Stroke Therapy With Brain Oscillation Synchronized Stimulation (STROKEBOSS)

Detailed Description
Stroke is one of the leading cause for long-term disability worldwide. The standard approach to treat deficits after stroke is a rehabilitation therapy, that follows the stroke event directly. This therapy mainly includes physiotherapy and occupational therapy. Yet, despite intensive rehabilitation efforts, more than half of all stroke patients remain greatly disabled.
Repetitive TMS is capable of inducing plasticity-like effects in the brain, that are expected to enhance adaptive plasticity processes leading to functional regain after stroke. In the motor cortex, brain oscillation-synchronized TMS, i.e. TMS triggered dependent on the phase of instantaneous µ-alpha oscillations as detected by real-time EEG (electroencephalography) analysis, has been shown to consistently increase motor cortical excitability and plasticity effects. We therefore hypothesis that a greater therapeutic potential of TMS to modulate dysfunctional brain networks can be exploited by personalizing TMS therapy to individual brain states (i.e. brain oscillations).
This study aims to investigate the effectiveness of an ipsilesional 100 Hz TMS triplet burst protocol synchronized to the ongoing µ-alpha oscillation compared to the current TMS standard therapy of contralesional 1 Hz rTMS in chronic stroke patients. Both groups will undergo stimulation therapy three times a week, with each session directly followed by physiotherapy. Motor recovery will be assessed directly after as well as three months after completion of the therapy.
