A Phase 2 interventional study of WI program and WI Program Reminder in Spinal Cord Injuries, sponsored by Temple University. Recruiting at 1 site in United States. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-06-24.

The overarching goal of this research study is to evaluate a sensor-enabled, just-in-time adaptive intervention (JITAI) strategy to increase and sustain physical activity levels among individuals with spinal cord injury (SCI) in their communities. A primary objective of this study is to evaluate the integration of a JITAI with a web-based physical activity intervention program. We hypothesize that the integration of web-based physical activity intervention program with JITAI will result in significantly higher physical activity levels compared to the standard web-based physical activity intervention program alone. A secondary objective of this study is to extend existing algorithms that use commercial wearable technology to robustly detect physical activity behaviors to facilitate the delivery of tailored just-in-time actionable feedback and physical activity recommendations for individuals with SCI.
The integration of the JITAI, which provides feedback and physical activity recommendations due to sensor-based assessments of physical activity, with a standard web-based physical activity intervention program will be tested via a clinical trial. Specifically, individuals with SCI will be randomized to web-based physical activity intervention program (WI) or web-based physical activity intervention program combined with the JITAI (WI + JITAI). Within the WI + JITAI arm, a micro-randomized trial - a clinical trial design for optimizing mobile-Health interventions - will be used to randomize participants several times a day to various types of tailored feedback and physical activity recommendations.
Aim 1: Evaluate the efficacy of the WI + JITAI compared to the standard WI alone. We hypothesize that the integration of WI + JITAI will result in significantly higher physical activity levels compared to the standard WI alone.
Aim 2: Use a micro-randomized trial design to optimize the delivery of just-in-time physical activity feedback and recommendations in promoting physical activity.
Aim 3: Investigate moderators of the effect of WI + JITAI vs. standard WI alone. Moderators will include age, gender, race/ethnicity, level of injury, function, mobility, pain, and fatigue.
The proposed study will yield novel insights about JITAIs and JITAIs combined with more traditional, WI programs, which will help researchers design engaging physical activity interventions for individuals with disability in the community that may improve their health and quality of life.

Participants in the WI arm will take part in the WI program (weeks 3 to 16). After the WI program is completed in week 16, the participants will transition to the physical activity sustainability phase which will include participants having continued access to the information provided during the WI program (weeks 17 to 24).

Participants in the WI + JITAI arm will take part in the WI program (weeks 3 to 16). After the WI program is completed in week 16, the participants will transition to the physical activity sustainability phase which will include participants having continued access to the information provided during the WI program (weeks 17 to 24). In addition, participants will have access to the JITAI that will provide just-in-time feedback and physical activity recommendations (weeks 3 to 24). The type of the feedback and recommendation messages in the WI + JITAI arm will be delivered using micro-randomization, which involves random selection of intervention components at each possible time of delivery.

This 14-week web-based physical activity intervention (WI) program was developed by the National Center on Health, Physical Activity and Disability. The WI program was developed with guidance from literature and practice in health behavior change and internet-based health promotion programming. The content and features of the WI program include motivational resource, updated weekly resources, and customizable features.
Participants will be provided with reminders to use the WI program
Participants will be provided with standard, tailored, or no goal for the day. The goal will focus on recommending minutes of moderate-intensity (or higher) physical activity and a reminder to perform strength exercises.
Participants will be provided with minutes of moderate-intensity (or higher) physical activity achieved, minutes of physical activity remaining, or no message.
Participants will be inquired through an ecological momentary assessment (EMA) if they received a JITAI physical activity message.
Participants will be inquired, through an ecological momentary assessment (EMA), if they performed aerobic and/or strength exercises for the day.
Participants will be inquired, through an ecological momentary assessment (EMA), about the time they plan to wake up next day. This information will be used to provide a goal setting message for next day.
Participants will have access to minutes of moderate-intensity (or higher) physical activity performed over the last 7 days.
Participants will have access to minutes of moderate-intensity (or higher) physical activity performed over the day.

Plan to share: Yes — Sharing of data generated by the proposed research study will be carried out in several different ways. We will make our results available both to the consumers with SCI and scientific community. Conversely, we would welcome collaboration with others who could make use of the information gained in this project. Temple University and its collaborators will remain Health Insurance Portability and Accountability Act (HIPAA) compliant and all data will remain free of identifiers and variables that could lead to disclosure of participant identity. During the study, preliminary analyses will be conducted at periodic intervals. Our plan is to disseminate our findings in the form of interdisciplinary peer-reviewed manuscripts and presentations at national and international conferences.
