1Shock wave pain therapeutic apparatus is a physics mechanism through the medium (air or gas) conduction of mechanical wave pulse pressure, produced by pneumatic pulse sound waves into precise ballistic shock wave, movement and positioning of probe throug 2Shock wave can change the chemical environment of the injury site, making the tissues produce and release pain-inhibiting chemicals. Meanwhile, shock wave can destroy the membrane of pain receptor, inhibit the production and propagation of pain signals. 3Increase of cell wall permeability, stimulation of microcirculation (Blood, Lymph), release of substance P, reduction of unmyelinated nerves, release of Nitric oxide (vasodilation, increased cell metabolism, neoangogenesis, anti-inflammatory effect), sti 4Pain relieve and treatment for plantar fasciitis, Achilles tendinitis, shoulder joint tendon inflammation and calcification, groin pain, epicondylitis. 5The patients can feel first effects directly after treatment, pain relief/ reduction after a few treating sessions, good treatment compliance.
