New to shockwave or in pain for more than 3 months? Book a Telehealth to see if we can help you!
You’ve done the exercises. You’ve tried the stretches, the ice, the heat, the anti-inflammatories. Maybe you’ve had a cortisone shot that worked for six weeks and then wore off. Your back, your shoulder, your knee—it still won’t settle. And now someone mentions EMTT therapy in Edmonton, and you’re thinking: is this real, or just another expensive gadget?
That’s a fair question. EMTT—Electromagnetic Transduction Therapy—is a non-invasive technology that delivers high-energy electromagnetic pulses into tissue from outside the body. It doesn’t replace your rehab plan. It amplifies it. At Unpain Clinic, we adopted the STORZ Magnetolith system in 2025 specifically because the published research supports what we see in practice: when you add EMTT to a structured treatment plan, pain and function outcomes can improve beyond what standard care achieves alone.
This post breaks down how EMTT works, what the research actually says, who it helps, and what to expect if you come in for a session. No hype. Just the evidence and the clinical reality.
Most people with persistent musculoskeletal pain aren’t doing nothing about it. They’re doing a lot. Physiotherapy, medication, rest, activity modification. The problem isn’t lack of effort. The problem is that the tissue environment—the cellular conditions where healing is supposed to happen—hasn’t shifted enough to break the cycle.
Here’s what that means. When tissue stays inflamed or irritated for weeks or months, the local biology gets stuck. Inflammatory signalling pathways like NF-κB and MAPK—which are part of your body’s damage response system—can remain active long after the initial injury. That sustained inflammation disrupts normal repair. Tendons don’t remodel the way they should. Pain signals keep firing. Function stays limited.
Standard conservative care (physiotherapy plus pain medication) addresses this from the movement and symptom side. It’s essential. But in many chronic cases, the tissue itself needs an additional biological stimulus to shift out of that stuck state. That’s where modalities like EMTT come in.
Think of it this way. Physiotherapy teaches your body how to move correctly and builds strength around a problem area. Medication manages the pain signal so you can participate in rehab. But neither one directly changes the electromagnetic or cellular signalling environment of the injured tissue. They work on the system around the problem. EMTT works on the tissue environment itself.
At Unpain Clinic, we see this pattern constantly: patients who have done months of good physiotherapy and still plateau. Their movement is better, their strength is improved, but their pain hasn’t dropped to where it should be. The missing piece is often biological—the tissue needs a stimulus that exercise and manual therapy alone don’t provide. That’s the gap EMTT is designed to address, and it’s why we use it as an adjunct—alongside modalities like shockwave therapy—never as a stand-alone fix.
EMTT is newer than modalities like shockwave or ultrasound, and the evidence base is still growing. That said, the published peer-reviewed research that does exist tells a consistent story: EMTT adds measurable value when combined with standard care.
The most detailed EMTT clinical trial is a prospective randomized controlled trial by Krath and colleagues, published in the Journal of Orthopaedics in 2017. This study looked at patients with non-specific low back pain. Both groups received the same standardized conservative program—physiotherapy plus analgesics. One group also received EMTT; the other received sham EMTT.
The results were clear. In the group that received real EMTT on top of standard care, average pain scores on the Visual Analogue Scale dropped from baseline to 2.64 at six weeks and 2.05 at twelve weeks. The study reports an overall 64.7% decrease in pain intensity. (Krath et al., 2017, Journal of Orthopaedics, RCT)
Disability scores told a similar story. The Oswestry Disability Score in the EMTT group decreased from 53.48 at baseline to 25.55 at six weeks and 20.82 at twelve weeks—a 61.07% total improvement. The control group improved too, but the EMTT group’s results were statistically superior at both measurement points. (Krath et al., 2017, Journal of Orthopaedics, RCT)
Importantly, these improvements held at the twelve-week follow-up after the last treatment session, suggesting the effects aren’t just temporary pain relief—they persist.
