The shock waves are believed to stimulate angiogenesis / neovascularization (new blood vessels) and neurogenesis (new nerve cells). The microtrauma increases local circulation and enhances breakdown of calcifications (calcium build-up).This non-invasive procedure typically lasts less than 20 minutes. Shockwave therapy works by emitting high energy pulses. These pulses of acoustic energy are focused on the target tissues by the handpiece / applicator of the shockwave therapy machine and are believed to cause localized microtrauma that stimulates the bodies natural healing processes.
