About

Comparative study between pulsed radiofrequency in suprascapular nerve or bupivacaine block for chronic shoulder pain

Full description

Prospective, randomized, comparative study of 40 participants with chronic shoulder pain allocated into two groups. Patients in group 1 underwent pulsed RF (180sec, with a fixed temperature at 42C, twice) on the suprascapular nerve, and the other group, 2, underwent nerve block with bupivacaine (5ml). After the procedure, patients were evaluated for 3 months regarding pain intensity, shoulder range of motion and dose of rescue opioids.
