WORC is a disease-specific measure designed to be sensitive enough to detect the clinical improvement following non-operative or surgical treatment of rotator cuff pathology.
Raw Score = Sum of 21 VAS items (0-100mm)
Total Score = 0 (Normal) to 2100 (Worst disability)
Standardized Score (%) = [ (2100 - Raw) / 2100 ] x 100
