Studying the reliability of a wearable device to monitor sleep quality in young children with Rett syndrome

Principal Investigator: Sarika Peters, Ph.D.


This is a two-part study, with the second part being optional.

The first part of the study involves:

  • An in-person clinical evaluation at VUMC, during which your child will be fitted for an E4 watch. This device measures movement, heart rate variability, and skin temperature.
  • The child will wear this watch for 6 nights/7 days after the evaluation.

The optional second part of the study involves an overnight stay at the VUMC Sleep Clinic (located inside the Nashville Marriott at Vanderbilt), during which your child will participate in a monitored sleep study while wearing the E4 watch. Parents will stay with their child in the hotel room during the sleep study.

Participant Criteria

Females ages 4-18 with Rett syndrome


Participants will be compensated with $75 for completing the first part and $125 for completing the second part. Parents will also receive a report of results from the sleep study.
