Study summary

his study aims to investigate whether Osteopathic Manipulative Treatment (OMT) affects cerebrospinal fluid (CSF) flow and glymphatic clearance in the human brain. CSF plays an important role in brain health by supporting nutrient delivery, waste removal, and pressure regulation. Aging and certain neurological conditions are associated with reduced CSF circulation and impaired brain waste clearance.

Participants will undergo magnetic resonance imaging (MRI) scans before and after a 30-minute OMT session to evaluate changes in CSF flow dynamics and brain physiology. The study will also examine whether age, cognition, sleep quality, physical function, anxiety, and depression are associated with changes in CSF flow following OMT.

The study will enroll healthy adults between 18 and 80 years of age. Data collected from MRI imaging and questionnaires may help improve understanding of the physiological effects of OMT and its potential role in supporting brain health

Read the detailed description

Cerebrospinal fluid (CSF) is essential for normal central nervous system function, contributing to nutrient transport, waste clearance, and regulation of intracranial pressure. Aging is associated with reductions in CSF production, impaired glymphatic clearance, and altered CSF flow dynamics, which may contribute to cognitive decline and neurodegenerative disease processes. Although osteopathic manipulative treatment (OMT) has been proposed to influence fluid dynamics, circulation, autonomic balance, and tissue mobility, the physiological effects of OMT on CSF flow in humans remain poorly understood.

This pilot study will investigate whether OMT alters CSF dynamics and glymphatic-related imaging biomarkers in healthy adults. Thirty healthy participants will be enrolled, including individuals between 18-49 years of age and 50-80 years of age. Participants will complete MRI imaging sessions before and after a standardized 30-minute OMT session.

MRI assessments will include structural brain imaging, diffusion tensor imaging (DTI), and phase contrast MRI techniques to evaluate CSF flow, glymphatic-related diffusion metrics, and brain structural characteristics. Participants will also complete questionnaires assessing cognitive function, physical function, sleep quality, anxiety, and depression.

The study aims to:

  1. Determine whether CSF flow differs with aging.
  2. Determine whether OMT modulates CSF flow dynamics.
  3. Examine relationships between imaging findings and participant-reported cognitive, physical, sleep, and psychological measures.

The results of this study may improve understanding of the mechanistic effects of OMT on brain physiology and provide preliminary data for future studies evaluating OMT-related interventions targeting neurophysiological health.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    OMT Intervention with Pre- and Post-MRI Assessment

    Participants will undergo baseline MRI imaging followed by a 30-minute osteopathic manipulative treatment (OMT) session performed by a licensed osteopathic physician. OMT techniques may include osteopathic cranial manipulative medicine (OCMM), indirect method (IM), articulatory technique (ART), muscle energy technique (MET), facilitated positional release (FPR), tender point high-velocity low-amplitude (TP-HVLA), and myofascial release (MFR), selected based on identified somatic dysfunctions and participant tolerance. Following treatment, participants will undergo repeat MRI imaging to assess changes in cerebrospinal fluid (CSF) flow dynamics and glymphatic-related imaging measures.

    Other: Osteopathic Manipulative Treatment (OMT)

Interventions

  • OtherOsteopathic Manipulative Treatment (OMT)

    This intervention consists of a single 30-minute osteopathic manipulative treatment (OMT) session administered by a licensed osteopathic physician trained in neuromusculoskeletal and osteopathic manipulative medicine. Treatment will be individualized based on findings from an osteopathic structural examination assessing somatic dysfunctions involving the head, spine, pelvis, extremities, and myofascial structures. Standardized OMT techniques may include osteopathic cranial manipulative medicine (OCMM), indirect method (IM), articulatory technique (ART), muscle energy technique (MET), facilitated positional release (FPR), tender point high-velocity low-amplitude (TP-HVLA), and myofascial release (MFR). The intervention is performed between pre- and post-treatment MRI sessions to evaluate acute changes in cerebrospinal fluid (CSF) dynamics and glymphatic-related imaging biomarkers.

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.

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.
