Primary outcomePrimary: Change of Shoulder Pain and Disability Index (SPADI) — 22.1; 25.9; 27.0; 36.6 score on a scale
Summary
The aim of this study is to compare the efficacy and safety of the suprascapular nerve block (SSNB) at the spinoglenoid notch with SSNB at the suprascapular notch, which is the most commonly used technique in patients with chronic shoulder pain.
