Table 2 Characteristics of the pressure waves generated with various ESWT/RSWT devices marketed in the United States

From: Treatment of chronic plantar fasciopathy with extracorporeal shock waves (review)

Wave characteristics Devices generating focused shock waves Devices generating radial shock waves
Pressure waves that fulfill the characteristics set out by the physical definition of shock waves belowa Ossatron (SONOCUR Basic)b and (Orbasone)b  
Pressure waves that do not fulfil the characteristics set out by the physical definition of shock waves belowa Orthospec and Epos Ultrac Swiss DolorClast
  1. The names of the corresponding manufacturers are provided in the main text. aPhysical definition of shock waves [15, 16]: (1) a high positive peak pressure (P+), sometimes more than 100 MPa but more often approximately 50 to 80 MPa, (2) a fast initial rise in pressure (Tr) during a period of less than 10 ns, (3) a low tensile amplitude (P, up to 10 MPa), (4) a short life cycle (I) of approximately 10 μs, and (5) a broad frequency spectrum, typically in the range of 16 Hz to 20 MHz; brise time not published; cwhen operated at levels 1 to 7 (i.e., as in clinical use for treatment of PF [26, 29]).
