Muscle reading

The term "muscle reading" was coined in the 1870s by American neurologist George M. Beard to describe the actions of mentalist J. Randall Brown, an early proponent of the art.

Performers such as J. Randall Brown, Erik Jan Hanussen, Franz Polgar, Kreskin, and Nader Hanna have also used muscle reading successfully in their acts.

In all the cases where the mind-reader is supposed to lead a person to a hidden object, the spectator is guided entirely by an involuntary movement of the subject's muscles.

[6] Kreskin, one of the most accomplished performers of muscle reading in modern times, can tell a driver where to go in a car while a subject holds his wrist (or vice versa).

[8] The technique relies on the assertion that the subject will subconsciously reveal their thoughts through very slight involuntary physical reactions, also known as ideomotor responses.
