Un In vivo Modelo de roedores de la contracción inducida por la lesión y la monitorización no invasiva de la recuperación

Este video demuestra los procedimientos quirúrgicos y preparaciones necesarios para estudiar las respuestas contráctiles del músculo gastrocnemio medial de rata in situ. Esta preparación permite la medición de las propiedades contráctiles del músculo esquelético bajo condiciones fisiológicas. El animal se anestesia y el músculo se separa del tejido circundante en su extremo distal. El tendón de Aquiles se conecta a un transductor de fuerza, lo que permite medir la respuesta contráctil del...

Procedimientos para la Rata In situ Propiedades contráctiles del músculo esquelético

Presentamos un protocolo para evaluar los cambios en la función neuromuscular. La estimulación nerviosa eléctrica percutánea es un método no invasivo que evoca respuestas musculares. Las propiedades electrofisiológicas y mecánicas de estas respuestas permiten evaluar la función neuromuscular desde el cerebro hasta el músculo (niveles supraespinal, espinal y periférico).

Evaluación de la función neuromuscular Usando percutánea estimulación nerviosa eléctrica

Describimos un protocolo in vivo para medir la dorsiflexión del pie tras la estimulación del nervio peroneo y la contracción del compartimento crural anterior de la extremidad posterior de la rata. Estas mediciones son una herramienta traslacional indispensable para evaluar la patología del músculo esquelético y los enfoques de ingeniería de tejidos para la reparación y regeneración muscular.

La evaluación de la recuperación del motor sigue siendo la medida del resultado de la referencia en estudios periféricos experimentales del nervio. La medida isométrica de la fuerza tetánica del músculo anterior de tibialis en la rata es una herramienta inestimable para evaluar resultados funcionales después de la reconstrucción de los defectos del nervio ciático. Los métodos y matices se detallan en este artículo.

La cuantificación de la fuerza máxima extensora de la rodilla es imprescindible para comprender las adaptaciones funcionales al envejecimiento, la enfermedad, las lesiones y la rehabilitación. Presentamos un método novedoso para medir repetidamente el par tetánico máximo isométrico de extensión de rodilla in vivo.

Este artículo detalla la metodología para emular la producción de fuerza muscular in vivo durante experimentos de bucle de trabajo ex vivo utilizando un músculo "avatar" de un roedor de laboratorio para evaluar las contribuciones de los transitorios de deformación y la activación a la respuesta de la fuerza muscular.

"Avatar", un experimento modificado de bucle de trabajo ex vivo utilizando cepa y activación in vivo

Este protocolo presenta un sistema de pruebas utilizado para inducir lesiones por fatiga cuantificables y controladas en el tendón de Aquiles de una rata para un modelo in vivo de tendinopatía inducida por uso excesivo. El procedimiento consiste en asegurar el tobillo de la rata a un actuador articular que realiza la dorsiflexión pasiva del tobillo con un script de MATLAB escrito a medida.
