A Physical Therapist Assistant (PTA) works under the supervision of a physical therapist to provide patient care, implement treatment plans, and document progress. Responsibilities include performing tests, modifying treatments, instructing patients and caregivers, and ensuring safety and compliance. PTAs must maintain clinical competencies, provide high-quality customer service, and participate in educational programs. The role requires physical dexterity, the ability to lift up to 40 lbs, and adherence to safety protocols. An associate degree in PTA and CPR certification are required, along with preferred experience in an outpatient setting.
