Chronic shoulder pain is a highly prevalent musculoskeletal problem that significantly restricts daily activities and diminishes the patient's quality of life. While conservative treatments and various interventional injections are widely used, long-term efficacy can be limited, and systemic side effects may occur. The shoulder PENG block is a novel regional analgesia technique that specifically targets the articular (sensory) branches of the nerves innervating the shoulder joint capsule without affecting the motor branches. In this single-center study, a total of 45 eligible adult patients with chronic shoulder pain who did not respond to conservative medical treatments will receive an ultrasound-guided PENG block as part of their routine clinical care. The procedure will be performed under sterile conditions using a combination of local anesthetic (lidocaine) and dexamethasone. Patient pain levels will be assessed using the Numerical Rating Scale (NRS), shoulder disability and functional status will be measured using the Shoulder Pain and Disability Index (SPADI), and overall patient satisfaction will be evaluated using the Global Perceived Effect (GPE) score. All parameters will be documented at baseline (before the procedure) and at follow-up visits on the 1st week, 4th week (1 month), and 3rd month post-procedure. The investigators aim to determine the efficacy, duration of effect, and safety profile of this intervention.",[68,69,70,71,72],"Chronic Shoulder Pain","Pericapsular Nerve Group Block (PENG Block)","Frozen Shoulder","Bursitis","Rotator Cuff Disorders",[74,75],"shoulder pain","pericapsular nerve group block","NOT_YET_RECRUITING","2026-05-21",{"date":79,"type":80},"2026-05-26","ACTUAL",{"date":82,"type":62},"2026-06-01",{"date":84,"type":62},"2026-10-15",{"name":5,"class":6},1]
