Validation of a Brain-Computer Interface for Stroke Neurological Upper Limb Rehabilitation

Validation of a Brain-Computer Interface for Neurorehabilitation With a Randomized Controlled Trial (Validación de Una Interfaz Cerebro-Computadora Para Rehabilitación Neurológica Por Medio de un Ensayo Clínico Controlado y Aleatorizado)

The study's main goal is to determine if clinical and physiological effects of a brain-computer interface intervention for the neurorehabilitation of stroke patients' upper limb are greater than the effects of a sham robotic feedback. For this purpose a randomized controlled trial will be performed to compare somatosensory sham robotic feedback with the same somatosensory feedback controlled with the brain-computer interface output.
