In a multi-center, retrospective study, the effect of shockwave therapy was investigated in 119 patients with tendinosis calcarea of the shoulder treated in the period of 38 months from April 2001 to May 2004.
There were 64 women and 58 men with an average age of 56 (range, 37-79) years.

Each patient was treated with 1500 - 2000 impulses of shock wave, a 35 mm focus depth, and with an energy flux density of no more than 0.14 mJ/mm after local anaesthesia.
One treatment was performed on 111 patients and 8 patients underwent a second treatment. The subjects were evaluated by means of a clinical evaluation according to Roles and Maudsley scare, subjective outcome on Visual Analogue Scale QVAS) , X-rays and ultrasound analysis, 45, 90 and 180 days after the end of the therapy.
