Combined taVNS and tDCS in Subacute Stroke Patients
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Ischemic Stroke
In brief
Ischemic stroke, the most prevalent neurological disorder, is treated with medication and thrombectomy but with limited success, especially in chronic stages where traditional rehabilitation is the primary option. Stroke often leads to post-stroke autonomic imbalance, deteriorating functional outcomes and increasing recurrence risk. Emerging non-pharmacological treatments like Transcutaneous Auricular Vagus Nerve Stimulation (VNS) and Focused Transcranial Direct Current Stimulation (tDCS) offer new possibilities. VNS targets post-stroke tissue injury and promotes healing and neurogenesis, while tDCS aims to enhance motor learning by rebalancing brain activity. Both therapies seek to improve outcomes in both acute and chronic stroke stages.
