Efficacy of extracorporeal shock wave combined with ultrashort wave in the treatment of patients with frozen shoulder

Abstract

Objective To investigate the clinical efficacy of extracorporeal shock wave combined with ultrashort wave in the treatment of frozen shoulder. Methods Seventy-eight patients with frozen shoulder were randomly divided into ultrashort wave group, shock wave group and combination group, 26 cases in each group. The patients in each group received the active training of shoulder joint, such as climbing exercise. Constant-Murley shoulder joint function evaluation scale, including pain score, muscle strength score, range of motion score, daily life ability score and the total score was used to evaluate the shoulder joint function in the three groups before treatment and at 7 weeks after treatment. Results The scores of patients’ shoulder joint function, such as pain, muscle strength, range of motion, daily life ability and the total score in each group, were significantly improved at seven weeks after treatment compared with pretreatment, which were statistically significant (P<0.05) . The range of motion score, the daily life ability score and the total score in shock wave group were higher than that in ultrashort wave group (P<0.05) . The scores in combination group, such as pain, muscle strenth, range of motion, daily life ability and the total score were higher than that in shock wave and ultrashort wave group. The differences were statistically significant (P<0.05) . Conclusion Extracorporeal shock wave combined with ultrashort wave can significantly relieve the pain of frozen shoulder, improve the activity of the joint, enhance the muscle strength and daily life ability.
