There is an educational offer that includes scientific societies, universities, industry, and even beginners, who simply by having access to social media become opinion makers.The level of risk associated with focused generators is different from that associated with radial sources [7]. For this reason and according to the consensus of most scientific societies [5,6,8], focused devices should be operated only by trained physicians.The aim of this review is to introduce the basic principles of quality and technical recommendations for each method.
Physical Principles and GeneratorsMost of the poor results of shock wave treatment are related to an improper diagnosis [10].RPW devices have two types of generators: electropneumatic and electromagnetic. These devices do not emit shockwaves because the rise times of the pressure pulses are too long and the pressure outputs are too low [2,3].
