PERFORMANCE EXCEPTIONNELLE du DolorClast® D'EMS
La thérapie par ondes de choc extracorporelles radiales (rESWT) est une méthode de traitement sûre et efficace pour une variété de troubles musculo-squelettiques. Son efficacité dépend de l'énergie délivrée par les appareils selon des paramètres cliniquement pertinents et fondés sur des données probantes.1 C'est pourquoi les chercheurs ont commencé en 2015 à étudier les différences entre les différents appareils de thérapie par ondes de choc extracorporelles radiales en termes d'énergie délivrée.2
Ces différences ont été approfondies dans une récente étude comparative menée par Nina Reinhardt et ses collègues de l'Institut Helmholtz d'ingénierie biomédicale, RWTH Aachen (Aix-la-Chapelle, Allemagne).3 Les auteurs de cette étude ont comparé les dernières ondes de choc radiales - EMS DolorClast® Radial Shock Waves - et le Storz MASTERPULS® 200 ultra. Ils ont constaté des différences substantielles concernant l'énergie totale pouvant être délivrée à un patient.3
Les dispositifs d'ondes de choc radiales varient considérablement dans leur capacité à délivrer de l'énergie.
Pourquoi est-ce important pour les praticiens ? Parce que les dernières recherches scientifiques fondamentales et cliniques ont confirmé l'importance de délivrer des énergies plus élevées pour obtenir de meilleurs résultats de traitement. Pourtant, tous les appareils ne sont pas capables de délivrer des énergies élevées. Vous trouverez ci-dessous de plus amples informations à ce sujet.
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 thérapie par ondes de choc radiales permet de réduire les temps d'arrêt chez les sportifs de haut niveau et de diminuer le taux de rechute.
Une collaboration entre différents chercheurs l'université Ludwig-Maximilians de Munich (/Munich, Allemagne) et le personnel médical d'une équipe de football d'élite concourant dans la première/seconde Bundesliga a évalué rétrospectivement le traitement et les temps de récupération de 31 joueurs de football professionnels, qui avaient tous des blessures musculaires.7
Les principales conclusions de cette étude sont les suivantes:
- Incorporer les rESWT/fESWT dans une approche thérapeutique multimodale est sûr, efficace et bénéfique pour les athlètes souffrant de diverses blessures musculaires.
- Les durées moyennes d'arrêt de travail après des blessures musculaires de type 1a (tension musculaire/hypertonie) et 2b (claquage musculaire) étaient 50% plus courtes que les cas comparables rapportés dans la littérature.
Au cours de cette étude, les traitements ont été effectués dans la majorité des cas à 20Hz. Les résultats positifs ont été liés à la haute énergie délivrée par les appareils EMS DolorClast®️ utilisés à haute fréquence.
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.

6) 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.
