Device for low-frequency electrotherapy in a humid environment

摘要

Disclosed is a novel device for low-frequency electrotherapy wherein a moisture proof variable resistor is used to control the output level of a low-frequency diphasic action potential circuit. The diphasic circuit produces a voltage having a pulse width of 0.1 to 10 seconds and a frequency off 10 to 300 Hertz superimposed on the voltage having a pulse interval of 0.1 to 10 seconds.
