Anaphoresis is the process of infusing an alkaline (negative) product into tissues from which pole toward which pole?

• A. From the negative pole toward the positive pole
• B. From the positive pole toward the negative pole
• C. Across the skin without regard to polarity
• D. From the neutral pole toward the charged pole

Answer: (A)

Anaphoresis uses an electrical current to drive ions into tissues, so the direction is determined by the ion’s charge and the electrode polarity. An alkaline product contains negative ions, and in galvanic therapy those negative ions are repelled by the negative electrode and move toward the positive electrode. That means the infusion path is from the negative pole toward the positive pole, pushing the alkaline ions into deeper tissues along the current. The opposite process would occur for acidic, positively charged ions, moving from the positive pole toward the negative pole.
