In the July 2012 issue, PTJ published 2 papers investigating the effects of different electrotherapeutic interventions--transcutaneous electrical nerve stimulation (TENS) and interferential therapy (IFT)--on pain. In this discussion podcast, two of the authors, Myrto Dounavi and Kathleen Sluka, are joined by moderator Steven George and Meryl Gersh to discuss their studies as well as the larger issues of adequate dosing and the effect of mechanism of action on dosing.
