Hysterical strength

The name refers to hysteria, a nosological category that included bouts of superhuman strength as one of the possible symptoms, but in Europe this had also been an attribution in previous cases of alleged demonic possession.

[3][4][5] Charcot imputed to the phase of hysterical attacks called clownism the presence of strength and agility not consistent with the age and sex of the person, which before in the Catholic ritual of exorcism was attributed to demonic force.

[5] During that period in the 19th century, the term hysterical strength could also be found in the intersection of such fields, scientific and religious, for instance appearing in a statement by a physician for the Society for Psychical Research.

[9][10] The most common anecdotal examples based on hearsay are of parents lifting vehicles to rescue their children, and when people are in life-and-death situations.

Periods of increased strength are short-lived, usually no longer than a few minutes, and might lead to muscle injuries and exhaustion later.
