Evaluation of limited hand mobility in systemic sclerosis patients by using "prayer sign" and "tabletop sign".

In our study, it was found that LJM staging correlated with mRss and dcSSc patients had more severe LJM findings than lcSSc. We conclude that "prayer sign" and "tabletop sign" tests used in hand evaluation in SSc patients have similar clinical results with mRss and can be simple bedside tests in daily practice. Key Points • This is the first study examining limited joint mobility (LJM) with "prayer sign" and "tabletop sign" tests in systemic sclerosis (SSc) patients. • "Prayer sign" and "tabletop sign" tests can be easily performed in daily practice. • We found Rosenbloom LJM staging correlated with modified Rodnan skin score. LJM of the hand can be a good prognostic indicator for early stage SSc patients.
