Interferential current (IFC) therapy uses a mild, low-frequency electrical signal to reach deep into sore, inflamed tissue. Small pads are placed on the skin around the area that hurts, and the device sends gentle currents that cross paths beneath the surface. Most patients describe the sensation as a comfortable tingling or light buzzing, never sharp or painful. It is one of the simplest, most relaxing treatments we offer.

How It Helps

Those gentle currents do a few helpful things at once. They interrupt pain signals before they reach the brain, which brings quick relief. They encourage your body to release its own natural pain-relieving chemicals. And they boost circulation to the area, which helps reduce swelling and carries away the inflammation that keeps tissue irritated. For tight, guarded muscles, the current also helps them relax so movement feels easier.

What It Treats

Interferential therapy works well for a wide range of issues, from back pain and neck pain to sciatica, joint pain, muscle strains, and stubborn inflammation after an injury. Dr. Robert Caruso often pairs it with other treatments like chiropractic adjustments, massage, or therapeutic exercise so each visit builds on the last and you feel steady, lasting progress.

What to Expect

A typical session is short and easy. You simply relax while the pads do their work, usually for 10 to 15 minutes. There is no recovery time, no medication, and no discomfort, so you can head right back to your day afterward. As with all our care, Dr. Caruso starts with a thorough evaluation to make sure interferential therapy is the right fit for your body and your goals.
