Besides the Chatanooga ultrasound and Interferential machine, we now have the top global Shockwave machine, the Swiss Dolorclast.

Shock wave therapy is a mechanical stimulus applied to tendon, bone or muscle.

It is particularly effective in chronic tendon injuries such as Plantar Fasciitis, Achilles Tendonosis (insertional and mid section), golfers and tennis elbow, lower back pain, subacromial pain syndrome, patellar tendinosis, greater trochanteric pain syndrome, shoulder calcification and even the break down of cellulitus.
