Effectiveness Of Shock Wave Therapy Versus Intra-Articular Corticosteroid Injection In Diabetic Frozen Shoulder Patients' Management: Randomized Controlled Trial

Featured ApplicationAdhesive Capsulitis is one of the most common, yet challenging clinical disorders presenting to the orthopedic surgeon. Shock wave therapy was demonstrated as a conservative intervention that provides good results for the treatment of frozen shoulder. Although injection of corticosteroids is an invasive procedure but associated with many risks. This study aimed to investigate the effectiveness of shock wave versus intra-articular corticosteroid injection with evaluation of their side effects.Frozen shoulder is a major musculoskeletal illness in diabetic patients. This study aimed to compare the effectiveness of shock wave and corticosteroid injection in the management of diabetic frozen shoulder patients. Fifty subjects with diabetic frozen shoulder were divided randomly into group A (the intra-articular corticosteroid injection group) and group B that received 12 sessions of shock wave therapy, while each patient in both groups received the traditional physiotherapy program. The level of pain and disability, the range of motion, as well as the glucose triad were evaluated before patient assignment to each group, during the study and at the end of the study. Compared to the pretreatment evaluations there were significant improvements of shoulder pain and disability and in shoulder flexion and abduction range of motion in both groups (p < 0.05). The shock wave group revealed a more significant improvement the intra-articular corticosteroid injection group, where p was 0.001 for shoulder pain and disability and shoulder flexion and abduction. Regarding the effect of both interventions on the glucose triad, there were significant improvements in glucose control with group B, where p was 0.001. Shock waves provide a more effective and safer treatment modality for diabetic frozen shoulder treatment than corticosteroid intra-articular injection.
