EMTr inhibidora contralesional para la recuperación de la función del brazo después de un accidente cerebrovascular (ConTRAstroke)

18 de septiembre de 2026 actualizado por: Dr. Alexander Thiel, Thiel, Alexander, M.D.

Plataforma canadiense para ensayos con estimulación cerebral no invasiva: rTMS inhibidora contralesional para la recuperación de la función del brazo después de un accidente cerebrovascular: un ensayo de viabilidad (Canstim: ConTRA-Stroke-F)

The CanStim consensus working group (multidisciplinary team of experts in rTMS from institutions across Canada) developed consensus recommendations for a protocol to deliver rTMS as an adjunct to a standard behavioral intervention to improve functional outcomes after stroke in a national stroke rehabilitation clinical trial. The overall goal of this multi-center feasibility trial is not to demonstrate that rTMS is effective, but to demonstrate that each site can recruit the assigned number of patients within a certain period, perform the stimulation procedure in conjunction with the protocol-specified intervention, complete the therapy protocol and enter complete datasets for each patient into the CanStim database. A secondary aim is to identify potential weaknesses of the consensus protocol that may need to be modified before performing a larger scale trial testing for the efficacy of the intervention. A tertiary goal is to examine sex differences in neurophysiological recovery (motor evoked potential and arm functional movement recovery) after 15 treatment sessions of repetitive transcranial magnetic stimulation (rTMS) and to identify sex and gender-related factors that predict the post-stroke recovery.

Descripción general del estudio

Descripción detallada

Rehabilitation is critical for reducing stroke-related disability. Although intensive physiotherapy improves function after a stroke, the frequency and intensity of therapy in a standard clinical rehabilitation session is insufficient to invoke these changes. Transcranial magnetic stimulation (TMS) is a safe, non-invasive method of stimulating the human brain. Repetitive TMS (rTMS) may have the potential to enhance the brain's ability to re-learn specific functions and reduce the amount of standard therapy required to achieve certain functional gains after stroke. Although two recent multicenter studies have begun to test the benefits of applying rTMS during stroke rehabilitation, large scale clinical trials demonstrating the efficacy of rTMS for post-stroke functional motor recovery are lacking. The use of rTMS interventions in stroke rehabilitation trials has been limited by a lack of consensus regarding the optimal protocol for the clinical application of TMS in stroke populations. The Canadian Platform for Trials in Non-Invasive Brain Stimulation (CanStim) is a national platform that aims to facilitate multicenter clinical trials for non-invasive brain stimulation interventions to augment recovery from stroke. As a first step, CanStim investigators convened a multidisciplinary team of experts in rTMS from institutions across Canada to form the CanStim Consensus Working Group and develop consensus recommendations for a protocol to deliver rTMS as an adjunct to standard therapy in a national stroke rehabilitation clinical trial.

Descripción

  1. Inclusion criteria: patients with first ischemic stroke between 2 weeks and 3 months of stroke onset, patients with both cortical and subcortical infarcts, age between 18 and 90 years, English or French as language of daily use, patients must be able to participate in a standard of care upper extremity therapy program and must be able to perform the GRASP AND should have a minimum deficit that they can improve (e.g., <= 56 on FM UE). For the cognitively impaired patients, we will not exclude those with a higher upper limb mobility function. The patients with cognitive complaints, will only be included if they have a score of <24 on the Montreal Cognitive Assessment (MoCA).
  2. Exclusion criteria: prior symptomatic ischemic or hemorrhagic stroke, severe comprehension deficit that may compromise informed consent or understanding of instructions, contraindications to MRI and/or TMS, neurodegenerative or psychiatric disease, epilepsy, or EEG-documented epileptic discharges, chronic renal or liver failure, life-threatening diseases limiting life expectancy to less than 6 months and auditory or visual deficits that cannot be corrected and might impair testing. We will not exclude patients with higher upper limb mobility function.

Experimental: Active rTMS

Sub-acute stroke patients will be randomized to receive actual rTMS treatment. 1Hz rTMS will be applied over contralesional M1 at an intensity of 120% resting motor threshold once daily for 30 minutes (approximately 1800 pulses) for a total of 15 sessions.

Comparador falso: Sham control

Sub-acute stroke patients randomized to receive sham rTMS. For sham-stimulation, the TMS coil will be placed over the inter-hemispheric fissure at the vertex and stimulation will be performed with low intensity (10% resting motor threshold). This will cause similar skin sensations as real stimulation but will not induce currents in motor relevant areas.

An evaluative measure to assess specific changes in limb function among individuals who sustained cortical damage resulting in hemiplegia. It can assess a patients ability to handle objects differing in size, weight and shape and therefore can be considered to be an arm-specific measure of activity limitation.
