Notch vs Midpoint Suprascapular Nerve PRF for Chronic Shoulder Pain

Recruiting now · Not applicable

Conditions studied: Chronic Shoulder Pain, Rotator Cuff Tendinopathy

In brief

This study aims to compare the effects of pulsed radiofrequency (PRF) treatment of the suprascapular nerve using suprascapular notch and midpoint approaches on pain, shoulder function, and muscle strength in patients with chronic shoulder pain due to rotator cuff tendinopathy. Patients will be randomly assigned to one of the two intervention groups. Clinical evaluations will include pain assessment using the Numeric Rating Scale (NRS), functional assessment using the Shoulder Pain and Disability Index (SPADI), and quality of life assessment using the Short Form-36 (SF-36). In addition, shoulder range of motion will be measured goniometrically, muscle thickness of the supraspinatus and infraspinatus will be evaluated by ultrasonography, and shoulder muscle strength will be assessed using an isokinetic dynamometer. Assessments will be performed at baseline, 24 hours, 1 month, and 3 months after the intervention. The results of this study are expected to provide evidence regarding the optimal approach for PRF treatment of the suprascapular nerve in patients with chronic shoulder pain.
