El cient\u00edfico franc\u00e9s Gr\u00e9goire Courtine desarrolla intervenciones terap\u00e9uticas basadas en neurorrehabilitaci\u00f3n, neuropr\u00f3tesis
y rob\u00f3tica para reparar lesiones de la m\u00e9dula espinal y otros trastornos neuromotores, por lo que ha sido reconocido como laureado de los Premios Rolex a la Iniciativa 2019.<\/span>

Apasionado de la escalada y amante de los deportes extremos, el franc\u00e9s Gr\u00e9goire Courtine, especialista en neurorrehabilitaci\u00f3n de 44 a\u00f1os, ha experimentado much\u00edsimas veces y de primera mano cu\u00e1n importante es el movimiento en la vida. Por ello, este profesor asociado del Centro de Neuroprot\u00e9sica en la Escuela Polit\u00e9cnica Federal de Lausana (EPFL), en Suiza, centra sus esfuerzos desde hace tiempo en el tratamiento de lesiones medulares<\/strong>. Tras pasar a\u00f1os investigando maneras novedosas de revertir esos da\u00f1os, ha logrado un invento revolucionario que ha sido reconocido tambi\u00e9n con un Premio Rolex a la Iniciativa 2019.<\/p>\n\n\n\n

Lo ha hecho desde su start-up<\/em> GTX Medical y se trata de una especie de \u00abpuente electr\u00f3nico\u00bb con el que se hace un bypass en el lugar de la lesi\u00f3n de la columna vertebral, posibilitando que el cerebro de los pacientes con lesiones medulares vuelva a asumir el control de las piernas y permiti\u00e9ndoles caminar.<\/strong> \u00abEs un puente neuroprot\u00e9sico que se implanta entre el cerebro y la m\u00e9dula espinal lumbar del paciente \u2013explica Courtine\u2013. Con ayuda de tecnolog\u00eda inal\u00e1mbrica, este sistema transmite se\u00f1ales desde el cerebro, encargado del control del movimiento voluntario, hasta las piernas a trav\u00e9s de una estimulaci\u00f3n el\u00e9ctrica de la parte inferior de la m\u00e9dula espinal, y contribuye a que los nervios espinales da\u00f1ados se recuperen\u00bb.<\/p>\n\n\n\n

En el auditorio del cuartel general de National Geographic, en Washington D.C., donde Courtine acudi\u00f3 a presentar su proyecto junto a los otros cuatro Laureados Rolex, el cient\u00edfico explic\u00f3 que cuando se ordena que los electrodos env\u00eden se\u00f1ales el\u00e9ctricas a los m\u00fasculos de las piernas (por ejemplo, desde una tablet), estas activan \u00e1reas de la m\u00e9dula que reproducen las se\u00f1ales que el cerebro env\u00eda para caminar. Hasta el momento, ese sistema pionero ha permitido recuperar la capacidad de andar a tres hombres que llevaban paralizados de cintura para abajo m\u00e1s de cuatro a\u00f1os.<\/strong> Tras una semana de sesiones, pudieron ponerse de pie y caminar con andadores, y despu\u00e9s de cinco meses de fisioterapia y de entrenarse con ese puente el\u00e9ctrico, fueron capaces de controlar voluntariamente los m\u00fasculos de sus piernas y andar durante una hora sin agotamiento muscular. Hoy pueden permanecer de pie y avanzar distancias cortas con la ayuda de unas muletas.<\/p>\n\n\n\n

Un aspecto fabuloso de este sistema de estimulaci\u00f3n a trav\u00e9s de electrodos es que, por lo que parece, no solo consigue hacer efectiva la orden cerebral de moverse. Todo indica que la propia estimulaci\u00f3n podr\u00eda estar reconstituyendo las conexiones perdidas entre el cerebro y la m\u00e9dula espinal, algo que a\u00fan est\u00e1 por probarse pero que ser\u00eda realmente sensacional.<\/strong> Courtine cree que los estimuladores ser\u00e1n m\u00e1s efectivos cuanto m\u00e1s reciente sea la lesi\u00f3n medular, por lo que en su pr\u00f3ximo ensayo cl\u00ednico tratar\u00e1 a tres pacientes que sufren par\u00e1lisis desde hace aproximadamente un a\u00f1o. \u00abSeguir\u00e9 desarrollando un tratamiento para la m\u00e9dula espinal hasta que exista una cura\u00bb, asegura. Sin duda, va por buen camino.<\/a><\/p>\n\n\n\n
