#77: Actualización en stiff-knee o rodilla rígida post-ictus

En este episodio, actualizamos la evidencia científica sobre la rodilla rígida post-ictus o stiff-knee, ampliando lo que ya sintetizamos hace varios años en el episodio #48. Indagamos en las sinergias musculares en el stiff-knee y en sus fenotipos, para poder realizar una valoración y tratamiento más específico e individualizado. Referencias del episodio: 1. Brough, L.
