There are no electric shocks involved.
An air compressor accelerates a metal projectile inside the applicator head at a rate of 1-20 times per second. The kinetic energy of the projectile is converted into a high-pressure acoustic wave when it comes into contact with the applicator head.
The shockwave/pressure wave exerts a mechanical stimulus on the tissue being treated resulting in chemical changes taking place within the cell. The most important effects as a result of the chemicals released are pain relief and increased repair of the injured tendon or tissue.
