WebMyotonia is de-fined clinically as the occurrence of “delayed relax-ation of muscle after voluntary contraction or per-cussion.”1 Patients with myotonia often complain of muscle stiffness that improves with repeated use of the muscle, the so-called “warm-up phenomenon.” On examination, myotonia may be apparent from
