The effectiveness of extracorporeal shockwave treatment in subacromial impingement syndrome and its relation with acromion morphology

摘要

Objective The aim of this study was to evaluate the effectiveness of the extracorporeal shock wave therapy in the subacromial impingement syndrome and its relationship with the acromion morphology. Methods Thirty patients (24 women, 6 men) with subacromial impingement were evaluated. The average age of patients was 53.6?±?9.8 years (range 39–80). Patients were divided into 3 groups according to the acromion morphology. ESWT 1500?at 0.12 am mL/mm2 violence was applied once a week for 3 weeks. Shoulder pain and disability index (SPADI) was used to assess function and pain scores of the patients. The evaluations were made prior to and 12 weeks after the ESWT. Results Thirteen shoulders had type 1 acromion, 11 shoulders type 2 acromion and 6 shoulders type 3 acromion. After ESWT, the SPADI pain score decreased from 16.1?±?5.1 (7–25) to 10.4?±?4.9 (1–20); SPADI functional score decreased from 37.3?±?19.8 (5–70) to 26.7?±?17.5 (1–60); SPADI total score decreased from 53.4?±?24.5 (14–95) to 37.1?±?21.6 (2–74) (p 0.05, one way ANOVA test). Conclusion ESWT was found to be effective in the treatment of impingement syndrome both for pain and functional outcome in the early period regardless of acromion morphology.
