In this ethics legal column, we explore advance directives (ADs), the prototypical means for individuals in the United States to document their wishes for future treatment or nontreatment. I have invited Preya S. Tarsney, JD, to be the guest editor of this collection. Her scholarly interests include informed refusals, negotiation and mediation in clinical rehabilitation, and best practices in ethics consultation. Ms. Tarsney is a senior bioethicist at the Shirley Ryan AbilityLab, a lecturer of physical medicine and rehabilitation (PM&R) at Northwestern University Feinberg School of Medicine, and faculty lecturer at the MacLean Center for Clinical Medical Ethics at the University of Chicago. As always, I welcome ideas and reactions to the PM&R ethics/legal column at
