Which category of electrical stimulation uses a continuous, non-pulsed current?

Which category of electrical stimulation uses a continuous, non-pulsed current?

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

Answer: (A)

Direct current provides a steady, unidirectional flow of electricity, staying constant in amplitude without pulsing or reversing direction. That means the current is continuous and non-pulsed throughout treatment. Pulsed current delivers current in bursts with off-times, so it’s not continuous. Alternating current reverses direction periodically, so it’s not a single, unidirectional flow. Intermittent current also includes on/off cycles, breaking continuity. Therefore, the category that uses a continuous, non-pulsed current is direct current.
