Nerve Stimulator vs. TENS vs. PEMF

If you’re exploring non-invasive options for pain relief and nerve health, you’ve likely heard of nerve stimulator therapy, TENS therapy, and PEMF therapy. All three are drug-free approaches used in chiropractic, physical therapy, and functional medicine practices - but they work in very different ways. Understanding these differences can help you and your clinician choose the best option for your unique needs.

Nerve Stimulator

The nerve stimulator is an advanced form of pulsed radiofrequency (PRF) therapy that uses a handheld probe to target specific peripheral nerves with a unique waveform that combines traditional stimulation with high-frequency electromagnetic energy. This waveform travels along the nerve, interacts with nerve mitochondria, and helps restore natural nerve function and reduce chronic pain. It’s used for conditions like neuropathy, sciatica, radiculopathy, and other persistent nerve-related pain.

Key features:

• Targets specific nerves with a patented waveform

• Stimulates nerve repair at a cellular level

• Can deliver long-lasting relief after just a few short treatments

• Non-invasive with minimal discomfort during application

TENS Unit

Transcutaneous Electrical Nerve Stimulation (TENS) is one of the most common electrical stimulation therapies. It uses electrode pads placed on the skin to send small electrical currents into nerves. These impulses help block or “scramble” pain signals before they reach the brain and can trigger the release of natural endorphins — the body’s own pain-relief chemicals.

What TENS is good for:

• Acute pain relief

• Tension and muscle soreness

• Short-term discomfort (e.g., post-exercise aches)

  
  

Limitations:

• Pain relief often only lasts while the unit is active

• Does not directly support long-term healing or nerve repair

• Requires direct skin contact via pads

PEMF Therapy

Pulsed Electromagnetic Field (PEMF) Therapy uses pulsed electromagnetic fields — typically generated by coils — to penetrate deep into tissues, bones, and cells without touching the skin. PEMF is believed to support cellular processes like ion exchange, circulation, and enzyme activity, which may promote tissue healing, reduce inflammation, and improve general function.

Benefits of PEMF:

• Works without direct skin contact

• Can affect larger areas or even whole-body systems

• May support cellular repair and recovery, not just pain management

• Comfortable and suitable for sensitive areas

Which Is Best for You?

• Choose a nerve stimulator if you’re dealing with chronic nerve pain, neuropathy, or conditions that have not responded well to typical therapies. This therapy is designed to go beyond symptom management and help restore nerve function.

  
  

• Choose TENS when you want temporary pain relief for muscle soreness or acute discomfort that doesn’t require deep tissue or nerve repair.

  
  

• Choose PEMF if you want support for cellular healing, reduced inflammation, and deeper tissue recovery, and you prefer a contactless treatment experience.
