This is an observational data collection study to evaluate the ability of a social media recruitment campaign tied to a participant reported symptom survey and self-administered physical assessment tool to influence undiagnosed participants to seek care for suspected Myasthenia Gravis (MG). Participants with undiagnosed neuromuscular symptoms will be recruited via social media using targeted advertisements. Two assessment tools were developed by the study team: the Impact of Daily Living (IDL) Survey and the MG Exercise Assessment. Both tools were designed using supporting literature, accepted guidelines, and a rigorous review via a panel of neurologist key opinion leaders.


This proposed pilot study has 3 objectives:

  • To measure the engagement and feasibility metrics of the social media campaign,
  • To estimate preliminary measures of validity for the MG Exercise Assessment Tool, and
  • To evaluate the time to diagnosis for any participant who has a confirmed diagnosis of MG after the completion of the study compared to that reported in literature.

About This Study

Adult participants who don't have specific diagnosed neurologic conditions will first be screened for inclusion based on the results of the IDL survey which will query participants on the presence or absence of habits/symptoms characteristic of MG. Those who qualify will complete the MG Exercise Assessment in which participants are provided video instructions to perform a series of 10 physical tests to examine if specific muscle groups undergo inducible fatigue. The results of the MG Exercise Assessment are reviewed by our co-principal investigator (a UCSF affiliated, board-certified neurologist) to determine if participants would benefit further from an in-person neurologist evaluation for MG. Each participant is provided with a report of the neurologist's evaluation. Participants are followed for 1 year through bimonthly communications to determine if and when they followed up with a clinician and if they received a confirmed diagnosis of myasthenia gravis.
