Electroencephalography as a post-stroke assessment method: An updated review. / Electroencefalografía como método de evaluación tras un ictus. Una revisión actualizada.

Given that stroke is currently a serious problem in the population, employing more reliable and objective techniques for determining diagnosis and prognosis is necessary in order to enable effective clinical decision-making. EEG is a simple, low-cost, non-invasive tool that can provide information about the changes occurring in the cerebral cortex during the recovery process after stroke. EEG provides data on the evolution of cortical activation patterns which can be used to establish a prognosis geared toward harnessing each patient's full potential. This strategy can be used to prevent compensation and maladaptive plasticity, redirect treatments, and develop new interventions that will let stroke patients reach their new maximum motor levels.

Análisis del movimiento de la extremidad superior hemiparética en pacientes con accidente cerebrovascular: estudio piloto / Movement analysis of upper extremity hemiparesis in patients with cerebrovascular disease: a pilot study

Introducción: Consecuentemente a la lesión neurofisiológica, los pacientes con ictus presentan limitaciones motoras principalmente en el hemicuerpo contralateral al hemisferio lesionado. El objetivo de este trabajo es cuantificar las estrategias motoras de compensación que ocurren en la extremidad superior afectada en pacientes con ictus durante la actividad de beber agua de un vaso.Material y métodos: Cuatro pacientes con ictus y cuatro sujetos controles, sin patología y diestros. El análisis del movimiento se realizó usando el sistema VICONmotion System® y el equipo de electromiografía de superficie Aurion ZeroWire®. Se analizaron los movimientos articulares del codo, el hombro y el tórax. Se realizó un análisis cualitativo de la secuencia de activación muscular. Resultados: Se observó una disminución de las amplitudes articulares en el plano sagital del codo y el hombro durante la actividad de beber en el grupo de casos; sin embargo, las amplitudes articulares del tronco y el hombro en el plano frontal fueron mayores con respecto a los sujetos controles. En cuanto a la secuencia de activación muscular, deltoides anterior, medio y posterior, se contrajeron en el grupo de pacientes conjuntamente durante la tarea, mientras que el trapecio superior mantuvo su activación durante toda la actividad. Conclusiones: El análisis cuantitativo del movimiento ofrece información cuantitativa acerca de las estrategias de compensación que realizan los pacientes con ictus, y por tanto, su relevancia clínica es importante (AU)

Introduction: As a result of neurophysiological injury, stroke patients have mobility limitations, mainly on the side of the body contralateral to the lesioned hemisphere. The purpose of this study is to quantify motor compensation strategies in stroke patients during the activity of drinking water from a glass. Material and methods: Four male patient with cerebrovascular disease and four right-handed, healthy male control subjects. The motion analysis was conducted using the Vicon Motion System® and surface electromyography equipment ZeroWire Aurion®. We analysed elbow, shoulder and trunk joint movements and performed a qualitative analysis of the sequence of muscle activation. Results: Trunk, shoulder and elbow movements measured in the stroke patient along the sagittal plane decreased during the drinking from a glass activity, while the movements in the shoulder in the coronal plane and trunk increased. As for the sequence of muscle activation, anterior, middle and posterior deltoid all contracted in the patient group during the task, while the upper trapezius activation remained throughout the activity. Conclusions: Quantitative analysis of movement provides quantitative information on compensation strategies used by stroke patients, and is therefore, clinically relevant (AU)
