Correlates of adherence in a home-based, self-managed exercise program tailored to wheelchair users with spinal cord injury

mHealth-Based Just-in-Time Adaptive Intervention to Improve the Physical Activity Levels of Individuals With Spinal Cord Injury: Protocol for a Randomized Controlled Trial

BACKGROUND

The lack of regular physical activity (PA) in individuals with spinal cord injury (SCI) in the United States is an ongoing health crisis. Regular PA and exercise-based interventions have been linked with improved outcomes and healthier lifestyles among those with SCI. Providing people with an accurate estimate of their everyday PA level can promote PA. Furthermore, PA tracking can be combined with mobile health technology such as smartphones and smartwatches to provide a just-in-time adaptive intervention (JITAI) for individuals with SCI as they go about everyday life. A JITAI can prompt an individual to set a PA goal or provide feedback about their PA levels.

OBJECTIVE

The primary aim of this study is to investigate whether minutes of moderate-intensity PA among individuals with SCI can be increased by integrating a JITAI with a web-based PA intervention (WI) program. The WI program is a 14-week web-based PA program widely recommended for individuals with disabilities. A secondary aim is to investigate the benefit of a JITAI on proximal PA, defined as minutes of moderate-intensity PA within 120 minutes of a PA feedback prompt.

METHODS

Individuals with SCI (N=196) will be randomized to a WI arm or a WI+JITAI arm. Within the WI+JITAI arm, a microrandomized trial will be used to randomize participants several times a day to different tailored feedback and PA recommendations. Participants will take part in the 24-week study from their home environment in the community. The study has three phases: (1) baseline, (2) WI program with or without JITAI, and (3) PA sustainability. Participants will provide survey-based information at the initial meeting and at the end of weeks 2, 8, 16, and 24. Participants will be asked to wear a smartwatch every day for ≥12 hours for the duration of the study.

RESULTS

Recruitment and enrollment began in May 2023. Data analysis is expected to be completed within 6 months of finishing participant data collection.

CONCLUSIONS

The JITAI has the potential to achieve long-term PA performance by delivering tailored, just-in-time feedback based on the person's actual PA behavior rather than a generic PA recommendation. New insights from this study may guide intervention designers to develop engaging PA interventions for individuals with disability.

Developing a mobile exercise program for individuals with Spinal Cord Injury: Stakeholder perceptions of app features and implementation determinants

BACKGROUND

Individuals with Spinal Cord Injury (SCI) often experience physical deconditioning, leading to long-term health challenges. While regular exercise can offer substantial health benefits, adherence to exercise guidelines among individuals with SCI is hindered by barriers such as inaccessibility. Exercise programs using the mobile application (App) tailored to individual needs present a promising solution for promoting exercise adherence among individuals with SCI.

OBJECTIVE

This study aimed to identify factors contributing to the successful implementation of an app-based home exercise program for individuals with SCI and gather user feedback on app preferences, functionality, and features.

METHODS

Guided by the Consolidated Framework for Implementation Research (CFIR), twenty-six clinicians completed an expert panel survey to rank factors influencing the implementation of an app-based intervention for increasing exercise adherence for individuals with SCI. CFIR-selected factors and app quality features obtained from the Mobile Application Rating Scale (MARS) framework were discussed in seven focus groups with 23 individuals with SCI, 6 caregivers, and 6 clinicians.

RESULTS

The expert survey identified adaptability, complexity, evidence strength/quality, relative advantage, knowledge/beliefs about the initiative, and execution as the key CFIR factors that affected the intervention's success. Major themes emerging from focus groups with individuals with SCI and caregivers included usability, instruction and guidelines, user-friendly interface, and clinician interaction. In contrast, clinicians mentioned themes such as the representation of the SCI population, time commitment, accessibility, and equipment.

CONCLUSIONS

The study highlights the significance of incorporating these determinants into future designs to develop app-based home exercise interventions for individuals with SCI.

Development and Feasibility of a Group Tele-Exercise Program for Individuals With Spinal Cord Injury

BACKGROUND AND PURPOSE

More than 50% of individuals with spinal cord injury (SCI) report no regular exercise due to numerous barriers to participation. Tele-exercise services offer viable solutions to reduce barriers. However, limited evidence for SCI-specific tele-exercise programs is available. The purpose of this study was to evaluate the feasibility of a synchronous group tele-exercise program designed for individuals with SCI.

METHODS

Explanatory sequential mixed-methods design assessed feasibility of a synchronous 2-month biweekly group tele-exercise program for individuals with SCI. Numeric measures of feasibility were first collected (recruitment rate, sample features, retention, attendance), followed by postprogram interviews with participants. Thematic analysis of experiential feedback elaborated on numeric findings.

