The use of vagus nerve stimulation (VSS), one of the examples of neuromodulation therapies, continues to increase in the medical field. Basically, invasive (iVSS) and transcutaneous VSS (tVSS) can be performed. tVSS is more preferred because of its advantages such as easy application, not requiring surgical procedure and having fewer side effects. VSS has long been an approved treatment modality in the treatment of epilepsy and refractory depression. tVSS can be administered from the auricular-auricular or posterior ear region. The vagus nerve (VS) belongs to the parasympathetic branch of the autonomic nervous system and has an effect on vital functions. There are also studies in the literature showing that VS stimulation reduces inflammation. In addition to this effect, the vagus nerve may also show analgesic activity through pain-related pathways. Due to its anti-inflammatory and analgesic effects, VSS has become a new treatment method in diseases in which various inflammatory processes are shown in the etiology such as inflammatory bowel diseases, musculoskeletal system diseases and central nervous system diseases.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Heart Rate Variability | The effectiveness of vagus nerve stimulation, its effect on autonomic nervous system activity was evaluated using heart rate variability. Polar H7 device was used for this. The heart rate was recorded non-invasively over the chest for 5 minutes and the beat-to-beat (R-R) variability was measured with Kubios software. | Baseline and immediately after the intervention |
