What is described by a quadripolar setup?

A quadripolar setup is characterized by two sets of bipolar electrodes arranged in a specific crossing pattern. This configuration allows for a more complex stimulation across a targeted area of tissue, often enhancing the therapeutic effects through interference patterns created by the crossing currents. In comparison, a single bipolar electrode or electrodes of varied sizes would not provide the same differential effect that the quadripolar arrangement achieves. Similarly, placing one electrode on each side of the treatment area does not capture the multidirectional stimulation possible with multiple sets of electrodes. The crossing pattern in a quadripolar setup effectively enhances the interaction between the currents, facilitating greater precision in targeting the treatment area and achieving the desired therapeutic outcomes.
