Tissue level
Energy can create warmth within the treated tissue, not only on the skin.
How TECAR therapy works
Energy created inside the treated area.
TECAR therapy uses radiofrequency energy to create controlled effects within the body. A clinician can adjust how that energy moves, how much warmth it produces, and which tissues receive the greatest emphasis.
Active treatment electrodeReturn electrode
The body completes the circuitEnergy travels through the treated area between the active and return electrodes.
The basic idea
The treated area becomes part of a controlled circuit.
Unlike a hot pack, TECAR does not simply place warmth on the skin. Radiofrequency current travels through the body, and the body’s natural resistance converts part of that energy into heat within the pathway.

Step 1 of 4
Energy begins at the device
The system produces a high-frequency alternating current. The frequency is high enough that TECAR is used for energy transfer rather than intentional muscle contraction or a tingling electrical sensation.
CET and RET
Two electrode types shape where the energy is emphasized.
Both modes use the same complete circuit. The difference is the treatment electrode and how its electrical field interacts with the tissue.

Capacitive energy transfer
CET emphasizes water-rich soft tissue.
The CET electrode has an insulating coating. This creates a capacitive field that places greater emphasis on more conductive, water-rich tissues such as muscle and superficial soft tissue.

This visual shows relative emphasis, not a hard boundary. Placement, power, frequency, tissue composition, contact, and technique all affect the pathway.
Power
Power changes current flow and warmth, but not at the same rate.
Lower-power treatment can transfer measurable current with little temperature change. As power rises, current increases and the warming effect becomes more pronounced.

Frequency
Frequency changes how quickly the field reverses direction.
Winback provides 300, 500, and 1000 kHz settings. The first visual shows the change in oscillation rate. The tissue view shows how Winback clinically frames the relative distribution of each setting.
300 kHz
Lower frequency, broader distribution
The field reverses direction 300,000 times per second. Winback clinically frames this as its most diffuse setting, often selected when the treatment plan includes deeper or denser structures.
These visuals compare relative treatment emphasis, not exact penetration depth. Frequency works together with CET or RET mode, power, electrode placement, tissue composition, contact, and treatment technique.
The five mechanics
Five ways to understand what may change during treatment.
These are overlapping parts of one response. They help connect the physics of TECAR to what a patient feels and what a clinician observes.
Biomechanical level
The area may feel less stiff and more workable during movement or hands-on care.
Neural level
Greater comfort may reduce guarding and make treatment easier to tolerate.
Circulation level
Local blood flow and oxygen delivery may increase around the treated area.
Cellular level
Early research is exploring how radiofrequency energy may affect cellular activity.
What this means in a session
TECAR supports the treatment. It does not replace the clinician.
A patient usually feels adjustable warmth while the clinician combines TECAR with the care already planned for that session.
Manual treatment
The treatment electrode can move with the clinician’s hands as they work on the area.
Movement and exercise
TECAR can be used while the patient performs guided motion, activation, or exercise.
Adjusted in real time
The clinician selects settings based on the goal, tissue, treatment technique, and patient feedback.
