Physical Activity in Persons Newly Diagnosed With Multiple Sclerosis

This single group pre-post pilot intervention will examine the feasibility and initial effect of a 12-week behavioral intervention, based on the Behavior Change Wheel and Capability-Opportunity-Motivation-Behavior (COM-B) model and remotely delivered through electronic newsletters and online one-on-one video conferencing, for promoting physical activity and secondarily reducing fatigue and quality of life in persons newly diagnosed with MS (diagnosed with MS within the past 2 years). The investigators hypothesize the proposed 12-week intervention will be feasible based on process, resource, management, and scientific outcomes. The investigators further hypothesize that individuals who receive the 12-week intervention will demonstrate an increase in physical activity behavior, particularly daily step counts, and reduce fatigue.
