A comparison of the effectiveness of therapies for frozen shoulder (FS): mobilization with continuous interscalene block (CISB) and mobilization with intra-articular steroid injection (IASI)

Background: Frozen shoulder (FS) can cause significant discomfort and limited range of motion for the affected individual. Early and painless mobilization of the shoulder has been shown to yield positive results in treating the condition.Objectives: The aim of this study was to evaluate and compare the effectiveness of two therapies for frozen shoulder (FS): mobilization with continuous interscalene block (CISB) and mobilization with intra-articular steroid injection (IASI). Specifically, we aim to determine the effectiveness of both interventions in improving clinical and functional outcomes and to evaluate the impact of adding IASI to mobilization with CISB.Methods: We conducted a prospective comparative study. The participants were divided into three groups of ۲۰ patients each. The distribution was performed by simple randomization. The primary outcomes of pain and patient satisfaction were assessed using VAS scores. Outcome measures such as pain, patient satisfaction, range of motion, and UCLA scores within groups were assessed.Results: The majority of patients were women. There was a significant improvement in early pain relief and range of motion in patients treated with mobilization in the CISB setting. Late functional outcomes were similar in all groups, regardless of treatment modality. IASI did not have a significant impact on the early or late outcomes of CISB mobilization.Conclusion: Mobilization under CISB provides early pain relief, improvement in range of movements, and good long-term functional results for frozen shoulders. IASI has no effect on early pain relief or improving range of motion.
