Ultrasound-Guided Intra-Articular vs Gluteal Intramuscular Corticosteroid Injection for Frozen Shoulder

Summary

The goal of this clinical trial is to determine if a gluteal muscle injection of compound betamethasone is as effective as an ultrasound-guided intra-articular injection in treating frozen shoulder (adhesive capsulitis) in adults aged 18 to 65. The main questions it aims to answer are: * Is gluteal injection as effective as ultrasound-guided intra-articular injection for improving shoulder function and reducing pain? * What are the side effects of each treatment method? Researchers will compare these two injection methods. Participants will: * Receive one injection at baseline and will be followed up for 12 weeks * Complete shoulder function assessments * Perform home rehabilitation exercises
