Two clinics can own the same shockwave machine and get very different results, because the result depends on how the energy is delivered, not just the device. Four technique variables decide the outcome. Coupling: gel and air-free skin contact, so energy transmits into tissue instead of reflecting off the skin. Alignment: aiming a focused device’s focal point at the pathology, by exam, not imaging. Device type: true focused electromagnetic ESWT versus radial pressure wave. Dose: energy and protocol for your tissue. At Dynamic Athlete, focused shockwave is delivered by Aneesh Garg, DO, CAQ, who founded ASTI and researches how it should be done.
The device is the cabinet. The technique is what reaches your tissue. This page explains the four variables that change the result, so you can ask the right questions.
The Decision
When you compare clinics, the brochure leads with the machine. The machine matters, but it is only the cabinet. What reaches your tissue is decided by how the energy is coupled in, where it is aimed, which device type is used, and how it is dosed. Every one is a human call that varies between two clinics with identical equipment.
So judge the delivery, not the badge on the door: how the energy is coupled, how the target is located, whether the device is truly focused, and how the dose is set. The device is the same. The delivery is not.
Key Takeaways
- The result is about delivery, not just the device. Two clinics with the same machine can get very different outcomes, because technique decides what reaches the tissue.
- Coupling is the physics most clinics overlook. At an air gap nearly all of an acoustic wave reflects off the skin, so clean, air-free gel contact lets the energy in.
- Alignment and device type set the ceiling. The clinician aims a focused device’s focal point by exam and palpation, not imaging, and no technique turns radial pressure wave into focused ESWT (ISMST, ASMST, ASTI).
- Dose is chosen for your tissue. A 2012 randomized trial found the energy level alone changed outcomes on the same device, not a factory preset.
- Dynamic Shockwave+ delivers focused ESWT plus EMTT, performed by Dr. Aneesh Garg, DO, CAQ, who founded ASTI. Over 90% of our patients self-report a 75% or greater improvement, all without surgery. Self-reported, never guaranteed. HSA/FSA apply; Cherry financing spreads the cost.
The four things that decide your result
Coupling: get the energy into the tissue, or lose it at the skin
A shockwave is an acoustic wave, and it reflects almost completely at an air interface. Coupling crosses the wave from the device head into the body, through ample gel and air-free skin contact. At a water-to-air boundary, roughly 99.9% of the wave reflects rather than passing through, and coupling research (Pishchalnikov et al., Journal of Urology, 2006) shows even small trapped air pockets reduce delivered energy. Sloppy coupling means the same device underdelivers.
Alignment: the focal point only helps if it lands on the problem
Focused shockwave concentrates energy at a defined focal point the clinician aims at a chosen depth. That precision is wasted if the energy lands next to the problem instead of on it. Finding the diseased tissue is a clinical skill: the history, an exam that reproduces the pain, and the anatomy to place the focal point on the right tendon or deposit. Focused shockwave is not aimed by ultrasound or any imaging. The precision comes from the exam and palpation, not a screen.
Device type: true focused shockwave, not a radial substitute
The technique only goes as far as the device allows. True focused electromagnetic ESWT uses an electromagnetic generator to produce a real acoustic shockwave at a defined depth, up to about 6 cm. Radial pressure wave is pneumatic, disperses energy at the skin surface, and has no focal point. ISMST, ASMST, and ASTI classify them as distinct technologies, and no skill turns radial into focused shockwave. See the focused vs radial breakdown.
Dose: energy and protocol chosen for your tissue, not a preset
Dose means the energy flux density, the pulse count, and the interval between sessions, all set for your tissue. A 2012 randomized trial in Physical Therapy (Ioppolo et al.) treated the same shoulder condition at two energy levels on the same device and found the energy level alone changed the result. Reviews report outcomes vary with the protocol, not just whether shockwave was applied (Speed, 2014). A preset is a default, not a dose. See how a course is planned.
Why training sits underneath all four
Dr. Garg researches and teaches how shockwave should be delivered
Each of the four is a decision, and decisions track training. Most providers learn shockwave from a sales rep in a brief demo of which buttons to press. Dr. Aneesh Garg, DO, CAQ founded and directs the American Shockwave Training Institute (ASTI), where he trains the clinicians and physicians who deliver focused shockwave across the field, and is a CuraMedix Key Opinion Leader on focused shockwave and EMTT. At the 2026 ISMST Congress he presented “Same Device. Different Delivery.” on how training changes shockwave delivery. That work measured clinician implementation, not patient outcomes.
The bottom line
The device is the same. The delivery is not. Judge a provider on how they deliver it, not the brand on the cabinet. Written by Aneesh Garg, DO, CAQ, The Regen Doc, founder of ASTI.
