The caption under the pic of her in the hospice? Is this after 1990? I was unaware that she was sitting upright on her own. In that pic she looks very normal.
I believe that pic is post trauma. You can see that one of her hands is contracted and she has a pillow under her arm. It appears that she is sitting in front of a gift shop.
All pictures are after her stroke and some are very early!
According to Mark Fuhrman in his new book about the case, "Silent Witness - the Untold Story of Terri Schiavo's Death" (William Morrow - 2005), early after her collapse Michael Schiavo had nurses put makeup on her and fix her hair. After he won that medical malpractice suit, according to Fuhrman, he abandoned all efforts to give her therapy, even going so far as to say no to treating her sepsis infections (he had to give in here because the law said so).
