Final answer:
Physical Therapist Assistants are not typically responsible for the evaluation or re-evaluation of patients; these tasks are performed by a licensed Physical Therapist. However, PTAs can assist by collecting data and providing observations to the PT.
Step-by-step explanation:
A Physical Therapist Assistant (PTA) may participate in certain aspects of the patient care process, but the evaluation and re-evaluation of patients is typically not within their scope of practice. According to the American Physical Therapy Association (APTA), it is the responsibility of the licensed Physical Therapist (PT) to perform the initial evaluation, establish a diagnosis, and create a plan of care. The physical therapist also conducts re-evaluations as required. However, a PTA may contribute to this process by collecting data and providing observations to the PT during the course of treatment. Note that laws and regulations vary by state, so PTAs should always adhere to their state's practice act regarding their roles and responsibilities.
