TECAR therapy as a system of Capacitive and Resistive electric transfer , which is one of the methods used in diathermy , was developed as a form of deep thermotherapy , delivers radiofrequency ( RF ) energy , which passes between active electrode and inactive electrode , and generates heat in the human body.

EMS " Electrical Muscle Stmulation is an internationally accepted and proven way of treating muscular injuries . It works by sending electronic pulses to the muscle needing treatment this causes the muscle to exercise passively . When the muscle receives this signal , it contracts as if the brain has sent the signal itself . As the signal strength increases , the muscle flexes as in physical exercise . Then when the pulse ceases , the muscle relaxes and the cycle starts over again (Stimulation, Contraction and Relaxation .)
