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

Effect of Tele-exercise to Promote Empowered Movement for Individuals With Spinal Cord Injury (TEEMS) Program on Physical Activity Determinants and Behavior: A Mixed Methods Assessment

OBJECTIVE

To assess the effects of group tele-exercise participation on physical activity (PA) determinants and behavior as identified by social cognitive theory (SCT) in individuals with spinal cord injury (SCI).

DESIGN

This clinically registered non-randomized trial [NCT05360719] used a single-group parallel mixed methods design. Quantitative and qualitative primary measures were assessed at pre-program and after 8-week intervention completion (post-program), with an additional 8-week period retention to capture quantitative assessments only.

SETTING

Community.

PARTICIPANTS

Individuals with chronic SCI (N=22, injury duration 2-50 years) aged 26-68 years (10 male/12 female).

INTERVENTION

An 8-week group tele-exercise program for individuals with SCI consisting of biweekly 60-minute classes delivered via live Web-conferencing software.

MAIN OUTCOME MEASURES

Exercise self-efficacy (Exercise Self-efficacy Scale for SCI: ESES), outcome expectations for exercise (Multidimensional Outcome Expectations for Exercise: MOEES), weekly PA minutes measured through quantitative assessments (Leisure Time PA Questionnaire for SCI: LTPAQ), and parallel qualitative thematic analysis of focus group interview transcripts.

RESULTS

Congruence between numeric and thematic findings was present for exercise self-efficacy and self-evaluative exercise outcome expectations. Improved exercise self-efficacy was influenced by exercise knowledge gained during program participation. Increased expectations of internal exercise outcomes, such as influence on psychological state and overall mood, occurred after program participation. Participant descriptions of the portability and sustainability of the program leading to added movement in everyday life were not reflected in the numeric scores of LTPAQ assessment.

CONCLUSIONS

Participation in an 8-week group tele-exercise program positively affected personal determinants of PA behavior immediately after participation. Future investigations should include a control group and biophysical PA measures such as wearable digital health devices.

Baseline Comparison of Exercisers and Nonexercisers With Spinal Cord Injury Enrolled in a Group Tele-Exercise Program

Background

Individuals with SCI are 1.5 times more likely to be sedentary compared to adults without disabilities or chronic health conditions. It is therefore imperative to develop and evaluate innovative facilitation strategies for physical activity behavior in this population.

Objectives

As an insightful step to creating and evaluating tailored physical activity interventions for individuals with SCI, we evaluated demographic, psychosocial, and physical characteristics of those who choose to engage in physical activity by enrolling in a group exercise study.

Design/Methods

We conducted a cross-sectional analysis detailing demographic features and baseline outcomes of those with SCI enrolled in a group tele-exercise study who were classified as regular exercisers versus nonregular exercisers per the American College of Sports Medicine exercise guidelines. Between-group differences for psychosocial and physical outcomes were assessed with chi-square and Mann-Whitney U tests (p < .05).

Results

Twenty-seven adult volunteers enrolled in the study (exercisers = 14, nonexercisers = 13). Groups were comparable for biological sex, gender identity, self-reported racial group(s), and current age. Exercisers demonstrated significantly shorter duration of injury compared to nonexercisers (p = .012). Exercisers exhibited significantly higher exercise self-efficacy (p = .017) and increased reported weekly minutes in vigorous intensity leisure time physical activity (p = .029).

Conclusion

Nonexercisers with SCI demonstrate increased injury duration and reduced exercise self-efficacy compared to active peers. These factors should be addressed in the design and delivery of SCI-specific physical activity interventions to increase the likelihood of this critical health behavior over time.
