Participants in this study will have already been enrolled in another research study: Combining Stellate Ganglion Block with Prolonged Exposure for PTSD, NCT05889741. The investigators are using a Sleep Profiler, EEG headband to monitor a participants brainwaves while they sleep to see what effects the Stellate Ganglion Block injection has on their sleep. Participants will wear the headband for 3 nights before the injection and then 3 nights after the injection. Participants will also complete self-report questionnaires regarding their sleep prior to the injection and following the injection. Approximately 40 participants will be included in this study. This study is a nested observational study whereby participants in the parent study who elect to participate will have their sleep assessed using the EEG headband device and self-reported sleep measures performed.

Insomnia Severity Index
7-item self-report measure that assesses perceived severity of insomnia. Each item uses a 4-point Likert type scale from 0 to 4. The items sum to produce a total score (range 0 - 28) with a higher score indicating
Nightmare Disorder Index (NDI)
The 5-item NDI evaluates for nightmare disorder in accordance with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria. Items are scored from 0-4 to give a total range between 0-20. Higher scores on the NDI indicate greater nightmare severity.
Split Week Self-Assessment of Sleep Survey (SASS-Y) for Workdays
The Split Week SASS (SASS-Y) is a retrospective measure that assesses sleep parameters similar to a sleep diary including time to bed, number of awakenings, time of final awakening, and time out of bed, etc. The Split Week version asks participants to estimate these parameters based on workdays.
Split Week Self-Assessment of Sleep Survey (SASS-Y) for off Days
The Split Week SASS (SASS-Y) is a retrospective measure that assesses sleep parameters similar to a sleep diary including time to bed, number of awakenings, time of final awakening, and time out of bed, etc. The Split Week version asks participants to estimate these parameters based on days off of work.
