Piloting the effectiveness of the Workout on Wheels Internet Intervention (WOWii) program among individuals with mobility disabilities

BACKGROUND

Doing any amount of moderate-to-vigorous physical activity yields health benefits. Individuals with mobility disabilities are among the least physically active Americans and limited evidence indicates effective strategies to promote physical activity among this group.

OBJECTIVE

Examine whether a 16-week virtual intervention program (Workout on Wheels internet intervention, WOWii) increases exercise engagement among mobility impaired individuals.

METHODS

Participants recruited through community organizations that provide services to individuals with disabilities. The WOWii program is comprised of 3 core components: 16 weeks of virtual intervention delivery and access to the WOWii website; staff and peer support; an exercise package that included an activity tracker and heart rate monitor, pedal exerciser, and therabands.

RESULTS

Ten people enrolled. Participants demonstrated good program engagement, attending an average of 14.1 ± 2.1 of the 16 virtual meetings and completing an average of 10.6 ± 5.6 weekly activities. Exercise data revealed that participants increased their time spent in aerobic exercise from an average of two days a week performing 32 ± 22 min during week one to an average of five days a week doing 127 ± 143 min in the final WOWii week. Only half continued to exercise over the two months once WOWii virtual meetings ended.

CONCLUSIONS

WOWii program delivery successfully promoted increased exercise participation for people with mobility disabilities over the 16 intervention weeks. Future studies should investigate approaches to promote exercise maintenance beyond program delivery.

Feasibility, acceptability, and initial efficacy of a wheelchair exercise training program in persons with multiple sclerosis: study protocol for a parallel group randomized controlled trial

Purpose: This study is a randomized controlled trial (RCT) that examines the feasibility, acceptability, and initial efficacy of a home-based, remotely supported and supervised exercise training program that was developed using a three-step community engaged research process for persons with multiple sclerosis (MS) who are wheelchair users.Materials and Methods: The study design is a parallel group RCT (NCT05888727). We aim to enroll 24 wheelchair users with MS who will be randomly assigned using REDCap randomization module into exercise training or attention/contact wellness control conditions. The conditions will be delivered remotely over 16 weeks and supported using online, one-onone behavioral coaching. The feasibility outcomes of interest include recruitment and retention rates, and safety outcomes collected throughout the study period. The acceptability outcomes include participant satisfaction and perceptions measured using formative surveys and interviews following the 16-week period. Efficacy outcomes include metabolic health, MS symptoms, and exercise behavior measured before and after the 16-week period. The data analysis will follow intent-to-treat principles using 2 group by 2 time mixed factor ANOVA with estimation of Cohen's d values as effect sizes.Conclusions: The results will guide future research targeting health outcomes using exercise training among wheelchair users with MS who have largely been absent from health promotion research.

Developing a community-engaged wheelchair exercise program for persons with MS: community advisory board formation and feedback

PURPOSE

Exercise is a safe, evidence-based approach for improving symptoms such as mobility impairment, cognitive dysfunction, and fatigue; however, persons with multiple sclerosis (MS) who use wheelchairs for mobility have been excluded from most research. This paper describes our approach for recruiting ten community advisor board (CAB) members and partnering with them on developing a novel home-based exercise training program for wheelchair users with MS.

MATERIALS AND METHODS

The exercise training program, which was developed based on initial qualitative research, includes a progressive exercise prescription, equipment, and one-on-one behavioural coaching based on Social Cognitive Theory. The CAB members convened in groups of five people for five meetings online, using virtual conference software. The CAB meetings each lasted approximately 1-hour and notes were transcribed into digital format for data analyses.

RESULTS

Content analysis identified elements that aligned with meeting foci (i.e., prescription, equipment, coaching, and outcomes). Feedback was divided into categories to refine the program, specifically modifying, adding, or retaining content and/or activities. CAB member feedback was very positive and emphasised potential additions to the materials presented. The research team proposed implementing modifications based on the CAB member feedback such as adding wrist weights to the equipment options for completing resistance training exercises.

