TECAR therapy, also known as Capacitive and Resistive Energy Transfer, operates based on the principle of electromagnetic energy transfer. This therapy utilizes high-frequency currents that are applied through electrodes to the body. Capacitive mode targets superficial tissues, while resistive mode penetrates deeper layers. The energy transfer stimulates cellular metabolism, enhancing blood circulation, promoting tissue healing, and reducing inflammation. The electric fields created by the therapy generate heat, which increases tissue temperature. This temperature rise improves tissue extensibility, relaxes muscles, and facilitates pain relief. TECAR therapy's working principle revolves around promoting tissue repair, reducing pain, and improving overall function through targeted electromagnetic energy transfer.
