Which of the following actions would a PTA be prohibited from doing?

A physical therapist assistant (PTA) is specifically trained to assist physical therapists in providing care but has limitations on the scope of practice. Establishing a new treatment plan falls outside the PTA's authorized responsibilities. Treatment plans must be created and supervised by a licensed physical therapist, as they require critical clinical decision-making based on the overall assessment of the patient's condition, history, and treatment goals.

In contrast, conducting patient evaluations is reserved for physical therapists, but PTAs can implement treatment interventions as directed by the physical therapist. Similarly, supervising patient aides can fall within a PTA’s responsibilities as they support the care provided under the supervision of a licensed professional. Documenting treatment sessions is also within the PTA’s scope, as they can record observations and progress as part of the continuum of care managed by a physical therapist. These roles emphasize the collaborative nature of physical therapy practice while underscoring the need for the licensed therapist to remain central to the development and adjustment of treatment plans.