CONCLUSIONS

The overall CAB feedback was invaluable for assessing the appropriateness of the proposed exercise training program before initiating feasibility testing. This report provides a model and guidance for researchers who seek community-engaged research approaches in creating products and interventions.Implication for RehabilitationCommunity advisory board participation was invaluable in creating and modifying a novel exercise training programmes for wheelchair users with multiple sclerosis (MS).The current study provides a framework for the creation of exercise interventions for subpopulations of persons with MS that may provide substantial rehabilitation benefits such as improved symptoms and quality of life.Health behaviour interventists targeting individuals with disabilities may consider the benefits of recruiting stakeholders from the community in creation of novel programmes.

Baseline health-related self-efficacy for individuals following stroke, traumatic brain injury, and spinal cord injury prior to enrollment in a weight-loss intervention

PURPOSE

To examine health-related self-efficacy for individuals following acquired brain or spinal cord injury prior to enrollment in a weight-loss intervention and associations with demographics, injury characteristics, and additional physiologic variables.

MATERIALS AND METHODS

Cross-sectional analysis of baseline data for community-dwelling adults following stroke (CVA), traumatic brain injury (TBI), or spinal cord injury (SCI) across three disability-adapted weight-loss interventions.

RESULTS

Overall results suggest a significant difference between injury type and self-efficacy as measured by the Self Rated Abilities for Health Practices (SRAHP) scale. On average, individuals with SCI had the lowest overall perceived self-efficacy of the three groups (11.2-unit difference; (CI: -17.4, -5.0), followed by those with TBI (9.5-unit difference; (CI: -16.7, -2.4). There were also differences between groups in age, number of household members, time since injury, sex, race, marital status, physiological measures, and employment status.

CONCLUSIONS

Results suggest that individuals with different disabilities following neurological injuries have different baseline perceptions in their ability to eat a healthy diet and exercise regularly. Health interventions should be tailored for these groups based on disability-specific barriers and should include components to enhance health-related self-efficacy to address weight management among these populations.IMPLICATIONS FOR REHABILITATIONEvidence suggests that health-related self-efficacy may differ following different injury types and level of disability may impact one's ability to maintain health-related behaviorsResults suggest that individuals with a spinal cord injury may have different baseline perceptions of self-efficacy related to their ability to eat a healthy diet and exercise regularly compared to those with a traumatic brain injury or stroke.Health interventions should be tailored to encompass disability-specific barriers which may impact an individual's health-related self-efficacy.

Formative evaluation of an exercise training program for persons with multiple sclerosis who are wheelchair users

Exercise training is an effective and safe second-line therapy for improving multiple sclerosis (MS) symptoms and disease progression among adults. This study aimed to determine the appropriateness of a novel exercise training program for wheelchair users with MS. Ten wheelchair users with MS were recruited from a previous cross-sectional research study to attend one of three focus groups with 3-4 participants that lasted between 69 and 87 min. The focus groups were conducted online using a semi-structured format and participants were invited to complete an evaluation survey. During the focus groups, participants provided qualitative feedback regarding the exercise prescription, exercise modes (resistance and aerobic), training manual, exercise equipment, fitness tracker, rating scale, newsletters, logbook, and coaching. Most feedback focused on minor considerations such as avoiding the color red as it can be an issue for individuals with optic neuritis. Among quantitative evaluation survey ratings, coaching calls were rated the highest 4.7 ± 0.4 on a 5-point scale, followed by the exercise prescription (4.4 ± 0.8) and fitness tracker (4.3 ± 0.9). Focus group participants provided invaluable feedback for finalizing a novel exercise training program for wheelchair users with MS and provided focal suggestions for further improvements.

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.

Effectiveness and feasibility of the workout on wheels internet intervention (WOWii) for individuals with spinal cord injury: a randomized controlled trial

Study design

Randomized-controlled trial (RCT) with immediate intervention (IMM) and wait-list control (WLC) groups; WLC participants received the intervention during delivery to subsequent cohorts.

Objectives

Investigate the effectiveness and feasibility of a virtually-delivered exercise intervention.

Setting

Home and community.

