What is electrical muscle stimulation (EMS)?
EMS stands for electrical muscle stimulation. The device sends gentle electrical pulses through the skin, by means of pads or electrodes, and those pulses make the muscle contract and relax. It feels like tingling or small rhythmic taps. The intensity is always adjustable.
EMS and TENS are not the same
Both use electrical pulses, but they aim at different things. EMS acts on the muscle and causes visible contractions. TENS acts on the nerves in the skin and produces a tingling sensation without contracting the muscle. Some devices include both modes.
On home massagers, EMS is offered as a massage sensation. It does not replace exercise or a treatment prescribed by a health professional.
Safe use
Electrical stimulation should not be used by people with a pacemaker or other implanted electronic devices, by pregnant women, or by anyone with epilepsy or heart problems, unless a doctor advises it.
Electrodes are not placed on the head, the front of the neck, the chest, or on broken or irritated skin. Always start at the lowest intensity and keep to the session time the manufacturer states.
What to check before you buy
- Look for several intensity levels so you can start gently.
- Check whether the pads or conductive gel are replaceable and easy to find.
- Value automatic shut-off at the end of the session.
