With physical therapist assistants (PTAs) performing patient interventions under the direction of a physical therapist, you need to know how to read and understand a research article to provide the best possible patient care. The PTA must have a reasonable grasp of current evidence to communicate knowledgeably with the therapist, the patient, and other health-care providers. This text provides the information and skills you need to actively participate in evidence based practice. You'll enter the world of the clinic with confidence.
