Extracorporeal Magnetotransduction Therapy, or EMTT, is one of the newest drug-free technologies available to Brooklyn patients. Here is a straightforward guide to what it is and how it works. Why it remains underused is discussed in why EMTT therapy is underused for pain relief.
Breaking down the name
“Extracorporeal” means the treatment is applied from outside the body, without needles or incisions. “Magnetotransduction” refers to the way high-energy electromagnetic fields interact with tissue at the cellular level.
How EMTT differs from older magnetic therapies
EMTT uses significantly higher-intensity electromagnetic energy than older, lower-frequency magnetic devices, and is specifically designed to target inflammation and support tissue repair more directly. It should not be confused with PEMF, an older and generally lower-intensity technology.
What a treatment session looks like
Sessions are brief, typically ten to twenty minutes, and patients remain fully clothed throughout. No recovery time is needed afterward, and most patients return to normal activity immediately.
Conditions EMTT is commonly used for
EMTT is often used for chronic joint pain, tendon injuries, and soft tissue conditions that have not responded to rest or conservative treatment alone.
Why Brooklyn patients are asking about it
As a newer technology, EMTT is not yet available everywhere, and where it is available, it is often offered on a cash-pay basis. Coverage varies by clinic and by plan, so it is worth asking whether it can be billed through insurance, including Medicaid.
If conservative treatment has not resolved your pain, ask your provider whether EMTT could be part of your treatment plan.
Frequently asked questions
Is the magnetic field in EMTT like the one in an MRI scanner?
No. An MRI uses a continuous, very strong static field to produce images and is not intended to treat anything. EMTT applies pulsed, high-energy electromagnetic fields to one area for a short period, with the aim of influencing activity in the tissue. The field characteristics, the purpose and the safety considerations are different in each case.
How deep into the body does EMTT actually reach?
Magnetic fields pass through skin, fat and muscle without being absorbed the way light or sound is, so the field reaches deeper structures than most surface treatments. Field strength still falls with distance from the applicator, which is why positioning matters. Depth of reach is not the same as depth of effect, and that distinction is often blurred in marketing.
Why is EMTT not offered at every pain clinic?
Mostly cost and caseload. The equipment is a substantial capital purchase, it treats one patient at a time, and reimbursement for it is inconsistent, so clinics generally invest only where enough patients would use it. Newer technology also spreads slowly while clinicians wait for more published evidence. Limited availability reflects those economics rather than a verdict on the treatment.
Is EMTT the same as a TENS unit?
No. A TENS unit passes a small electrical current through electrodes stuck to the skin, mainly to change how pain signals are perceived while it is switched on. EMTT applies a magnetic field through the skin with no electrodes and no muscle contraction, aimed at deeper tissue and given as a course. The sensations and the intended effects are different.
Wondering whether EMTT applies to your condition?
A physician-led evaluation matches the technology to the diagnosis. More on EMTT therapy.
