| scleroderma clinical trial inclusion diagnosis | Criteria (item; subitem; weight/score) Skin thickening of the fingers of both hands extending proximal to the metacarpophalangeal joints (9) Skin thickening of the fingers (only count the highest score) puffy fingers (2) whole finger, distal to MCP (4) Finger tip lesions (only count the highest score) digital tip ulcers (2) pitting scars (3) Telangiectasia (2) Abnormal nail-fold capillaries (2) Pulmonary arterial hypertension and/or interstitial lung disease (2) Raynaud’s phenomenon (3) Scleroderma-related antibodies (any of anticentromere, antitopoisomeraseI [anti-ScL 70], anti-RNA polymerase III) (3) Add the maximum weight (score) in each category to calculate the total score. Patients having a total score of 9 or more are classified as having definite systemic sclerosis. Patients having a total score of 6-8 can be considered as having probable scleroderma, although this classification has not been evaluated. |

Myelopathy can be difficult to detect because it usually develops gradually. *(UMN)* |
