How are the electrodes arranged in Inferential Current Therapy to target an area of pain?

• A. Four electrodes arranged in a criss-cross pattern with the pain area in the middle.
• B. Two electrodes placed on opposite sides of the joint.
• C. Eight electrodes placed around the circumference.
• D. One electrode in the center and a return pad far away.

Answer: (A)

Inferential Current Therapy targets pain by using two medium-frequency currents that intersect inside the tissue to create a low-frequency beat at the painful site. Placing four electrodes in a criss-cross pattern around the area allows the two currents to cross in the middle, concentrating the interference there to produce analgesia while the high carrier frequencies keep skin sensation minimal. Other setups—two electrodes on opposite sides of a joint, many electrodes around the circumference, or a single center electrode with a distant return—don’t produce the same focused interference in the target tissue, so they’re not as effective for targeting the pain area.