Methods

A total of 168 middle-aged (49.6 [12.3] years old) men (57%) and women (43%) who lived an average 15.5 (12.3) years with spinal cord injury (SCI) participated. The 16-week program provides users (a) website access with exercise information, resources, and 16 skill-building modules; (b) virtual 60-minute, group-based weekly meetings; and (c) a starter package of exercise equipment. Primary outcomes included subjective physical activity (IPAQ) and objective exercise (Polar A300 wrist-based activity monitor and H7 heart rate strap). Secondary outcomes included fitness indices during a maximal arm crank test, plus self-reported exercise barriers, exercise self-efficacy, and goal-directed thinking.

Results

RCT results indicate significant between group differences in participants’ self-reported weekly time spent in vigorous-intensity PA and goal directed thinking but not for fitness changes. Data combined for IMM and WLC participants from Polar monitoring show participants performed 150 min per week of aerobic exercise plus reported significantly greater time spent in moderate-PA, vigorous-PA, self-efficacy for exercise and nutrition, goal directed thinking, and exercise barriers. Oxygen uptake (V̇O₂ peak) and power output (watts max) were the only physiologic measures to demonstrate significant change, with a moderate effect size.

Conclusion

This virtually-delivered program offers a promising approach to increase exercise among those with SCI and may help participants perceive fewer motivational barriers and greater self-efficacy.

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.

Prolonged exposure therapy for PTSD among spinal cord injury survivors: Study protocol for a randomized controlled trial

The National Spinal Cord Injury Statistical Center estimates 294,000 people in the US live with a spinal cord injury (SCI), with approximately 17,810 new cases each year. Although the physical outcomes associated with SCI have been widely studied, the psychological consequences of sustaining a SCI remain largely unexplored. Scant research has focused on posttraumatic stress disorder (PTSD) in this population, despite prevalence estimates suggesting that up to 60% of individuals with SCI experience PTSD post-injury, compared to only 7% of the general US population. Fortunately, prolonged exposure therapy (PE) is a well-researched and highly effective treatment for PTSD. However, no trauma focused exposure-based therapy for PTSD (e.g. PE) has not yet been tested in a SCI population. Thus, we aim to conduct the first test of an evidence-based intervention for PTSD among patients with SCI. Adults with SCI and PTSD (N = 60) will be randomly assigned to either: (1) 12-sessions of PE (2-3 sessions per week) or (2) a treatment as usual (TAU) control group who will receive the standard inpatient rehabilitation care for SCI patients. Primary outcomes will be assessed at 0, 6, 10, and 32 weeks.

Barriers and Facilitators to Lifestyle Intervention Engagement and Weight Loss in People Living With Spinal Cord Injury

Background: Individuals living with spinal cord injury (SCI) have a high prevalence of obesity and unique barriers to healthy lifestyle. Objective: To examine barriers and facilitators to engagement and weight loss among SCI participants enrolled in the Group Lifestyle Balance Adapted for individuals with Impaired Mobility (GLB-AIM), a 12-month intensive lifestyle intervention. Methods: SCI participants (N = 31) enrolled in a wait-list, randomized controlled trial where all participants received intervention between August 2015 and February 2017. Analyses of pooled data occurred in 2020 to examine cross-sectional and prospective associations of hypothesized barriers and facilitators with (1) intervention engagement, comprised of attendance and self-monitoring, and (2) percent weight change from baseline to 12 months. We performed multivariable linear regression on variables associated with outcomes at p < .05 in bivariate analyses and controlled for intervention group. Results: Participants were middle-aged (mean age, 48.26 ± 11.01 years), equally male (50%) and female, White (80.7%), and unemployed (65.6%). In participants who completed baseline surveys (n = 30), dietary self-efficacy explained 26% of variance in engagement (p < .01); among the 12-month study completers (n = 22, 71.0%), relationship issues explained 23% of variance in engagement (p < .01). Money problems, health issues unrelated to SCI, lack of motivation, and experimental group explained 57% of variance in weight loss (p for model < .01), with lack of motivation uniquely explaining 24% of variance (p < .01). Conclusion: Improving engagement and weight loss for persons with SCI in the GLBAIM program may be achieved by addressing lack of motivation, relationship issues, and nutrition self-efficacy.

Group Lifestyle Balance Adapted for Individuals With Impaired Mobility: Outcomes for 6-Month RCT and Combined Groups at 12 Months

INTRODUCTION

This study examines the feasibility and effectiveness of an intensive lifestyle intervention adapted for people with impaired mobility.

