Three clinical trials studying transcutaneous vagus nerve stimulation (tVNS) are listed as recruiting, according to trial summaries. tVNS delivers non‑invasive electrical stimulation of the vagus nerve through the ear.

One trial tests a small ear device paired with computer‑based speech therapy for people with aphasia after chronic stroke. The study aims to measure changes in word‑finding and to assess whether the ear device is safe and practical for home use.

A second study combines a form of neuromodulation with structured mindfulness and a relapse‑prevention program for patients with alcohol dependence. The trial will evaluate whether adding stimulation plus mindfulness improves outcomes of the relapse‑prevention intervention.

The third study examines tolerability and feasibility of tVNS in patients following aneurysmal subarachnoid haemorrhage (aSAH). Its primary focus is safety and ease of use, and whether the approach is practical in this acute neurological population.

All three entries are marked as recruiting. The publicly available listings provided trial aims and target conditions but did not include sample sizes, locations, or start and end dates in the summary text reviewed here. Interested clinicians and potential participants should consult the individual trial records for eligibility criteria, site locations and contact information.
