A component of an interferential electrical stimulation system designed to conduct electrical currents from the system's pulse generator to specific areas of the body typically to treat pain. In interferential treatment it is typical to use two electrical conductors (electrodes) that are attached to the patient's skin at opposite corners of a square along which currents are delivered (e.g., 4000 and 41000 Hz) that interfere at its centre. This results in a beat frequency at the difference between the frequencies and this is used to treat muscle disorders or, at higher frequencies, to relieve pain. This is a reusable device.