STUDY DESIGN

This was a randomized, wait-list controlled trial. The experimental group immediately received the 12-month weight loss program; the wait-list control group received it after a 6-month delay. Between-group comparisons were conducted for the 6-month RCT study design. Repeated measures were conducted for both groups combined after receiving the 12-month intervention. Data were collected August 2015-February 2017 and analyzed in 2017.

SETTING/PARTICIPANTS

A community-based sample received 23, group-based sessions via a mix of telephone and in-person sessions in a hospital-based setting. Participants with impaired mobility (n=66) were middle-aged (49.80 [SD=11.37] years), mostly White (66.7%), female (66.7%), and most commonly had spinal cord injury (47.0%).

INTERVENTION

The 12-month intervention delivered 23 group-based sessions that promoted weight loss through reducing caloric intake and increasing physical activity.

MAIN OUTCOME MEASURES

Primary outcomes were effectiveness measured as change in weight and time spent in moderate physical activity. Feasibility was assessed in 12-month combined group analyses, measured as retention, attendance, and dietary self-monitoring.

RESULTS

The 6-month RCT results showed that the immediate and delayed groups differed significantly (p<0.05) in weight (-1.66 [SD=4.42] kg loss vs 0.05 [SD=4.15] kg gain) and moderate physical activity (52.93 [SD=90.74] minutes/week increase vs -14.22 [SD=96.02] minutes/week decrease), accounting for baseline weight, time with disability, and age of onset. The 12-month results with groups combined demonstrated 74.2% retention and 77.7% core session attendance. Self-monitoring was higher in the delayed group (77.3%), who used a smartphone app, than the immediate group (47.3%), who mostly used paper trackers. Participants achieved significant 12-month weight loss of 3.31 (SD=10.13) kg (d=0.33) in mixed modeling analyses with groups combined yet did not significantly increase moderate physical activity.

CONCLUSIONS

Group Lifestyle Balance Adapted for Individuals with Impaired Mobility is a feasible, effective approach to teach healthy lifestyle skills to individuals with mobility impairment, yielding modest weight loss and enhanced self-efficacy.

Website Redesign of a 16-Week Exercise Intervention for People With Spinal Cord Injury by Using Participatory Action Research

Background

People with spinal cord injury (SCI) are at higher risk for numerous preventable chronic conditions. Physical activity is a protective factor that can reduce this risk, yet those with SCI encounter barriers to activity and are significantly less likely to be active. Limited evidence supports approaches to promote increased physical activity for those with SCI.

Objective

Building upon our previous theory- and evidence-based approach to increase participation in regular physical activity for those with SCI, this study aimed to use a participatory action research approach to translate a theory-based intervention to be delivered via the Web to individuals with SCI.

Methods

A total of 10 individuals with SCI were invited to participate in consumer input meetings to provide the research team with iterative feedback on an initial website designed as a platform for delivering a theory-based exercise intervention.

Results

A total of 7 individuals with SCI whose average age was 43.6 years (SD 13.4) and lived an average age of 12.5 years (SD 14.9) with SCI met on 2 occasions to provide their feedback of the website platform, both on the initial design and subsequently on the revamped site. Their iterative feedback resulted in redesigning the website content, format, and functionality as well as delivery of the intervention program.

Conclusions

The substantially redesigned website offers an easier-to-navigate platform for people with SCI with greater functionality that delivers information using a module format with less text, short video segments, and presents more resources. Preliminary testing of the site is the next step.

Weight Loss After Stroke Through an Intensive Lifestyle Intervention (Group Lifestyle Balance-Cerebrovascular Accident): Protocol for a Randomized Controlled Trial

BACKGROUND

Weight gain can be a consequence of stroke, or cerebrovascular accident (CVA), because of impaired mobility, behavioral and emotional disorders, and sensory losses. Weight gain increases the patient's risk of recurrent stroke and chronic diseases, such as diabetes, metabolic syndrome, and pulmonary and heart disease. Approaches to weight loss in this population are lacking, although necessary because of the unique physiological and cognitive needs of persons after a stroke. Evidence shows that intensive behavioral therapy interventions that address both physical activity and diet offer the greatest potential for weight loss. The Group Lifestyle Balance (GLB) intervention is a 12-month, evidence-based weight loss program that has been used extensively with the general population; this program was modified to meet the needs of people who have had a stroke (GLB-CVA).

