Which electrical current is best for preventing muscle atrophy during rehabilitation?

• A. Interferential Current
• B. Micro Current
• C. Russian Current
• D. Sensory-Level High-Volt Pulsed Current

Answer: (C)

To prevent muscle atrophy during rehabilitation, you want a current that reliably produces strong, repeatable muscle contractions to recruit motor units and maintain muscle mass. Russian current fits this need because it delivers a medium-frequency carrier (around 2500 Hz) in short bursts at about 50 Hz, producing a tetanic contraction that can be sustained with repeated cycles. This pattern effectively strengthens and preserves muscle tissue during rehab, countering disuse atrophy. Other currents are geared more toward healing or pain modulation rather than producing strong, functional contractions. Interferential current is mainly used for analgesia and edema reduction, microcurrent operates at very low amplitudes for tissue healing with minimal contraction, and sensory-level high-voltage pulsed current provides pain relief at the sensory level and does not elicit significant muscle contraction.
