Key result
Dexamethasone treatment for 10 days significantly reduced muscle stiffness (627.3 vs 758.6 N/m) and elasticity, and increased tone, alongside reductions in titin and nebulin content.
Why the study?
Does dexamethasone alter viscoelastic properties and cytoskeletal protein content in rat skeletal muscle?
Does dexamethasone alter viscoelastic properties and cytoskeletal protein content in rat skeletal muscle?
Answers are grounded in this paper and cite their sources.
Dexamethasone-induced skeletal muscle atrophy in rats is associated with altered viscoelastic properties and changes in cytoskeletal proteins, providing insight for rehabilitation practices.

Aru et al. (2013) studied glucocorticoid-induced muscle atrophy (n=16). Dexamethasone vs. 0.15 M NaCl was evaluated on Muscle stiffness (N/m) (p=<0.05). Dexamethasone treatment for 10 days significantly reduced muscle stiffness (627.3 vs 758.6 N/m) and elasticity, and increased tone, alongside reductions in titin and nebulin content.
