ATOMIC (Active Teens Multiple Sclerosis) Physical Activity Research Program

The ATOMIC intervention consists of four primary components: one-on-one chats with a PA coach, informational posts, PA self-monitoring through an activity tracker and educational modules regarding different aspects of becoming PA delivered through the MS-specific PA app. An overarching goal of moving youth with MS towards meeting current Moderate to Vigorous Physical Activity (MVPA) recommendations will be used in addition to initial results from accelerometer monitoring and evaluation of current PA intentions to establish step goals, with planned weekly incremental increases (10% weekly to goal).

For a period of 6-months, participants will receive the control conditions that involve contact from study personnel and a nutritional educational module to ensure equivalent social contact in both arms of the study. After the 6-months, participants will receive the same intervention as the intervention arm.
