RENDIMIENTO SUPERIOR DE LAS ONDAS DE CHOQUE RADIALES EMS DOLORCLAST
El tratamiento con ondas de choque extracorpóreas radiales (rESWT) es una modalidad de tratamiento segura y eficaz para diversas afecciones musculoesqueléticas. Su eficacia depende de la salida de energía en los ajustes del dispositivo basados en la evidencia y clínicamente relevantes.1 Por lo tanto, los investigadores empezaron a investigar en 2015 cómo difieren los diferentes dispositivos de rESWT en cuanto a su salida de energía.2
Estas diferencias se investigaron más a fondo en un reciente estudio comparativo realizado por Nina Reinhardt y sus colegas del Instituto Helmholtz de Ingeniería Biomédica, RWTH Aachen (Aquisgrán, Alemania).3 Los autores de este estudio compararon el último dispositivo de EMS, DolorClast® Radial Shock Waves y el Storz MASTERPULS® 200 ultra. Encontraron diferencias sustanciales en cuanto a la energía total que puede suministrarse a un paciente.3
Los dispositivos de ondas de choque radiales varían significativamente en su producción de energía.
¿Por qué es importante para los profesionales? Porque las últimas investigaciones científicas y clínicas han confirmado la importancia de una mayor entrega de energía para obtener mejores resultados en el tratamiento. Sin embargo, no todos los dispositivos son capaces de suministrar una energía elevada. Lee más sobre estas reflexiones a continuación.
New study comparing the EMS DolorClast® Radial Shock Waves and the Storz MASTERPULS® 200 ultra devices
Influence of the pulse repetition rate on the acoustic output of ballistic pressure wave devices
Nina Reinhardt*, Jens Wegenaer & Matías de la Fuente Link to full study
In this bench test study, two rESWT devices and their energy output at different settings were investigated in a high-precision, experimental test setup:
- EMS DolorClast® Radial Shock Waves with BLUE handpiece and 15-mm applicator
- Storz MASTERPULS® 200 ultra with FALCON handpiece and 15mm applicator
Both devices were used up to their highest possible energy output settings.
The results of this study showed that by increasing the frequency setting (pulse repetition rate, PRR) the energy delivery varied between the two devices:
- The maximum energy delivery4 dropped sharply, up to 90.9%, for the Storz Medical MASTERPULS® 200 ultra.
- However, it only decreased slighly, 18.8%, for the EMS DolorClast® Radial Shock Waves device.
DolorClast® Radial Shock Waves delivers high energy at all frequencies
The EMS DolorClast®️ Radial Shock Waves device succeeded in delivering clinically relevant energy outputs at all frequency levels. This is important for clinical practice, because clinical outcomes require sufficient energy delivered to the tissue.
Reinhardt et al. (2022) concluded that manufacturer-reported energy levels at 1 Hz cannot guarantee outcomes at higher frequencies.3 The study demonstrated that the EMS DolorClast®️ Radial Shock Waves device guarantees a high energy output at all frequency settings.
Where do the differences in energy delivery come from?
For more than 20 years, EMS DolorClast® Radial Shock Wave has followed clinical evidence: To achieve the best therapy results, high-energy shock wave therapy has proven the most efficient. The high energy delivery of the EMS DolorClast® Radial Shock Waves device is enabled by the combination of highly effective air management of the compressors and the unique design of the EVO BLUE and BLUE handpieces.6
EMS pushed physics to the limit to achieve maximum energy output at all frequencies to successfully treat indications for orthopedics and sports medicine:
- Unique 2-compressor technology delivers constant air pressure to the DolorClast® BLUE handpiece
- Optimized air management in the hand piece for maximum projectile speed
The results are optimized radial extracorporeal shock waves to deliver stable, reproducible high energy to the treatment area. DolorClast® Radial Shock Waves delivers up to ten times more energy than the Storz MASTERPULS® 200 ultra.3
How relevant are high energy output and frequency for clinical practice?
High-energy radial shock wave therapy delivers superior therapy outcomes compared to low-energy radial shock wave therapy.
This has been confirmed again by a recent study from 2021, in which high and low energy radial shock wave therapy and their effect on pain relief (VAS) for patients with knee osteoarthritis were investigated.6 In this study, the DolorClast® EVO Blue handpiece was used with a 10mm applicator at a shock frequency of 8Hz.
This study demonstrated that high-energy therapy (0.24 mJ/mm2) resulted in better therapy outcome than low-energy therapy (0.12 mJ/mm2).
In addition, low-energy could not be compensated by increasing the number of shocks, as the latter did not result in better treatment outcome.6
Therefore, practitioners should choose a rESWT device that provides high energy output.
La terapia de ondas de choque radiales puede reducir los tiempos de inactividad en los deportes de élite y disminuir las tasas de reincidencia.
Una colaboración entre investigadores de la Universidad Ludwig-Maximilians de Múnich (Múnich, Alemania) y el personal médico de un equipo de fútbol de élite que compite en la primera/segunda Bundesliga alemana evaluó retrospectivamente el tratamiento y los tiempos de recuperación de 31 futbolistas profesionales, todos ellos con lesiones musculares agudas.7
Las principales conclusiones de este estudio fueron las siguientes:
- La incorporación de la rESWT/fESWT a un enfoque terapéutico multimodal es segura, eficaz y beneficiosa para los deportistas que sufren diversas lesiones musculares.
- Los tiempos medios de reposo tras las lesiones musculares de tipo 1a (tirantez/hipertonía muscular) y 2b (lesión por distensión muscular) fueron un 50% más cortos que los casos comparables recogidos en la literatura.
Los tratamientos durante este estudio se realizaron en la mayoría de los casos a 20 Hz. Los resultados positivos se relacionaron con la alta entrega de energía proporcionada por los dispositivos EMS DolorClast®️ utilizados a altas frecuencias.
Summary
In short, by using an EMS DolorClast®️ radial shock wave device, you will benefit from:
- High energy at all treatment frequencies
- Clinically-proven treatment outcomes
- Shorter treatments for improved patient experiences
- Greater success in your practice
This is the aim of Guided DolorClast® Therapy.
The bench test comparative study conducted by Reinhardt et al. (2022)3 demonstrated that the DolorClast® Radial Shock Waves device delivered higher energy than the Storz MASTERPULS® 200 ultra - especially at the high-frequency settings applied in practice.3
The effects achieved by the EMS DolorClast® Radial Shock Waves device may not be achieved with devices with significantly lower energy output.
We prove: EMS DolorClast® devices lead in the field of clinical evidence and therapy results
More than 50% of all published level 1 clinical trials with a radial shock wave device are done with an EMS Dolorclast® device.1,8
In 80% of these studies, treatments with EMS DolorClast® radial shock wave devices demonstrated better clinical outcomes than control groups.1
More than 60% of all studies that proved the cellular and biological effects of radial shock waves are done with EMS DolorClast® devices.9
These study results may not apply to other radial shock wave devices, which do not deliver the same energy output.

5) The EVO Blue and the latest generation BLUE handpiece both use the same technology and therefore deliver almost identical energy outputs. On the other hand, the compressor technology and the power input measured in bar is of minor importance, as the energy management and transformation in the handpiece is the decisive criteria for energy output.
