Omron HVF021 TENS Unit — the most trusted TENS machine available in India. Medical-grade quality, 6 pre-set modes, widely used by physiotherapists. Available on Amazon.in for ₹3,000–5,000.
TENS (Transcutaneous Electrical Nerve Stimulation) is a physiotherapy technique that uses low-voltage electrical pulses to disrupt pain signals. When electrode pads are placed near a painful area, the electrical pulses travel through the skin and stimulate nerve fibres, effectively "blocking" pain messages from reaching the brain — the same principle as rubbing a spot that hurts.
TENS also triggers the release of endorphins — the body's natural painkillers. The result: temporary but genuine pain relief, drug-free, with no significant side effects for most people.

How to Use TENS for Lower Back Pain
Electrode Placement
Place pads on either side of the spine at the painful area — never directly on the spine. For lower back pain, place pads in the lumbar region, 2–3 cm from the spine on each side. For a four-pad setup, place two pairs vertically along the paraspinal muscles.
Settings Guide
| Acute pain / muscle spasm | 80–100 Hz (high frequency), low intensity |
| Chronic back pain | 2–4 Hz (low frequency), moderate intensity |
| Session duration | 20–30 minutes per session |
| Frequency | 2–3 times daily maximum |
| Intensity | Start low — should feel tingling, not pain |
Safety — Who Should NOT Use TENS
⚠️ Do NOT Use TENS If You Have:
- A cardiac pacemaker or defibrillator
- Epilepsy
- Pregnancy (especially first trimester)
- Active cancer in the treatment area
- Open wounds or skin infections at electrode site
- Deep vein thrombosis (DVT)
Also: never place electrodes on the front of the neck, over the eyes, on the chest, or directly on the spine.

FAQ
Yes — TENS provides clinically supported temporary pain relief. It works best for chronic lower back pain, muscle spasms, and sciatica flares. It doesn't cure the underlying cause but can significantly reduce pain intensity and improve quality of life. Many Indian physiotherapists use TENS as part of standard back pain treatment.
Different mechanisms — heating pad works best for muscle stiffness and chronic tension. TENS works better for nerve-related pain, acute spasms, and sciatica. Many people combine both: heat first to relax muscles, then TENS for pain signal blockade. If buying one, a heating pad is more versatile for most Indian users.
Maximum 2–3 sessions of 20–30 minutes per day with at least 1 hour between sessions. Allow the skin to rest. Do not sleep with TENS pads on and do not use continuously.
Yes, if you plan to use TENS regularly for ongoing back pain management. The build quality, reliability, and consistency of the Omron justify the higher price versus budget units. For occasional use, a budget unit at ₹800–1,500 is sufficient.
Yes — TENS is effective for sciatica pain relief. Place electrodes near the lumbar spine (source of sciatic nerve) or along the sciatic nerve path in the buttock/thigh. Use low frequency (2–4 Hz) for chronic sciatica. It provides temporary relief but does not treat the underlying disc or nerve compression causing sciatica.
