In his Mary McMillan Lecture from 2017, Richard Shields, PT, PhD, FAPTA, uses the term “precision physical therapy” in his discussion of how movement is an important regulator of genetic and epigenetic factors influencing the health.

"As a physical therapist, I believe that we change time. We routinely turn over the hourglass and give patients a new lease on life. Quite simply, our interventions … are powerful regulators of genes that activate the energy systems that can reduce the rate that cells and tissues age."
