The Ohio Physical Therapy Practice Act allows physical therapy to be rendered under all of the following EXCEPT:

The Ohio Physical Therapy Practice Act outlines specific conditions under which physical therapy can be provided, and one of those conditions is the requirement for proper referral from credentialed health care providers. While physical therapy can indeed be accessed through referrals from various licensed practitioners, such as licensed physicians and dentist as outlined in the Act, a referral from a licensed athletic trainer is not included among the recognized sources.

Athletic trainers focus primarily on injury prevention, rehabilitation, and performance enhancement in athletic contexts rather than the broader medical management of patient care that would necessitate a referral for physical therapy. This lack of authorization similarly holds for the scenario presented in the question, indicating that athletic trainers do not have the authority to recommend physical therapy services through a formal referral process as other health professionals do.

Thus, the Act does not support physical therapy being rendered on the basis of a referral from a licensed athletic trainer, making this the correct understanding among the choices presented.
