Most of my clients are solo practioners or smalll medical clinics. There are a number of doctors who run their offices with FileMaker, some of who are on TechNet, but there have been some who were developing for others that have sought help in this forum. I find most physicians have specific criteria they wish to follow which plays well into FileMaker's strengths. There are a couple who sell (or give away) medical practice dbs that are created in FMP.
To followup on David's suggestion google FileMaker physical therapy. You'll get hits aplenty.
Did you have a particular question or were just seeing if it could be/was being done.
