Here’s an example of how a clinical research team used hypothesis-driven research methods to discover HRV (Heart Rate Variability) associations with stress disorder symptoms in Marines. VivoSense® software was used to analyze the data collected, ensuring that unusable artifactual data was removed to allow for more accurate findings.
The Marine Resiliency Study Team at the UC San Diego Department of Psychiatry conducted a study to understand how HRV is lowered under combat conditions and the possible relationship to PTSD (Post Traumatic Stress Disorder). The study aimed to assess the relationship between PTSD and HRV while accounting for characteristics of PTSD and HRV such as Traumatic Brain Injury (TBI) and depression. The team hypothesized that lower HRV would be associated with a PTSD diagnosis even when TBI was accounted for and that the co-occurrence of depressive symptoms and PTSD would result in lower HRV than PTSD alone.
