In the mid-sixteenth century, William Gilbert made the first clear distinction between electricity and magnetism and his contemporary Roger Bacon proposed a general theory of magnetism as a force acting at a distance. Their work mark

Methoden der diagnostischen Hämatologie Stephan Gray demonstrated that electricity could be conducted over a distance. Gray’s “flying boy” experiments started a trend of electrifying human subjects for public entertainment that ultimately led to early electrotherapy. The Leyden jar provided the first simple way to store electricity for b

Thalerd that electricity represented the long sought-after “animal spirits” carried in nerves to control body functions while Volta, after initially agreeing with Galvani, changed his mind and became a critic of Galvani’s work. In the process Volta discovered the electric pile, a major step in the use of

Methoden der diagnostischen Hämatologieas proportional to the amount of current was pivotal in the history of electricity. Based on the discovery Ampere made a quantitative electrometer that he called a galvanometer and Ohm developed his famous eq. I=V/R relating current (I) to the voltage (V) and resistance (R) in an electrical circuit.

W. Hilbe,W. Eisterer,H. Huber,J. Thalernd America were electrotherapists. Since electricity stimulated nerves, nerve cells, and muscle cells, it seemed logical that electrotherapy was most useful for treating neurological diseases. Hospitals set up special areas to house the electronic equipment along with electricians to maintain the eq
