EMS fitness is also an FDA-cleared medical device but meant for muscle development. EMS fitness is designed to stimulate all the major muscle groups to elicit strength and endurance adaptations." [12] In the case of TENS, the current is usually sub-threshold, meaning that a muscle contraction is not observed. [original research?]
