Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Low resting Heart Rate Variability (HRV)-- the variability in the time in between heart beats--is a physiological indicator of stress and has been associated with reductions in wellbeing and increases in all-cause mortality. Higher heart rate variability is associated with better sleep quality while lower heart rate variability is associated with increased chronic inflammation. The negative effects of PTSD on sleep are well-documented, and interventions are often targeted at alleviating this damaging consequence, as insufficient sleep can perpetuate anxiety and impair day-to-day functioning, leading to an overall reduced quality of life.
The current standard of care is to offer a combination of trauma-focused psychotherapy and symptom-focused medications, typically a selective serotonin reuptake inhibitor medication. However, a promising treatment known as the Stellate Ganglion Block (SGB) plus the Superior Cervical Ganglion Block (SCGB) procedure has been shown to alleviate PTSD symptoms without any of the side-effects and barriers known to patients on conventional treatments. While this treatment shows promise, most of the research performed so far has used subjective self-report measures of sleep quality and stress. Whoop biometric capture devices offer an opportunity to objectively measure sleep quality and heart rate variability to investigate the effects of the SGB. Physiological data could reveal whether this treatment works not just to alleviate subjective stress, but to physically reduce the effects of PTSD on the body.

People who suffer from PTSD
The sample will be composed of 30 patients from Stella's Chicago practice: 712 N Dearborn St, Chicago, Illinois 60654
stellate ganglion block (SGB)
The protocol for the SGB plus SCGB will be followed, wherein participants are given right-side procedures followed by left-side procedures on a different day if no initial improvement is seen. This procedure is carried out by injecting a local anesthetic into the neck to target the Stellate Ganglion and Superior Cervical Ganglion nerve bundles.
