Study Details

To investigate the use of artificial hyperthermia induced by high frequency currents as a therapeutic method for various medical conditions, particularly focusing on safety and clinical effectiveness.

High frequency currents were passed through the body using large block-tin electrodes (28 by 46 to 6...

One hundred treatments were given to 57 patients from February 1930 to August 1931. The artificial h...

Artificial hyperthermia can be carefully and accurately controlled by a standardized procedure well within the scope of the average hospital. The whole body temperature is elevated by the passage of high frequency currents through the trunk by means of large block-tin electrodes. The temperature is maintained at any desired level below 42°C for 5 hours without danger to a patient in ordinary physical condition. The method is effective for treating various conditions including paresis, arthritis, and gonorrheal infections.
