Galvanic current is another name for which category of electrical stimulation?

• A. Direct current
• B. Pulsed current
• C. Alternating current
• D. Capacitive current

Answer: (A)

Galvanic current is a continuous, unidirectional flow of electricity—the defining feature of direct current. In therapeutic electrostimulation, this steady polarity is what characterizes galvanic or DC-type applications (such as iontophoresis or wound healing with a constant field). It differs from pulsed current, which comes in on/off bursts; from alternating current, which reverses direction repeatedly; and from capacitive current, which involves high-frequency AC used with capacitive coupling. So galvanic current corresponds to direct current.
