Clinical Trial Summary

The goal of this clinical trial is to test how exercise affects learning and memory processes relevant to the treatment of PTSD. Participants will complete a baseline intake followed by two experimental sessions. During the first experimental session, participants will undergo an MRI session of imaginal exposure to traumatic memory cues followed by 30-minutes of moderate intensity exercise or low intensity exercise. Participants will complete a second session of imaginal exposure with MRI 24 hours later.

Description:

The proposed project would build on our published pilot data and animal models to demonstrate that moderate intensity physical exercise delivered after exposure therapy engages fear circuitry and enhances the consolidation of therapeutic safety learning, thereby enabling enhanced symptom reduction for PTSD. Adults with PTSD related to interpersonal violence (IPV) exposure would complete an initial session of imaginal exposure to traumatic memory cues adapted for an MRI setting. This would be followed by 30-mins of moderate intensity exercise or low intensity exercise control. Participants would return 24-hrs later to complete a second session of imaginal exposure with MRI.

Primary	Change in participant subjective emotional ratings	Participant anxiety will be measured at baseline and after each imagery trial using a 10-point Likert-type scale with higher scores indicative of more subjective anxiety.	24 hours
Primary	Change in Heart Rate	Participant heart rate will be measured at baseline and after each imagery trial using a Biopac MP160 system	24 hours
Primary	Change in Fear Circuit Blood Oxygen Level-Dependent (BOLD) Response	Blood Oxygen Level-Dependent (BOLD) imaging will be measured during each imagery trial	48 hours
