Extracorporeal shock wave therapy, as a non-invasive treatment method, has been used in the treatment of various orthopedic diseases and chronic pain in recent years. The mechanisms of shock waves in the treatment of soft tissue pain may be: 1.Mechanical action, destruction of calcified and fibrotic tissue; 2.Analgesia, reverse stimulation of sensory nerves or axonal reflexes emanating from thin afferent fibers and dorsal root reflex impulses can release substance P at the peripheral end and stimulate pain receptors to block the increase in pain stimulation (gate control theory); 3.Tissue regeneration, improve blood perfusion and angiogenesis, increase mesenchymal stem cells, increase growth factors, Boost metabolism, etc.
