Focused, radial and combined shock wave therapy in treatment of calcific shoulder tendinopathy

ABSTRACT

Objective: The aim of this work is to compare the clinical, functional, and ultrasonographic outcomes of focused, radial, and combined extracorporeal shock-wave therapy (ESWT) in the treatment of calcific shoulder tendinopathy.

Methods: we enrolled 45 patients with calcific shoulder tendinopathy, their ages ranged from 30 to 68 (50.93 ± 9.44) years, classified according to the line of treatment into three groups, all received four sessions of ESWT 1 week apart.

Group I: 15 patients received focused shock waves (F-SW) 1500 shocks.

Group II: 15 patients received radial shock waves (R-SW) 2000 shocks.

Group III: 15 patients received combined focused and radial shock waves (C-SW). All patients were evaluated by musculoskeletal ultrasound (MSK US) before treatment, at 1 week and at 3 months after the last session.

Results: In the three studied groups, there was a significant improvement in shoulder pain, active range of motion (ROM), and shoulder function by shoulder disability questionnaire (SDQ) at 1 week after the end of treatment and after 3 months follow up. Moreover, there was a significant sonographic reduction in calcification size in the three groups. At the end of the study, the best improvement as regards a decrease of calcification size was obtained in group III when compared with group I and group II.

Conclusion: These results demonstrated clinical, functional, and sonographic improvement in all groups. The best therapy in calcific shoulder tendinopathy appears to be combined focused and radial ESWT compared to interventions alone. Level 1 Evidence Randomized control study.
