The job duties of an international occupational therapy assistant (OTA) involve helping patients with their treatment program in an overseas location. As an OTA who works abroad, you help each patient with their daily therapy activities, which may include things like stretching, strength and range-of-motion exercises, and motor skills improvement drills. You handle your responsibilities under the direct supervision of an occupational therapist (OT). Your goal with each client is to help them recover from their illness or injury or help them learn to handle daily activities with a disability or limitation. You typically live in another country during the length of your assignment.
