Efficacy of Trans-auricular Vagus Nerve Stimulation on Upper Extremity Motor Recovery in Stroke Survivors
Trial Parameters
Brief Summary
The aim of this clinical trial is to determine if trans-auricular vagus nerve stimulation (taVNS) is effective in improving upper extremity function in stroke survivors. The primary objectives include: Investigating whether taVNS improves motor function in stroke survivors. The secondary objectives include: Assessing any potential side effects associated with the method. Investigating taVNS effects on daily routine functions and spasticity Researchers will conduct a comparative analysis between taVNS and a sham procedure (which mimics the stimulation without any actual effect) to assess its effectiveness. Participants in the trial will: Undergo taVNS combined with physical therapy or a sham procedure with physical therapy daily over a two-week period.
Eligibility Criteria
Inclusion Criteria: Patients aged between 18 and 75 years, with motor impairment in the upper extremity caused by unilateral ischemic or hemorrhagic stroke with stroke onset within the last five years. Exclusion Criteria: * Patients with any contraindication to taVNS, peripheral upper extremity injuries, use of medication affecting cortical excitability in the past 3 months, use of botulinum toxin in the past 3 months, presence of any other neurological disorder, or significant cognitive deficits.
