How does shockwave technology work? Physics made simple
The essentials in brief
- Shock wave technology works with mechanical, acoustic pressure waves. It is not an electric current, not a laser, and not a vibrating massage: the wave is generated by a physical collision.
- In pneumatic devices, the process is: compressed air, accelerating projectile, collision with the head, pressure wave, which travels through the head into the tissue.
- The radial shock wave spreads out from the surface to a depth of approximately 3.5 cm. The focused version concentrates energy on a single point; this is a medical specialist area.
- Three parameters describe the device: pressure (bar), frequency (Hz), and the size and shape of the heads.
- The compressor and the projectile are wearing parts. When choosing a device, guaranteed shot count and serviceability are more important than the number of programs.
- The MovTech Shock Wave is a regeneration tool, not a medical device. It must not be used without medical consultation in case of pregnancy, taking anticoagulants, implanted devices, tumors, or any existing health condition.

Shock wave is one of the most misunderstood tools on the regeneration market. Based on the name, many people think of some kind of electrical or light-based device, even though the operation is purely mechanical and its physics can be explained simply.
In this article, we will go through what happens inside the device, what the technical data means, and what you should know about the technology before choosing anything. The focus is on the technology, not on promises.
What is shock wave technology?
In shock wave technology, a device delivers short, high-energy acoustic pressure waves into soft tissues through a handpiece. The wave is generated by a mechanical impact, so it is not electrical stimulation or light. The method belongs to the category of regeneration tools; MovTech Shock Wave devices are not medical devices.
In search queries, people typically look for it as a shock wave machine, shock wave device, or home shock wave tool. We consistently call it technology because the device itself utilizes a technology and does not perform a medical procedure.
The physics step-by-step
There are four steps in a pneumatic shock wave device: the compressor produces compressed air, the air accelerates a metal projectile in a tube, the projectile hits the head fixed in the handpiece, and the energy of the collision is transferred through the head into the tissue in the form of a pressure wave. The entire process takes place in milliseconds and is repeated multiple times per second.
| Step | What happens |
|---|---|
| 1. Compressed air | The compressor pressurizes the air, this is the set bar value |
| 2. Acceleration | The air accelerates the metal projectile in a tube |
| 3. Collision | The projectile hits the head of the handpiece, the energy is transferred |
| 4. Pressure wave | An acoustic pressure wave starts from the head into the tissue, spreading out |
This is why a characteristic knocking sound is heard while the device is operating: the sound is the impact of the projectile. And this is why the projectile and the tube are wearing parts, as tens of thousands of physical collisions take place in them.
Radial and focused: what is the difference?
Radial shock waves spread out from the surface of the head in a cone shape and exert their effect in the layers close to the surface, typically up to a depth of about 3.5 cm. Focused shock waves, by contrast, concentrate energy at a specific depth. The two technologies require different equipment, different training, and represent a different scope of use: focused devices belong to medical and clinical fields.
In the home and professional regeneration market, you will almost exclusively encounter radial devices. MovTech's Shock Wave devices also operate with radial technology.
Pressure, frequency, heads: the parameters
Pressure (bar) indicates the energy with which the wave starts. Frequency (Hz) is how many impacts occur per second. The size and shape of the head determine how large an area the energy is distributed over. The three together create what the user perceives as intensity.
- Pressure (bar): lower values are gentler, higher values are more assertive. Always start lower and increase based on feedback.
- Frequency (Hz): lower frequency gives individually perceptible impacts, higher frequency is more like a continuous, dense knocking. Higher is usually suitable for working on larger areas, lower for targeted work.
- Heads: a larger diameter head distributes energy more gently over a larger area, a smaller one more concentratedly. Choosing the head is just as important as setting the pressure.
- Shot count: the unit of work. In professional practice, a body area typically gets a few thousand shots, not a set number of minutes.
What to look for when choosing a device?
Mechanics are much more important than the number of programs: what kind of compressor drives it, how many shots it is rated for, whether the wearing parts are replaceable, and whether there is service available for it. A shock wave device is a mechanical machine, so its long-term usability is determined by the supply of parts.
- Guaranteed shot count. This is the unit of measure for the expected lifespan of the device. It is worth asking about.
- Replaceability of wearing parts. The projectile, tube, and seals wear out. If they cannot be replaced, the device is disposable.
- Head set. There should be at least one larger and one smaller diameter head, because without this, you cannot adjust the work to the body area.
- Noise level and cooling. Compressor devices are noisy. If you use it regularly for long periods, this matters.
- Service and training. The use of the technology must be learned. It is worth choosing training along with the device.
If you would like to try it first: the Shock Wave is also available for rent. During a rental period, you will find out if it fits into your own practice or routine before you buy it. The full range is in the shock wave machines and training collection.
At home or with a professional?
To use radial shock wave devices, you must know the body areas, the settings, and the contraindications. Therefore, the technology is primarily a tool for massage therapists, physiotherapists, and coaches, and is recommended for home users only after training. The device is not a medical device and is not suitable for treating medical conditions.
If you have a complaint, it is best to turn to a professional first. The device does not diagnose and does not replace a medical examination: a professional will decide whether this technology is even an option for you.
When should it not be used?
Shock wave technology cannot be used:
- during pregnancy;
- in case of taking anticoagulants or blood clotting disorders;
- in case of tumors;
- in the area of implanted devices (pacemaker, prosthesis, metal implant);
- on open wounds, inflamed, infected, or damaged skin surfaces;
- directly on the head, spine, large blood vessels and nerve trunks, chest, and abdominal area;
- in children and on growing bone surfaces;
- in case of fever or infection.
In case of any existing health condition, regular medication, or recent surgery, ask your doctor first. This list is informative, not exhaustive: the device's user manual is authoritative.
Where can you learn how to use it?
With shock wave, knowing the settings and body areas is the most important thing, and this cannot be learned from reading. The shock wave technology device course presents the settings, head selection, and safety rules. For professionals, the full training offer is also available.
In summary
Shock wave technology works on a mechanical principle: compressed air accelerates a projectile, and the collision creates an acoustic pressure wave that spreads radially into the tissue to a depth of approx. 3.5 cm. The device is described by pressure, frequency, and heads, and its long-term usability is determined by the mechanics and part supply.

MovTech Shock Wave devices are regeneration tools, not medical devices. Before use, study the user manual, and if in doubt, ask your doctor.
