Überlegene Leistung des EMS DolorClast Radial Shock Waves

Eine neue Vergleichsstudie zwischen dem EMS DolorClast®️ Radial Shock Waves und dem Storz MASTERPULS®️ 200 ultra zeigt deutliche Unterschiede in der Energieabgabe bei höheren Frequenzeinstellungen.

Die radiale extrakorporale Stoßwellentherapie (rESWT) ist eine sichere und wirksame Behandlungsmethode für eine Vielzahl von Erkrankungen des Bewegungsapparats. Ihre Wirksamkeit hängt von der Energieabgabe bei evidenzbasierten, klinisch relevanten Geräteeinstellungen ab.1 Daher begannen Forscher im Jahr 2015 zu untersuchen, wie sich verschiedene rESWT-Geräte hinsichtlich ihrer Energieabgabe unterscheiden.2 

Diese Unterschiede wurden in einer aktuellen Vergleichsstudie von Nina Reinhardt und Kollegen am Helmholtz-Institut für Biomedizinische Technik der RWTH Aachen (Aachen, Deutschland) weiter untersucht.3 Die Autoren dieser Studie verglichen das neueste EMS DolorClast® Radial Shock Waves Gerät und das Storz MASTERPULS® 200 ultra Gerät. Sie fanden erhebliche Unterschiede bei der Gesamtenergie, die an einen Patienten abgegeben werden kann.3

Radiale Stoßwellengeräte unterscheiden sich erheblich in ihrer Energieabgabe.

Warum ist das für praktizierende Therapeuten wichtig? Weil die neueste wissenschaftliche und klinische Forschung bestätigt hat, wie wichtig eine höhere Energieabgabe für bessere Behandlungsergebnisse ist. Doch nicht alle Geräte sind in der Lage, eine hohe Energie zu liefern. Lesen Sie mehr über die erstaunlichen Erkenntnisse dieser neusten Studie.  

 

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:

  1. Unique 2-compressor technology delivers constant air pressure to the DolorClast® BLUE handpiece
  2. 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.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.

Therefore, practitioners should choose a rESWT device that provides high energy output.

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.

These study results may not apply to other radial shock wave devices, which do not deliver the same energy output.
