For most patients who are given a tens, transcutaneous electrical nerve stimulator, or an Infrex Plus combination interferential and tens unit, the biggest concern is where do I put the electrodes. Most patients would prefer a "cookbook" approach to the exact placement but due to the nature of pain one placement on day one may not be sufficient for pain control at a later day.
In this video Bob Johnson explains the logic behind Infrex and tens electrode placement for maximum pain relief. Without having to use a cookbook approach the logic behind why electrodes are placed where, and what outcome is expected is explained.
The video is not specific to any particular tens, interferential, pulsed galvanic, or microamperage unit but gives the general knowledge a professional would bring to explain how to place the electrodes for maximum pain relief.