A second key study by Klüter and colleagues (2018, Electromagnetic Biology and Medicine, RCT) examined 86 patients with rotator cuff tendinopathy. This trial compared shockwave therapy (ESWT) combined with real EMTT against shockwave combined with sham EMTT.
The combination group—real EMTT plus real shockwave—achieved greater improvement in both pain and shoulder function scores than the shockwave-plus-sham group. This is significant because shockwave therapy on its own is already one of the better-supported modalities for tendinopathy. The fact that EMTT added measurable benefit on top of an already effective treatment suggests it’s contributing something biologically meaningful. (Klüter et al., 2018, Electromagnetic Biology and Medicine, RCT)
On the preclinical side, EMTT-specific research has demonstrated effects on human tenocytes (tendon cells) and on bone marrow mesenchymal stem cells in laboratory settings. One study showed gene upregulation and accelerated matrix mineralization in bone-healing cell models. Broader pulsed electromagnetic field (PEMF) research—the family of technology EMTT belongs to—has shown anti-inflammatory signalling effects through pathways including adenosine receptors and NF-κB, and support for tissue-repair biology including angiogenesis and osteogenesis. (Gerdesmeyer et al., 2024, Biomedicines; Schwabe et al., 2022, Electromagnetic Biology and Medicine; Vincenzi et al., 2013, PLOS ONE)
The takeaway: EMTT is not a miracle device. It’s a biologically plausible adjunct with early but consistent clinical evidence showing it can improve outcomes when added to a structured plan.
At Unpain Clinic, we never use EMTT as a stand-alone treatment. This isn’t a “lie down and get zapped” approach. EMTT is one component of a broader plan that may include shockwave therapy, manual therapy, neuromodulation, and targeted exercise—selected based on your specific assessment findings.
The way we think about EMTT is as a “fertilizer” for the tissue environment. Shockwave therapy creates a controlled mechanical stimulus that triggers a healing response. Exercise builds capacity and resilience. EMTT supports the cellular conditions that allow those interventions to work more effectively—by delivering patterned electromagnetic pulses that can influence inflammation-related signalling and nudge repair pathways into a more active state.
This combination approach is supported by the research. The Klüter et al. (2018) trial specifically showed that ESWT plus EMTT outperformed ESWT plus sham EMTT. The Krath et al. (2017) trial showed EMTT added to physiotherapy plus analgesics outperformed the same base care alone. The pattern is consistent: EMTT amplifies other treatments rather than replacing them..
In practice, a typical EMTT protocol involves sessions of approximately 20 minutes, delivered twice per week. Published research has used 8 sessions over a 6-week window at 80 mT and 3 Hz impulse frequency, delivered via the STORZ Cellactor MT1 device. Your specific protocol may differ based on your condition, severity, and what other modalities are included in your plan.

One thing patients consistently tell us: they don’t feel much during EMTT. Unlike shockwave, which delivers a noticeable mechanical pulse, EMTT is typically painless or produces only a mild sensation. Some patients with highly inflamed tissue may notice more, but most find it comfortable. That low-sensation profile is actually one of its clinical advantages—it means we can use it in acute and sensitized cases where other modalities might be too provocative.
Here’s a composite example based on common patterns we see at the clinic.
A 48-year-old office worker comes in with lower back pain that’s been present for five months. They’ve done eight weeks of physiotherapy. Range of motion is better. Core strength has improved. But pain is still at a 6 out of 10 most mornings, and sitting for more than 30 minutes is uncomfortable.
At their initial assessment, we identify that the tissue environment hasn’t responded fully to exercise alone. We build a plan that includes continued targeted exercise, shockwave to address specific tissue drivers, and EMTT to support the broader tissue biology.
Over the next six weeks, they complete their EMTT sessions alongside their other treatments. By week four, morning pain has dropped to a 3. By the twelve-week follow-up, they’re sitting through full workdays, exercising three times a week, and pain is a 1–2 on most days.
