EMTT therapy: what the Storz Magnetolith does differently from shockwave

The decision is whether a contact-free magnetic pulse is a different tool from an acoustic shockwave, or whether the two names are advertising for one console. They are not one console. Extracorporeal magnetotransduction therapy, EMTT, is a high-energy pulsed electromagnetic field. In this office it comes from a Storz Magnetolith. Shockwave is a pressure wave that has to be coupled into the skin. If you came here to find out whether the Magnetolith is "shockwave without the tapping," the physics answer is no. The evidence answer is narrower still, and it is mostly a low-back answer.

A field, not a hammer

Shockwave launches a mechanical wave. Radial units do it from a striking transmitter. Focused units shape the wave so a peak lands at a depth. Either way, gel and contact are part of getting sound-level pressure into tissue. EMTT does not rely on that acoustic couple. The Magnetolith generates a pulsed electromagnetic field outside the body. The therapeutic idea, stripped of slogans, is that a strong, rapidly changing magnetic field can influence cellular behavior in the tissue under the applicator without a projectile hitting a cap. This page will not invent tesla values, pulse frequencies, or penetration depths in centimeters. The practice has not published those settings, and a copied spec sheet from a sales deck is not a clinical protocol.

What a patient can verify without a physics degree is the setup. There is no gel ribbon required in the way a shockwave session requires one. The applicator is positioned over a region rather than tapped along a tendon. You are not being struck. Whether you feel warmth, a twitch, or very little is something the open doctor interview still needs to describe in this clinic's words. Until that description exists, this guide will not script a sensation and then pretend you were promised it.

The shockwave side of that table is explained on /radial-vs-focused-shockwave and scored on /does-shockwave-therapy-work. The practice's own EMTT wording is on the EMTT page. The hardware list that places the Magnetolith next to the shockwave carts and the lasers is the technology inventory. Shockwave therapy remains a different service even when it is discussed on the same afternoon.

The trial is a back trial

Krath and colleagues, Journal of Orthopaedics, 2017 (opens in a new tab), also available in full text through PubMed Central (opens in a new tab), studied electromagnetic transduction therapy for non-specific low back pain. The design that matters for a patient is simple. One group received EMTT plus usual care. The other received usual care. EMTT was given as eight sessions over six weeks. The combination came out ahead of usual care alone. The authors described the result as promising. This page stops at those facts. It does not add a percentage the paper is not being quoted for, and it does not upgrade "promising" into "established" or "curative."

Non-specific low back pain is a large, mixed bucket. MedlinePlus on back pain (opens in a new tab) is clear that the symptom has many sources, from muscle and joint strain to problems that are not musculoskeletal at all. A trial in that bucket can support a careful trial of EMTT inside a broader plan for a similar back problem. It cannot be dragged across the body and relabeled as heel evidence. Plantar fasciitis has its own shockwave literature. That literature is acoustic, and the focused plantar trial (opens in a new tab) is not an EMTT paper. If a page, an ad, or a conversation treats the Krath result as proof that EMTT fixes plantar fasciitis, Achilles pain, or a knee tendon, the conversation has changed the study's question.

Usual care in that trial is doing real work in the comparison. EMTT was added to it, not crowned as a replacement for it. Exercise, activity changes, and the ordinary handling of a back complaint were the baseline. A Magnetolith session that is sold as the whole plan, with usual care deleted, is not the intervention the paper tested. Knee pain that is really a joint or tendon problem has its own guide, /knee-pain-without-surgery, and should not be quietly annexed by a low-back abstract.

Uncommon hardware is a reason people travel, not a census

A Storz Magnetolith is not a device every chiropractic office has plugged in. Patients drive to a building that owns one because the alternative is a clinic that can only talk about the category. This office is one of the places that owns the unit. That sentence is as far as the census goes. This guide will not estimate how many Magnetolith systems are in California or the United States, will not claim a first, and will not imply that distance traveled improves the odds. Uncommon equipment can still be the wrong equipment for a given person. The exam is the filter. The drive is just a drive.

There is also no posted session rate for EMTT. A range would be a fiction until the practice approves one, which is why price sits in the open items. Payment methods the office already lists, such as card, HSA or FSA, CareCredit, Cherry, and plan benefits that vary, are not a fee. Most PPO and HMO plans and Medicare are named as accepted categories, with coverage that still depends on the specific benefit. EMTT is not manual spinal manipulation, and Medicare's published chiropractic benefit is about that manipulation. Do not assume the benefit pays for a magnetic-field series.

The screen is longer than the shockwave screen, and it should be read against the manual

The clinic has published an EMTT screening list. It includes a pacemaker or defibrillator, pregnancy, active cancer in the treatment area, a seizure disorder, and deep-vein thrombosis or another clot. The field is not applied over the head or the face. It is not applied over infection, an open wound, or acute inflammation. That is the public list. The instructions for use that shipped with the device are the list that actually governs the button, and confirming the two lists against each other is still an open task. If the manual is stricter, the manual wins. If a future signed protocol adds a limit, the page should gain that limit rather than argue with it.

Two mix-ups cause real harm. The first is assuming a person cleared for shockwave is cleared for EMTT. A pacemaker is the example the practice itself separates: pacemaker screening is an EMTT issue in the published materials, not a shockwave footnote. The second is treating "no implant" as the whole screen. Pregnancy, seizures, clot history, and active cancer in the area are not implant questions, and they are not optional small print. Acute inflammation and an open wound are local reasons to wait or to choose a different room. None of this is a claim that EMTT is dangerous for everyone else. It is a claim that the screen is part of the therapy, not paperwork after the fact.

Class IV laser, a third energy in the same building, has its own hazard class and its own non-transferable evidence. It is compared on /class-iv-laser-therapy. Laser, shockwave, and EMTT can appear in one treatment plan only when each has a reason. Stacking them because all three are on the inventory is how a building tour impersonates a diagnosis.

What to ask before you book around the device

Ask what condition the exam thinks you have, and whether that condition resembles non-specific low back pain or something the Krath paper never enrolled. Ask what usual care would be even if the Magnetolith stayed off. Ask which line of the screening list applies to your implants, your pregnancy status, your cancer history, your seizures, your clots, and the skin over the area. Ask what the session will cost after the plan exists, and ask it before you start. The main-site EMTT page is the practice speaking in its own voice. This guide is the fence around the evidence: a contact-free magnetic field, a promising add-on to usual care in one low-back trial of eight sessions over six weeks, and a refusal to pretend that trial was about a heel.
