Evaluation of the Effectiveness of Pericapsular Nerve Group Block in Hemiplegic Shoulder Pain
Sponsor: Marmara University
Summary
Hemiplegic shoulder pain (HSP) is a common and clinically significant complication after stroke that negatively affects rehabilitation outcomes. It is associated with shoulder subluxation, capsular contracture, spasticity, and central pain mechanisms, leading to pain, limited range of motion, and reduced quality of life. The suprascapular nerve (SSN) block has been shown to be effective for shoulder pain management; however, the glenohumeral joint (GHJ) receives innervation from multiple nerves including the axillary, subscapular, and lateral pectoral nerves. The recently described pericapsular/periarticular nerve group (PENG) block targets these articular branches and may provide analgesia with minimal motor impairment. This study aims to evaluate the effects of adding an ultrasound-guided PENG block to conventional physical therapy in patients with post-stroke hemiplegic shoulder pain, focusing on pain intensity, range of motion, and quality of life outcomes.

Ultrasound-Guided Pericapsular/Periarticular Nerve Group (PENG) Block
Under real-time ultrasound guidance, a 100-mm needle is advanced in-plane between the deltoid muscle and the subscapularis tendon with the patient in the supine position and the affected arm externally rotated and abducted at approximately 45 degrees. A total of 10 mL of 0.25% bupivacaine hydrochloride combined with 4 mg of dexamethasone is injected slowly into the pericapsular space to provide analgesia to the glenohumeral joint.
