Efficacy of Trans-auricular Vagus Nerve Stimulation on Upper Extremity Motor Recovery in Stroke Survivors

Protocol uses a 25 Hz frequency with 500 μs pulse width in biphasic configuration, operating at a 1:1 duty cycle with current intensity set to the maximum tolerable level without inducing pain. The total stimulation duration is 60 minutes. The stimulation is combined with physical therapy focused on upper extremity function.
