Mechanical and microstructural changes of skeletal muscle following immobilization and/or stroke.

Patient management following a stroke currently represents a medical challenge. The presented study investigates the effect of immobilization on skeletal muscles in short positions after a stroke. A rat model was implemented in order to compare four situations within 14 days including control group, immobilization of one forelimb without stroke, stroke without immobilization and stroke with immobilization of the paretic forelimb.

Influence of experimental conditions on visco-hyperelastic properties of skeletal muscle tissue using a Box-Behnken design.

The Mechanical characterization of skeletal muscles is strongly dependent on numerous experimental design factors. Nevertheless, significant knowledge gaps remain on the characterization of muscle mechanics and a large number of experiments should be implemented to test the influence of a large number of factors. In this study, we propose a design of experiment method (DOE) to study the parameter sensitivity while minimizing the number of tests.

Effect of cryopreservation at -80°C on visco-hyperelastic properties of skeletal muscle tissue.

This paper investigated the effect of cryopreservation at -80°C on mechanical visco-hyperelastic properties of skeletal muscle. For that, both tensile and compression relaxation tests were performed on porcine tissues samples in fibre and cross-fibre directions. Material parameters were identified by using first order Ogden's strain energy function coupled with second order Maxwell's model.
