How does PiezoWave2t ESWT work?
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.  Â
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.  Â
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.  Â
Electrical Stimulation: High-voltage electrical pulses excite these crystals simultaneously, causing them to rapidly expand along their axis.  Â
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.  Â
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.  Â
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.  Â
Trigger Point Deactivation: By mechanical compression, it deactivates hyper-irritable myofascial trigger points and relieves localized and referred pain.  Â
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:  Â
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.  Â
Boosted ATP Production:Â 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.  Â
Controlled Regenerative Inflammation: The treatment induces a mild, localized biological response that restarts stalled healing in chronic injuries.  Â
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.  Â
