What was the primary stipulation regarding aides employed by or assisting a PT before the 1973 amendments?

The primary stipulation regarding aides employed by or assisting a physical therapist before the 1973 amendments was that they could continue performing duties if they were employed prior to the amendments. This provision allowed those individuals who had been working in the capacity of an aide prior to the legislative changes to maintain their roles without having to meet new educational or licensing requirements that were introduced later. The amendments were aimed primarily at establishing more stringent guidelines for the practice of physical therapy, but they recognized the existing workforce and allowed continuity for those aides already in employment. This transitional measure was essential in ensuring that experienced personnel could keep contributing to patient care without disruption as new standards were phased in.
