TENS Therapy in Physiotherapy: What It Is, How It Works & Who Needs It

What Is TENS Therapy?

TENS stands for Transcutaneous Electrical Nerve Stimulation. It delivers low-voltage electrical impulses through electrodes placed on the skin, stimulating nerve fibres and modulating pain signals. It is a drug-free, non-invasive pain management tool used in physiotherapy clinics and increasingly available for home use.

How Does TENS Work?

Two main theories explain TENS effectiveness: 1. Gate Control Theory (high-frequency TENS): The electrical stimulus activates large-diameter nerve fibres (Aβ), which block pain signals from smaller pain fibres (Aδ and C) at the spinal cord level, essentially 'closing the gate' to pain. 2. Endorphin Release (low-frequency TENS): Low-frequency TENS stimulates the release of endogenous opioids (endorphins and enkephalins), providing analgesic effects lasting beyond the treatment session.

💡 TENS provides pain relief during and immediately after application but does not treat the underlying cause. It is most valuable as a component of a physiotherapy programme to manage pain while exercises and manual therapy address the root cause.

Should You Buy a TENS Machine for Home Use?

Home TENS machines are available and can be effective for chronic pain management between physiotherapy sessions. However, Dr. Maitri Kothari recommends getting professional guidance first on electrode placement and settings for your specific condition. Incorrect electrode placement can be ineffective or, in some cases, contraindicated.
