Why won’t my TENS 7000 electrode pads stick?
There are three main reasons that your TENS 7000 electrode pads fail to stick to your skin: there is debris from the skin on the electrode, the adhesive on the pad has dried out, or there is an excess of water and/or adhesive on the pad. Whatever the reason, electrode pads that do not adhere or that refuse to remain in place is a major problem. Why is that? Because trying to administer electrotherapy without electrodes is like beheading an Immortal when there isn’t any other Immortals around; all the energy from the Quickening simply dissipates and goes to waste. The electrodes channel the electrical current from the TENS unit and deliver it through the skin and onto the nerves.
Adhesiveness – or lack thereof – may also be a problem even if there is nothing wrong with the electrode pads. Natural barriers such as oils in the skin and hair may keep the pads from staying in place. To avoid this, the TENS 7000 manual recommends washing “the area of skin where you will be placing the electrodes, using mild soap and water before applying electrodes, and after taking them off. Be sure to rinse soap off thoroughly and dry skin well.” The manual also notes that “excess hair may be clipped with scissors; do not shave stimulation area.” Additionally, refrain from using creams, oils, lotions, or rubbing alcohol prior to affixing the electrodes – though it may be a good idea to rub skin lotion on the placement area when not wearing the electrode pads.
Reusable, self-adhesive pads could use a bit of water to extend the time during which they will remain sticky. According to the manual, “it may be helpful to improve repeated application by spreading a few drops of cold water over the adhesive and turn the surface up to air dry.” Careful, though; too much water will oversaturate the electrode pads and decrease their adhesiveness. Thus, instead of opening a faucet and holding the pads under the running stream, you’d do best by wetting the tip of a finger and applying moisture to the pad. Also remember that electrode pads do not fare well in hot and humid settings. An ideal environment would be a climate-controlled area with relatively low humidity.
When not in use, electrodes should be stored in a resealable bag and kept in a cool, dry place such as a refrigerator. Moreover, electrode pads should be disposed as soon as they lose their adhesiveness and TENS 7000 replacement pads ordered immediately. Better yet, keep an extra pair around and rotate the two sets so that both last longer.
