This article examines legal and ethical issues in the rehabilitation of the head-injured client, particularly the use of guardianship. Several models of rehabilitation goal setting are discussed, with a particular emphasis upon an educational model for the relationship between provider and client. Consistent with the educational model, questions are raised about the institution of legal guardianship given the dynamic changes that often occur in a head-injured client's competency during his or her rehabilitation course. The authors suggest changes in certain guardianship procedures that would interfere as little as possible with client growth and autonomy.
