Anxiety, Traumatic Brain Injury

Brief summary
The investigators predict that decreased heart rate variability and poor sleep quality will be significantly correlated with higher self-reported anxiety following brain injury.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| anxiety | 48 hours | self-reported anxiety survey |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| heart rate variability | 48 hours | 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. |
| sleep | 48 hours | 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. |
| post-traumatic stress disorder (PTSD) | 48 hours | self-reported survey of PTSD symptoms |
