PEMF and TENS are commonly confused but completely different. TENS (Transcutaneous Electrical Nerve Stimulation) sends an electrical current through skin electrodes to interrupt pain signals at the nerve — fast pain relief, no underlying healing effect. PEMF (Pulsed Electromagnetic Field) passes magnetic pulses through tissue at the cellular level — slower pain relief, but acts on underlying inflammation and supports tissue repair. Use TENS for acute pain control. Use PEMF for chronic conditions and recovery. They work well together.
| TENS | PEMF | |
|---|---|---|
| What it is | Electrical current via skin electrodes | Pulsed magnetic field via mat or applicator |
| Mechanism | Blocks pain signals at the nerve | Stimulates cellular voltage, reduces inflammation, supports repair |
| Depth | Surface only | Whole-body, deep tissue |
| Sensation | Tingling / pulsing | Usually nothing felt |
| Effect duration | During use only | Cumulative, lasting |
| Best for | Acute pain spikes | Chronic pain, recovery, healing |
| Cost | £15–£100 home unit | £25–£75 clinic session, £200–£3,000 home |
| FDA-cleared | Yes — pain relief | Yes — multiple indications since 1979 |
When to use which
Use TENS for: acute pain spikes you need to manage in the moment, post-injury short-term relief, labour pain, chemotherapy-related neuropathy short-term.
Use PEMF for: chronic pain conditions, joint OA, post-surgical recovery, sports recovery, healing-focused use cases.
Use both when: chronic pain has acute flare days. TENS in the moment, PEMF for the long-term work.
Contraindications
TENS and PEMF share contraindications: pacemakers, defibrillators, electronic implants. PEMF additionally contraindicates pregnancy (over abdomen) and active malignancy.
Frequently asked questions
Are PEMF and TENS the same thing?
No. They are completely different technologies. TENS sends an electrical current through skin electrodes to mask pain signals at the nerve. PEMF passes pulsed magnetic fields through tissue without skin contact, working at the cell membrane to reduce inflammation and stimulate repair.
Which works faster for acute pain?
TENS — it blocks the pain signal in real time. PEMF works slower but addresses underlying inflammation rather than just masking pain.
Which works better for chronic pain?
PEMF, generally. Chronic pain is driven by underlying inflammation, central sensitisation, and tissue damage — things PEMF acts on. TENS only blocks signals during use.
Can I use both?
Yes. They are complementary. Many clinical patients use TENS for short-term relief and PEMF for longer-term healing.
