ABSTRACT
OBJECTIVE:
The aim of this study was to evaluate effect of pulsed radiofrequency (PRF) neuromodulation of suprascpaular nerve (SSN) in patients with chronic shoulder pain due to adhesive capsulitis and/or rotator cuff tear.METHODS:
The study included 11 patients suffering from chronic shoulder pain for at least 6 months who were diagnosed with adhesive capsulitis (n=4), rotator cuff tear (n=5), or adhesive capsulitis+rotator cuff tear (n=2) using shoulder magnetic resonance imaging or extremity ultrasonography. After a favorable response to a diagnostic suprascapular nerve block twice a week (pain improvement >50%), PRF neuromodulation was performed. Shoulder pain and quality of life were assessed using a Visual Analogue Scale (VAS) and the Oxford Shoulder Score (OSS) before the diagnostic block and every month after PRF neuromodulation over a 9-month period.RESULTS:
The mean VAS score of 11 patients before PRF was 6.4+/-1.49, and the scores at 6-month and 9 month follow-up were 1.0+/-0.73 and 1.5+/-1.23, respectively. A significant pain reduction (p<0.001) was observed. The mean OSS score of 11 patients before PRF was 22.7+/-8.1, and the scores at 6-month and 9 month follow-up were 41.5+/-6.65 and 41.0+/-6.67, respectively. A significant OSS improvement (p<0.001) was observed.CONCLUSION:
PRF neuromodulation of the suprascapular nerve is an effective treatment for chronic shoulder pain, and the effect was sustained over a relatively long period in patients with medically intractable shoulder pain.Palabras clave
