Modified Rodnan Skin Score (mRSS)
Modified Rodnan skin score (Clements 1995): skin thickness graded 0–3 at 17 body sites gives a 0–51 total; a higher score marks more extensive skin involvement in systemic sclerosis.

What the result means
- 0-51
- Skin thickness graded 0-3 at 17 body sites. Higher scores indicate more extensive skin involvement in systemic sclerosis. A severity measure, not a treatment order.
