Dialing back stiffness may protect muscles in myotonic dystrophy
A study from the University of Rochester Medical Center suggests that muscle stiffness, or myotonia, significantly contributes to muscle damage in myotonic dystrophy type 1 (DM1). Researchers found that reducing this stiffness in mouse models led to healthier muscle tissue, offering a potential new therapeutic target.

While scientists have known this widespread disruption contributes to disease, it has remained unclear which changes are most responsible for the progressive muscle weakness and wasting experienced by people living with DM1.
