As an international physical therapy assistant, you travel overseas to assist rehabilitation and perform other duties related to physical therapy treatment under the direction of a licensed physical therapist (PT). Physical therapy assistants may work in a healthcare clinic, at a fitness center, or in an industrial workplace. You work with a patient or client to alleviate medical issues that limit their ability to move or perform daily activities. As a PTA, you guide the patient through movements and exercises, and measure progress and changes in performance. Working internationally allows you to experience new places while helping people with health-related conditions.
