When supervising assistive personnel, how many of them can be physical therapy assistants (PTAs)?

In Arizona, the supervision of physical therapy assistants (PTAs) is governed by specific regulations that outline how many PTAs a licensed physical therapist can supervise at one time. The law stipulates that a physical therapist can supervise no more than one PTA at a time. This regulation is in place to ensure that the supervising therapist can adequately oversee the treatment and maintain the quality of care being provided to patients.

This limitation is crucial because it aims to promote patient safety and ensure that the supervising physical therapist can effectively monitor and support the PTA in their clinical activities. When there are multiple PTAs working under a single therapist, it can hinder the ability to provide appropriate oversight, potentially compromising the quality of care. This is why the correct answer states that only one PTA can be supervised by a physical therapist at any given time in Arizona.
