Trial summary

Functional neurological disorders (FND) are motor, sensory or cognitive symptoms without an identified lesion. This is a very common reason for consultation in neurology. Transcranial magnetic stimulation (TMS) may be performed in these patients both for diagnostic purposes (in the context of motor evoked potentials)… Read more about this study

About this study

Functional neurological disorders (FND) are motor, sensory or cognitive symptoms without an identified lesion. This is a very common reason for consultation in neurology. Transcranial magnetic stimulation (TMS) may be performed in these patients both for diagnostic purposes (in the context of motor evoked potentials) and for therapeutic purposes. The main objective of the study is to evaluate tolerability of TMS in patients with FND, in particular the pain caused by stimulation and the possible modification of painful or non-painful symptoms generated by this TMS. The secondary objectives are to assess chronic pain symptoms of these patients quantitatively and qualitatively, to assess expectations of these patients with regard to the performed examinations and to assess their expectations regarding magnetic stimulation performed for therapeutic purposes.

Read the detailed description

The investigators have therefore developped a questionnaire that will be submitted to all consecutive patients who meet the inclusion criteria and who have given their consent to participate. This questionnaire will be performed in three phases: 1) a few minutes before the realization of evoked potentials and TMS 2) 10 minutes after evoked potentials and TMS 3) two weeks after evoked potentials and TMS (by telephone).

The data collected will be:

  • Phase 1 (a few minutes before the explorations): Quantitative assessment of pain Brief Pain inventory Characteristics of pain Analgesic treatments already received and respective efficacy Expectation for diagnostic tests (confirmation/exclusion of diagnosis, …) Expectation for TMS performed for therapeutic purposes (partial/complete recovery, motor/pain symptoms, …)
  • Phase 2 (10 minutes after diagnostic explorations and therapeutic TMS): Quantification of pain generated by TMS Quantification of discomfort generated by TMS Change in pain symptoms after TMS Change in motor, sensory or cognitive symptoms after TMS Other side effects of TMS
  • Phase 3 (two weeks after TMS, by telephone): Quantitative assessment of pain Brief Pain inventory Quantification of pain generated by TMS Quantification of discomfort generated by TMS Change in pain symptoms after TMS Change in motor, sensory or cognitive symptoms after TMS Other side effects of TMS

What is being measured

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

  1. Pain intensity experienced during TMS on a 11-point numerical rating scale (NRS) ranging from 0 (no pain) to 10 (worst possible pain)

    Pain intensity experienced during TMS on a 11-point numerical rating scale (NRS) ranging from 0 (no pain) to 10 (worst possible pain)

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

An observational study of Functional Neurological Disorder, run by Explorations Fonctionnelles Avicenne 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 2 inclusion and 1 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 12 Dec 2023. 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain intensity experienced during TMS on a 11-point numerical rating scale (NRS) ranging from 0 (no pain) to 10 (worst possible pain) (time frame: 1 hour). 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 12 Dec 2023.
