PiezoWave 2t Therapy Mechanism of Action

Extracorporeal Shock Wave Therapy (ESWT) delivered via PiezoWave² / MyACT (Myofascial Acoustic Compression Therapy) works through a combination of physics and biological mechanisms: focused acoustic compression waves and mechanotransduction.   

Unlike radial pressure wave devices that strike the skin's surface, PiezoWave technology passes through superficial tissue without losing energy or causing surface discomfort, converging precise energy at a specific, adjustable depth within deep muscles, tendons, or fascia.   

1. Acoustic Wave Generation (Piezoelectric Effect)

• Piezo Ceramic Crystals: The treatment wand contains hundreds of piezo-ceramic crystals arranged in a mosaic array along a concave surface.   

  
  

• Electrical Stimulation: High-voltage electrical pulses excite these crystals simultaneously, causing them to rapidly expand along their axis.   

  
  

• Focused Convergence: This expansion generates an array of precise acoustic sound waves that move through tissue and converge at a single focal point deep below the skin. Interchangeable gel pad spacers allow the clinician to adjust the penetration depth.   

  
  

2. Physical & Mechanical Effects (Micro-Massage)

• Direct Deep Tissue Compression: At the focal point, the sound waves create an intense, extremely short burst of mechanical pressure. This acts like a targeted, microscopic deep-tissue massage.   

  
  

• Disruption of Adhesions and Calcifications: The mechanical force breaks down fibrotic scar tissue, fascial restrictions, and calcified deposits (such as those seen in calcific tendinopathy or chronic plantar fasciitis) without needing surgery or injections.   

  
  

• Trigger Point Deactivation: By mechanical compression, it deactivates hyper-irritable myofascial trigger points and relieves localized and referred pain.   

  
  

3. Biological & Cellular Response (Mechanotransduction)

The primary driver of long-term healing from MyACT is mechanotransduction—the process where cells convert physical mechanical stress into biological signaling:   

• Cellular Activation: Mechanosensitive cells (such as tenocytes in tendons, fibroblasts in fascia/ligaments, and endothelial cells in blood vessels) respond to the acoustic compression forces.   

  
  

• Boosted ATP Production: The mechanical stimulation promotes mitochondrial function, increasing cellular energy (ATP) production to accelerate repair processes.

• Improved Microcirculation & Neovascularization: Acoustic compression stimulates localized blood flow and triggers the release of growth factors that encourage new blood vessel formation (angiogenesis), delivering oxygen and nutrients to chronically ischemic tissue.   

  
  

• Controlled Regenerative Inflammation: The treatment induces a mild, localized biological response that restarts stalled healing in chronic injuries.   

  
  

4. Biofeedback & Precise Targeting

During treatment, healthy tissue typically feels minimal force or a light tapping sensation. However, when the acoustic focus passes over dysfunctional, inflamed, or scarred tissue, it triggers a distinct, dull "toothache-like" ache. This biofeedback allows the clinician to map out hidden pain generators and trigger points with extreme precision before delivering therapeutic pulses.
