How Does Electrapy EMS Massager Work? - Electrapy EMS Massager Reviews
Stick-on devices like the Electrapy EMS Massager that deliver electrical stimulation to specific muscle groups are affixed to the skin. The control unit then sends currents to the targeted muscles. The timer, sensing knobs, and other components that create the electric current are housed in the control unit. Two lead wires and two to four neurostimulation electrodes transfer the electricity via the skin. These electrodes reside in the wing-shaped parts of the Electrapy EMS Massager. When activated and used on a particular muscle group, the equipment may produce tingling sensations.
