In this 2 arm randomized trial, the investigators will compare the preliminary effectiveness of a social incentive-based gamification intervention to increase physical activity relative to a control arm among adults with stroke. All participants will use a Fitbit wearable device to establish a baseline step count, select a step goal increase of 33% to 50% above their baseline and then participate in an 8 week intervention. The gamification arm will be entered into a game with points and levels designed using insights from behavioral economics. They will be asked to select a social support partner who will receive weekly updates on their progress in the game.
In this pilot, randomized controlled trial, the investigators will compare the preliminary effectiveness of a gamification with social incentives 8 week intervention to increase physical activity for adults with stroke.
