  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • male or female sex
  • right-handed

  • male or female sex
Show all 9Show fewer
  • right-handed
  • age 18-64
  • interpersonal violence exposure (e.g., physical/sexual assault).

Who cannot join

  • current substance use disorder (other than alcohol, nicotine, or cannabis)
  • acute suicidality
  • history of bipolar/psychotic disorder
  • changes to or addition of psychiatric medication in the past 4 weeks (6 weeks for fluoxetine)
  • medications that effect neurovascular properties upon which BOLD fMRI capitalizes (e.g., water pills)
  • history of neurological disorders or disease (e.g., traumatic brain injury, epilepsy, seizures)
Show all 25Show fewer
  • loss of consciousness > 10 minutes
  • intellectual disabilities (IQ<70)
  • developmental disorders
  • MRI contraindication (e.g., internal ferromagnetic objects such as electronic devices, surgical implants, shrapnel; see phone screen)
  • claustrophobia or the inability to lie still in a confined space
  • physical disabilities that prohibit task performance (e.g., blindness or deafness)
  • positive pregnancy test
  • cochlear implant
  • an implanted neurostimulator
  • physical disabilities that prohibit task performance (e.g., blindness or deafness)
  • vulnerable populations (i.e., pregnant women, individuals appearing to lack consent capacity, prisoners, individuals unable to read consent materials, individuals in a relationship with study researchers (e.g., friends, family members, significant others)
  • having a history of chest pain during physical activity
  • having a bone, joint, cardiac, or other medical condition that a doctor has said may be worsened by physical activity
  • having asthma
  • responding 'Yes' to any of the seven questions on the Physical Activity Readiness Questionnaire (PAR-Q - administered as part of the Exercise Safety Questions of the phone screen), indicating it is unsafe for the individual to engage in aerobic exercise without physician approval (i.e., potential participant would be eligible to participate if they indicated 'Yes' to one or more of the PAR-Q items provided they obtain a doctor's note indicating it is safe for them to participate in the study)
  • Percutaneous Coronary Intervention or acute myocardial infarction in the last 6 weeks
  • unstable arrhythmias/implanted cardiac defibrillator shocks in the last 3 months
  • any other condition that the PI believes might put the participant at risk.
  • Additionally, due to their effects on image quality, interested individuals with the following may be ineligible to participate per PI's judgement: nonremovable dental implants (e.g., braces or upper permanent retainers) as these will distort the MRI images we collect (note: filings, crowns, and silver or gold teeth are okay); any other condition, medication, or implant that the PI believes would degrade image quality or render data unusable

About this study

This study aims to test whether aerobic exercise performed after fear extinction learning improves cognitive, physiological, and neural indices of extinction recall in a sample of trauma-exposed men and women with and without posttraumatic stress disorder (PTSD). Participants will complete a clinical intake visit (Day 0), followed by a three-day fear conditioning (day 1), fear extinction + activity (day 2), and fear extinction recall (day 3) protocol.

What participants receive

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

  • ExerciseBehavioural

    Participants will complete either a 30-minute bout of light-, moderate-, or high-intensity aerobic exercise at one of the visits.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Skin conductance responses

    SCR data will be collected while participants are completing the cognitive task in the MRI environment.

    Measured: Collected during fear conditioning, fear extinction, and extinction recall task.

  2. Threat expectancy ratings

    Threat expectancy ratings will be collected while participants are completing the cognitive task in the MRI environment.

    Measured: Collected during fear conditioning, fear extinction, and extinction recall task.

  3. Neural activity

    Neural activity will be collected while participants are completing the cognitive task in the MRI environment.

    Measured: Collected during fear conditioning, fear extinction, and extinction recall task.

Questions about this trial

What is this clinical trial studying?

A study testing Exercise in people with PTSD, run by University of Alabama, Tuscaloosa at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 15 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

This study is still under way. Results are not available in the source record yet.

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

Contact Kevin Crombie, PhD (2053482684, kmcrombie@ua.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Skin conductance responses (time frame: Collected during fear conditioning, fear extinction, and extinction recall task.). The study lists 3 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 15 Feb 2024.
