Cranial Electrotherapy Stimulation: Piloting a Road to PTSD Prevention in First Responders

Not Applicable
Conditions
Adults
Interventions
Device: Alpha-Stim AID cranial electrotherapy stimulation
Registration Number
NCT06203717
Lead Sponsor
Butler Hospital
Brief Summary

The goal of this study is to test whether active duty firefighters find it possible and suitable to do cranial electrotherapy stimulation (CES) at home, and test whether CES influences measures of stress. The main questions it aims to answer are:

* is CES feasible and acceptable in a population of firefighters, and

* does CES changes feelings of fatigue, anxiety, and brain connectivity in firefighters.

Participants will

* complete four weeks of CES at home, and

* complete daily assessments of fatigue and anxiety, and maybe asked to

* complete an MRI scan before and after CES, and

* wear a device to measure their heart rate and sleep quality.

Detailed Description

Despite an urgent need for interventions that can prevent the development of posttraumatic stress disorder (PTSD) in firefighter first responders who, due to the nature of their occupation, are at ultrahigh risk for PTSD and its profound consequences, current preventative approaches suffer from low rates of efficacy or difficulties with implementation. Cranial electrotherapy stimulation (CES), a noninvasive brain stimulation technique that is FDA approved for treatment of anxiety, insomnia, and depression, offers substantial promise as a proactive preventative intervention for PTSD because of its hypothesized ability to reestablish homeostasis, a process that becomes dysregulated in individuals who develop PTSD. The proposed study is an administrative supplement that combines the unique strengths and knowledge of a complimentary team of scientists from two distinct Centers of Biomedical Research Excellence to test whether four weeks of CES is feasible and acceptable in firefighters as well as obtain early signal of CES efficacy to change subjective and objective indices of homeostatic functioning to allow a long-term collaboration with the ultimate goal to develop a safe, effective, and easily deployable intervention to prevent PTSD in first responders.

Primary Outcome Measures
NameTimeMethod
Acceptability assessed by number of individuals who complete at least 75% of all cranial electrotherapy stimulation sessions in four weeksDuring and following four weeks of cranial electrotherapy stimulation

Acceptability assessed by number of individuals who complete at least 75% of all cranial electrotherapy stimulation sessions during four weeks (less than 20% attrition in the sample).

Intensity of anxiety assessed by VASDaily throughout four weeks of cranial electrotherapy stimulation

Intensity of anxiety will be assessed once daily using a visual analog scale (VAS) with a 0 (not at all) - 100 (severe) scale.

Number of completed cranial electrotherapy stimulation sessions in four weeksDuring and following four weeks of cranial electrotherapy stimulation

Feasibility assessed by number of completed cranial electrotherapy stimulation sessions over the course of four weeks (feasible is defined as more than 75% of sessions completed).

Secondary Outcome Measures
NameTimeMethod
Intensity of feelings of fatigue assessed by VASDaily throughout four weeks of cranial electrotherapy stimulation

Intensity of subjective fatigue will be assessed once daily using a visual analog scale (VAS) with a 0 (not at all) - 100 (severe) scale.

Structural neural connectivity assessed with magnetic resonance imagingPre and post four weeks of cranial electrotherapy stimulation.

Strength of structural connectivity between thalamus and cortical/subcortical regions will be assessed with magnetic resonance, diffusion tensor imaging

Severity of symptoms of posttraumatic stress disorder as measured with the PTSD Checklist for DMS 5 (PCL-5)Pre and post four weeks of cranial electrotherapy stimulation

Presence and severity of posttraumatic stress disorder symptoms will be assessed before and after four weeks of CES on the PTSD Checklist for DSM-5 (PCL-5). Scale ranges from 0 to 80 with higher scores indicating greater severity of posttraumatic stress disorder symptoms.

Functional resting state connectivity assessed with magnetic resonance imaging connectivityPre and post four weeks of cranial electrotherapy stimulation

Strength of functional resting state connectivity between thalamus and (ventro)medial prefrontal cortex, hippocampus, posterior cingulate cortex, and precuneus will be assessed with functional resting state magnetic resonance imaging.
