Ice-water immersion may aid EMG distinction in this case; leaves open validation in prospective cohorts before clinical adoption.
Does immersion of the hand in ice water for 10 minutes distinguish paramyotonia congenita from myotonia congenita on EMG?
Immersion of the hand in ice water for 10 minutes provides an unambiguous electromyographic distinction between paramyotonia congenita and myotonia congenita.
Nielsen et al. (1982) studied this question.
