Radial Shockwave is the application of a high-energy acoustic pulse transmitted into the tissue of the affected area. It has been scientifically proven to relieve chronic pain associated with heel spurs, Achilles tendonitis, calcific shoulder tendonitis, and many other chronic conditions. Only 3 treatments are required, approximately one week apart. There may be some discomfort associated with the treatment but not intolerable. Most clients feel significant improvement after just the first treatment. If you are suffering from a chronic condition that has not responded to other forms of treatment, we would encourage you to consider shockwave. Not all shockwave units are created equal. Swiss DolorClast® has been scientifically proven to be effective with 3 treatments only. Other less expensive brands require more sessions to obtain results. If you are considering shockwave, make sure it is Swiss DolorClast®.
