Pain Assessment & Transcranial Magnetic Stimulation Tolerability in

Status Recruiting

Clinical 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) 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.

Clinical Trial 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 ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
