Electric Muscle Stimulator (EMS) is advised to tone, firm, and strengthen body muscles. EMSs are used in Physiotherapy to re-strengthen injured areas and to burn fat. It works by attaching Stuck-on pieces of equipment to the skin and using a controlling unit to transmit currents to a group of targeted muscles. It has a timer, sensory knobs, and other tools for generating the electric current. Two to four neuro-stimulation electrodes and two lead wires are attached to the skin to pass the current.
