Procedures voor Rat<em&gt; In situ</em&gt; Skeletspier contractiele eigenschappen

We presenteren een protocol om veranderingen in de neuromusculaire functie te beoordelen. Percutane elektrische zenuwstimulatie is een niet-invasieve methode die spierreacties veroorzaakt. Elektrofysiologische en mechanische eigenschappen van deze reacties maken de evaluatie van de neuromusculaire functie mogelijk, van hersenen tot spier (supra-spinaal, spinaal en perifeer niveau).

Bepaling van neuromusculaire functie gebruiken percutane elektrische zenuwstimulatie

We beschrijven een in vivo protocol om dorsiflexie van de voet te meten na stimulatie van de peroneale zenuw en contractie van het anterieure crurale compartiment van de achterpoot van de rat. Dergelijke metingen zijn een onmisbaar translationeel hulpmiddel voor het evalueren van skeletspierpathologie en weefselengineeringbenaderingen voor spierreparatie en -regeneratie.

toepassingen van<em&gt; In Vivo</em&gt; Functioneel testen van de Rat tibialis anterior voor de evaluatie van Tissue Engineered Skeletal Muscle Repair

Evaluatie van motorisch herstel blijft de benchmark uitkomstmaat in experimentele perifere zenuwstudies. De isometrische tetanische krachtmeting van de tibialis voorste spier in de rat is een onschatbaar hulpmiddel om functionele resultaten na reconstructie van ischiaszenuwdefecten te beoordelen. De methoden en nuances worden in dit artikel beschreven.

Maximale isometrische tetanische krachtmeting van de Tibialis-voorste spier in de rat

Kwantificering van de maximale kracht van de knie-extensor is noodzakelijk om functionele aanpassingen aan veroudering, ziekte, letsel en revalidatie te begrijpen. We presenteren een nieuwe methode om herhaaldelijk in vivo knie-extensie isometrisch piek tetanisch koppel te meten.

Het huidige protocol beschrijft beknopte experimentele details over de evaluatie en interpretatie van in vivo koppelgegevens verkregen via elektrische stimulatie van de gemeenschappelijke peroneuszenuw bij verdoofde varkens.

Dit artikel beschrijft de methodologie voor het nabootsen van in vivo spierkrachtproductie tijdens ex vivo werklusexperimenten met behulp van een "avatar"-spier van een laboratoriumknaagdier om de bijdragen van spanningstransienten en activering aan het spierkrachtrespons te beoordelen.

"Avatar", een gewijzigd Ex vivo werklusexperiment met In vivo spanning en activering

Dit protocol presenteert een testsysteem dat wordt gebruikt om kwantificeerbare en gecontroleerde vermoeidheidsblessures in een achillespees van een rat te induceren voor een in-vivo model van door overbelasting geïnduceerde tendinopathie. De procedure bestaat uit het vastzetten van de enkel van de rat aan een gewrichtsactuator die passieve enkeldorsaalflexie uitvoert met een op maat geschreven MATLAB-script.
