What is TENS?
TENS stands for transcutaneous electrical nerve stimulation. It is a small battery-powered unit connected by wires to sticky pads on your skin.
The unit sends mild electrical pulses that most people feel as a buzzing or tingling. Some find that this eases pain while the unit is on.
Why does it matter for a patient or family?
TENS may give short-term relief, which can make it easier to walk, sleep or do your exercises. It does not fix the cause of pain, so it works best as a helper to movement, not a replacement.
Families sometimes buy a unit from a shop. It is wise to ask a physiotherapist first about settings and where the pads should go.
An everyday example in Ipoh
An older woman with long-standing back pain finds the pain flares in the afternoon heat while she waits for dinner to be cooked. With the physiotherapist’s advice she uses TENS for part of the afternoon, then does her gentle stretches while the pain is quieter.
Her daughter, who lives in Penang, learns the pad positions through photos sent on WhatsApp.

Safety and where it fits
