High Frequency currents are associated with which energy level?

• A. Low energy
• B. High energy
• C. No energy
• D. Moderate energy

Answer: (B)

When thinking about high-frequency currents, what matters is the amount of energy they deliver to tissue. Frequency is the rate at which the current alternates; a higher frequency means more cycles per second, and in biological tissue that results in more energy being deposited as heat. This heating and stimulation is the hallmark of high-frequency currents, even though the current may have low amperage. So they’re associated with a high energy level. If you consider the other possibilities, low energy wouldn’t produce the noticeable heating, no energy would mean no therapeutic effect at all, and moderate energy wouldn’t account for the strong heating and stimulation typical of high-frequency currents.
