What's High Frequency(HF) Therapy and How Does It Work?


High Frequency (HF) Therapy is a non-invasive electrotherapy using currents above 100 kHz for pain management and tissue repair. A key advanced form is TECAR Therapy (Capacitive And Resistive Energy Transfer)—the core of Longest’s HF Device and top radiofrequency equipment.

 

Operating at 300 kHz~1 MHz, TECAR uses capacitive/resistive electrodes to interact with tissue, generating controlled heat via natural tissue resistance/capacitance. This boosts circulation, accelerates cellular metabolism, and stimulates natural regeneration—safe, targeted, and comfortable. Longest’s device adds intuitive operation and versatile modes, ideal for clinics/hospitals.

FAQs

High Frequency Therapy Device
What is the core therapeutic principle of the device?

The device adopts TECAR Therapy (Capacitive And Resistive Energy Transfer Therapy), which uses 300KHz~1MHz non-invasive high-frequency current. Through the interaction between capacitive/resistive electrodes and human tissues, it raises tissue temperature, stimulates the natural regeneration of cells, and accelerates metabolism.

What is the difference between Capacitive Mode (CET) and Resistive Mode (RET)?

Operation method: CET requires continuous movement of electrodes, while RET is a fixed operation; Target area: CET acts on superficial, high-moisture, low-impedance tissues (such as dermis, muscles, fascia), and RET targets deep, low-moisture, high-impedance tissues (such as ligaments, tendons, bones, joints).

Which conditions is the device suitable for?

It can assist in treating various musculoskeletal system-related conditions such as tendinitis, joint pain, muscle strain, neck/low back pain, slipped disc, gonarthrosis, and distortion. 

Which populations or conditions are contraindicated for the device?

Contraindicated populations include patients with bleeding, cancer, phlebitis/thrombi/arteriopathy, decreased sensitivity in the treatment area, and those with metal prostheses/pacemakers/hearing aids/insulin pumps/intrauterine devices in the body, as well as patients with fever/infection, pregnancy, epilepsy, and children under 14 years old.

What therapeutic effects can be achieved?

Core effects include relieving pain, reducing inflammation and swelling, promoting tissue repair, and accelerating blood circulation and metabolism.
