Kneehab XP adhesive electrodes conduct the signal from the unit to your quadriceps muscles. To maintain optimum conductivity between Kneehab XP and your quads, you will need to replace the adhesive electrodes every 4 to 6 weeks, depending on how often you use the unit.
This pack consists of a set of four replacement self adhesive electrode pads specifically designed for Kneehab XP.