OBJECTIVE

This randomized controlled trial (RCT) aims to examine the efficacy of the GLB-CVA on weight and secondary outcomes, compared with that of a waitlist control group.

METHODS

This RCT will enroll and randomize 64 patients over an 18-month period.

RESULTS

Currently, 51 people are waitlisted, with 23 out of 51 screened and 16 out of 23 eligible.

CONCLUSIONS

It is anticipated that the findings from this RCT will contribute to the evidence base regarding weight loss strategies for people living with stroke.

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.

Disproportionate Prevalence Rate of Prisoners With Disabilities

Previous research suggests that prisoners have a higher rate of disability than non-institutionalized adults. This study used nationally representative data to update the prevalence rate, identify correlates of disability, and evaluate disability-related disparities in use of prison-based educational services, vocational programs, and work assignments. Data were obtained from 18,185 prisoners interviewed in the 2004 Survey of Inmates in State and Federal Correctional Facilities. Survey logistic regression procedures were conducted using Stata 13. Disability prevalence remained substantially higher among prisoners than among the non-institutionalized population. Prisoners were more likely to report specific learning, sensory, and speech-related disabilities than non-institutionalized adults. Prisoners with at least one type of disability had more criminogenic risk factors and come from a more disadvantaged background than prisoners without disability. Prisoners with disabilities were also less likely to utilize vocational programs and work assignments but were more likely to use educational programs than prisoners without disabilities. In summary, 41% of prisoners reported a disability, most commonly, learning disabilities. Prisoners with disabilities were identified as an at-risk group for recidivism, given their pre-incarceration experiences, and limited vocational and work-related training received in prison.

Self-Management Interventions to Prevent Depression in People with Mobility Limitations

Introduction

This focused review reports on the impact of self-management interventions on depression in people with a mobility disability.

Method

There were two phases to the search including a comprehensive scoping review of the literature examining multiple secondary conditions impacted by self-management programs (Phase 1) and a focused review of the literature detailing the impact of self-management interventions on depression (Phase 2). CINAHL, PubMed, and PsyclNFO were searched for articles published between January 1988 through August 2014 and studies were screened by the first author based on specific inclusion and exclusion criteria.

Results

Twenty-five studies met criteria with results, demonstrating a mixed effect of self-management programs on depression. Sixteen studies included an intervention and control/comparison group, of which eight (50%) had a significant effect on depression. A further nine studies did not include a control/comparison group and five found significant changes in depression and four found no change. Eighteen out of 25 studies (72%) were rated as having moderate-to-high bias and nine different outcome measures were used across studies.

Discussion

Based on the mixed findings and varied approaches adopted for intervention and outcome assessment, future research should adopt a more rigorous methodological approach to examine self-management interventions on depression.

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.

Impact of disability and chronic conditions on health

BACKGROUND

Today one in five Americans have a disability and nearly half of Americans experiences a chronic condition. Whether disability results from or is a risk factor for chronic conditions, the combined effects of disability and chronic conditions warrants further investigation.

OBJECTIVES

Examine the added impact of chronic conditions among those with and without disability on self-reported health status and behaviors.

METHODS

2009 Behavioral Risk Factor Surveillance System (BRFSS) data were analyzed to examine the association of disability with unhealthy behaviors and poor health stratified by number of self-reported chronic conditions (0, 1, or 2+). Linear and logistic regression models accounting for the complex survey weights were used.

RESULTS

Participants with disability were 6 times more likely to report fair/poor self-rated health, reported 9 more unhealthy days in a month and 6 more days in a month when poor health kept them from usual activities, were 4 times more likely to be dissatisfied with life, had greater odds of being a current smoker, and were less likely to be physically active. Presence of chronic conditions in addition to disability was associated, in a dose-response manner, with poor health status and unhealthy behaviors.

