简要总结

Compare the capacity for cerebral plasticity evaluated in electrophysiology before and after the introduction of gabaergic treatment in subacute post-stroke patients with anxiety (Oxazepam), spasticity (Baclofen) or neuropathic pain (Gabapentin).

入选标准

  • Adults aged 18 and over
  • Confirmed diagnosis of ischaemic or haemorrhagic stroke, subacute (defined as 2 weeks to 6 months after stroke).
  • Presence of a non-urgent indication at the introduction of a gabaergic treatment, for which the delay of introduction provided for in the protocol is considered medically acceptable by the investigator.
  • The PGI-S of the symptom associated with the indication is greater than or equal to
  • Sufficient understanding to participate in the study: BDAE > 3 score.
  • Performing an MRI during routine care at the time of stroke diagnosis (allowing neuronavigation)
  • Absence of motor impairment on the non-paretic hand
  • affiliation with a national health insurance system
  • Free, informed and written consent signed by the participant and the investigator (at the latest on the day of inclusion and before any review required by the research).

排除标准

  • Current or recent treatment ( > 7 days) with a gabaergic drug of interest (oxazepam, gabapentin, baclofen)
  • Medical contraindications for the performance of MSDs according to the TMS safety questionnaire in Appendix 3
  • Need to introduce the planned drug immediately: - Oxazepam: severe anxiety or panic attack requiring immediate treatment; severe depressive episode; current suicidal ideation or identified suicide risk; psychological distress considered by the investigator to be incompatible with an observation period of up to 15 days; - Baclofen: severe, painful or rapidly progressive spasticity requiring immediate introduction of systemic drug therapy; - Gabapentin: severe or insufficiently controlled neuropathic pain requiring immediate drug therapy.
  • Contraindication to the planned medicine: - Oxazepam: severe respiratory failure, untreated sleep apnoea syndrome, acute or chronic severe hepatic impairment, myasthenia gravis, hypersensitivity to oxazepam or any of the excipients, galactose intolerance, total lactase deficiency or glucose-galactose malabsorption syndrome; - Baclofen: hypersensitivity to baclofen or any of the excipients, wheat allergy or celiac disease; - Gabapentin: hypersensitivity to gabapentin or any other excipient, galactose intolerance, total lactase deficiency or glucose-galactose malabsorption
  • Presence of a major peripheral neuromuscular disorder (e.g. severe motor neuropathy) making the interpretation of PEM unreliable.
  • Guardianship, curatorship, safeguarding of justice
  • Current or recent treatment ( > 7 days) with any prohibited treatment (benzodiazepine, Z-drug, morphine, pregabalin, sedative antipsychotic or barbiturate).
  • History of neurological disorders other than stroke, for example: neurodegenerative disease, multiple sclerosis, epilepsy, brain tumour, hydrocephalus.
  • History of severe psychiatric conditions, such as schizophrenia or bipolar disorder
  • pregnancy or breast-feeding
  • Presence of dependence on a psychoactive substance
  • Skin disorder in the stimulated hand indicating the placement of electromyographic collection or stimulation electrodes

结局指标

主要结局

Variation (Δ) in the amplitude of the motor evoked potential (MEP) induced by a Paired Associative Stimulation (PAS) protocol, expressed as the percentage change between pre-PAS and post-PAS measurements, assessed at each session

Variation (Δ) in the amplitude of the motor evoked potential (MEP) induced by a Paired Associative Stimulation (PAS) protocol, expressed as the percentage change between pre-PAS and post-PAS measurements, assessed at each session

次要结局

  • Cortical excitability (TMS): resting motor threshold, MEP amplitude and latency, assessed at each session.
  • Motor learning performance: learning effect, rebound, and retention on SRTT and Target Jump tasks, assessed at each session.
  • Safety: spontaneous report on adverse events, assessed at each session
  • Severity of the symptom that led to treatment prescription reported by the patient using the Patient Global Impression of Severity (PGI-S)
