Note: With proper care, electrodes can be reused for over 20 applications. We recommend purchasing Pre-TENS electrode spray, additional electrodes and rechargeable batteries with your tens unit.
Low Frequency: The lower frequencies, 2-5 Hz, are believed to cause the body to react. The reaction creates natural painkillers, or endorphins. The endorphins block the pain naturally and while popular, this isn't the usual method of using TENS.
High Frequency: For more intense pain, higher frequencies, 90-130 Hz, work to actually interrupt those pain signals being sent to the brain. This is the most common use for the machine and while you start slow, it's not uncommon to need to up the frequency to find the best block.