CONCLUSIONS

People living with both chronic diseases and disability are at substantially increased risks for poor health status and unhealthy behaviors, further affecting effective management of their chronic conditions. Multi-level interventions in primary care and in the community that address social and environmental barriers that hinder adults with disability from adopting more healthy lifestyles and improving health are needed.

Self-Management Interventions to Prevent the Secondary Condition of Pain in People with Disability Due to Mobility Limitations

Introduction

This focused review examines the use and effectiveness of self-management strategies in preventing or managing pain, which is among the most common secondary conditions faced by individuals with a mobility disability.

Methods

This focused review was part of a two-phase comprehensive scoping review. Phase I was a comprehensive scoping review of the literature targeting multiple outcomes of self-management interventions for those with mobility impairment, and Phase II was a focused review of the literature on self-management interventions that target pain as a primary or secondary outcome. Two authors searched CINAHL, PubMed, and PsyclNFO for papers published from January 1988 through August 2014 using specified search terms. Following the scoping review, the authors independently screened and selected the studies and reviewed the eligible studies, and the first author extracted data from the included studies.

Results

The scoping review yielded 40 studies that addressed pain self-management interventions for those living with mobility impairment. These 40 accumulated papers revealed a heterogeneous evidence base in terms of setting (clinic, community, and online), target populations, intervention duration (3 weeks to 24 months), and mode (health-care providers and lay leaders). Most of the reviewed studies reported that the self-management intervention led to significant reduction of pain over time, suggesting that self-management may be a promising approach for addressing pain experienced by people who live with mobility limitations.

Discussion

This review also reveals moderate-to-high bias across studies, and findings indicate that future research should enhance the methodological quality to provide stronger evidence about the effectiveness of self-management strategies for reducing pain among those with mobility impairments.

Reach of the Montana Cancer Control Program to Women with Disabilities

Women with disabilities have lower screening rates for breast and cervical cancer with some evidence suggesting that people with disabilities experience higher cancer mortality and may receive a different course of treatment. This study examined whether women with and without disabilities using Montana Cancer Control Program (MCCP) differ in use of breast (BCS) and cervical (CCS) screening services, receipt of and follow up for inconclusive or abnormal results, and compliance with BCS and CCS US Preventive Services Task Force recommendations. Study participants were women eligible for MCCP screening services between November 2012 and October 2014, with eligibility based on insurance status (underinsured/no insurance), income requirements (<200 % poverty based on income/household size), and age. The data derive from participant self-report (demographic, disability, and health history including previous mammogram or Papanicolaou test) and MCCP records of screening tests (clinical breast exam, mammogram, or Pap test), results, and follow up visits. About 11.5 % of MCCP participants reported having a disability. MCCP recipients with a disability were significantly older, more likely to be non-Hispanic White, and more likely to have poor health profiles. Disability status did not affect use of MCCP screening services, screening outcome, or follow up for inconclusive or abnormal results. However, women with disability had significantly lower BCS and CCS compliance (based on US Preventive Task Force guidelines) than women without disability, which persisted in adjusted analyses controlling for other significant factors. The MCCP is reaching un/underinsured Montana women with disabilities. While disability status in this sample was not related to use of MCCP services or screening outcome, MCCP recipients with disabilities have significantly lower BCS and CCS compliance. Efforts to increase compliance for un/underinsured Montana women with a disability are warranted.

The Role of Age in Moderating the Association Between Disability and Light-Intensity Physical Activity

PURPOSE

There's a lack of evidence on the association between light-intensity physical activity and disability. This study examines the relationships in activity by self-reported physical function in five domains (i.e., activities of daily living [ADL], instrumental ADL, leisure activities, lower extremity, and general activities), and whether this association varies by age.

DESIGN

Cross-sectional.

SETTING

Data from National Health and Nutrition Examination Survey 2003-2004 and 2005-2006 waves.

SUBJECTS

Participants included 5700 men and women ages 20 to 85 years.

MEASURES

Difficulty with various activities was measured with the Physical Functioning Questionnaire, accelerometer-measured physical activity, demographics, and self-rated health.

