I don't know if I'm stating the obvious, but "Google" 'caring for patient with Scleroderma'.
For instance, I found this link to a Johns Hopkins site:

The answer to your question is going to be what symptoms they present and go from there. As one of the items in the article talks about, increased dental care may be needed if they have dry mouth and eyes. If they are experiencing weakness, a regular ambulation schedule may be in order.
If joint pain is present, making sure there is adequate padding may be called for.
Etc. Sorry, no personal experience with this....
