Descrizione del progetto
Un nuovo sistema di controllo per le neuroprotesi
I dispositivi neuroprostetici impiegano elettrodi per interfacciarsi con il sistema nervoso e tentare di ripristinare la perdita di funzione o di movimento. Gli scienziati del progetto Neuroprosthesis-UI, finanziato dall’UE, propongono di sviluppare un’interfaccia utente che consenta alle persone con disabilità degli arti superiori di controllare la neuroprotesi utilizzando le capacità motorie residue. Questa interfaccia comprenderà diversi sensori per catturare la contrazione muscolare e, con l’aiuto dell’apprendimento automatico, decodificherà l’input dell’utente nell’intenzione di movimento. Questo sistema ibrido aiuterà i pazienti con disabilità degli arti superiori, quali lesioni del midollo spinale, ictus e sclerosi multipla, nello svolgimento di attività della vita quotidiana in modo indipendente.
Obiettivo
In this project, I will develop a user interface that will allow persons with upper limb disabilities to control neuroprosthesis using their residual motor skills. This interface will consist of inertial sensors (IMU) and electromyography (EMG) that are capable of capturing movements and muscle contraction that even persons with high tetraplegia still can control. The interface will also be able to learn different inputs, customizing the system for each user. This requires techniques of machine learning, making it flexible and indicated for users with different upper limb disabilities, such as spinal cord injury, stroke and multiple sclerosis. The machine learning techniques will classify the user inputs into desired commands, working as an intention decoder. The interface will be used to control a hybrid upper limb neuroprosthesis based on surface functional electrical stimulation (FES) and a semi passive mechanical orthosis. The system will allow users to perform activities of daily life independently. To my knowledge, such a hybrid system with FES, and controlled by an interface based on IMUs, EMG and machine learning techniques is novel. I will be working with Christine Coste, an expert in neuroprosthesis for disabled persons, and her interdisciplinary team, which consist of engineers and health professionals with vast experience in neurorehabilitation. This fellowship will enable the transfer of knowledge between her team and me through experiments with real patients and mutual training. I can contribute to the team with my expertise in machine learning and control, whereas they have vast access to patients, medical doctors, mechanical designers, electrical stimulators and sensors. This project is going to be an important step in my career as expand my network in Europe, develop my skills as a biomedical engineer and improve my research experience towards becoming a world-leading expert in neurorehabilitation engineering.
