and workplace safety components of the program, broadening content to apply to individuals in different vocational fields, and reducing the number of participant assessments. Engaging stakeholders in the development of health promotion programs is critical to ensure the unique issues of the population are addressed and facilitate engagement in the program. Feedback provided by stakeholders improved the program and provided insight on barriers for adoption of the program.

Development and evaluation of a social cognitive theory-based instrument to assess correlations for physical activity among people with spinal cord injury

BACKGROUND

People with spinal cord injury (SCI) are more susceptible to sedentary lifestyles because of the displacement of physical functioning and the copious barriers. Benefits of physical activity for people with SCI include physical fitness, functional capacity, social integration and psychological well-being.

OBJECTIVE

The purpose of this study was to develop and test a social cognitive theory-based instrument aimed to predict physical activity among people with SCI.

METHODS

An instrument was developed through the utilization and modification of previous items from the literature, an expert panel review, and cognitive interviewing, and tested among a sample of the SCI population using a cross-sectional design. Statistical analysis included descriptives, correlations, multiple regression, and exploratory factor analysis.

RESULTS

The physical activity outcome variable was significantly and positively correlated with self-regulatory efficacy (r = 0.575), task self-efficacy (r = 0.491), self-regulation (r = 0.432), social support (r = 0.284), and outcome expectations (r = 0.247). Internal consistency for the constructs ranged from 0.82 to 0.96. Construct reliability values for the self-regulation (0.95), self-regulatory efficacy (0.96), task self-efficacy (0.94), social support (0.84), and outcome expectations (0.92) each exceeded the 0.70 a priori criteria.

CONCLUSIONS

The factor analysis was conducted to seek modifications of current instrument to improve validity and reliability. The data provided support for the convergent validity of the five-factor SCT model. This study provides direction for further development of a valid and reliable instrument for predicting physical activity among people with SCI.

Are adults with spinal cord injury meeting the spinal cord injury-specific physical activity guidelines? A look at a sample from a Canadian province

STUDY DESIGN

One cross-sectional study.

OBJECTIVES

To examine the extent to which a sample of adults with spinal cord injury (SCI) meet the SCI-specific physical activity guidelines and to identify potential demographic, injury and motivational characteristics related to participation.

SETTING

Quebec, Canada.

METHODS

A sample of 73 adults from the province of Quebec, Canada living with SCI completed the Leisure Time Physical Activity Questionnaire for People with Spinal Cord Injury to report their current frequency (sessions per week) and duration (minutes per session) in aerobic and resistance physical activity.

RESULTS

Results showed that 12% of participants in this sample met the guidelines and as many as 44% reported 0 min of physical activity. Only the participants' mode of mobility and autonomous motivation for physical activity emerged as a marginal correlate of the likelihood of meeting the physical activity guidelines.

CONCLUSION

Overall, physical activity participation rates among adults in this sample living with SCI remain quite low. Given the benefits of physical activity for adults with SCI, physical activity promotion efforts are needed.

Auditing the Physical Activity and Parkinson Disease Literature Using the Behavioral Epidemiologic Framework

Motor and nonmotor symptoms associated with Parkinson disease place individuals at greater risk of sedentary behaviors and comorbidities. Physical activity is one modifiable means of improving health and reducing the risk of morbidity. We applied a behavioral framework to classify existing research on physical activity and Parkinson disease to describe the current evolution and inform knowledge gaps in this area. Research placed in phase 1 establishes links between physical activity and health-related outcomes; phase 2 develops approaches to quantify physical activity behavior; phase 3 identifies factors associated with implementation of physical activity behaviors; phase 4 assesses the effectiveness of interventions to promote activity; and phase 5 disseminates evidence-based recommendations. Peer-reviewed literature was identified by searching PubMed, Google Scholar, and EBSCO-host. We initially identified 287 potential articles. After further review, we excluded 109 articles, leaving 178 included articles. Of these, 75.84% were categorized into phase 1 (n = 135), 10.11% in phase 2 (n = 18), 9.55% into phase 3 (n = 17), 3.37% into phase 4 (n = 6), and 1.12% into phase 5 (n = 2). By applying the behavioral framework to the physical activity literature for people with Parkinson disease, we suggest this area of research is nascent with more than 75% of the literature in phase 1.

Accessible weight loss: Adapting a lifestyle intervention for adults with impaired mobility

BACKGROUND

Despite disparities in obesity between those with and without disability, there is limited evidence to guide weight loss intervention in people with impaired mobility (IM), particularly those with severe impairments.

OBJECTIVE

Examine the usability, feasibility, and effectiveness of adapting an existing evidence-based weight loss program for people with IM.

