Focused Shockwave
This is generally used to treat targeted deep-rooted painful conditions and is particularly useful for joint related problems. The device uses piezoceramic crystals to generate a pressure wave through the tissue into the target area at a depth of 8cm. This creates cavitation bubbles which collapse, creating a secondary shockwave. This approach is less painful than the radial option. 

Radial Shockwave
This is ideal for 90% of the problems we see in clinic. For example, soft tissue/ tendons which are more superficial. In fact some studies have shown this treatment can help with osteoarthritis and bone healing such as delayed non-union fractures. This process works in the same way as the Focused approach except the Radial shockwave does not penetrate as deep and therefore its use is considered for more superficial conditions.
