when was the link between muscular contraction and electricity discovered
Muscle contraction In 1780, Luigi Galvani discovered that the muscles of dead frogs' legs twitched when struck by an electrical spark.[39] This was one of the first forays into the study of bioelectricity, a field that still studies the electrical patterns and signals in tissues such as nerves and muscles.

Hysterical strength Extreme strength may occur during excited delirium.[2][3]
