What is a TENS unit machine?
The TENS stimulates your central nervous system for relieving pain via the self-adhesive electrodes or pads which are placed on to the skin & fixed with the TENS unit with wires.
This stimulation is operated by a remote that is affixed with wires to the pads or electrodes.
Wireless TENS machines are also available in the marketplace for the convenience of the users. To sort out which wireless TENS machines can be the perfect choice for you, you can follow our article on the best wireless TENS unit.
A TENS unit can be a perfect preference for foot neuropathy or foot pain. A TENS unit is a pain reliever that works through the nerve stimulation process. Here we are going to tell you about the TENS unit placement for foot neuropathy.
How Do TENS Machines Work?
It is a 9-volt battery-operated tool that is considered to be benign & the alternative to non-addictive painkillers. A TENS machine works depending on two theories that relax your muscles.
- The Gate Control Theory: In this theory, the spinal cord closes & opens up the flow of electrical stimulation from the brain. The electrical frequencies constrain the transmission of the communication at the time of using the TENS machine; as a result, the pain signals are obstructed.
- Endorphin Releasing Theory: This theory involves stimulation of the electrical impulses to generate the production of encephalin & endorphins. These natural pain releasing chemicals act like morphine and block the pain signals. Although it is similar to drug therapy, it is out of drug-related side effects.
The two theories act as a great pain relief tool. The most straightforward adaptable settings of the TENS machine aids placing electrodes. Or pads at your specific painful area & to govern it according to your requirements.

“Neuropathy is a disease or dysfunction of one or more peripheral nerves, typically causing numbness or weakness.”
Neuropathy, also called peripheral neuropathy, affects the central nervous system, which is the combination of your brain & spinal cord. The way the neurons communicate with each other & with the brain is disrupted when nerve cells or neurons are damaged. It usually starts in the hands & feet. However, other parts of the body can be affected too.
- Causes of Neuropathy:
The causes of neuropathy or peripheral neuropathy cover:
- Physical trauma
- Repetitive injury
- Vascular and blood problems &
- Exposure to toxins

TENS therapy executes by fixing pads or electrodes to the feet or calves that transmit very small electrical pulses.
The electrical pulses help the muscle nerves in the feet & legs to shrink & expand at intervals. This process increases the flow of blood&interfere the pain signals of your body.
These pulses also enhance the production of pain, releasing a chemical named encephalin & endorphins in your feet & legs. The combination of these two chemicals blocks the pain signals.
As a result, you feel a mild pulsing sensation with some vibration in the soles of your feet when the TENS machine starts to work. Three types of machines are available in the marketplace for treating foot neuropathy:

TENS unit placement for foot neuropathy
The electrodes or pads are self-adhesive that generally placed over the area of pain or near to the pain spot. The TENS unit placement for foot neuropathy is important for getting relief from the pain of your feet & legs. Before discussing the TENS unit placement for foot pain, you need to know the general setting of TENS replacement.
- Mode Setting
- Standard: For ordinary use
- Burst: For chronic pain relief
- Modulation: For acute pain
- Pulse Rate (Frequency) Setting
The measurement of frequency is Hertz (Hz). Pain relief can occur at various frequencies. The following settings are suggested:
- 80-120Hz-acute pain
- 35-50Hz-muscle stimulation
- 2-10Hz -chronic pain
- Pulse Width Setting
Generally, pain releases with low to mid-time periods. Muscle stimulation needs a longer pulse width for the appropriate reproduction of a muscle contraction.
The period is too small. It's measured in microseconds that you may not notice the variance, but your nerves can.
The recommended Pulse Widths: 175-200uS. You can reinforce the power of your TENS machine by escalating the pulse width.
Duration of using a TENS Machine
- Acute pain:20-60min up to four times daily
- Chronic pain:20-30min up to five times weekly
