Using Smartphones to Improve Physical Activity Levels of Individuals With Spinal Cord Injury

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.