ANALYSIS

Ordinary least squares regression models were run to examine the relationship between physical function in each domain, light-intensity activity, and the moderating effect of age. Analyses controlled for body mass index, moderate-to-vigorous-intensity activity, self-reported health, accelerometer wear time, and gender.

RESULTS

Little variation was seen in light-intensity physical activity among younger adults regardless of disability status. Older adults reporting difficulty with activities engaged in significantly less light-intensity physical activity compared to those with no disability (271.8 vs. 316.5 minutes). Age significantly moderated the association between light-intensity physical activity and leisure activities (p = .048), and lower extremity mobility (p = .039). Age did not moderate other domains of disability.

CONCLUSION

Younger age may be protective regarding the influence of disability on light-intensity activity. In addition, disability may be more debilitating for some older individuals. Interventions to increase light-intensity activity should aim to address disability at all ages, with increased attention for older adults.

Exercise for everyone: a randomized controlled trial of project workout on wheels in promoting exercise among wheelchair users

OBJECTIVE

To compare the effectiveness of 2 home-based behavioral interventions for wheelchair users to promote exercise adoption and maintenance over 12 months.

DESIGN

Randomized controlled trial, with participants stratified into groups based on disability type (stable, episodic, progressive) and support partner availability.

SETTING

Exercise occurred in participant-preferred locations (eg, home, recreation center), with physiological data collected at a university-based exercise laboratory.

PARTICIPANTS

Inactive wheelchair users (N=128; 64 women) with sufficient upper arm mobility for arm-based exercise were enrolled. Participants on average were 45 years of age and lived with their impairment for 22 years, with spinal cord injury (46.1%) most commonly reported as causing mobility impairment.

INTERVENTIONS

Both groups received home-based exercise interventions. The staff-supported group (n=69) received intensive exercise support, while the self-guided group (n=59) received minimal support. Both received exercise information, resistance bands, instructions to self-monitor exercise, regularly scheduled phone calls, and handwritten cards.

MAIN OUTCOME MEASURES

The primary outcome derived from weekly self-reported exercise. Secondary outcomes included physical fitness (aerobic/muscular) and predictors of exercise participation.

RESULTS

The staff-supported group reported significantly greater exercise (∼17min/wk) than the self-guided group over the year (t=10.6, P=.00), with no significant between-group difference in aerobic capacity (t=.76, P=.45) and strength (t=1.5, P=.14).

CONCLUSIONS

Although the staff-supported group reported only moderately more exercise, the difference is potentially clinically significant because they also exercised more frequently. The staff-supported approach holds promise for encouraging exercise among wheelchair users, yet additional support may be necessary to achieve more exercise to meet national recommendations.

Assessing stress in disability: developing and piloting the Disability Related Stress Scale

BACKGROUND

Stress negatively influences health, but few scales capture unique stressors encountered by people with physical disability.

OBJECTIVE/HYPOTHESIS

Conduct a pilot study to develop and evaluate the factor structure of a stress measure targeting unique stressors facing people with physical limitations due to impaired movement of the upper and lower extremities.

METHODS

Development of the Disability Related Stress Scale (DRSS) included: (1) obtaining input regarding content and items from focus groups and outside experts and (2) piloting the instrument. Participants recruited from an independent living center attended a focus group or completed the pilot survey. The piloted measure was a 107 item two-part survey. Part 1 assessed stressors encountered over the past week and Part 2 assessed stressors encountered over the past six months. Participants included a convenience sample of 143 adults who experienced a physical limitation; 26 attended focus groups and 117 completed the instrument. Respondents were predominantly women (60%), Caucasian (58%), and unemployed (92%). Respondents were 50.51 ± 14.46 years old and had lived with their disability for 15.64 ± 13.04 years.

RESULTS

Exploratory factor analyses revealed a 4-factor solution for Part 1 and a 2-factor solution for Part 2 of the DRSS. Estimates of internal consistency (Part 1 Cronbach's α = .78-84; Part 2 Cronbach's α = .72) and factor loadings (.40-1.00 for Part 1; .43-.87 for Part 2) indicate adequate reliability for all subscales.

CONCLUSIONS

Preliminary results provide initial support for the instrument's reliability and factor structure although further validation studies are warranted.

