Overview
Brief Summary
Comparative study between pulsed radiofrequency in suprascapular nerve or bupivacaine block for chronic shoulder pain
Detailed 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.

Eligibility Criteria
Inclusion Criteria
- •Age over 18 years old
- •Chronic shoulder pain (more than 3 months)
- •Clinical and imaging diagnosis: rotator cuff injury, adhesive capsulitis, supraspinatus, tendinopathy, bicipital tendinitis, impingement syndrome, subscapularis tendinopathy, , subacromial and subdeltoid arthrosis, acromioclavicular arthrosis, subdeltoid subacromial bursitis
- •Pain intensity ≥4 on movement, on a numerical scale from zero to 10 (where zero means no pain and 10 the most intense pain imaginable).
Exclusion Criteria

Arms & Interventions
Pulsed Radiofrequency
The investigators performed pulsed radiofrequency in the suprascapular nerve
Intervention: Pulsed radiofrequency
Bupivacaine
The investigators performed a blocade with bupivacaine in the suprascapular nerve.
Intervention: Suprascapular nerve block with bipuvacaine
Outcomes
Primary Outcomes
Comparison of pain intensity after application of pulsed RF in the suprascapular nerve versus injection of a local anesthetic.
Time Frame: 12 months
Comparison of pain intensity after application of pulsed RF to the suprascapular nerve and after injection of a local anesthetic. The numerical pain scale (Visual Analogue Scale - VAS) at rest and during movement was used. This scale (VAS) ranges from 1 to 10, with 1 representing mild pain and 10 representing severe pain.
Secondary Outcomes
- Need for additional analgesic.(12 months)
- To assess the range of motion of the shoulder joint(12 months)
- Duration of the analgesic effect.(12 months)
