Superficial neurostimulation application, alpha rhythm and clinical effects

Abstract

Introduction

The alpha rhythm (EEG) in prefrontal regions has been related with the emotional equilibrium, predisposition for a positive mood (Urry et al., 2004) and the activation of the approximation system (Davidson and Irwin, 1999). Superficial neurostimulation application (SNSA) provokes an increase of such rhythm in prefrontal and temporal areas (Bardasano et al., 2010).

Aims

To demonstrate that the increase of alpha synchronization is a common factor in the satisfactory evolution of patients with different pathologies.

Methods

Thirty patients with different symptoms (hostility, anxiety, bruxism and obsessive symptoms) received 20 weekly sessions of 45 minutes long using the SNSA.

Materials

–SNSA topology system: it is a machine for superficial stimulation that uses electricity through superficial electrodes which are placed on feet and hands and an electrode over the 7th cervical vertebra;

–digital encephalogram;

–Faraday cage.

Results

The alpha rhythm was incremented in 85% of the cases in anterior regions of the brain, related with the improvement of scale's punctuation.

Conclusion

The alpha rhythm has been showed to be presented in all individuals that improved their symptoms after the application of SNSA (Fig. 1).
