TENS is an acronym meaning Transcutaneous Electrical Stimulation. What that means is that the device sends low voltage electrical currents to the body.
This electrical stimulation works on the “gate-theory” that states if electrical stimulation can be sent on a quicker, higher frequency than the flow pain signals, it can decrease the individual’s perception of pain.
A TENS machine is usually small devices, making it easily transportable. Most devices can be clipped on the waist. The device has 4 electrodes that are applied to the desired area to be treated.
A Physiotherapist can teach their clients how to apply and use the machine correctly. Newer devices have wireless electrodes and can even be operated from their own phones.
