Randomized Controlled Trial
Efficacy of Perineural Dexmedetomidine in Ultrasound-guided Interscalene Block on Rebound Pain after Shoulder Arthroscopy.
This prospective, randomized, double-blind trial was performed to investigate the effect on rebound pain incidence of mixing dexmedetomidine (DEX) with local anesthetics in a combined injection interscalene block (ISB) during shoulder arthroscopy. ⋯ Perineural DEX added to ISB exerts a beneficial effect on the incidence of rebound pain after ISB in patients undergoing shoulder arthroscopy. Perineural DEX facilitated the implementation of multimodal analgesia in the early stage after operation.

Randomized Controlled Trial Comparative Study
Study on the Effectiveness of Ultrasound-guided Pulsed Radiofrequency Therapy for Shoulder Pain Caused by Trigger Points.
This study compares ultrasound-guided pulsed radiofrequency (UG-PRF) with ultrasound-guided dry needling (UG-DN) for treating painful shoulder periarthritis (PSP). ⋯ Both UG-PRF and UG-DN therapy are effective treatments for PSP, with UG-PRF showing better results in reducing pain and improving shoulder mobility.
