Abstract

[Purpose] The purpose of this study is to compare effectiveness of extracorporeal shock wave therapy (ESWT), ultrasound (US) and sham ESWT in the treatment of myofascial pain syndrome (MPS). [Subjects and Methods] Sixty MPS patients aged 18-60 years were included in the study. The patients were randomized equally into 3 groups. Group 1 received ESWT for 4 session with 3 day-intervals. Group 2 received 4 sessions of sham ESWT. US was applied to Group 3 for 10 sessions. All patients were recommended an exercise program. The patients were evaluated before-post and 6 weeks after treatment. Measurements were made using pressure pain threshold (PPT), pain score (PS) and visual analogue scale (VAS). Patients were evaluated by using SF-36 and HADS (hospital anxiety and depression scale). [Results] A significant posttreatment difference was found in VAS, PPT and SF-36 subparameters in group 1. In group 2, a significant difference was not found in any parameter. In group 3, a significant difference was detected in parameters of VAS and PPT. A significant difference was found between groups 1 and 2 as for subtitles of PPT, VAS, SF-36. [Conclusion] These results suggest that ESWT is as effective as US. ESWT and US are significantly more effective than sham ESWT.
