Read our Multiple Sclerosis research guide →FIDO is a research study designed to better understand fatigue — one of the most disabling symptoms in multiple sclerosis and long COVID — by using wearable devices and smartphone-based tests you can use at home. Instead of relying only on clinic questionnaires filled out once, this study continuously tracks how your energy, movement, and thinking patterns change throughout your day over an 8-week period. The goal is to see whether these digital tools can capture fatigue the way you actually experience it in real life.
Fatigue in MS and long COVID is poorly understood because current clinic-based assessments miss how it changes from day to day and how it gets worse after physical activity. This study aims to develop better ways to measure and understand fatigue so doctors can eventually treat it more effectively.

You will have two in-person visits — one at the start and one after 8 weeks — where you complete questionnaires and brief health assessments. Between these visits, you wear two small wearable devices continuously and use a smartphone app to complete short cognitive and physical performance tests several times a week while going about your normal life at home. The study collects information about your movement, sleep, heart rate patterns, and how your thinking and energy change day-to-day.
