About this study

Official title: Prognostic Value Assessment of Biomarkers in Acute Lumbar Radiculalgia : Contribution of the Diffusion Tensor in Magnetic Resonance Imaging

Diffusion tensor imaging (DTI) is a non-invasive MRI technique offering a functional approach that provides morphological information about the microstructures of the nerve roots. DTI is a widely used neuroimaging technique and is a current topic of research in the field of peripheral nerve imaging.The aim of the study is to determine the prognostic quality of the DTI parameters to predict the therapeutic evolution of patients with lumbar radiculalgia at 6 months.

What is being measured

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

  1. Predictive performance of DTI imaging on the therapeutic evolution

    DTI is a sensitive probe of cellular structure that works by measuring the diffusion of water molecules. The measured quantity is the diffusion coefficient, a proportionality constant that relates diffusive flux to a concentration gradient and has units of mm2/s.

    The objective is to know if the interpretation of DTI allow to predict the therapeutic evolution of patients. For instance, the patients will need in the future oral drugs? Or they will need rather an infiltration? Or they will need rather a surgery?

    Measured: 6 months

Secondary outcomes (3)
  1. Correlation between DTI parameters and pain intensity

    DTI is a sensitive probe of cellular structure that works by measuring the diffusion of water molecules. The measured quantity is the diffusion coefficient, a proportionality constant that relates diffusive flux to a concentration gradient and has units of mm2/s.

    The intensity of pain will be self evaluated by the visual analogue scale (VAS). This scale is between 0 and 10 (in cms) being absence of pain and 10 intolerable pain.

    Measured: 6 months

  2. Correlation between DTI parameters evolution and neuropathic pain

    DTI is a sensitive probe of cellular structure that works by measuring the diffusion of water molecules. The measured quantity is the diffusion coefficient, a proportionality constant that relates diffusive flux to a concentration gradient and has units of mm2/s.

    The presence of neuropathic pain will be evaluated by the Neuropathic Pain Symptom Inventory (NPSI) scale. This is a self-questionnaire.The tool evaluates mean pain intensity in the last 24h in a verbal numeric scale from zero (no pain) to 10 (worst imaginable pain). Total pain intensity score may be calculated by the sum of 10 descriptors.

    Measured: 6 months

  3. Correlation between DTI parameters evolution and disability

    DTI is a sensitive probe of cellular structure that works by measuring the diffusion of water molecules. The measured quantity is a diffusion coefficient, a proportionality constant that relates diffusive flux to a concentration gradient and has units of mm2/s. The disability will be measured by the Oswestry Disability Index (ODI). The final score/index ranges from 0-100. A score of 0-20 reflects minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled, and 81-100 bed-bound.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing DTI sequence acquisition in people with Lumbar Radiculopathy and Magnetic Resonance Imaging, run by Lille Catholic University at 1 site in France.

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 8 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 26 Mar 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 France. 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?

Results are not available in the source record.

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

Contact Marie Paule LEBITASY, MD, PhD (03.20.22.57.41, Lebitasy.Marie-Paule@ghicl.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive performance of DTI imaging on the therapeutic evolution (time frame: 6 months). 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 26 Mar 2024.
