Should I choose a TENS or an EMS unit?
Before choosing which device is right for you, you should first ask yourself, what are you hoping to gain?
For example if you’re suffering with discomfort in your lower back, then a TENS device would be best. That’s because it would interrupt those pain signals being sent from your back to your brain.
If you need to build muscle, to improve your athletic performance, then an EMS unit would be better. The muscle contractions that happen when you use the unit can help to build strength and tone.
Some conditions would benefit from both TENS and EMS, for example if you were recovering from a muscle injury. EMS could help to speed up your rehabilitation, while TENS therapy might be useful for helping you cope with the associated pain.
