Project Description
Summary:
View help for Summary
Veterans with posttraumatic stress symptoms exhibit reduced
heart rate variability characteristic of autonomic nervous system
dysregulation. Studies show heart rate
variability biofeedback is effective in reducing combat-related posttraumatic stress
symptoms by improving autonomic functioning.
In this pilot study, a wait list comparison group who received a
necessary but insufficient component of the intervention (minimal diaphragmatic
breath training) was used to determine if participation in a single-session
heart rate variability biofeedback intervention, reinforced by twice daily
practice for four weeks, could: (a) reduce posttraumatic stress symptoms in
combat veterans (N=12), and (b) yield
an intervention that the veterans would find acceptable. Heart rate variability biofeedback
significantly reduced global posttraumatic stress symptoms, whereas
diaphragmatic breathing in the wait list group did not. Further,
veterans found the approach acceptable, as demonstrated by a high degree of compliance
with prescribed practice, low study attrition, and continued use over
time. Results of this pilot study
warrant further refinement of a protocol utilizing mHealth to treat posttraumatic
stress symptoms in military populations.
