“…Nonetheless, to the best of our knowledge, there is only a limited number of this type of studies involving children with CP. Furthermore, given the aforementioned difficulties concerning their MI capability, it becomes essential to initially tackle the problem by exploring whether such patients can exhibit the expected response for MI in the form of contralateral event-related desynchronizations (ERDs), usually established as the "gold standard" for the MI response that can be detected with EEG [25][26][27], and frequently the measure of interest in EEG-NFBT MI-based applications (e.g., [23,28,29]).…”

Reorganization of Resting-State EEG Functional Connectivity Patterns in Children with Cerebral Palsy Following a Motor Imagery Virtual-Reality Intervention

Motor imagery (MI) has been suggested to provide additional benefits when included in more traditional approaches of physical therapy for children with cerebral palsy (CP). Regardless, little is understood about the underlying neurological substrates that might justify its supposed benefits. In this work, we studied resting-state (RS) electroencephalography (EEG) recordings of five children with CP that underwent a MI virtual-reality (VR) intervention. Our aim was to explore functional connectivity (FC) patterns alterations following this intervention through the formalism of graph theory, performing both group and subject-specific analyses. We found that FC patterns were more consistent across subjects prior to the MI-VR intervention, shifting along the anterior-posterior axis, post-intervention, for the β and γ bands. Additionally, group FC patterns were not found for the α range. Furthermore, intra-subject analyses reinforced the existence of large inter-subject variability and the need for a careful exploration of individual pattern alterations. Such patterns also hinted at a dependency between short-term functional plasticity mechanisms and the EEG frequency bands. Although our sample size is small, we provide a longitudinal analysis framework that can be replicated in future studies, especially at the group level, and whose foundation can be easily extended to verify the validity of our hypotheses.

“…In that study, eight subjects were randomly separated into two groups: sham and active tDCS. Results showed that for the active tDCS group, the central electrodes Cz, C3 and C4 had the highest volume of epochs with significant values of partial directed coherence (PDC) for alpha (8)(9)(10)(11)(12) and beta (13-30 Hz) frequency bands. The current research expands that work to four new subjects, detailing the nature of the inflow and outflow interactions that show a different behavior for the rest and imagine periods in a repetitive way for all the subjects in a group.…”

“…Their applications can allow a person to interact with a computer by only using their brain activity, [3][4][5] or help impaired people during physical rehabilitation and assistance. [6][7][8] The first evidence of EEG patterns related to movement was detected in 1965, 9 showing a slow negative EEG activity preceeding self-initiated movement by low potentials. 10,11 In 1994, 12 the relationship with event synchronization over motor areas was studied.…”

The use of transcranial direct current stimulation (tDCS) has been related to the improvement of motor and learning tasks. The current research studies the effects of an asymmetric tDCS setup over brain connectivity, when the subject is performing a motor imagery (MI) task during five consecutive days. A brain–computer interface (BCI) based on electroencephalography is simulated in offline analysis to study the effect that tDCS has over different electrode configurations for the BCI. This way, the BCI performance is used as a validation index of the effect of the tDCS setup by the analysis of the classifier accuracy of the experimental sessions. In addition, the relationship between the brain connectivity and the BCI accuracy performance is analyzed. Results indicate that tDCS group, in comparison to the placebo sham group, shows a higher significant number of connectivity interactions in the motor electrodes during MI tasks and an increasing BCI accuracy over the days. However, the asymmetric tDCS setup does not improve the BCI performance of the electrodes in the intended hemisphere.

Debido a la falta de autonomía y a la dificultad en las interacciones sociales, las personas con discapacidades físicas, generalmente sufren de una calidad de vida disminuida. El siguiente documento describe el desarrollo de una plataforma móvil de bajo costo capaz de asistir a las personas con severas discapacidades motoras en diferentes interacciones sociales. La plataforma requiere una base móvil inalámbrica; adaptando dos dispositivos, una cámara y un rastreador ocular; adicionalmente se requiere un software que permite integrar todos los componentes para elaborar una aplicación fácil de usar. Luego, para validar la operación de la plataforma se realizaron varias pruebas, usando una metodología de medición de usabilidad, con diferentes usuarios dentro de un cierto rango de edad, con y sin discapacidades. En consecuencia, como primera instancia de validación, la plataforma de bajo costo cumple con la función esperada para la asistencia de interacción social de personas con discapacidad. Finalmente, al ser un diseño abierto y verificado su funcionamiento, toda la información necesaria para la construcción del aparato es de libre acceso, a través de la página electrónica del proyecto.
