Summary

recoveriX PRO system is a Brain-Computer Interface (BCI) device that combines Motor Imagination (MI), with Functional Electrical Stimulation (FES) and Virtual Reality (VR) as feedback devices. The user wears an electroencephalography (EEG) cap that registers the neural activity during the mental practice. This system allows the user to control the feedback devices (FES +VR) with the MI. The goal of this clinical trial is to know the safety and clinical effectiveness of recoveriX-based treatment for improving gait functions in stroke patients. Researchers will compare the functional results obtained by recoveriX system, to the standard treatment based in FES + VR + MI without monitoring the EEG activity. The questions to answer are: 1. Will stroke patients who undergo recoveriX therapy significantly improve their gait ability? 2. Is the functional improvement (gait speed) achieved with the BCI treatment superior to the standard MI+FES+VR treatment? 3. Is the recoveriX-based therapy as safe as the standard treatment? Participants will have to perform a complete assessment to evaluate their functionality before and after the intervention (motor skills, walking ability, impact of the disease in daily living activities). Patients in the BCI group will receive 25 sessions (3 sessions per week) of BCI training with FES and VR feedback (24 sessions in total). Patients in the control group will receive 25 sessions (3 sessions per week) of FES + VR therapy. Patients in the control group will receive the same instructions as the experimental but will not wear the EEG cap.

Interventions

Type	Name	Description
DEVICE	recoveriX	The intervention utilizes the recoveriX PRO system. This is a neurofeedback therapy device that combines Brain-Computer Interface based motor imagery, functional electrical stimulation (FES), and virtual reality (VR). This approach enables participants to engage in motor imagery exercises while receiving real-time feedback based on neural signals. Participants will complete a total of 25 recoveriX sessions, scheduled at 3 sessions per week, with each session lasting 1 hour.
DEVICE	Control	The participants will train the Motor Imagination (MI) combined with Functional Electrical Stimulation (FES) and Virtual Reality (VR) feedback. Feedback provided to the patients will not be linked to the neural signals. The amount of stimulation delivered by the feedback devices (FES and VR) will be similar to the experimental group.
