How can you tell the Difference between Frequency Specific Microcurrent (FSM) and Pulsed Electromagnetic Field Therapy (PEMF)? Does it matter?
As we experience a literal explosion in the popularity and burgeoning mainstream adoption of Frequency Medicine & Frequency Therapies, it can be easy to get overwhelmed. Here's what you need to know about FSM, PEMF, the differences, the similarities, and why it matters.
Be sure to first get up to speed with our former posts:
What is the History of PEMF Therapy?
FSM VS PEMF : MICRO-AMPERE CURRENTS vs MAGNETIC FIELDS
FSM IS A DUAL-CHANNEL FREQUENCY DELIVERED BY MICROCURRENT
Microcurrent, whether frequency-specific or not, has an added benefit that PEMF does not: it donates Electrons.
Frequency Specific Microcurrent is delivered via a ramped square wave in millionths of an ampere, or milliamps. This is subsensory, meaning you can't feel the electrical pulses. Within the microcurrent, two frequencies are emitted, corresponding to a target tissue and a condition. This is what makes Frequency Specific Microcurrent superior to straightforward Microcurrent (that you might receive during a facial with your esthetician).
PEMF IS PULSED-ELECTROMAGNETIC FIELD DELIVERED BY MAGNETIC FIELDS
PEMF is typically also subsensory, meaning you do not feel the field (although some systems do emit fields that are either combined with infrared light / heat or are dialed up so high that there is a sensation that is emitted from the PEMF coil.
PEMF uses coiled wire with electrical current running through the wire to produce a magnetic field which has a therapeutic effect.
There is a significant difference between PEMF and Frequency Specific PEMF.
Frequency Specific PEMF is more similar to Frequency Specific Microcurrent than it is to standard PEMF.
PEMF typically offers a more user-friendly delivery system with fewer output wires and easier portability than FSM.
Depending on the system, PEMF can be less (or more!) expensive than microcurrent. Consult your prescribing provider for details.
Depending on the system, PEMF can be either Frequency Specific, programmed by your provider and fully customizable or offer pre-programmed protocols that are non-customizable.
Typically, you don't need a prescription from a medical practitioner for PEMF when it is not frequency-specific. In other words, if you don't need an Rx, the frequencies may not have a high level of specificity. Consult your prescribing provider for details.
Depending on the system, PEMF can be single-channel or dual-channel. Some systems can be quad-channel or have up to 8 channels. This enables PEMF systems to have some level of complexity: the frequencies matter, and the ability to customize or program these protocols is an important factor when learning what system is right for you. This is something that your provider should be able to explain to you.
BOTH PEMF AND FSM
Have been demonstrated to increase ATP by up to 500%
Have beneficial cellular-level effects on the body
Help with pain, microcirculation, and inflammation
Have research that backs their use for a variety of applications (scroll back up for a link to the research)
Depending on the model, most have portable delivery systems
Will benefit health, wellness, prevention, and recovery
May or may not depend upon the skill and experience of your prescribing provider for effectiveness
ONE BIG CHALLENGE: IT DEPENDS ON WHICH DEVICE YOU ARE USING
Part of the challenge of answering a question like "what is the difference between FSM & PEMF" is that it depends on which devices you are comparing. Not all PEMF is made equally. In fact, there are so many variations in PEMF Devices that even comparing two relatively similar devices can prove challenging. You can consult the research on PEMF which is quite promising, but will soon find that because the parameters and delivery of PEMF differs in nearly every brand, it is very challenging to compare. When we compare FSM to PEMF, it's like comparing apples to oranges.
SO WHICH IS BETTER: FSM OR PEMF?
The short answer is: yes. Or, in the words of Zen poet Paul Reps, "Each is Best."
Frustrating I know, but it depends on many factors, and this is why it's a good idea to experience both FSM and PEMF in a treatment session so that you and your provider can determine the system that will work best for your body. You might opt for a microcurrent device over PEMF if you are looking for the most optimal cellular energy production. However, if you are using Frequency-Specific PEMF, which delivers at least dual-channel (and sometimes additional) frequencies through a magnetic converter or a magnetic field, and if your prescribing provider incorporates the frequencies believed to target the mitochondria, there is a chance your outcomes will be very similar. We ultimately need a scientific study to be able to measure the exact changes that can occur with the addition of frequencies to PEMF. It is also likely that the outcome depends upon the condition of the mitochondria in the subject being treated. So the best answer: work together with your provider to determine what is best for your unique body.

Clinically, in the vast majority of patients, Dr. Jessie has not noticed a significant enough difference in the frequency specific FSM vs PEMF systems that she uses, as long as there are at least two frequencies being emitted simultaneously; namely: a condition frequency + a target tissue frequency.
THE LEVEL OF CUSTOMIZATION MATTERS
Ultimately, what will help you get the most out of your Frequency Medicine treatments or home unit setup is the level of expertise and comfort level of your provider who helps set you up with your treatment protocol. A skilled practitioner who has treated thousands of patients with frequency specific therapies will be able to hone in on your needs more efficiently. A practitioner who is comfortable making customizations on-the-fly and modify treatments in the moment will be able to get you set up with protocols that are best tailored to your individual body.
QUESTIONS TO ASK A PROSPECTIVE FREQUENCY MEDICINE PRACTITIONER
What's the difference between FSM and PEMF?
How many frequencies does the system / device run at one time?
Have you completed training in Frequency Specific Microcurrent? What level of training have you completed / are you a Certified Practitioner?
Do you utilize pre-written protocols from a Mode Bank or do you customize protocols during treatment sessions? How much customization do you do during the treatment session?
Do you perform Frequency Response Testing?
Do you rely on a bioenergy scanner, your palpation skills, or both?
Have you supported surgeries using your technology?
Have you supported someone with my condition before? What were the outcomes?
Do you prescribe Home Units for your patients? What level of customization do you offer with these units?
