#79: La denervación en la lesión medular y la estimulación eléctrica

En este episodio, profundizamos en uno de los fenómenos más devastadores pero menos comprendidos en neurorrehabilitación: la denervación muscular tras una lesión medular. A través de una revisión exhaustiva de la literatura científica y de la experiencia clínica, abordamos qué ocurre realmente con los músculos que han perdido su inervación, cómo se transforman con el tiempo y qué posibilidades tenemos para intervenir. Hablamos sobre neurofisiología, degeneración axonal, fases de la denervación, y cómo la estimulación eléctrica —especialmente con pulsos largos— puede modificar el curso degenerativo incluso años después de la lesión. Exploramos también el Proyecto RISE, los protocolos clínicos actuales y las implicaciones terapéuticas reales de aplicar electroestimulación en músculos completamente denervados. Si trabajas en neurorrehabilitación o te interesa la ciencia aplicada a la recuperación funcional, este episodio es para ti. Referencias del episodio: 1. Alberty, M., Mayr, W., & Bersch, I. (2023).
