Osteopathic Manual Therapy (OMT) and Brain Structure and Function in Primary Headache Patients: A Pilot Study

An interventional study of Osteopathic Manipulative Therapy in Primary Headaches (Migraines, Tension, Cluster Headaches), sponsored by Edward Via Virginia College of Osteopathic Medicine. Completed at 1 site in United States. Open to participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-05-06.

Study summary

Chronic headaches are associated with changes in brain structure and function that may be associated with increased suffering and disability. Understanding how Osteopathic Manipulative Therapy (OMT) affects these changes would reveal new insight into how the brain processes pain and returns to normal function. Also, demonstrating these changes would provide evidence regarding how OMT causes a reduction in pain and disability, supporting the recommendation for OMT as a primary treatment option for headaches.

What researchers measure

Primary outcomes

  1. Brain Structural and Functional Changes

    Structural MRI will assess physical changes in brain anatomy, including differences in the size, shape, or density of specific brain regions. For example, changes in gray matter volume or white matter integrity may indicate neuroplasticity changes response to an OMT. Functional MRI (fMRI) will measure brain activity by detecting changes in blood flow within the central pain network. When a specific brain region becomes more active, it requires more oxygen, which fMRI can detect. This will help determine whether the intervention alters brain function, such as increased activation in areas involved in movement, memory, or pain processing. Magnetic Resonance Spectroscopy (MRS), unlike standard MRI, which provides images of brain structures, will analyze chemical changes in the brain. It detects levels of important brain metabolites involved in neural signaling neuronal health.

    Time frame: From enrollment to the end of treatment at 5 weeks

Secondary outcomes

  1. Headache Impact Test - 6 (HIT-6)

    The HIT-6 (Headache Impact Test-6) measures how headaches affect daily life, including pain severity, frequency, and impact on work and social activities.

    Time frame: From enrollment to the end of treatment at 5 weeks

  2. Short Form -36 (SF-36)

    The SF-36 (Short Form-36 Health Survey) is a 36 question survey that assesses overall physical and mental well-being, evaluating factors like physical function, pain, energy levels, and emotional health.

    Time frame: From enrollment to the end of treatment at 5 weeks

  3. Depression Anxiety and Stress Scale 21 (DASS-21)

    The DASS-21 (Depression, Anxiety, and Stress Scale-21) is a 21 question survey that examines emotional well-being by measuring levels of depression, anxiety, and stress.

    Time frame: From enrollment to the end of treatment at 5 weeks

  4. Headache intensity

    Headache intensity will be measured by an 11 point numerical rating scale from 0 (no pain) to 10 (worst possible pain).

    Time frame: From enrollment to the end of treatment at 5 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2025 to primary completion in Oct 2025, 1 month.

Of 309 non-industry interventional studies with no phase under Migraine Disorders, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 36. This study's 1 month is below that.

Counting every sponsor, half of 358 studies reached it within 15 months; a quarter within 7 and three quarters within 34.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