Truth be told: evidence of wheelchair users' accuracy in reporting their height and weight

OBJECTIVES

To examine whether wheelchair users' self-reports of height and weight differed significantly from direct measurements and whether weight category classifications differed substantially when based on self-reported or measured values.

DESIGN

Single group, cross-sectional analysis. Analyses included paired t tests, chi-square test, analysis of variance, and Bland-Altman agreement analyses.

SETTING

A university-based exercise lab.

PARTICIPANTS

Community-dwelling wheelchair users (N=125).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Participants' self-reported and measured height, weight, and body mass index.

RESULTS

Paired t tests revealed that there were significant differences between wheelchair users' self-reported and measured values for height (difference of 3.1±7.6cm [1.2±3.0in]), weight (-1.7±6.5kg [-3.6±14.2lb]), and BMI (-1.6±3.3). These discrepancies also led to substantial misclassification into weight categories, with reliance on self-reported BMI underestimating the weight status of 20% of the sample.

CONCLUSIONS

Our findings suggest that similar to the general population, wheelchair users are prone to errors when reporting their height and weight and that these errors may exceed those noted in the general population.

Determining paralysis prevalence in the United States

BACKGROUND

Estimates of paralysis vary widely, largely owing to a lack of standard definition and nontargeted survey approaches. Like other poorly understood conditions such as fibromyalgia, chronic fatigue, or chronic pain, paralysis falls outside the scope of clearly defined medical diagnosis, further complicating surveillance efforts. This inability to identify accurate prevalence makes developing policy interventions around the needs of many persons with these disabilities problematic. The objectives were to investigate how paralysis is being measured in the United States and to examine the validity of prevalence estimates based on current approaches.

METHODS

We reviewed existing measurement instruments and surveyed 139 agencies and organizations to determine how they capture paralysis data.

RESULTS

There is a widespread reliance on ICD coding or broad functional capabilities for most state or federal agencies. Many organizations serving consumers depend on state registries for discrete conditions in which paralysis is not directly measured.

CONCLUSIONS

Improved paralysis prevalence data will benefit from a more functional definition consistent with ICF guidelines, which can be part of future surveillance efforts at state and federal levels.

Access to polling places in the 2004 Presidential election: the experience of one metropolitan midwestern city

According to federal law, polling places must be accessible to persons with disabilities. The rate of compliance with these laws, however, is not known. Our purpose was to determine whether polling places in the Greater Kansas City area were physically accessible to persons with disabilities. Students, faculty, and staff members from four professional programs representing two universities completed surveys at 128 polling places on the day of the 2004 Presidential election. Over the 14 items of interest, compliance ranged from 75% to 99%. The highest rate of deficiencies was found in the lack of a ramp with a handrail to the entrance of the polling place. Only 43% of the polling places were compliant in all of the 14 survey items. Despite laws mandating that polling places be accessible to persons with disabilities, restrictions in access persist. Persons with disabilities may still find polling places inaccessible on Election Day.

Promoting physical activity among women with mobility impairments: a randomized controlled trial to assess a home- and community-based intervention

OBJECTIVE

To assess the effectiveness of an intervention to promote physical activity and fitness in physically disabled women.

DESIGN

Randomized controlled trial.

SETTING

Home or community.

PARTICIPANTS

Seventy-five adult women with mobility limitations.

INTERVENTION

Incorporated behavioral techniques, social support, and education to promote exercise.

MAIN OUTCOME MEASURES

Fitness measures included weight, body mass index, resting blood pressure and heart rate, time to complete a mobility course, and heart rate during and blood pressure after navigating the course. Also collected self-reported experience of secondary conditions and weekly self-reports of physical activity.

RESULTS

We found no significant fitness differences between groups, except for peak heart rate. However, paired t tests of the physical activity data revealed the experimental group significantly increased its total weekly physical activity minutes (P=.04), and the increase in weekly cardiovascular activity approached significance (P=.06).

CONCLUSIONS

The experimental group did not experience better fitness or fewer secondary conditions than the controls. However, the experimental group's physical activity data indicate that this group significantly increased its activity over 6 months. Thus, although this study did not detect health changes, it showed that mobility-impaired women can adopt and maintain a physical activity program.
