What best describes the difference between a physical therapist (PT) and a physical therapy assistant (PTA) in terms of scope of practice and supervision?

• A. PTA develops plan of care; PT implements components under supervision; supervision varies by setting; PT supervises.
• B. PT develops plan of care; PTA implements components under supervision; supervision varies by setting and jurisdiction; PT supervises.
• C. PT and PTA have identical scopes of practice and supervision is always the same.
• D. PT only does diagnosis; PTA only does billing.

Answer: (B)

In physical therapy, the main idea is that the physical therapist designs the plan of care and provides the overall supervision, while the physical therapy assistant carries out components of that plan under supervision. The therapist performs the initial evaluation, determines the diagnosis and prognosis, and develops the plan of care. The assistant then implements parts of that plan—delivering treatment components and activities as directed by the plan—under the supervising therapist. Supervision requirements aren’t fixed; they vary by the clinical setting (like outpatient vs. hospital) and by state or provincial regulations, so the supervising PT must adapt accordingly. This is why the option that states the PT develops the plan, the PTA implements components under supervision, supervision varies by setting and jurisdiction, and the PT supervises is the best choice. The other descriptions mix up roles or claim identical scopes and universal supervision, which aren’t accurate, and they misstate who handles diagnosis or billing.
