Background: People with spinal cord injury (SCI) have elevated risk of cardiometabolic syndrome (CMD), are inactive, and face barriers to physical activity (PA). Lifestyle behavior change, i.e., PA at recommended levels, can modify CMD. WHEEL-LEARN applied behavioral theory to reduce barriers. Aims evaluated usability, acceptability, and feasibility, and proof of concept on leisure time PA, quality of life, exercise self-efficacy, social support, and enjoyment. Methods. Single group mixed methods pre-post study was conducted. Each week for 4 weeks, one lesson was emailed, and a 1-hour group online session was held. Results: Participants with SCI (N=17) were age [53.63±10.01 years], majority female (10/16=62%) and white (15/16=94%)]. Pre-post System Usability Scale scores showed excellent perceived usability. Participant’s comments indicated acceptability. Feasibility was seen with attendance, not knowledge review completion. Participants significantly increased volume of moderate to heavy LTPA pre [median (interquartile range, IQR)] [60.00(20.00,165.00)] to post [114.50(114.50,196.50)], p=0.049]. Quality of life significantly increased pre [71.00(57.50,84.75)], to post [78.50(68.25,94.50), p=0.003]. Self-efficacy significantly increased pre [31.50(27.25,33.00] to post [33.00(31.00,38.00), p=0.038]. Social support did not change. Enjoyment was demonstrated [63.00(58.50,66.50)]. Conclusion. WHEEL-LEARN was usable, feasible for attendance, and enjoyable. Participants (96%) achieved 150 min/week of moderate intensity PA and increased self-efficacy and quality of life.
