This video is a very good display of Carol's technique and the skill she uses with all her clients. Short clips have been added to the original to illustrate how difficult it is for Bill to perform mundane tasks. A DVD disc of this video is used to display Bill's symptoms to doctors who examine him. Since Bill does not always display the same symptoms during an office visit, Carol captured them on a day when they were clearly visible. Most doctors really appreciate having the video, as a picture tells them so much more than a few minutes in the examination room.
