If you agree to take part in this study, you will be asked 6 questions. The first 2 questions ask about your physical ability to walk up and down stairs. The next 4 questions ask about your history of falling down in the last year, symptoms of depression, loss of urinary control, vision problems, and your ability to function physically. If you report that you have fallen down more than 3 times in the last year, you will automatically be referred for a physical therapy evaluation at M. D. Anderson.
