There are no generally accepted values for transcutaneous vagus nerve stimulation (taVSS application parameters (amplitude, frequency, intensity, duration, side) yet, therefore there are heterogeneous applications in studies. Although positive effects have been shown in different neurological, psychiatric and musculoskeletal diseases, taVSS treatment is not available yet. It is not clear which parameters are important in patient selection.In this study, it was aimed to investigate the change of taVSS effect in healthy individuals according to the level of autonomic nervous system activity before stimulation.
