Differences between PEMF & Laser Therapy

Pulsed Electromagnetic Frequency (PEMF) and Low-Level Laser therapies (LLLT) serve similar functions, however, clear differences exist between the two modalities. Here is a look at some of those differences.

The Differences between PEMF and LLLT

PEMF and LLLT both try to increase cellular energy, but they do it in different ways. Here are a few key differences:

  • PEMF can be used for longer periods of time; LLLT may cause an adverse reaction if used too long.
  • PEMF can push energy deeper into the affected area; lasers have a shallow depth.
  • PEMF can offer a full body session; lasers only affect a single point at a time.

These points all make PEMF the superior therapy. PEMF works best for most things, but a doctor may want to use an LLLT modality for a very specific purpose. PEMF can also work in conjunction with LLLT. In fact, PEMF has seen great use as a pre and post LLLT session.

PEMF is an ideal solution for an incredible number of ailments. LLLT, while a little more limited, is also a good choice when applicable. For those who want or need a fuller, safer, and ideal therapy, then PEMF would be the route to go.

Pulsed Electro Magnetic Field Therapy (PEMF)

PEMF sessions involve using pulsing electromagnetic fields. PEMF practitioners direct electromagnetic fields towards areas of a patient’s body that have injuries or other damage. When the energy fields pass painlessly into the cells of the area, those cells absorb that energy. In this way, the electromagnetic fields exercise and energize those cells. That’s why PEMF sessions are often called “cellular exercise.”


That boost to cellular activity helps to rejuvenate the cells, compelling them to help the area heal faster. PEMF cellular exercise can also help the body use nutrients more efficiently. PEMF modalities aid in water absorption and eliminate cell stagnation. Altogether, PEMF helps to rejuvenate cells as well as optimize their overall functionality.

Because of how PEMF works, it has seen widespread use in several areas. Cellular exercise is often used to help with pain and inflammation. PEMF sessions may also aid in increasing range of motion, improving mood, and increase the body’s ability to get restful sleep. Since PEMF optimizes the body’s natural functions, it can serve to increase many bodily processes that slow down due to age, disease, or injury. Studies of all types are ongoing for using PEMF in various ways.

Low-Level Laser Therapies

LLLT is a form of light therapy. LLLT makes use of red and near-infrared light from a laser or LED. The lasers used for these therapies are not like the high-powered lasers used for surgical procedures. LLLT sessions involve low-level laser light to stimulate the energy-producing mitochondria of your cells. The thought is that once the mitochondria produce more energy, it will cause your cells to help heal damage. Some of the possible benefits of LLLT include inflammation reduction and some pain relief. LLLT does help with tissue regeneration, but the process is typically localized to a specific area.

In addition, the light used isn’t safe to look at, nor is the laser safe around the thyroid area. One last caveat concerning LLLT is that some people may experience irritation from the use of the light on one specific area for too long or too often.
