Shock wave therapy was first used in the 1980s for
contactless fragmentation of kidney stones. In the
1990s, orthopaedists started to incorporate this
therapy modality into their practice, initially for the
treatment of bone non-union or delayed union and
tendon problems.
Radial and focused shock wave therapy
Shock waves are high-energy sound waves created
when jet fighters break the sound barrier, for
instance. In physical terms, one speaks of a shock
wave when the pressure changes abruptly within an
extremely short distance (less than one forth of the
pulse length). Typical features of shock waves are:
//
steep pressure rise within 10 ns and at ambient pressure up to 100 MPa; followed by a negative pressure tensile wave component up to 10 MPa.
The following shock wave therapy modalities
should be distinguished because they differ in their
effectiveness, in the equipment costs and with
respect to their classification in the medical fee
schedule:

Radial shock wave therapy – pressure waves
Radial shock waves are produced mechanically by
means of compressed air. Using a pistol-shaped
handpiece, a projectile is accelerated to a speed of
several metres per second until it strikes an impact
body. The projectile transmits its kinetic energy to
the impact body which then passes it on to the
coupled tissue. The energy produced with this
ballistic method of pressure wave generation is not
equivalent to the energy level and physical
characteristics of focused shock waves.

Focused shock wave therapy
Contrary to radial pressure wave generation,
focused shock wave systems use electrohydraulic, piezoelectric or electromagnetic generators to Professor Karsten Knobloch, M.D.

of focused shock waves is ten times higher than that of radial shock waves, which means that a significantly higher amount of energy can be Technological progress in extracorporeal shock wave therapy during the last few years has significantly enhanced treatment options for top-class athletes. As early as in 2008, a field report by Professor Lohrer on the use of shock wave therapy at the Frankfurt Olympic Training Centre was published in this journal (medicalsports network 03.08). The report also covered the use of shock waves in the treatment of athletes during Olympic Shock wave therapy of tendon injuries
