myotonic

Involving prolonged contraction

Myotonic describes a condition involving myotonia—prolonged muscle contraction with delayed relaxation.

Someone with a myotonic disorder may grip something and find their hand slow to release.

Myotonic dystrophy is a progressive genetic disease affecting muscles throughout the body.

The term appears almost exclusively in medical contexts.
