Clinical Trial Summary

The objective of this study was to determine the effects of protocols of repetitive transcranial magnetic stimulation (rTMS) therapy based on the functional reserve of each hemiplegic stroke patient in subacute phase, compared to conventional low-frequency rTMS therapy on contralateral M1. Investigators hypothesized that the functional reserve of each hemiplegic stroke patient will be different, and therefore an appropriate simulating target for rTMS therapy is needed. In addition, this approach could be more effective compared to conventional protocols applied to stroke patients regardless of their severity, predicted mechanism of motor function recovery, or functional reserves.

Clinical Trial Description

rTMS treatment for patients with stroke is traditionally based on interhemispheric interactions. The widely-used traditional rTMS treatment protocol involves inhibitory low-frequency or continuous theta burst stimulation (cTBS) applied over the contralesional hemisphere and excitatory high-frequency stimulation over the ipsilesional hemisphere. However, concerns have arisen regarding the effect of rTMS on motor recovery in stroke patients. Although still subject to debate, a possible reason for the diverse results of rTMS applied to stroke patients is the uniform application protocol to individuals with varying pathologies and functional reserves, aimed at enhancing recovery. Therefore, this study was aimed to determine the effects of protocols of rTMS therapy based on the functional reserve of each hemiplegic stroke patient. Based on screening evaluations (TMS-induced motor evoked potential (MEP), diffusion tensor imaging (DTI), MRI), investigators hypothesized that patients could be categorized into three groups: 1) preserved ipsilateral corticospinal tract, 2) preserved ipsilateral alternative corticospinal tract, and 3) no ipsilateral corticospinal tract preserved. For each group, investigators plan to randomly assign patients to experimental and control groups to demonstrate the efficacy of different rTMS protocols based on functional reserves compared to conventional inhibitory rTMS applied to the contralesional primary motor cortex. ;

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.
