Research on the Effectiveness of Neurorehabilitation After Stroke

Официальное название

A Study of Neurorehabilitation Based on Robotics, Brain-Computer Interface (BCI) and Virtual Reality (VR) in Patients with Upper Limb Paresis Due to Stroke in the Early Rehabilitation Period

Обзор

This clinical trial aims to investigate the effectiveness of a novel neurorehabilitation technology for treating stroke in adults. The study will evaluate a simulator that combines robotic orthosis, a non-invasive brain-computer interface (BCI), and a virtual reality (VR) display. The goal of this trial is to advance stroke rehabilitation by exploring the potential benefits of these cutting-edge technologies. Key Research Questions: Efficacy: Does the new simulator significantly improve arm function compared to standard rehabilitation techniques? BCI Technology: Which approach - motor imagery of only the paretic arm or both the paretic and healthy arm - yields greater functional improvements? VR Contribution: How does the integration of VR enhance rehabilitation outcomes? Safety and Tolerability: What potential side effects or adverse events may arise from using the new simulator? Participants who have suffered a stroke will undergo a standard rehabilitation course, during which 10-12 sessions will take place using the innovative simulator: a robotic device moves a patient's paralyzed arm at the command of a non-invasive brain-computer interface to perform a game task resembling real-life activities, augmented by a virtual reality display. Researchers will assess the impact of the new technology on arm function to determine its efficacy in promoting recovery.

Вмешательства

• Устройство Neurorehabilitation simulator
  The participant must complete a mental task - imagine the movement of his arm. If successful, the robotic simulator moves the paralyzed limb.
• Процедура Standard course
  The participant receives a standard course of intervention as prescribed by the attending physician in accordance