Not every case follows this timeline. Results may vary. But this pattern—where EMTT helps bridge the gap between “good rehab” and “full recovery”—is what we see most often.
EMTT supports your tissue biology. But what you do between sessions matters just as much as what happens during them. Here are three things that help your results build:
Pain-free movement keeps blood flowing to the treatment area and supports the repair processes EMTT is designed to stimulate. Walking 20–30 minutes daily is a good baseline. Avoid pushing into sharp pain, but don’t avoid all movement—gentle, consistent activity is your ally.
If you’re doing targeted exercises as part of your plan at Unpain Clinic, stay consistent with them. EMTT and exercise work together: the electromagnetic stimulus supports tissue-level repair, while exercise builds the strength and resilience that keeps pain from returning. Skipping your exercises undermines both.
Chronic stress and poor sleep both amplify inflammatory signalling in the body—the same pathways EMTT is working to modulate. You don’t need a perfect sleep routine, but aim for 7–8 hours and reduce late-night screen exposure when you can. Even small improvements in sleep quality can support your treatment outcomes.
These aren’t complicated steps. But they compound. Patients who stay active, do their exercises, and manage their recovery between visits tend to respond faster and maintain their results longer.
EMTT stands for Electromagnetic Transduction Therapy. It delivers brief, high-energy electromagnetic pulses from outside the body into a target tissue area. These pulses can influence cell-membrane signalling pathways linked to inflammation regulation and repair processes. It is non-invasive and does not involve needles, surgery, or medication.
Most patients feel little to nothing during treatment. Unlike shockwave therapy, which produces a noticeable pulse, EMTT is typically painless. Some patients with highly inflamed tissue may notice a mild sensation, but treatment is generally well tolerated. If you have concerns, your clinician can adjust parameters during the session.
Published research has studied protocols of 8 sessions delivered twice per week over 6 weeks. Your specific plan may vary depending on your condition and what other modalities are included. Your clinician will outline the recommended number of sessions during your initial assessment.
In the published randomized controlled trial on EMTT for low back pain, investigators reported no clinically relevant adverse events. Some temporary skin redness immediately after treatment has been noted. EMTT is contraindicated for people with active implanted electronic devices (pacemakers, cochlear implants, neurostimulators), during pregnancy, and for direct treatment on the brain. If you have passive metal implants, your clinician will assess your suitability with appropriate precautions.
EMTT belongs to the broader family of pulsed electromagnetic field therapies, but it operates at higher energy levels than most consumer PEMF mats or home devices. The clinical research on EMTT uses specific device parameters (80 mT, 3 Hz) delivered via a medical-grade STORZ applicator. Results from consumer PEMF products cannot be directly compared to EMTT clinical trial outcomes.
There are no published head-to-head trials comparing EMTT directly to surgical interventions. EMTT is best understood as a non-invasive adjunct within conservative care—not as a proven surgery replacement. That said, if conservative treatment including EMTT resolves your pain and restores your function, surgical intervention may become unnecessary. Your clinician will help you understand where you stand.
EMTT pricing varies depending on the number of sessions and what other modalities are included in your treatment plan. At Unpain Clinic, we provide transparent pricing at your initial assessment before you commit to anything. Contact the clinic directly for current rates and package options.
EMTT is not a miracle fix. It’s not a replacement for physiotherapy, exercise, or a proper clinical assessment. But for patients with chronic musculoskeletal pain who have plateaued on standard care, the published evidence supports what we see at Unpain Clinic: adding EMTT to a structured treatment plan can meaningfully improve pain and function outcomes.
The technology is non-invasive, well-tolerated, and studied in peer-reviewed randomized controlled trials. It works best as part of a combination approach—alongside shockwave, targeted exercise, and hands-on treatment. If you’ve been stuck in a cycle of partial improvement and recurring pain, EMTT therapy in Edmonton may be the adjunct that helps your body finally complete the healing process.
