The goal of this interventional study is to understand the contribution of the central components to the manifestation of neuromuscular fatigue in stroke survivors. The study will include adults with a first-ever stroke in the subacute phase.
The main question it aims to answer:
• How does the brain activity contribute to the manifestation of neuromuscular fatigue in stroke survivors?
Researchers will compare stroke participants receiving active vs sham tACS in a single session before the fatiguing contractions to determine whether central changes can influence fatigue onset/progression.
Participants will:
* Perform repeated leg muscle contractions until fatigue while seated in an experimental setup
* Receive either active or sham tACS for 20 minutes before the fatiguing contractions.
* Wear non-invasive sensors to record brain activity (EEG) and muscle activity (EMG) during the task
* Complete the study during a single experimental session in which fatigue-related changes will be measured throughout the task
