简要总结
The purpose of this prospective, observational study is to evaluate the clinical and functional outcomes of ultrasound-guided Pericapsular Nerve Group (PENG) block in patients suffering from chronic shoulder pain. 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.
详细描述
Study Design and Setting:
This is a prospective, observational, and single-center clinical study designed to evaluate the clinical and functional outcomes of ultrasound-guided Pericapsular Nerve Group (PENG) block in patients with chronic shoulder pain. The study will be conducted in accordance with the Declaration of Helsinki, and approval from the local clinical research ethics committee will be obtained prior to patient enrollment.
Patient Selection:
Adult patients (aged over 18 years) presenting with chronic shoulder pain lasting longer than 3 months, who have an initial Numerical Rating Scale (NRS) score greater than 4 and have not responded to conservative or medical treatments, will be screened for eligibility. Written informed consent will be obtained from all participating individuals. Patients with coagulation disorders, psychomotor disorders, active infections at the injection site, a history of shoulder surgery within the past 6 months, or known allergies to local anesthetics or corticosteroids will be excluded.
