Effect of pulsed radiofrequency to the suprascapular nerve (SSN) in treating frozen shoulder pain: A randomised controlled trial.

Background: Treatment for frozen shoulder (FS) focuses on pain control and restoring movement and strength through physical therapy. We aimed to evaluate the efficacy of pulsed radiofrequency (PRF) lesioning of the suprascapular nerve for the treatment of FS pain.

Methods: Forty patients with FS were enrolled and randomly assigned into the intervention group (n = 20) that received PRF and a control group (n = 20) which received medical treatment (NSAIDs).
