The investigators predict that decreased heart rate variability and poor sleep quality will be significantly correlated with higher self-reported anxiety following brain injury.
Acute rehabilitation inpatients with moderate-to-severe brain injury will wear biosensors that track total sleep time and heart-rate variability for up to 1 week. During this time the participants will also complete surveys regarding symptoms of anxiety. The investigators hypothesize that decreased heart rate variability and poor sleep quality will be significantly correlated with higher self-reported anxiety following brain injury.
Study Type
OBSERVATIONAL
Enrollment
14
Shirley Ryan Ability Lab
Chicago, Illinois, United States
anxiety
self-reported anxiety survey
Time frame: 48 hours
heart rate variability
Skin biosensor on patient chest, measuring heart rate over 6 minute interval while patient is awake and resting. Then heart rate variability is calculated based on the R-R interval.
Time frame: 48 hours
sleep
self-reported sleep survey. Also skin biosensor measuring heart rate and accelerometer overnight for 2 consecutive nights. Total sleep time and awakening episodes will be derived from the biosensor data.
Time frame: 48 hours
post-traumatic stress disorder (PTSD)
self-reported survey of PTSD symptoms
Time frame: 48 hours
