As a common belief among rehabilitation specialists, the purpose of rehabilitation has been restoring some of a person's physical and mental capabilities that have been lost as a result of disease, illness, or injury and to help achieve the highest possible level of function, independence, and quality of life. Goals of rehabilitation for different populations differ. Older adults usually focus on recovery of self-care ability and mobility, while for younger persons reentering the work force or returning to school may be the goal. Many factors influence the choice of who would benefit from rehabilitation and the success of those rehabilitation efforts. Much experimental and theoretical work has been done so far in the choice for rehabilitation. To address these needs, fourteen papers that focused on rehabilitation services and the choice for better services has been selected for this issue. In this issue of Iranian Rehabilitation Journal, articles focus on mental health, aged issues, addiction rehabilitation and some factors which influence choosing rehabilitation services.