METHODS

In this single-group pre-test post-test pilot study, 10 overweight or obese individuals with permanent IM (e.g. spinal cord injury, spina bifida, osteoarthritis) participated in a 20-week modification of the DPP Group Lifestyle Balance™ (DPP GLB) program, a group-based adaptation of the Diabetes Prevention Program (DPP). Fifteen conference calls encouraged reducing calorie and fat intake and increasing exercise through self-monitoring and problem solving. We defined feasibility as retention and engagement, usability as participants' program satisfaction ratings, and effectiveness as physiological and psychosocial change measured on three occasions over 20 weeks. Analytic methods included basic descriptive statistics (feasibility and usability) and repeated measures ANOVA (effectiveness).

RESULTS

The program retained 70% of participants. These individuals attended an average of 79.3% of conference calls and self-monitored more than half of the weeks. Participants rated the program highly, with mean overall scores of 6.3 ± 0.3 and 6.2 ± 0.6 out of 7 on helpfulness and satisfaction scales, respectively. Program completers experienced a significant mean weight loss of 8.86 ± 8.37 kg (p = 0.024), or 7.4% of their start weight, and significantly reduced their BMI.

CONCLUSIONS

An adapted version of the DPP GLB is a feasible, usable, and potentially effective intervention for promoting weight loss among persons with IM.

The influence of a home-based exercise intervention on human health indices in individuals with chronic spinal cord injury (HOMEX-SCI): study protocol for a randomised controlled trial

BACKGROUND

Spinal cord injury (SCI) creates a complex pathology that can lead to an increase in sedentary behaviours and deleterious changes in body composition. Consequently, individuals with SCI are at increased risk of developing cardiovascular disease and type-2 diabetes mellitus. While the role of physical activity on the reduction of chronic disease risk is well documented in non-disabled individuals the evidence is less conclusive for persons with SCI. The aim of this methodological paper is to outline the design of a study that will assess the role of a home-based exercise intervention on biomarkers of metabolic and cardiovascular health in persons with SCI: the HOMEX-SCI study.

METHODS/DESIGN

Eligible participants will be inactive (physical activity level ≤1.60) individuals, with a chronic (more than 1 year) spinal cord lesion between the second thoracic and the fifth lumbar vertebrae, and aged between 18 and 65 years. Following baseline laboratory testing and lifestyle monitoring, participants will be randomly allocated to a control (CON) group or a 6-week home-based exercise intervention (INT) group. The INT consists of 45 minutes of moderate-intensity (60-65 % peak oxygen uptake) arm-crank exercise four times per week. Participants assigned to the CON group will be asked to maintain their normal lifestyle. The main outcomes of this study (biomarkers of metabolic and cardiovascular health) are obtained from venous blood samples, collected in the fasted and postprandial state. Eight other measurement categories will be assessed: (1) body composition, (2) physical activity, (3) energy intake, (4) measures of health and wellbeing, (5) resting metabolic rate, heart rate and blood pressure, (6) aerobic capacity, (7) immune function, and (8) adipose tissue gene expression.

DISCUSSION

This study will explore the feasibility of home-based moderate-intensity exercise and ascertain its impact on metabolic and cardiovascular health in comparison to a lifestyle maintenance CON group. Findings from this study may help to inform new evidence-based physical activity guidelines and also help to elucidate the physiological mechanisms whereby exercise might exert beneficial effects in persons with chronic SCI. The results will also act as a scientific platform for further intervention studies in other diverse and at-risk populations.

Classifying physical activity research following stroke using the behavioral epidemiologic framework

BACKGROUND

Stroke is a significant public health issue in the USA and a need emerges to better understand how to reduce an individual's co-morbidity risk. Physical activity is one approach to improving the health of individuals and comprehensive literature supports increased activity as a means to reduce risk of morbidity and mortality. One approach to examining whether research in a field is addressing a public health issue is through application of the behavioral epidemiological framework.

OBJECTIVE

To classify physical activity research for individuals following stroke into distinct phases so that efforts can be made to systematically address gaps and disseminate evidence-based practice.

METHODS

Specific key words were identified and then searched through EBSCO host, PubMed, and Google Scholar. Physical activity and stroke literature from 2000-2014 was categorized into one of five discrete phases. Research in Phase 1 identified associations between activity and health; Phase 2 established valid measures of activity; Phase 3 examined determinants of behavior; Phase 4 evaluated activity interventions; and Phase 5 disseminated evidence-based practice.

RESULTS

A comprehensive review of literature identified 202 articles with 70% categorized in Phase 1 (n = 141), 11% in Phase 2 (n = 23), 10% in Phase 3 (n = 20), 8% in Phase 4 (n = 15), and 1% in Phase 5 (n = 3).

CONCLUSION

Findings suggest that physical activity research for individuals following stroke is in the early stages of development with less than 10% of research evaluating or disseminating interventions.
