ECARD, Letícia et al. Changes in cortical interhemispheric coherence produced by functional electrical stimulation (FES). Arq. Neuro-Psiquiatr. [online]. 2007, vol.65, n.2A, pp.327-331. ISSN 0004-282X.  https://doi.org/10.1590/S0004-282X2007000200026.

The aim of the present study was to observe cortical alterations produced by functional electrical stimulation (FES), through quantitative electroencephalography (qEEG). Electrostimulation was performed on the right forearm to stimulate the extension of the index finger. EEG activity was recorded simultaneously. The sample consisted of 45 subjects randomly divided into 3 groups of 15 subjects each. The control group was submitted to 24 blocks of stimulation at a current intensity of zero. Group 1 was submitted to 24 blocks and group 2 to 36 blocks. Interhemispheric coherence between F3-F4, C3-C4 and P3-P4 was assessed through a statistical analysis. Results pointed out to increased coherence values after stimulation.

Palavras-chave : FES; EEG; interhemispheric coherence.
