In extracorporeal shock-wave therapy (ESWT), a wave is produced by a small explosion generated underwater inside an applicator. This wave is focused through a lens and transmitted into the tissue. This device electromagnetically generates an extracorporeal shock wave, producing a high-pressure peak in a very short amount of time (less than 2 seconds). This can penetrate deep into the tissue, up to approximately 4.7", with a precise focus on a small target, for treating heel pain due to chronic proximal plantar fasciitis.
