Transcutaneous electrical nerve stimulation facts for kids
Transcutaneous electrical nerve stimulation, usually called TENS, is a way to help control pain using a small electrical current. It works by sending tiny electrical signals through your skin to your nerves. This method is often used by physical therapists and other healthcare professionals to help people feel more comfortable.

What is TENS and How Does It Work?
TENS stands for Transcutaneous Electrical Nerve Stimulation. "Transcutaneous" means "through the skin." So, it's about using electricity that goes through your skin to stimulate your nerves.
How Does TENS Help with Pain?
TENS units work in a couple of ways to help reduce pain. Imagine your body has a "gate" that controls pain signals going to your brain.
The Gate Control Theory
One idea is called the "gate control theory." When you use a TENS unit, it sends gentle electrical signals. These signals travel faster than pain signals. They can "close" the pain gate, stopping or reducing the pain messages from reaching your brain. It's like a busy highway where the TENS signals are fast cars that block the slower pain signals.
Releasing Natural Pain Relievers
Another way TENS might help is by encouraging your body to release its own natural pain-relieving chemicals. These chemicals are called endorphins. Endorphins are like your body's natural painkillers. When a TENS unit stimulates your nerves, it can cause your body to make more of these helpful chemicals.
What Does TENS Feel Like?
When you use a TENS unit, you usually feel a tingling, buzzing, or vibrating sensation. It should not be painful. The intensity can be adjusted so it feels comfortable and helpful.
When Is TENS Used?
TENS is used for many different types of pain. It's often used for long-lasting (chronic) pain or pain that comes from injuries.
Common Uses for TENS
TENS can be used for:
- Back pain
- Neck pain
- Arthritis pain (pain in joints)
- Muscle pain
- Pain after surgery
- Pain from sports injuries
Who Uses TENS?
TENS units are often used by physical therapists, doctors, and other healthcare providers. Sometimes, people can use TENS units at home after being shown how by a professional. It's important to always get advice from a doctor or therapist before using a TENS unit.
Safety and Important Notes
TENS is generally safe when used correctly. However, it's not for everyone.
When Not to Use TENS
There are certain situations where TENS should not be used. For example, people with pacemakers or certain heart conditions should not use TENS. It also should not be used on certain parts of the body, like over the eyes or on the front of the neck. Always follow the instructions from a healthcare professional.
TENS Is Not a Cure
It's important to remember that TENS helps manage pain, but it doesn't cure the cause of the pain. It's often used as part of a bigger plan to help someone feel better, which might include exercise, other therapies, or medicines.
