Transcutaneous Electrical Nerve Stimulation (TENS) is a therapeutic approach that uses a mild electrical current to activate peripheral nerves for pain relief. TENS units are small, lightweight, and often battery-powered devices that deliver electrical currents at or near nerves to block or change the user's perception of pain. Before using a TENS unit, it is important to consult a healthcare provider to determine the right device and application method for your needs. The skin should be clean and dry, and the unit should be turned off before placing the electrode pads. Once the pads are secure, the user can turn on the machine and adjust the settings to a comfortable intensity, being careful not to increase the intensity too much, which could cause discomfort.

TENS units are safe for most people but should not be used by those with pacemakers, epilepsy, or during pregnancy
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive method of pain relief that uses low-voltage electrical currents to block or change the user's perception of pain. TENS units are generally safe for most people, but there are some exceptions.
People with pacemakers should not use TENS units as the electromagnetic waves generated by the units can interfere with the functioning of pacemakers. Similarly, the electrical charges from TENS units can cause an abnormal burst of electrical energy in the brain of someone with epilepsy, potentially triggering a seizure, especially when the electrodes are applied to the head, neck, or shoulders.
Pregnant women should also avoid using TENS units, particularly during the early stages of pregnancy, as it may cause unintended uterine contractions and potentially induce early labor. Furthermore, it is important to avoid placing the electrodes near damaged skin, rashes, or open wounds, as this may increase pain and damage tissue.
It is always advisable to consult a healthcare provider before using a TENS unit to ensure it is safe and suitable for your individual needs. They can provide guidance on the specific device to use and how to apply the electrodes correctly.

The machine uses a mild electrical current to stimulate nerves and block pain signals
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive method of pain relief that uses a mild electrical current. TENS units are small, portable devices that deliver electrical impulses through the skin to block pain signals and change your perception of pain.
TENS machines work by passing a weak electrical current to your nerves, which can help to ease pain. The electrical impulses flood the nervous system, reducing its ability to transmit pain signals to the spinal cord and brain. This changes the way you perceive pain, providing temporary relief.
The electrical impulses from the TENS unit also stimulate the body to produce natural pain relievers called endorphins, which are your body's natural pain-killing chemicals. Endorphins trigger your body's pain-relieving power, further blocking pain signals.
To use a TENS machine, first turn it off and use the controls to set the electric current. Plug the electrical wires into the machine, then place the sticky pads onto clean skin near the painful parts of your body, leaving a gap between the pads. Turn the machine on and slowly turn the dial until you feel a tingling sensation. This should not be painful.
It is important to check with your healthcare provider before using a TENS machine, as they can advise on the correct placement of the sticky pads and any alternatives if your skin is sensitive.

TENS units can be placed on acupuncture points to increase endorphin production
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive method of pain relief that works by delivering small electrical impulses through electrodes with adhesive pads attached to a person's skin. TENS units can be purchased at some pharmacies and online, and they come in various forms, such as a small device or a battery-powered device.
When using a TENS unit, it is important to first turn off the machine and use the controls to set the electric current. The electrical wires are then plugged into the machine, and the sticky pads are placed onto clean skin near the painful parts of the body, leaving a gap between the pads. The TENS machine can then be turned on, and the dial should be turned slowly until a tingling sensation is felt. It is important to note that this should not be painful.
The placement of the electrodes on acupuncture points may increase the effectiveness of TENS treatment. A review found some evidence that people who receive TENS through acupuncture points may experience a reduction in pain. Additionally, at least three studies have shown that acupuncture may increase endogenous opioids, which are the body's natural opioids, further contributing to pain relief.
It is recommended to consult a healthcare provider before using a TENS unit to ensure proper guidance on how and where to apply the electrodes.

Sticky electrode pads are placed on the skin, at least one inch apart
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive method of pain relief that uses low-voltage electrical currents to block pain or change one's perception of it. It is important to consult with a healthcare provider before using a TENS unit to determine the right device for your needs.
When applying the TENS machine, it is important to first turn off the machine and set the electric current using the controls. The sticky electrode pads should then be placed on clean, dry skin, with a gap between them, near the painful parts of the body. It is recommended that the pads be placed at least one inch apart in the appropriate dermatomal region of the targeted pain. The skin underlying the pad placement must have an intact sensation.
The TENS machine can then be turned on, and the dial should be turned slowly until a tingling sensation is felt. This sensation should not be painful. If the pads are not secure, changes in stimulation may occur, which could cause discomfort. The intensity of the electrical stimulation can be adjusted to a level that is strong but comfortable.
The placement of the electrode pads is important for the effectiveness of the treatment. Experts recommend placing the electrodes on acupuncture points to assist the body in producing endorphins. The number of pads used can also impact the level of stimulation and pain relief. If the area is large enough to accommodate four patches, for example, this will provide more stimulation and potentially greater pain relief.

Frequently asked questions
TENS stands for Transcutaneous Electrical Nerve Stimulation. It is a small, battery-powered device that delivers electrical currents to relieve pain.
First, ensure the machine is turned off. Clean and dry the skin around the painful area. Place the sticky pads onto the skin near the painful parts of your body, leaving a gap of at least one inch between the pads. Turn the machine on and slowly turn the dial until you feel a tingling sensation.
The intensity of the electrical stimulation can be adjusted to your preference. A higher intensity may provide more effective pain relief. However, it is important to start with a lower intensity and gradually increase it to a level that is strong but comfortable.
Research suggests that TENS is most helpful for chronic pain when used for at least 30 minutes while you are active. It is recommended to alternate between LF and HF TENS within each treatment session to prevent building a tolerance to the treatment.
It is important to consult your healthcare provider before using a TENS machine to ensure it is suitable for your needs. Individuals with pacemakers, epilepsy, or those who are pregnant are advised against using TENS. Additionally, do not use the machine while operating heavy machinery, driving, bathing, or swimming.
