According to regulations, a PTA must:

The requirement for a physical therapist assistant (PTA) to have on-site direct supervision by a physical therapist (PT) is grounded in the regulations governing the practice of physical therapy in Ohio. This provision ensures that patient care is delivered safely and effectively, as the supervising PT is responsible for overseeing the PTA's activities and ensuring adherence to established treatment plans.

Having on-site supervision allows the PT to provide immediate feedback, guidance, and support during patient treatment sessions. This collaborative approach is vital in maintaining the quality of care and ensuring that the PTA is operating within their scope of practice. It also facilitates ongoing assessment and adjustments to treatment strategies based on the patient's progress or any changes in their condition.

In contrast, the other options do not align with the regulatory framework for PTAs. Responsibilities related to evaluations and discharge summaries, insurance claims, and patient billing typically fall outside the PTA's scope of practice or require direct oversight from a licensed PT. The requirement for direct supervision reinforces the collaborative nature of patient care in physical therapy and emphasizes the importance of maintaining patient safety and adherence to treatment protocols.
