Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, is the elicitation of muscle contraction using electric impulses.
TENS vs EMS: the main difference between the two: 1  TENS stimulates the nerves â the rationale being that the simulation keeps pain signals from reaching the brain. 2  EMS causes the muscles to contract â by mimicking the action potential that comes from the central nervous system.
