(1) Appropriate, skilled physical therapy treatment is treatment which is reasonable in terms of accepted physical therapy practice, and necessary to recovery of function by the patient. The use of a nontraditional treatment by itself shall not constitute unprofessional conduct, provided that it does not result in injury to a patient or create an unreasonable risk that a patient may be harmed.

(2) Appropriate physical therapy services must be of such a level of complexity and sophistication, or the condition of the patient must be such, that the services required can be safely and effectively performed only by a physical therapist or physical therapist assistant under supervision of a physical therapist.