RESULTS

Eleven volunteers (ages = 49.5 ± 16.7 years) with SCI (range: 2.7-33.0 years) enrolled within 2 weeks of recruitment initiation. Retention was 100% retention at program completion. Median number of live classes attended per participant was 10 (62.5%). Participants described that attendance and satisfaction were facilitated by program-specific features including coinstruction by instructors with SCI-specific knowledge and lived experience, as well as group structure. Participants reported increased exercise knowledge, confidence, and motivation.

DISCUSSION AND CONCLUSIONS

This study demonstrated feasibility of a synchronous group tele-exercise class for individuals with SCI. Key features facilitating participation include class length, frequency, coleadership by individuals familiar with SCI and exercise instruction, and group motivation. These findings begin to examine a viable tele-service strategy that could be employed as a bridge among rehabilitation specialists, community fitness instructors, and clients with SCI to increase physical activity access and behavior.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1 available at: http://links.lww.com/JNPT/A442 ).

Increasing Physical Activity in Persons With Spinal Cord Injury With an eHealth-Based Adaptive Exercise Intervention: Protocol for a Sequential Multiple Assignment Randomized Trial

BACKGROUND

Participating in an adequate amount of physical activity to acquire health benefits is challenging for people with spinal cord injury (SCI) due to personal and logistic barriers. Barriers in the built and social environments may include lack of transportation, lack of accessible facilities or programs, and lack of training among fitness personnel. Low self-efficacy, lack of self-regulation skills, and improper outcome expectations are examples of personal barriers. Current approaches to investigating physical activity programs in people with SCI have been limited to traditional "one-size-fits-all" design, which has yielded low adherence rates, high dropout rates, and participants not maintaining physical activity levels at follow-up.

OBJECTIVE

The primary aim of this study is to test the feasibility of a tele-exercise program that applies an adaptive intervention design for 30 adults with SCI, targeting increases in adherence to the exercise program and physical activity participation.

METHODS

The Sequential Multiple Assignment Randomized Trial for Home-based Exercise and Lifestyle Tele-Health (SMART-HEALTH) is a 12-week, home-based, movement-to-music (M2M) program. The goal of a SMART-designed study is to develop an adaptive intervention that modifies support provisions based on response levels. In SMART-HEALTH, 2 groups of participants will undergo 3-week and 6-week asynchronous M2M interventions in the first phase. Participants who did not achieve the desired adherence rate (≥95% of video watch minutes) will be rerandomized into M2M Live (switch) or individualized behavioral coaching (augmented with the asynchronous M2M program). The study will primarily assess rates of recruitment or enrollment, adherence and retention, timing to identify nonresponders, and scientific outcomes (eg, physical activity and exercise self-efficacy). The study will qualitatively evaluate the acceptability of the study using semistructured interviews among participants who complete the 12-week intervention.

RESULTS

Recruitment procedures started in June 2022. All data are expected to be collected by September 2023. Full trial results are expected to be published by March 2024. Secondary analyses of data will be subsequently published. Results will include exercise adherence rates; changes in self-reported physical activity levels and blood pressure; and changes in secondary conditions including pain, sleep, and fatigue. Thematic analysis of semistructured interviews will include results on participant enjoyment and acceptability of SMART-HEALTH and inform modifications for future delivery of the program.

CONCLUSIONS

This study will strengthen our understanding of the potential benefits of the tele-exercise intervention for people with SCI and build upon adaptive intervention design and its delivery strategies that aim to increase adoption and sustainable exercise behavior. This pilot trial will inform future SMART-designed studies and provide new and innovative strategies for investigating intervention effects on physical activity behavior in the SCI population.

Dissemination and implementation strategies for physical activity guidelines among adults with disability, chronic conditions, and pregnancy: a systematic scoping review

BACKGROUND

Physical activity guidelines for adults with disability, chronic conditions, and pregnancy (i.e., specific populations) have been developed to provide guidance for engaging in physical activity. However, specific populations remain considerably less physically active compared to the general population, presenting a knowledge-practice gap.

PURPOSE

The purpose of this systematic scoping review was to identify and evaluate strategies for disseminating and implementing physical activity guidelines among specific populations and/or stakeholders (e.g., healthcare professionals) in Canada.

METHODS

Five search approaches (peer-reviewed literature databases, grey literature database, custom Google search engines, targeted web-based searches, and content expert consultation) identified records documenting and/or evaluating strategies that had been used to disseminate or implement guidelines from a predetermined list. Systematic and scoping review protocols were followed. Risk of bias assessments were conducted for all studies that evaluated strategies.

RESULTS

Eighty-one records reported dissemination strategies (n = 42), implementation strategies (n = 28), or both (n = 11). Twenty-two studies reporting on 29 evaluated strategies were deemed "serious" or "high" risk of bias. Common guideline dissemination and implementation strategies are deliberated and recommendations for future practice are made.

CONCLUSIONS

Findings may inform future dissemination and implementation efforts for physical activity guidelines in Canada or similar countries.

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.
