Trial summary

Post-traumatic stress disorder (PTSD) is characterized by physiological changes, some of which are thought to be chronic, while others are observed in response to stressogenic stimuli. A psychiatric diagnosis of PTSD is currently based mainly on non-quantitative elements, such as interviews and subjective impressions. Read more about this study

About this study

Official title: Measuring the Biochemical and Physiological Response to Controlled Stressogenic Stimuli

Post-traumatic stress disorder (PTSD) is characterized by physiological changes, some of which are thought to be chronic, while others are observed in response to stressogenic stimuli. A psychiatric diagnosis of PTSD is currently based mainly on non-quantitative elements, such as interviews and subjective impressions. Discernable patterns of stress-related measures may constitute a physiological and biochemical phenotype characteristic of PTSD, which may serve as a biomarker and support diagnostic decisions, as well as personalized treatment plans.

The current study is aimed at examining the possibility of basing a psychiatric diagnosis by measuring changes in the biochemical phenotype of participants with PTSD. Physiological and biochemical data will be collected from participants with and without PTSD using wearable sensors and adhesive biosensor patches. The data will be collected in two conditions: in a neutral, quiet situation, and during and following exposure to controlled stressogenic stimuli.

Being tested
Stressogenic stimulus, Biobeat smart watch and adhesive biosensor patches.
Medical subject headings
Stress Disorders, Post-Traumatic

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

The record says: status not confirmed, as of the sponsor's last update on 3 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Significant differences between groups - HRV (time frame: 3 hours). The study lists 24 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2019.
