Ta-VNS is a relatively new, and increasingly popular, procedure in which weak electrical signals are applied to the skin of the outer ear. These signals activate a branch of the vagus nerve which in turn activates the brainstem which regulates metabolic activity across many brain areas.

The use of ta-VNS in the treatment of depression, anxiety, upper limb disorder after stroke, headache and insomnia is based on detailed evidence drawn from peer-reviewed, published scientific investigations. Many of these publications can be found online and we can guide you to relevant papers if helpful. As with GVS, over the last few years there has been a rapid proliferation of clinical trials demonstrating the therapeutic potential of ta-VNS.

The electrodes used to stimulate the outer ear are much smaller than those used for tDCS and GVS, and the electric currents are often smaller too. The procedure is well-tolerated and much safer and cheaper than the traditional form of vagus nerve stimulation which involves surgical implantation. Some studies report no side effects at all while others highlight infrequent and temporary skin irritation, headache and dizziness. A member of our therapy team will talk to you about these possible side-effects.
