- IFT uses medium-frequency electrical currents (usually around 4,000 Hz).
- Two slightly different currents are applied to the body through electrodes placed on the skin.
- Where the two currents meet (interfere), they produce a low-frequency stimulation deep inside the tissues.
🔹 How it works
- Two medium-frequency currents are applied through electrodes.
- Interference occurs inside the body, producing a “beat frequency” (usually 1–250 Hz).
- This low-frequency effect stimulates nerves, muscles, and circulation, without the discomfort of direct low-frequency stimulation.
🔹 Effects and benefits
- Pain relief (by stimulating sensory nerves and blocking pain signals to the brain).
- Improved blood flow and circulation.
- Reduced swelling and inflammation.
- Accelerated healing of tissues after injury or surgery.
🔹 Clinical uses
- Chronic and acute pain conditions (back pain, arthritis, neuralgia).
- Soft tissue injuries (sprains, strains).
- Post-surgical rehabilitation.
- Muscle spasm reduction.
