What Is PEMF Therapy? A Plain-English Breakdown

PEMF therapy sounds complicated, but the idea is simple. Here's what it is, what a session feels like, and what the research does and doesn't show.

PEMF (pulsed electromagnetic field) therapy uses a device that sends pulsing magnetic fields through your clothes and into the body. Sessions are drug-free and non-invasive, and most people feel light tingling or nothing at all. Research is mostly in knee osteoarthritis, where results are mixed and modest. It's a wellness session, not medical care.

How Does PEMF Work?

A PEMF device runs electric current through a coil. That creates a magnetic field that switches on and off in pulses. The field passes through clothing and skin, so nothing has to touch you directly. Researchers are still working out how, or whether, those pulses change how your body feels. We'd rather tell you that plainly than dress it up.

At our studio we use a MagnaWave PEMF system. You lie on a mat or we place an applicator over the area you want to focus on. Most people feel a light tingling, a gentle pulse, or some warmth. Some feel nothing at all.

What Does the Research Actually Show?

Most PEMF research looks at knee osteoarthritis. The results are mixed and modest. Some reviews report improvements in pain and function. One review found function improved but saw no clear effect on pain or stiffness. A 2026 review found gains that may be too small to matter in daily life, and that depended on timing and device settings. The trials are small, with high risk of bias.

For shoulder impingement, one review found a small, short-term benefit. Outside of those areas, the evidence is thin. So if someone tells you PEMF is proven to fix a long list of problems, be skeptical. That includes us. We cover the knee research in more detail in PEMF and knee osteoarthritis.

What a Session Looks Like at Our Office

At DWT Wellness in Cedar Knolls, NJ, a typical PEMF session lasts 20 to 40 minutes. You stay fully clothed and relax on the mat. There's no prep and no downtime. You get up and go about your day. Sessions are run by our founder, Wendy Graham, a certified MagnaWave PEMF practitioner. Wendy isn't a physician, so she won't diagnose anything. If something is seriously wrong, see your doctor first.

Who Shouldn't Try PEMF?

• Anyone with a pacemaker or other implanted electronic device.
• Anyone who is pregnant.
