ZMPCZM016000.11.06 TENS Vs IFC

  1. 1. TENS VS INTERFERENTIAL CURRENT (IFC) WHAT IS THE DIFFENCE BETWEEN TENS AND IFC?  TENS RUNS ON A LOW FREQUENCY AT 1000hz or less  IFC RUNS ON A HIGHER FREQUENCY AT 1000-10,000 hz . ZYNEX IFC DEVICE IS SET AT A 4000hz CARRIER FREQUENCY. HOW DO YOU EXPLAIN THE DIFFENCE BETWEEN THE TWO CARRIER FREQUENCIES?  TENS DELIVERS MOST OF THE STIMULATION UNDER THE ELECTRODE OR SUPERFICIALLY (UNDER THE SKIN) THE CARRIER FREQUENCY CAN RANGE BETWEEN 1-150 hz. MUCH LOWER THAN IFC RANGE. TENS IS LOW FREQUENCY.  IFC CURRENT PENETRATE DEEPER INTO THE TISSUE BECAUSE THE CARRIER FREQUENCY IS SET AT 4000hz . MUCH HIGHER THAN TENS. IFC CONCENTRATES AT THE POINT OF INTERSECTION ( WHEN WE CROSS THE LEAD WIRES) BETWEEN THE ELECTRODES. THIS CONCENTRATION OCCURS DEEP IN THE TISSUE AS WELL AS AT THE SURFACE OF THE SKIN. IFC IS MEDIUM TO HIGH FREQUENCY.  IFC SKIN RESISTANCE DECREASES AS PULSE FREQUENCY INCREASES. FOR EXAMPLE , AT A DEEPER FREQUENCY OF 4000hz CAPACITIVE SKIN RESISTANCE IS EIGHTY TIMES LOWER THAN WITH A FEQUENCY OF 50hz
