How is the mRSS calculated?

Examiner palpates 17 areas (face, anterior chest, abdomen, upper arms, forearms, hands, fingers, thighs, legs, feet) grading each 0 (normal) to 3 (severe thickening). Maximum score is 51. Score >20 indicates diffuse cutaneous SSc with higher organ risk.

What is the clinical significance of mRSS in SSc?

mRSS predicts mortality and internal organ involvement. Rapid early skin progression correlates with renal crisis and ILD risk. mRSS is a primary endpoint in SSc clinical trials and declines with effective therapy.
