Neurorehabilitation After Stroke With Interacion Brain Compiter Interfaces (bci)

Many recent publications have investigated Brain Computer Interfaces (BCI) systems as a tool for rehabilitation. These should help to restore upper limb movement, especially in sub-acute and chronic stroke patients. Stroke often prevents full movement but does not prevent thinking about a particular movement. RecoveriX is an innovative BCI for rehabilitation after stroke. Recent research has shown that it is BCI therapy that leads to better results than conventional therapy. Brain Computer Interfaces can be combined with other techniques such as Functional Electrical Stimulation (FES) and Virtual Reality (VR). By combining all of these techniques, BCI allows the user to restore neurological function by stimulating neurological plasticity through enhanced motor imagery (MI) perception in real time while patients perform therapeutic tasks. It measures brain activity through the very act of thinking about movement, delivering feedback and actual movement in humans, helping the patient regain lost motor function. RecoveriX can improve a patient's condition even several years after a stroke and is used for acute, sub-acute and chronic conditions. Research on recoveriX has shown that the system produces a remarkable increase in the motor function of the paretic arm, as assessed by the Fugl-Meyer score. There is also a reduction in spasticity of the wrist and fingers, as assessed by the modified Ashworth scale. Other improvements, such as grip, were also observed in the healthy hand. All functional improvements achieved during BCI therapy were maintained for up to 6 months after the end of the therapy. It was noted that the severity of the stroke, or the stage of stroke, was not related to the functional improvement itself.
