Effect of Vagus Nerve Stimulation and Breathing Exercise on the Autonomic Nervous System

In our study, the auricular branch in the pinna was superficially stimulated with a TENS-based vagustim device for non-invasive vagus nerve stimulation. The application was performed in regular sessions with a physiotherapist according to the recorded protocol. This deactivation aimed at modulation of the autonomic nervous system via the vagus nerve.

In the study, the participants who were given deep breathing exercises were taught the correct technique in a semi-sitting position. During the exercises, deep breathing and relaxation periods were applied for certain periods. The respiratory rhythm was arranged as controlled inspiration and expiration. The participants were given an application practice so that they could continue the exercise at home.
