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.",[79,80],"Chronic Shoulder Pain","Rotator Cuff Tendinopathy",[82,83,79,80,84,85,86],"Suprascapular Nerve","Pulsed Radiofrequency","Isokinetic Muscle Strength","Ultrasound Measurement","Shoulder Function","2026-06-26",{"date":89,"type":90},"2026-06-30","ACTUAL",{"date":92,"type":90},"2026-05-07",{"date":94,"type":73},"2027-08-30",{"name":5,"class":6},1]
