What Is TENS Therapy?
TENS Therapy is a noninvasive treatment that sends mild electrical pulses through skin electrodes to affect nerve signals and ease pain. A small battery-powered device controls the pulse pattern and strength. TENS may support pain care for muscle, joint, nerve, or other pain, but results vary by person and condition.

Key Takeaways About TENS Therapy
- TENS works through skin electrodes, without placing a device inside the body.
- A portable stimulator controls the pulse pattern and strength.
- TENS is not the same as Peripheral Nerve Stimulation.
How TENS Therapy Works

TENS Therapy sends low-level electrical pulses through electrodes placed on the skin. The pulses may change how nerves send pain signals to the brain. They may also support the body's natural pain control signals.

A TENS unit lets the user adjust the pulse pattern and strength. Treatment does not place an electrode inside the body. TENS can be part of a broader pain plan, while Peripheral Nerve Stimulation targets a selected nerve with a separate treatment approach. A clinician considers the pain location, symptoms, and treatment goals before choosing an approach.
How TENS Differs From Peripheral Nerve Stimulation
TENS is applied through the skin and is commonly used for short-term symptom control. Peripheral Nerve Stimulation places stimulation near a specific peripheral nerve. The two approaches share the idea of changing nerve activity, but they differ in how the electrical signal reaches the nerve.

From the Premier Injury Specialists team
When we discuss TENS Therapy, we review the pain pattern and the goal of stimulation. We also separate TENS from Peripheral Nerve Stimulation because the treatments reach nerves in different ways. Our team considers whether surface stimulation fits the person’s broader pain plan.
TENS Therapy in Practice: A Real-World Example
A person with ongoing shoulder pain may try TENS Therapy with electrodes placed near the painful area. The surface pulses may provide temporary symptom relief while the care team considers whether Peripheral Nerve Stimulation fits the treatment plan.
