Physical therapist uses evaluation and clinical reasoning process to provide evidence-based intervention in clinical environment. If clinical practice guideline is lacking, the intervention is decided based on preference of physical therapist while patient has no chance to involve it. In comparison to informed consent which is a one-way direction; shared decision making is an interaction between professional provider and patient. Professionals provide enough information. At the same time, patient provides personal thinking and considerations. The clinical decision was made after discussion between professional and patient. In this paper, we will use shared decision-making process in physical therapy to deal with chronic pain.
