Working principle: A physical therapy that uses high-energy sound waves to penetrate human tissue, stimulate damaged areas through mechanical stress and cavitation effects, and promote tissue repair and angiogenesis. The core principle is to induce local biological reactions through energy transfer, accelerating the healing process.
1、 The physical properties and mechanism of action of shock waves
High energy sound wave characteristics 1
Shock wave is a type of sound wave generated by equipment with high energy peaks and rapid pressure changes, typically in the frequency range of 0.1-0.3 MHz. It can penetrate the skin and soft tissues, accurately targeting deep lesions such as bones, tendons, or ligaments.
Mechanical stress effect 2
When sound waves reach damaged tissue, the mechanical stress generated directly stimulates the cell membrane and cytoplasm, activating cellular metabolism. For example:
Tendon/ligament injury: Stress promotes collagen synthesis and improves fiber arrangement;
Bone non union/delayed healing: Stress induces osteoblast activity and accelerates callus formation.
Cavitation effect 3
Sound waves in liquid environments (such as tissue fluids) can form tiny bubbles, which release energy when they rupture, clearing necrotic tissue, unclogging capillaries, and enhancing local blood circulation.
