PTA internship opportunities are a chance to interact with patients under the supervision of full physical therapist assistants. In this role, you may follow a predetermined lesson plan, assist your supervisor with basic tasks, and otherwise learn the skills you should gain as a student. Interns rarely provide direct treatment to patients, but you may sit in on exams or physical therapy sessions and help record information about patient progress. Physical therapy assistant internships are most common in the summer, but you can usually find them throughout the year. This job should not be confused with parent-teacher association internships that help organize and manage matters for schools, despite sharing the same acronym.
