No results posted yet for this study

Summary

Background: The suprascapular nerve block is frequently used to treat chronic shoulder pain. The nerve blockade provides probably only a short-term relief, and more compelling approaches have been investigated. Pulsed radiofrequency stimulation of suprascapular nerve has been reported as safe and reliable method for pain treatment. However, formal efficacy study for pRF stimulation of the shoulder joint has not been published. Evidence-based validation of a new method is necessary for both scholastic and practical purposes.

Methods: This study is a randomized active controlled blind trial. Lidocaine injections alone and pRF stimulation with two different combinations will be performed. Participants will be followed during 6 months, and subjective and objective outcome variables will be recorded. Patients are randomly allocated for suprascapular nerve block (n=50), for suprascapular nerve pRF stimulation (n=50) or for both suprascapular nerve blocks and humeroscapular joint pRF stimulation (n=50). All patients will receive standardized physical therapy at the unit of physical medicine and rehabilitation.

Results: Pulsed radiofrequency is thought to be a non-neurolytic neuromodulation method with some effectiveness in relieving of both experimental and clinical neuropathic pain. Our earlier results suggest additional therapeutic benefit obtained when pRF was performed in addition to physiotherapy (TAU). In a review, Chan et al. (2016) concluded that SSNB treatment could be more effective in treating pain in patients with longstanding rheumatoid arthritis when compared to intra-articular injection of corticosteroid. Also short-term pain reduction occurred in patients with chronic rotator cuff lesions. With regard to adhesive capsulitis, SSNB treatment showed a greater effect in relieving pain but on functional outcome, the results were inconclusive.

Discussion: In summary, this study investigate effects of pRF for patients with chronic shoulder pain from arthritis, frozen shoulder and/or degenerative shoulder disease. PRF can be performed in an outpatient department and provides the clinician with an alternative or additional approach to oral drug treatment and intra-articular injection. Further, it may prove to be a useful treatment for patients who are unfit or unwilling to consider surgical intervention.
